We have been experimenting and testing the force of water on objects by investigating things that float and sink.
To begin we collected a variety of items from around the classroom to investigate. As a class we predicted which items would sink and float in water. Next, in our groups, we took turns to test the items to see if they would sink or float. Lastly we sorted the items into two groups; sink or float and we recorded our results.
The second activity we completed was ‘Design a Boat’. Firstly we experimented with a ball of plasticine to see if it would sink or float and if changing its shape would make a difference. Then in our groups we tried to use the plasticine to design a boat that would float. If we were successful we tested our boat to see how many ‘passengers’ (dried peas) it could carry. After a few attempts some groups were successful! 🙂
The last activity we completed was an experiment called ‘Dancing Raisins’. We predicted what would happen to the raisins in water and in soda water and then observed the differences between the two types of water. We were amazed to watch the raisins begin to ‘dance’ in the soda water! Why do you think this happened?! 🙂
In room 10 we decided to experiment with energy and forces. We each made two paper helicopters using a simple template. What we need- Paper Helicopter Template. Scissors. Paper Clips. Ruler. With our paper helicopters made we then measured the length … Continue reading →
As part of the GreenWave Project we usually measure the windspeed. This year the GreenWave project is not running but we are still going to go ahead with the project. Check out instructions for how to make an anemometer by … Continue reading →
Investigation 1 What did we investigate? We wanted to find out which would fall to the ground first, a square piece of paper or a ball of paper? What predictions did we make? Because both the pieces of paper were … Continue reading →
We investigated forces in Room 12. First of all we discussed the difference between a push force and a pull force. We also discussed friction. Friction is a force that slows things down. We came up with examples of push, … Continue reading →
In room 12 we made our own hovercrafts. First of all we had to learn a little bit of information about the hovercraft. It is a vehicle that glides over sea or land on air. Although it is heavy, the … Continue reading →
Objectives: Understand that friction including air resistance is a force that slows moving objects and may prevent them from starting to move. Understand that when objects are pushed or pulled an opposing push or pull can be felt. Understand that … Continue reading →
