InTerm 2 Pukeko Room (Rm11) looked at forces and motion.

To understand friction, we made balloon powered cars and then raced them on different surfaces. We conducted an experiment with toy race cars, timing what surface caused the car to go faster or slower. To understand gravity we made parachutes and put different weighted objects inside the cup. 

Here are some of our thoughts:

• Micah Greig: If the balloon (for the balloon car,) is too big, the car will go slower as the air released is slow.
  
• Luca Evans: Gravity pulls things towards to the earth, so we dont fall down to Antartica or fall off the world.
  
• Tavonga Muza: Less friction makes the balloon car go faster; more friction makes the car go slower.
  
• Joshua Dos Santos: The more friction the more the car goes slower. If you put the wheels too close to the base then it creates friction that slows down the balloon car.
  
• Alina Li: I learnt that if you blow just a little bit of air into the balloon ( for the balloon car) it will go a further distance.
  
• Elissa Piao: I learnt that when you rub things together it makes friction . Sometimes that makes carpet burns.
  
• Fadziso Madondo: Gravity makes things fall down unless you are in space.
  
• Caleb McKinnon: If you put wheels on objects that are are not circluar it wont work, it will be very bumpy.
  
• Jane Wu: I learnt that gravity keeps us onto earth so we wont fall into space.
  
• Caleb Crocker: Axles control wheels.
