These little science challenge bags would be great as party favour, class rewards, homework challenges or something to keep children busy if they finish their work early. You could fill them with an almost endless variety of inexpensive materials. I’ve put together a few ideas to start with and will keep adding more, so do pop back.
Science Challenge Bags
1. Write a secret message?
This bag contains white card and a selection of coloured crayons including white. The idea is that the children write a message using the white crayon and ask a friend to reveal the message by rubbing a different colour over it.
Build a tower wider at the top than the bottom.
3. Build a tower with straws and plasticine
This tower is a bit trickier to build than the cup tower. Children need to mould the plasticine into small balls and stick the straws into it to make a shape.
Make 3D shapes
4. Create a Skeleton
Create a skeleton using black card and ear buds.
Draw with chalk instead.
5. Static Electricity Balloon
The idea is that once the balloon is blown up, it can be rubbed on hair or a jumper and become charged with static electricity. If held near the tissue paper the paper will jump up and stick onto the balloon.
Try different types of paper and shapes, do they still stick to the balloon?
6. Density Bottle
The bottle contains coloured water and vegetable oil. The oil and water will always separate if the bottle is shaken as oil and water don’t mix.
Find small objects to float on each layer.
7. Pipe Cleaner Challenge
The idea here is that children construct a pipe cleaner figure that will stand up without support.
8. Make a Paper Spinner
The full instructions for making spinners are here. These are super simple and perfect for starting to think scientifically. Children can try making bigger and smaller spinners and add different amounts of weight to the bottom to see how that effects the speed of descent.
Can you think of any more challenges for us?
