There are so many more STEM homemade toys you can create:-
To create this Marble Run all you need:-
Foam pipe insulation (20mm)
Silver duct tape
Cut the foam tubes in half and tape end to end, so you have a long run of tubing.
Masking tape one end of the tubing to something high like a table or door handle.
Have an experimental marble roll to see what happens.
Next, experiment with creating a hill by placing an object under the tubing. Try another roll. What happens if you move the hill or make it taller?
Now add a second hill. Again, explore what happens when you change heights and positions of the hills.
Finally, use wrapping paper or toilet rolls to create tunnels around the tubes.
To create Magnetic Slime all you need is:-
Magnetic powder (iron filings)
Liquid laundry detergent (check it is Borax-free)
Place glue in a bowl, stir in 3tsp of magnetic powder. Add a small amount of laundry detergent and stir in to form slime. Keep adding and stirring until you reach the desired texture (feel free to use your hands to mix).
Then, simply use as normal and for an extra fun twist put your magnet close by and see how the slime reacts!
To create this kaleidoscope all you will need is:-
Toilet paper roll
First, decorate the outside of your toilet paper roll. Leave to dry, if required.
Cut your mirror card: it should be the length of your toilet roll and 11.5 cm wide. Fold into three x 3.5cm strips with a 1cm excess (it may help to measure and score it first).
Roll into a triangular tube, tape in place and slide into the toilet roll.
Cut the top off the straw, including the bendy section. Tape the piece with the bendy section to one end of your toilet roll, with the bendy part hanging over the end of the roll.
Trace a 5cm diameter circle onto your cardstock.
Use a sharp pencil to poke a small hole in the middle of the circle. Decorate your circle (perhaps with wrapping paper?)
Push the bendy end of the straw through the hole in your circle (the decoration should face towards the roll). The ridges on the bendy part of the straw should hold the circle in place.
Look inside and spin for patterns!
All you need to make Icosahedron Bauble:-
Printer, compass or round object
Coloured paper (10 sheets)
Glue stick or double sided tape
If you have a printer, print out the template PDF. If you don’t have a printer, use a compass or round object to draw out 20 circles. Cut out our circles. They don’t have to be perfect, just try to make sure they all end up roughly the same size.
Fold the circles into equilateral triangles – if you’ve printed out the template just follow the lines.
Stick five of the triangles together in a circle using the flaps. Arrange them first so you can see how they fit together.
Repeat this process, creating another circle from five triangles.
Take the remaining 10 triangles and arrange them in an alternating pattern (one facing up, one facing down) so they form a long strip. Stick them together.
Once the strip is complete, attach the first flap to the last flap to create a ring.
Attach one of the circles to the bottom of your triangle ring by matching up the flaps and sticking them in place. You will now have a bowl shape.
Finally, attach your remaining circle to the top of your bowl (this bit is quite tricky), again matching up and attaching the flaps.
Now you have your finished Icosahedron bauble just add the ribbon!
What you will need to make your dissolving egg:-
Small toy e.g. plastic dinosaur
180g baking soda
Add glitter to baking soda, mix thoroughly.
Add 2 tbsp of citric acid, then 1 tsp of oil and mix well. This should make a dry and crumbly dough that sticks together if you press it. If it won’t stick, then add more oil a tiny bit at a time.
Press the mixture around your small toy until you have formed a good sized egg. Set aside to dry overnight (at least 10 hours).
When you are ready to hatch the eggs, simply place in a tray or bathtub and add water!
When the baking soda and citric acid hit the water, they react and create Carbon Dioxide bubbles. This causes the fizzing and the disappearance of the egg.
None of the ingredients in this egg should be consumed.
What you will need to make your Bouncy Balls:-
Access to a tap
A packet of party balloons (15-30 balloons per ball)
Two sets of hands!
Carefully fill the balloon with water until it fits neatly in the palm of your hand.
Standing over the sink, pinch the neck of the balloon, and then tie a knot. Make sure there isn’t any air in the balloon before you tie.
Trim the neck of the balloon. Be careful to leave a little room above the knot so it doesn’t come undone later.
Cut the neck off the rest of your balloons.
Stretch each balloon and put the water filled balloon inside, then stretch out what is left of the neck and cut it so that where it snaps back there is no neck left. You may need help with this, it can be tricky!
Repeat this process until you have made at least 15 layers. For a really bouncy ball use 30 layers.
To ensure an even shape, turn the ball each time you wrap a balloon around it, so that it doesn’t have any weak points.
What you need to make your very own Balloon Boat:-
Extra thick kitchen sponge
Wide plastic tubing
Small rubber band
Felt tip pen
Tub or container to test
Draw two diagonal lines to create an equal sided point at one end of the sponge. This will be the front of your boat. Once you are happy that the shape is even, cut it out.
Cut a small slit at the centre of the boat. Blow your balloon up and let the air out to stretch it.
Poke the neck of the balloon through the slit in the sponge. Stretch the neck of the balloon around the plastic tubing. You may need to secure it with a rubber band if it’s a bit loose.
Get your water container ready.
Inflate the balloon by blowing through the tube. Put your thumb over the end of the tube to stop air escaping.
Put the boat into the water, making sure the tube is pointing to the end of the boat.
Take your thumb off the tube and watch your boat go!
As well as trying The Smartphone Projector we also tried the Living Gingerbread House!
Living Gingerbread House
What you need to make your very own Living Gingerbread House!
Four plain sponges
Glue gun or craft glue (optional)
Spray bottle (clean)
Choose a sponge to be your base. Choose two more sponges to be the walls.
Cut one sponge in half across the longest side (i.e. make two regular rectangles, not two long strips) and set aside.
Cut your second sponge in the same way, and then cut the halves in half again (also across the longer side). You will only need two of these pieces, so set two aside.
Cut your last sponge in half in the same way as the others. These will be your roof.
Put your base sponge onto the plate. Work out how you will assemble your walls before you attach them: you should have two large rectangles and two smaller rectangles, all of the same height. Arrange them into a box shape.
Insert cocktail sticks into the sides and bottom of your sponge walls, so that about half an inch of the stick is still visible. Push the sponge walls down onto the sponge base and into each other so they are secured in place by the cocktail sticks.
Attach the roof in the same way. Place your finished house onto the plate.
If your house is a bit wobbly, you can secure it using a glue gun or some craft glue.
In both cases, allow time for the glue to dry and set before you move on to the next stage.
Next, you need to cover the house with seeds. You can use mustard or cress but there are many fast sprouting seeds, so have fun and experiment!
First, dab some water onto the roof of your house. Put a tablespoon of seeds into a small dish and mix with a little water.
Spread the seeds onto the roof.
Pour a little water onto the plate so the sponge base can soak it up. Check the sponge is nice and moist. Then sprinkle the seeds onto the base.
Leave in a warm, bright spot for the seeds to germinate. Spray the house with water using a spray bottle each day, and pour a little water over the house if it feels dry. In a few days the seeds should start to sprout, in a week they should be well grown.
Instead of tooth picks, I let Jake loose with the ‘Super Sticky Glue’. Fair to say I think I think he did a great job. He followed the instructions but used the glue and he wanted the ‘front door’ to be sideways so it looks more like a garden gate. Jake then used Basil seeds as it is one of the herbs he likes to use when we cook our pasta sauce. We are just awaiting for the seeds to start sprouting.
Jakes Rain Catcher STEM Idea
After working hard on this I then let him choose to create anything he wanted out of recycle waste. He chose a bottle and yoghurt pots. He sellotaped the yoghurt pots onto the large bottle, and told me his invention is a ‘rain catcher’ and that he would like to see the rain he catches, turn to ice! Well that is surely possible as it has been in the minus degrees figures most of last week!
So his bottle is now in the garden currently in a plant pot to support as it kept falling.
What do you think of the STEM toys Jake made?
