Following on from our fun Santa STEM challenges we’ve now got some easy Elf STEM Challenges.
Santa asked the cheeky elves to decorate his special tree, but they can’t reach the top, can you build something to help them?
A lolly stick catapult would work nicely for this, or a ladder made from paper or straws. If you make the ladder try to think how to test how strong it is.
One little elf is stuck on his shelf, can you build him a zip wire to get down?
The elf would like to slide down the zip wire very quickly, so think about the best type of string or rope to use. Remember there’s less friction if you use a smooth string.
What type of harness will you build for your elf? Would a candy cane work?
Can you time how long it takes the elf to reach the bottom? Do you think the time will change if you make the elf heavier?
Santa’s sleigh is very full and almost at it’s weight limit. Can you work out how many marshmallows or candy canes weigh the same as your elf?
If you don’t have scales or a balance can you build a coat hanger balance?
It’s Christmas Day and the elves want to play some party games, but the toy workshop is empty. Can you make them some bowling pins to play with?
Think about what you could use to make bowling pins, plastic bottles might be a good idea. Do you need to add some sand or water to make them more stable? What kind of ball would work the best?
Oh no! It’s raining and Santa’s sleigh doesn’t have a roof! Can you design a special cover for Santa’s sleigh that will keep the presents dry?
Think about the type of material you need to use? How could you test how waterproof it is?
One cheeky elf needs to get back to his shelf, can you design a hook that will help him reach it? The hook must be able to grip the shelf and hold the weight of the elf.
What materials would work well for this? You could try candy canes, pipe cleaners or maybe some velcro?
This cheeky is refilling an advent calendar using his hook.
Oh no, one little elf has lost his jingle bells, can you make him a noise maker so Santa doesn’t notice?
An easy way to make a noise maker is to put small items into a cup or tin can and cover with a balloon with the end chopped off.
What type of item do you think will make a good jingly noise? Which is better a cup or can?
