AnaLee and Tyson’s Great

Race

(2)

Today’s the big day! AnaLee and Tyson are going to have a

swimming race against Zack and Miya, a couple of big kids from the high school. They meet at Maili Beach and split up into teams. When the kids meet up, AnaLee stares in amazement at the high

schoolers, “Wow, they are REALLY big, I hope we can beat them!”

Today’s the big day! AnaLee and Tyson are going to have a

schoolers, “Wow, they are REALLY big, I hope we can beat them!”

They decide they will have two races. AnaLee and Zack will race first. Then it will be Tyson and Miya’s turn. Tyson and Miya paddle out to the “waiting rock” on boogie boards where they will wait for their turn to race. AnaLee and Zack wait on the beach.

As Tyson and Miya paddle out to the waiting rock, a small wave comes and

pushes them a little bit. Then a HUGE wave comes and pushes them almost

the whole way to the rockWow, that was an easy trip. That big wave

really made us go fasterMiya said to Zack.

Little force = Little acceleration (Little wave)

pushes them a little bit. Then a HUGE wave comes and pushes them almost

the whole way to the rockWow, that was an easy trip. That big wave

really made us go fasterMiya said to Zack.

Newton’s 2nd Law says if an unbalanced force acts on an object, the object will accelerate. The small wave puts a small force on the boogie boards and speeds it up a little. The big wave speeds them up a lot.

All the kids yell together,

“Ready,Set,Go!” AnaLee and Zack both jump into the water and start swimming towards their teammate on the rock.

“Push really hard in the water, AnaLee, and the water will push you forward.” Zack kindly tried to help the younger swimmer.

I am pushing as hard as I can. I bet you I will win” said AnaLee.

Newton’s 3rd Law says forces come in pairs. The force of the hand on the water equals the force of the water on the hand. So when Zack and

The wave accelerated AnaLee much more than Zack and she took a big lead in the race!

AnaLee wins! She and Zack climb onto the “waiting rock”. AnaLee taps

Tyson on the back. “Now it is your turn!”. Zack and Miya jump into the water.

“Go Tyson Go!” yell Tyson’s friends. “Go Miya Go” yell Miya’s friends. Tyson tries to copy what AnaLee was doing to try and go faster through the

water. He learned that if he pushes the water with his hand then the water

The race is over and Tyson and AnaLee win the race. In order for AnaLee and

Zack to get back to the beach they have to get on the boogie board. They

surf back to the beach but the only problem is that Zack doesn’t remember

going which made them fall into the sand.

Everyone came over to see if they were ok. They looked up at all of their

friends and laughed. Zack helped AnaLee up. They watch the end of the

race between Tyson and Miya. They see that maybe both of them were

going to win but Tyson starts to paddle faster. He can tell that Miya is tired

Tyson paddles and paddles. “Come on Tyson! TYSON! TYSON!” Everyone

cheers Tyson on. Tyson paddles and paddles. He reaches the beach.

Tyson goes over to Miya and shakes her hand. “Good race, Miya.” Tyson also told her that she was swimming so fast that he wasn’t sure whether or not
