Amalea's Static Electricity Experiment

One day I did a experiment about static electricity. Here is what I did:
I went on the computer and typed up what my experiment means and I also typed up what I was going to do.

What you need:

two balloons
hair
one can
wool

What you do:

rub the balloon against your hair
move the ballon around and watch how the hair attracts to the balloon!
rub a different balloon on wool
put the balloon close to a can and watch how the can follows the balloon!

This reaction happens because of positive and negative static electricity.

Chris' Dry Ice Bubble

My experiment was a dry ice bubble . Room 21 watched my experiment!!! It did not work the way it was supposed to work, but Room 21 still liked it. It looked like a bunch of clouds!!

When I put dry ice in water it made steam like Halloween fog!!!

Room21 took a photo of me holding a bubble.

You will need:

a bowl with a lip around it
dish washing liquid
and dry ice

When you do it, it looks like a clouds I hope you like it.

Kate's Lemon Fizzy Drink!

In room 21 we are doing experiments! My experiment was making Lemon Fizzy Drink! Here is what I did.

I squeezed a few 1/2 lemons into a glass
I put in the same amount of water as lemon juice
I added a teaspoon of baking soda in to the lemon juice and water

We watched the lemon juice fizz when I added the baking soda. A lot of it spilled out of the glass! Everyone in Room 21 got to have a little taste of the fizzy lemon juice! I thought it was WAY too fizzy! Some people thought it was too sour. Some people really liked it!

Do you think you could try this experiment at home? It is a lot of fun :)

Neela's Lava Lamp

One very exciting day I brought an experiment to show the class. It was a lava lamp! I was very excited about showing the class! We even showed Room 22 because they practiced theirs, but it didn't work.

These are the ingredients:

water
vegetable oil
food colouring
Berocca tablets, broken into quarters
and a funnel.

I poured the oil into the funnel.

After I had poured in all of the bottle of oil I waited for the water and oil to separate from each

other.

Then I put 12 drops of food colouring.

Then I added the berocca into it.

What do you think happened?
This is what it did - The Berocca bubbled and pushed the food colouring up into the oil in big blobs! It looked like a real Lava Lamp!

Ayaana's Tornado Time!

On Tuesday 30 October I made a Tornado In A Bottle! My mum thought Miss Williams shook it, because it was hard, but I did!
If you want to make a torndo at home all you need is glitter (that's not silver), some dish washing liquid and a clear drink bottle filled with water.Mix all that together. Screw the lid on. Turn it upside down and turn it around in circles.Watch carefully and see what happens.

Glowing Water by Baxter

On Wednesday I brought my experiment to school. My experiment was glowing water. If you want to do this you will need :

bottle of tonic water
ultra violet light

Instructions

Go into a dark room.
Get the ultra violet light and tonic water.
Turn the ultra violet light on.
Shine it on the tonic water.

It will glow!

Lokkie's Static Electricity

For my experiment, I made static electricity. This is how I made static electricity

You need:

balloon(you can use helium or normal)
cut up paper
hair

Rub the balloon on your hair. After that, put the balloon on the cut up paper then the paper will fly up just like this...!.

That is static electricity.This is how it makes static electricity.The cut up paper and balloon are both positive energies. If you rub the balloon on your hair makes the balloon negative. That's how it attracts the paper. You can try this at your home.
