Science Change

For this term for Science, we have been doing experiments and hypothesis. We
also have been writing and taking notes of what we do like for the Elephant
Toothpaste, the Vinegar+Baking Soda experiment. We had to write the
reactions of the experiments. We also have learnt what reactant/s, substance,
product, and Chemical Reaction means.

Substance: Is the materials you need to make a product.

Product: Is the thing that you made with the substance and reactants.

Reactant/s: Two reactants can make a product

Chemical Reactions: The reaction that the chemicals (substances) makes.

Example: Ice melting to water. If a physical change occurs, the physical
properties of a substance will change.

Science-Change

Today for Science, we did an experiment and we had to make a hypothesis (guess) what will happen if you put 1/3 part of vinegar in a bottle, and put 2 tablespoons of baking soda, then cover it up quickly with a cork. And this is my answer.

What do you think will happen? It will foam up and will fizz. Then the cork will fly away.

	What do you think these will be?
Reactants	Vinegar, Baking Soda, bottle
Product	Turns to gas (carbon dioxide)
Chemical Reaction	It’s going to form foam and will fizz, and the cork will fly away.

Was your hypothesis right/ wrong? Why? Yes because the cork popped when the foam reached it.
