Welcome Scientists. I hope you are all keeping safe and well. My plan is to find you lots of fun science activities to keep you busy. If you have any ideas, please do email them in to me (Mrs R-J) and I will share them on this page. I'd love to see your photos too. Lets have some fun.
Keep scrolling down to find new projects.
Why not take the "Save the egg" challenge from Science Sparks.
Build a vehicle designed to save an egg in a collision. They have used K'nex, but you could use LEGO or even wrap the egg in different materials and drop it from a height.
Boiled egg (it's less messy!)
K'nex/lego/other construction materials
test track area
Instructions for crash test: Design a car to hold the egg so it doesn't crack on impact with a solid object.
Think about how to protect the egg.
Can you think of anything else? Would changing the type of size of wheel help?
Crash test eggs extension ideas:
Try a different method of protecting the egg and design a test to investigate which method of protecting the eggs works the best.
Does your solution still work if you release the car down a ramp?
How can you make your comparisons a fair test?
Don't forget to send us your photos!
Can you build a tower of toothpicks to support a chocolate egg?
What you will need:
Toothpicks or cocktail sticks (You could always use spaghetti or straws too)
There’s no instructions for this one, apart from the building a structure that:
Stands up with no extra support.
Only uses the materials above.
Can hold the a chocolate egg without falling over.
These are the structures my children built, what do you think?
Shapes are a good thing to think about when building toothpick structures like this.
Triangles, arches and domes are all strong shapes and are used by engineers to make structures strong. Next time you see a bridge count how many different shapes you can see.
Imagine a square made from straws, if you push down it with fold down on itself, but a triangle won’t collapse unless one of its sides break. Any force applied to a triangle is evenly distributed from the vertex to the base, this means triangles are much stronger than squares.
Can you build a tower that is at least 10cm high? Or 20 cm high?
How about a tower that can hold 3 chocolate eggs?
Can you build the chicks a new house?
What else could you use to join the toothpicks together?
An old favourite of mine is Lemon Volcanoes:
You will need:
red food colouring
washing up liquid
Cut the top and bottom of your lemon off (ask an adult to help you with this!) so that you have a stable lemon that won't roll away! Using a craft stick mash the inside of the lemon to a pulp bringing out the juices. Place a few drops of food colouring into the centre of the lemon. Add a good squeeze of washing up liquid. Add a spoonful of baking soda to the lemon. It should start to fizz. To keep the reaction going keep adding lemon juice and baking soda to your lemon.
You can do this in a jar too if you haven't got a lemon to hand. You could use vinegar instead of lemon juice.
What happens if you don't use washing up liquid? Can you predict what might happen before trying it? What if you extra colours to your volcano, what effect will this have?
How to grow a cress caterpillar.
What you will need:
Don't forget to send us your pictures and thoughts.
Why not have a go at building a marble run......
You will need:
Tape – you can use masking tape, but anything will work.
Cardboard tubes – kitchen roll, toilet roll etc all work well.
Other bits of recycled packaging – boxes, bottles etc – optional
Egg cartons – optional
Large box or sheet of card to build it against
Marble or table tennis ball
The best thing about building this STEM Project is that you can be as creative as you like.
If you don’t have a big box to build it inside, you could also build them by attaching tubes to a wall, just make sure you ask a parent first and use masking tape so it doesn’t rip the paint off!
