Last term we completed a unit on Push and Pull and Forces. I’ve never had so much fun in a classroom as I attempted to do an experiment every week – the kids very much appreciated it!
We discussed friction and created a definition. Then students selected different surfaces to test and in small groups, tested friction with toy cars.
We explored the power of wind – how it has the power to push and pull. Students then constructed little wind race tracks to test other people in the class. Using a straw, students used wind power (by blowing air) to push a Malteser through the different tracks. The absolutely loved it!
Tea Bag Rockets
A kid favourite!!!! Empty a simple tea bag, stand it on its end, then light the top. The fire will travel down the bag till the very bottom. At that point all the hot air, thats been pushed down the bag cylinder pushes the ashes up into the air – entertaining the kids to no end!!! Gravity then brings the ashes back down. We probably did this experiment 5 times, the kids were obsessed!
Pom Pom Poppers
Students loved this one. Use Pom Poms Poppers to create anarchy in the classroom. Explore the force of pull and how tension can produce a push. Google it for further instruction on how to make them – it is well worth it!
In groups of 4, kids made different paper airplanes. Templates and different designs were provided so that each member could make a different kind. We discussed the effects of wind, gravity and thrust (in paper airplanes, our muscles pushing the plane).
Every week the kids looked forward to what experiment we were going to complete. It took me a little while to find a good range of experiments to do during the unit, which suited Push and Pull or Forces. Here’s hoping this little run down helps someone else!
