From YouTube: Silly Science Experiments

Description

This week's #SummerReadingChallenge2020 theme is non-fiction with Merry the Giraffe. Our favourite activity to do during ANY reading challenge is to make slime. In this video, Lucy shows you how to do that and make exploding rockets too!

A

Hi everyone, I hope, you're having a lovely summer and you're enjoying taking part in the summer reading challenge this week, we've put a video together of some simple science experiments which you can do at home. They don't need too many different ingredients. They should be easy things for you to find, and hopefully you'll have some fun and getting involved with this silly science.

A

Okay, so for today's silly science experiments, we've got two different experiments for you to take part in and our first one is silly slime. So to make the silly slime, you will need some pva glue, some bicarbonate of soda, some gel food coloring and some eye wash or contact solution.

A

And when you buy the contact solution, you just need to make sure that in the list of ingredients it says boric acid, because that is the ingredient that we need to make the slime. Okay, let's get started, so you just need to have a bowl mixing bowl, and here is our glue. You want 100 milliliters of the pva glue that I've measured out in this jug, so we'll pour that in to our.

A

Bowl next we're going to add half a teaspoon of bicarbonate of soda.

A

Add that in to your bowl next you want your gel food coloring I've gone for green, but you can choose any color that you like and give that a good squirt into your bowl.

A

If you wanted to, you could also add some glitter at this point once you've got that in there we're going to give it a good mix.

A

A

You should have a bit of a gloopy mixture now we're going to use our contact solution.

A

So for this you just want a teaspoon measure, we're going to put one teaspoon of the contact solution into our blue mixture and give that a mix around you should start to feel it's a bit more sticky and stringy.

A

Okay, once you've mixed that in we're going to add one more teaspoon of our mixture.

A

It should start to really loose together now.

A

You'll find it's harder to stir and it gets a bit thicker and starts a little bit like this now at this stage, it's time to get a little bit messy because you need to get your hands in there.

A

So you want to get your slime out onto your surface, so you might want to put down a tablecloth or a plain axe that you can use and you want to kind of knead your slime and play with it. So it gets less sticky and you do this by just rubbing it round in your hands.

A

So, as I said, you could do this any color, you like you, can add glitter into it to make it sparkly. You can add two different colors and see what happens.

A

You can even make unicorn slime, so you could make unicorn slime, maybe one pink dose of slime and one purple and then mix it all together.

A

But after a few seconds of just mixing in your hands, you'll notice, it starts to get a little bit less gloopy and more slimy. So you end up with some lovely silly slime just like this, and you can do lots of fun things with it.

A

So maybe try using some plastic knives chopping it up into different pieces, put it into some molds and see what shapes you can make and if you want to keep it just make sure you put it into a plastic pot with a lid, and it should keep for you for a few days and for you to play with have a great time and we'd love to see some pictures of the slime that you make so for our next experiment, we're going to be making exploding rockets and for this one you will need some fizzy vitamin tablets which look like this in a tube, and this is what they look like outside of the tube and you'll need some warm water and because we're making a rocket, you can decorate your tube if you'd like to and you could make fins for the side.

A

You could wrap it in colourful paper. You can even put some streamers on it. If you wanted now for this experiment, you do need quite a lot of space so to launch our rockets we're going to head outside. So you will need your tube. You may have decorated, it ready to be a rocket, and you need to take out the lid which looks a bit like this.

A

Take one of your fizzy tablets and you're going to pop it into the holder a bit like that now you're going to fill your tube about a third full with your warm water and then you're going to stick your lid back into your tube. And then you want to put it on a flat surface, we're using a tray so that you can get ready to launch.

A

So the science behind this experiment is all about a build up of gas inside the tube. So when your fizzy tablet mixes with the water, it releases carbon dioxide and as that fills up the tube, it creates pressure and that's why the rocket explodes off. So let's try this one again. I'll fill up our tube with a bit more water.

So just remember, when you're doing any kind of science experiments to keep yourself and the things around you safe, so try wearing something to protect your clothes. It could be an apron, an old shirt, an art shirt that you might have at school and protect the furniture. That's around you, so you might want to use a wiper ball table mat newspaper or some kind of plastic sheeting to keep everything safe.

A

Remember when you're, making the slime once you've made it and you've had fun playing with it, make sure you wash your hands after your playtime and also try not to get it on any kind of carpet or clothing. It will wash off, but it might make a little bit of a mess hope you have fun.
