Oliver's Vinegar Explosion in a Bag!

Today I showed my experiment. An experiment is a kind of magic trick. Like if you put one teaspoon of baking soda and vinegar into a Gladbag it will pop! My sister helped me to put Baking Soda and Vinegar into a bag and then we sealed the bag shut. The vinegar and baking soda make a reaction that makes them fizz. It started filling the bag with air and the bag got fatter and fatter. It was great. In the end the bag got too full of air and it popped. It was an exciting experiment!

Leticia's Vinegar and Baking Soda Volcano

On an exciting day, when my class was learning all about experiments, my teacher (Miss Williams) let all of us bring an experiment. I brought my experiment two days ago. It was a volcano (but not a real one). It is one that is made of vinegar and baking soda. This is how you make it:

You will need:

• An egg shell with a small hole on top
• Vinegar
• Baking Soda

Instructions:

1. Put 3 teaspoons of baking soda into the egg shell.
2. Pour the vinegar into the egg shell.
3. Stand back and watch what happens!

The vinegar and the baking soda make a reaction that creates bubbles and a thick foam comes erupting out of the eggshell. It is a cool experiment! All of the people in my class enjoyed watching the volcano erupting.

Floating Cardboard by Dhruv

On Tuesday it was my experiment day. My experiment was making cardboard float!

What You Need:

• A cup full of water (full to the very top!)
• Cardboard.

Instructions: 

• Fill the cup with  water
• Put the cardboard on top of  the cup of water
• Count to 10
• Turn the cup upside down, still holding the cardboard
• Count to 10 again
• Let go of the carboard
• The cardboard will stick to the cup and will float under the cup, even though nothing is holding it there!

Ryan's Paper Bridge

On Tuesday I did my experiment. Each child had to do an experiment. I made a paper bridge. To make a paper bridge you need two cups, a glue stick and paper. First you put the paper on the 2 cups, and then put the glue on the paper. It falls because the paper is not strong enough to hold a glue stick. But if you fold it back and forth like a fan and then put the glue on the paper it does not fall!! :p Folding the paper makes it much stronger and you can balance the glue stick on it!

Everyone enjoyed my experiment :)

Volcano in a balloon by Max

On Tuesday we were doing experiments.  My one was a volcano in a balloon.  First I put 3 teaspoons of  baking soda in a bottle then I tipped vinegar in the bottle. This made the vinegar bubble and turn to foam.  Then I put the balloon on top of the bottle and it filled up with foam!  Next Miss Williams tied the balloon up. After, we had a vinegar balloon! It was soft and squelchy - like a stress ball! 

I had fun doing a volcano in a balloon! I was happy that no one else did the same experiment as me. Now some people want to try it at home! Everyone got to hold it and squeeze it. I loved watching Chris' Dry Ice Experiment too. It was awesome! :)

Floating egg by Victoria

My experiment was called The Floating Egg. Eggs are usually heavy and sink to the bottom of the cup of water. If you do this experiment, the egg will float on the water instead!

Put water halfway in a glass.Then put 2 table spoons of salt. After, mix it with a spoon. Finally put the egg in - then it floats! I was proud of my self. Then we talked why the egg floats.The egg floats because salt makes the egg float because of something called buoyancy  Then I had to pack it up. I put the egg in a plastic bag. Then I put the salty water down the drain.

It was a fun experiment!

Morgan's Floating Orange

Hi! We are doing experiments in Room 21. My experiment was a floating and sinking orange. This is how you do the experiment. You need a container of water. Then you put an orange into the water. It floats!

Then peel the orange. Put it back in the water and this time it sinks! The skin on it makes it float. Did you know that?
