Fizz & Foam

Fizz & Foam

1 I put some vinegar in a container

2 I put 2 teaspoons of baking soda into the container

What happened? 

The baking soda and vinegar mixed together and made a gas which made a foam that kept rising higher and higher. They turned from solid and liquid into gas. I tasted it and my Mum said it would taste like coke but it taste disgusting.

Billowing balloons

Hi bloggers, This is my science experiment.

Billowing Balloons

1 I put some vinegar in a bottle

2 I rolled the paper like a cone and put the balloon over the end

3 I put 2 teaspoons of baking soda into the balloon

4 I took the cone away and put the balloon over the top of the bottle

5 I lifted up the balloon and the baking soda mixed in with the vinegar

What happened? 

The baking soda and vinegar mixed together and made a gas which filled up the balloon. They turned from solid and liquid into gas.

The gas was produced with such force that my balloon blew off the top of the bottle and the gas was gone. So when I put the balloon back on, it only filled up a little bit.

Next time, I will hold on to the balloon so it doesn't fly off the bottle.

Lava Lamp

Hi bloggers,

This is my post about my science. I did a Lava Lamp. It was a chemical change. The disprin tablet changed from a solid into carbon dioxide gas. When the gas went through the water and baby oil it made bubbles and blobs. The baby oil sat on top of the water because water is more dense than baby oil. You should try this experiment at home.

Chocolate mug cake-science

Hey bloggers,

Today I did a Science experiment about Chemical and Physical change.

The dry ingredients like cocoa, flour and salt were solid and then there was a Physical change and they became liquid because they were mixed with milk egg and melted butter.

I cooked the mixture in the microwave and the baking powder made the mixture rise up in the cup. This is a Chemical change.

I hope you like my photos. I liked the mug cake. It was filling. I did not think it was going to be sooooo filling.
