Race a Speedboat
Can you make a paper boat race across the water just by gently touching the surface of the water?
Hypothesis (What I think will happen)That it would glide across the water and speed fast.
Coloured card, washing up liquid, pencil or sharpie, scissors, large container of water.
Method (What we did)We put the paper on the water and got liquid on our finger.
Observation (What happened) Put the liquid in and it would of pushed the speedboat then it will go across the water fast.
Conclusion (Why I think it happened) Cause the liquid was inside is pushing the paper speedboat.
Short Experiment to Follow Up
Make Metal Float
Gently place a paperclip on the water’s surface.
Hypothesis (What I think will happen) that it would float slowly.
Observation (What happened)We put the metal paper clip down slowly with our finger and it just floated.
Conclusion (Why I think it happened)That the air was pushing it up and floating slowly through.
