This is a great themed activity for starting to learn about properties of materials and good experimental design.
First we made 3 different pirate swords. You could use any materials you want, but we used thin cardboard, a cardboard tube and a balloon
Hold the swords, which do you think will be the strongest? Can you make a hypothesis?
Decide how to test your swords ( be careful ) what do you need to keep constant in your testing?
We decided to bang the swords on an empty cardboard box and observe the changes in the swords.
Variables to keep constant
Person holding the sword
Force used to hit the empty box
What do you notice? Was your hypothesis correct?
We found the cardboard tube made the best sword from a strength point of view, it didn’t bend or break like the other two.
However, we also concluded that the balloon made the best pretend play sword as it didn’t break on impact, but also wouldn’t hurt anyone else.
Can you think of any other materials we could’ve used?
Video of how to make a balloon sword coming soon!
Suitable for Early Learning Goal 16
Exploring and using media and materials
They safely use and explore a variety of materials, tools and techniques, experimenting with colour, design, texture, form and function.
