This line of curiosity and hypothesis started to grow questions in other students.
Violet asked, “How do things move?”
Travis asked, “Do electrons in atoms move at all?”
Te Pou stated,” Being stronger helps makes things move faster.”
Blake asked, “How do cars and planes move.”
We came up with so many wide-ranging scientific questions, we narrowed our exploration into exploring if we can change the distance covered by objects using a variety of movement principles.
We investigated tension and how the distance and number of connections between the blocks made it harder to exert force on the object.
We hypothesised that more rubber bands would make the pom poms fly further.
We set off to test our hypothesis with controlled tests.
Starting with one rubber band and a wooden framed slingshot that were all the same length, we set off testing and recording our observations. Increasing the number of rubber bands and recording the distance the pom-poms moved enabled us to make conclusions against our hypothesis. Being okay with challenging our first thoughts and using evidence to make our findings valid.
Next challenge: to build a catapult to discover what features will cause the catapult to fling the pom pom the furthest.
We started off discussing what we usually use to launch objects.
We made our hypothesis that bending the spoon back with one rubber band will send the pom pom the furthest.
Now we had to design our models to test our hypothesis. This was a great engineering project with a wide variety of designs.
