Bath bombs

We are learning to make bath bombs.
I enjoyed it when we put the water in and it exploded.
I found it challenging to put the bath bomb mixture into the cup.

Have you ever wondered how to make bath bombs?
First, get a clear bowl and add 1 cup of baking soda, half a cup of citric acid, half a cup of epsom salts, 3 quarters of a cup of corn starch, 1 teaspoon of vanilla extract add 30 drops of essential oils with a pipette.Stir it up then let it dry overnight. After its dried, you can put it in water and watch it explode.The reaction from the baking soda, citric acid and the water caused a chemical reaction and made it fizz up with carbon dioxide.

A.S.M Airport

We are learning to make Science Fair Projects.

I enjoyed making all the electronics.
What i found challenging was that when we tried to power it by a lemon it didn't work, it only sparked.

Yeast bubbles

We are learning to make Yeast Bubbles. I liked how the bubbles overflowed. I found it challenging to wait for the yeast bubbles to expand.
Yeast Bubbles
Have you ever wondered how to make yeast bubbles?
First, get a cup and put half a teaspoon of yeast in it then some warm water (37 degrees) and lastly 2 teaspoons of sugar in it.
Wait about 10 minutes and there will be yeast bubbles.
The bubbles happened because yeast likes sugar and it basically ATE the sugar which made it expand with carbon dioxide.

Filtering raro in sand and iron filings

We are learning about chemical reactions in class. I liked how the iron filings stuck to the magnet. It was satisfying. I found it tricky to use technical language. Here is my explanation.

Have you ever wondered how to filter things? All you really need is filter paper or a Magnet.

A mixture is two substances that don’t chemically combine, which means they can be separated.

If you put iron filings in sand, raro and water you can remove the iron filings with a Magnet. To remove the sand and raro, get filter paper and put in a cup. Next, put sand and raro mix in the filter paper and then put sand in separate cup and let it dry then put it in the Sand Pit. then with the raro put it in the sun and let the water evaporate.
