Newtons three laws of motion

This week in class we have been learning about newton's three laws of motion and how it can impact our everyday lives. We did two experiments to experience some of the laws in full action!

Our first experiment required one cup and a thin piece of cardboard and a coin. We Placed the cardboard on top of the cup and the coin on top of that you quickly pull the cardboard towards you then the coin will stay in place and eventually drop into the cup. This happens because Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

Our second experiment involved a balloon, straw, thin string, and a piece of sticky tape. You had to blow up the balloon, then put your string into the straw then tape it to the ballon get someone to hold the other end of the string and then let go of the ballon. This will send the balloon zooming across the string until there is no air left in the balloon this happens because for every action there is an equal and opposite reaction the air flying out of the ballon gives another reaction making the balloon fly in the opposite direction


  1. Kia ora David - I can see that you got fully involved in our experiments last Friday to test two of Newton's Laws of Motion - we will take a break this week on Inquiry due to the Year 8 camp but looking forward to more science in Week 5!

  2. Kia ora David. I hope you had a fine week at Year 8 camp. You did an excellent job of describing the two experiments you did earlier in May. I have done those same experiments with students and future teachers in the USA. I look forward to reading about more things you do in science.

    1. thanks for your great comment i look forward to seeing more in the future :)
