If you’re using Aliens LOVE Underpants as activity inspiration, this science investigation is great fun. The idea is to dip cutouts of underpants made from different materials into water and then time how long each material drips.
Children can be encouraged to think about the properties of materials that make them absorbent or waterproof and consider how to make the investigation a fair test.
Materials for Aliens LOVE Underpants Activity
String
Water
Sticks
Different types of paper and cloth
Stop Watch
Instructions
Construct a washing line using the string and sticks.
Cut out and decorate alien underpants using paper and material. To make this a fair test, all the underpants should be the same size.
Hang the underpants on your washing line.
Dip each pant into the water for 2 seconds, hang back up and time how long it takes to stop dripping.
Questions to ask
What do you think would happen if you made the pants bigger?
What would happen if you laminated the pants?
How could you make waterproof pants?
Why should all the pants be the same size?
How can you make the investigation a fair test?
Make it into a challenge!
Extension tasks
Can you record how long it takes for the pants to dry completely in the sunshine? How can you tell if something is dry?
Try one of my other science experiments linked to storybooks.
