Mind Map

The Mind Map displays the organization and relationship between the concepts and activities in this Learning Guide in a visual form. It is included to provide visual clues on the structure of the guide and to provide an opportunity for you, the teacher, to reorganize the guide to suit your particular context.

Stages of Learning

The following stages have been identified as optimal in this unit. It should be noted that the stages do not represent individual lessons. Rather, they are a series of stages over one or more lessons and indicate the suggested steps in the development of the targeted competencies and in the achievement of the stated objectives.

1. Activating Prior Learning

This stage aims to engage or focus the learners by asking them to call to mind what they know about the topic and connect it with their past learning. Activities could involve making personal connections.

Background or purpose

Soil is one of the most important resources on earth. The aim of this unit is to increase students' awareness on its importance to human, plants and animals and share

responsibility in taking care and protecting it.

To asses students' understanding about soil, they will be asked what they know and wanted to know about it using the KWL Chart. They will be working individually first and then in groups to talk about their initial understanding on soil.

Strategies for activity 1

(4)

After you and the students decide what you want to learn in the topic or unit you may post the list on a wall to refer to it as you cover the information. Keep it up for the entire course or unit and mark the class progress.

2. Brainstorming is a process used in generating many ideas. Rules:

• quantity not quality

• be free-wheeling, anything goes

• hitch-hiking on other's ideas is to be encouraged. • No criticism is allowed

• writer must write as said – no paraphrasing

3. Card Clusters is a strategy in collecting information/ideas in an organized visual form. The students will write their responses to a question in a card (one idea per card). As a teacher, cluster the cards according to responses. Do not over cluster cards and be clear on the meaning of each cluster.

Activity 1: Digging Up

Option 1

1. Organize students into groups.

2. Show letters I O L S and ask each group to form a word using all the letters. You may provide them with clue/clues to form the word soil.

3. After the groups had formed the word SOIL, ask them what they know and wanted to know about it.

4. Show and explain a KWL Chart on Soil. Inform them that they are going to fill up the first two columns on what they Know and Wanted to know about soil.

5. Distribute KWL Chart on Soil to every member of the group and let them fill up the “What I Know” and “What I Want To Know” columns individually for 8 minutes. Please see activity 1 on page 14.

6. As a group, have them talk about what each of them wrote on their individual KWL Chart on Soil and choose the top five ideas which most of them know and wanted to know. Let them write their responses on idea cards (one idea per card) and ask them to paste on the Class KWL Chart on Soil posted on the wall (Please see Activity 2 page 16.

Prepare the Class KWL Chart ahead of time.

7. Group the cards which contain the same ideas and highlight those which will link to the topic to be discussed.

Option 2

1. Organize students into groups.

2. Show letters I O L S and ask each group to form a word using all the letters. You may provide them with clue/clues to form the word soil.

3. After the groups had formed the word SOIL, ask them what they think SOIL is? 4. Have each group discuss about the question and write their responses onto cards and

(5)

5. Group the cards according to responses. The same ideas will be clustered. Keep these ideas on the board and revisit these responses after the lesson.

Formative Assessment

Move around while the pupils are recording their responses on K and W column for KWL Chart on Soil and during the group discussion. Check and assist students who might have difficulty in expressing their ideas. Make sure that each students write at least two ideas on KW columns.

For option 2, move around from one group to the other while they are discussing on what they think soil is. In clustering the idea cards, you may do it or ask some students to group the idea cards and come up with an organized thought of what they think soil is.

Roundup

The pupils should be able to:

• record and share their initial understanding about soil; • ask questions about soil.

2. Setting the Context

This stage introduces the students to what will happen in the lessons. The teacher sets the objectives/expectations for the learning experience and an overview how the learning experience will fit into the larger scheme.

Background or purpose

The students will be shown a mind map of the topic with blank boxes for them fill in after every lesson. Questions will be posted on the board to keep their focus on the topic. This activity is given to provide clear direction while they perform various activities.

Strategy for Activity 3

Goal Setting – Setting goals in a classroom situation occurs where students and/or teachers set targets, objectives or outcomes for students to work towards achieving over a period of time. It can be very meaningful where a student sets his/her own realistic goal. To be effective, goals need to be both achievable and challenging.

Activity 3 - Soiled Map

1. Show a partially filled mind map to the class ( Please see Teacher Resource Sheet 1 page 18) and explain to them that it is a map of the lessons that they are going to explore. Tell them that they will complete the map as the lesson progresses. 2. Tell the students that they will be performing several activities to help them

understand the topics.

3. You may post the following questions on the board so that students will be guided as they perform the activities:

• What is soil made of?

• Are all soil samples the same in all places? • How can we use each kind of soil?

(6)

• How does pollution affects soil productivity? • How can we take care/protect the soil?

Roundup

The pupils should be able to see the big picture of the topic and are now ready for the activities which will help them answer the questions above.

3. Learning Activity Sequence

This stage provides the information about the topic and the activities for the students. Students should be encouraged to discover their own information.

Background or purpose

This stage provides several hands-on activities which may help students develop an understanding on: the basic components of soil (minerals and organic materials), kinds of soil, ways people use soil, practices that cause soil pollution, how pollution affects soil productivity and ways in taking care or protecting the soil. These topics aim to answer the skills needed in BEC Competencies VI. 2.1 – 2.5.

The students will be using their observation skills while conducting investigations on soil. They will make predictions, inferences, answer questions and draw conclusion from the gathered information.

Strategies for Activity 4

1. Note making Framework is used to assist students organize their research. Once they get some information, students fill it in the framework.

2. Guided Design encourages interaction in small groups. Here the focus is on developing learner's decision making skills as well as on teaching specific concepts and principles. Students work to solve open-ended problems which require outside class work to gather information. This format encourages learners to think logically, communicate ideas and apply steps in a decision-making process. Learners are also required to apply the information they have learned, exchange ideas, and reflect on suggested solutions. The teacher's role is to act as a consultant to the groups.

Activity 4 - Home Under My Feet

Advance Preparation

1. Choose several locations in your school campus where the students can dig and take soil samples. These locations should be safe for them. In case circumstances will not permit the students to dig soil from your school campus, you may provide them with soil samples from different locations.

2. Prepare materials for every group like hand lens , shoe box or any available container for the soil, rubberized gloves/cellophane, puller, trowel/shovel, transparent glass jar with cover, water, table covered with newspaper or any used pieces of paper, and activity sheets.

During the session

(7)

2. Set safety measures before letting the students perform the activity. Below are some points to consider:

• Wearing of rubberized gloves/cellophane when taking and examining soil samples • Washing of hands after the activity

• Handling magnifying lens and sharp objects with care. 3. Build the vocabulary of the words rough, smooth and gritty.

4. Distribute the materials they need in taking soil sample and lead them to the location you have chosen before the lesson started. Each group should put the soil sample in a container.

5. After the activity, bring them back to the classroom and let them examine the soil sample carefully using magnifying glass and and their bare hands to feel it.

6. Distribute Student Activity 4. Please see page 20 - 20.

7. After the activity, ask a representative from each group to share his/her group's output. Have enough time to process their answers by asking follow up questions that lead to the development of concept on the basic components of soil

8. Provide lecturette on the two basic components of soil (organic matter and minerals) which the students had seen .You may also tell the students that there are two other important components of soil, the air and water . Introduce the word Humus.

Strategy for Activity 5: Guided design

Activity 5: A Closer Look at Soil

Advance preparation:

1. Collect soil samples of sand, silt, clay and loam. Put each kind in small separate packs. Each group should be provided with the four kinds of soil.

2. Label each container with the following code: A. for sand, B for Silt, C for Clay and D for Loam

3. Prepare an area where the students can work/perform the activity.

During the session

1. Using the same group, ask students with this question: Are all soil samples the same in all places? Publish their answers on the board and revisit it after the lesson.

2. Introduce the activity. Explain to them that they are going to examine soil samples to see if they are the same in all areas.

3. Build the vocabulary of the word texture by letting them feel and differentiate sandpaper and cotton or any surface with different textures. You may ask them to cite words which describe texture.

4. Show them the materials they need in performing the activity. Remind them to handle the hand lens carefully, wear rubberized gloves/cellophane when examining the soil, take extra care not to mix the soil from other packs and wash their hands after the activity.

5. Assign a place for each group to examine the soil samples.

(8)

7. Let the students share their output to the the class. Have enough time to process their answers.

8. Help them develop a working definition of sand, silt, clay and loam.

9. Provide lecturette on the different kinds of soil. Show the Soil Shake, their output made in Activity 4 “Home Under My Feet” and explain what each layer mean. You may also include the importance of knowing the texture and color of the soil.

Strategy:

Small Group Discussion is a strategy used to generate ideas on a certain topic from all students in a limited time. This is done to increase the student -student interaction and to encourage participation of every student especially in expressing his/her ideas.

Activity 6 – Hidden Treasures

1. Start the session by asking the students to close their eyes and imagine a world without soil. Then ask, “How will it look like without soil?” “What do you think will happen to people, plants and animals?”

2. After a minute, ask them to open their eyes and let them answer the questions. Publish their answers on the board.

3. Organize the students into 4 groups. Tell them that they are going to color a drawing according to its number code. This will show how people use soil.

2. Put at least 3 objects in the cellophane or box that you prepared and give it to the group during the activity.

During the lesson

1. Show the two potted plants to the class. Have them describe and compare the

condition of the plants and the soil where the plants grow. Ask the following questions to lead the discussion on soil pollution:

(9)

c. If you were a plant, in which pot would you like to live? Why?

d. What do you think makes the soil healthy? What makes them unhealthy? 2. Publish students answers on the board.

3. Build the vocabulary of the following words pollution,polluted soil

pesticides/herbicides, inorganic fertilizer, poisonous and harmful. Explain to the pupils that these words will help them understand their lesson on practices that cause soil pollution.

4. Organize students into groups for an activity.

5. Distribute activity sheet 7, ( page 29 ) and a pack of garbage to every group. Have them discuss among themselves the answers to the questions given in the activity sheet. 6. After the discussion, have each group report their output.

• compare the different kinds of soil and identify ways which each can be used; • identify ways people use soil;

• infer causes of soil pollution;

• compare polluted and non polluted soil as to its productivity; • suggest ways of protecting the soil.

4. Check for Understanding of the topic or skill

This stage is for teachers to find out how much students have understood before they apply it to other learning experiences.

Background or purpose

In this stage, the students will perform activities to assess their understanding on the topics about soil. As a teacher, you may choose activity/ies which fit to the needs of your students. You can use some of these activities for formative evaluation by letting them work in groups but answer questions in activity sheet individually. Rubrics are provided for you to mark your students.

Strategy: Game

(10)

sustain their interest because of the challenges it pose, provide opportunity for the students to interact and communicate and increase respect and cooperation.

Activity 8 – Let's Play and Learn

Option 1. - Pass the Ball and Hanky

This is an activity where the students have an opportunity to play and at the same time learn.

The students will be seated in a circle facing the center. A ball and a handkerchief will be passed around while the music is playing or while the students are singing. When the music/singing stops,whoever gets hold of the ball will be the one to ask question about the lesson and whoever gets hold of the handkerchief will be the one to answer the question.

Option 2. - Cabbage Pass

This is an activity where students answer questions about the topic. The teacher will prepare questions in sheets of paper (one question/sheet). Form these sheets into one cabbage – like ball.

During this activity, the teacher may call a student to throw the cabbage to a pair/group. The pair/group then will peel off a sheet and answer the question written in the sheet while other pairs/groups listen. After they had given their answer, they will pass the cabbage to other pair/group. The group who gets hold of it will do the same, until all the groups have answered the questions.

Background or purpose

The activities in this stage aim to help the students use their learning about soil in different situations.

Activity 12 Cinquain Poem

The students will be working in groups of three to make Cinquain Poem About Soil. A Cinquain ("cin-kain")is a 5 line poem. It comes from the French word “Cinq” which means five. Itfollows the pattern below:

1st line - one word - title

2nd line - two describing words about the subject

3rd line - three action words that describe something the subject of the poem does 4th line - four feeling words or phrase that indicates a feeling related to the poem 5th line - synonym for title/ a noun that sums what the poem is about.

Source:http://www.edu.pe.ca/bloomfield/grassroots/Poetry/Cinquain.htm

Move around and check students' output. Have a quick talk in every group, asking them about the things they do.

Roundup

The students should be able to apply what they learned from the lessons they have via the activities above.

6. Closure

This stage brings the series of lessons to a formal conclusion. Teachers may refocus the objectives and summarize the learning gained. Teachers can also foreshadow the next set of learning experiences and make the relevant links.

Strategy KWL (What I Learned)

Activity

The pupils will be working individually first. Each of them will be working on their individual KWL Chart and fill in the “What I Learned” column. Ask them to share this learning with their group mates. Together, they will fill up the “What We Learned column of the group KWL Chart. They will also match the first column that they previously filled in ( What I Know) with the third column that they just filled in (What I Learned) and make necessary adjustments if what they previously know did not match with what they learned.

At this stage, the blank Soiled Map previously shown and posted on the wall should have been completed by them.

Formative Assessment

Keep everyone involved and make sure that everyone is filling in the individual KWL Chart and involve themselves in group discussion.

Background Information for Teachers

Soil

Soil is the uppermost covering of the earth. It is made up of mineral particles, and decayed plants and animals.

Soil forms very slowly from rocks by weathering. This process takes hundred or even thousands of years. However it can be destroyed easily in seconds.

Soil is different in many ways. They can be different in color and texture.

The color of soil tells how fertile it is. It ranges from black or dark brown to white. A black or dark brown colored soil is best for growing plants because it contains much humus (see metadata for the definition).

Soil's texture can be rough, smooth or gritty. It tells the size of mineral particles and identify how water run through it.

The most common type of soil are the sand, silt, clay and loam. The sand has the largest particle. Its grains can be seen and felt. It does not hold water. Some of the places where we can find sand is on beaches, rivers and desserts. The medium – sized particle is the silt soil. Its particles are large enough to be seen. Its texture can be likened to a flour ( smooth). Clay, on the other hand, has the finest particle. Its grains can not be seen by our eyes. It holds much water because they are packed tightly. It is sticky when wet but very hard when dry. It is difficult to cultivate clay soil since it prevents the growth of plants and the circulation of air around the roots. However, a certain amount of clay is a desirable constituent of soil because it binds other kinds of particles together making it retentive of water. Loam soil is a mixture of sand, clay and silt soil. This kind of soil is best in growing crops because it contains humus which is essential to plants.

Soil is used in various ways by people. They use it: 1. as foundation of homes, schools and buildings 2. as materials for building construction

3. to grow plants and crops 4. to build roads

5. to make jars/pots and decorations Soil is also used as home to organisms (plants and animals) and it filters water.

Soil pollution is the degradation of soil's quality

making it less useful. Soil may be polluted when chemicals or any harmful substances are mixed with it. They kill organisms that live in the soil. These organisms are responsible in breaking down waste and make the soil fertile.

Human activities contributed much to the pollution of soil. Some of these activities are: 1. Improper disposal of wastes/garbage which contain heavy metals, chemicals, oil and other harmful substances. Some of these wastes come from homes. Examples are battery/dry cell, kerosene, oil, oil based paints, stain remover, etc.

4. Burning/Kaingin system of farming - This damages soil. It kills microorganisms which are responsible in renewing soil fertility.

5. Demolition and construction – Non biodegradable debris settle in soil. 6. Wastes from factories – These wastes contain harmful substances.

7. Over Farming – it drains the soil so that it becomes difficult for plants to grow in it.

Pollutants remain in the soil for several years affecting its productivity and fertility. This is the reason why polluted soil can no longer grow healthy plants/reduced yields and may not be able to support people for food.

Soil forms thousands of years. Since most life depend upon it, there is a need for us to conserve soil. Conservation means maintaining the quality of soil. We can do this by:

1. disposing our garbage properly. Segregate those which can be decomposed, recycled and those that are hazardous.

2. planting trees

3. rotating crops we plant 4. avoiding kaingin farming

5. putting dried leaves/grasses in a compost pit instead of burning
