2S - Science

In science this afternoon we made predictions and tested them. We wanted to know what would happen to our heart rate when we exercise, and who had the biggest puff. Here are our predictions:

Who will have the most puff?Finley C because he is the biggest. – Emma
Luka because I am older – Luka
Billy because he is the most sporty. – Sophia
Jack K because he is the fastest. – Seth
Sienna because she is quite tall. – Isabel R
Girls won’t have the most puff because they won’t have as much breathe as the boys. – Jack H
Boys will have more puff Will excercise make our heart beat faster?It will go faster because it will give you more energy. - Elliott
It will go faster because your heart will pump hard so you can run faster. – Isabel M
Our heart will go faster because we are doing more movements – Freya
It will beat faster because we are out of breathe. – Joshua
It will go fast because the rest of us is going fast. – Jenna
The heart will beat faster after excersise

Then we experimented:

We found that our heart rate prediction was correct, but our puff prediction was wrong.
