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

In Science we are learning about change. Change happens when we mix or combine two different reactants (Substances together). When this happens a chemical reaction takes place.
