PHYSICAL CHANGE vs CHEMICAL CHANGE

In Science 3, we have been learning about physical and chemical changes.

We did an experiment and we classified each one.

First, we start with a mixture...

Then, we mix...

Secondly, we put water and salt in a paper plate and we put a nail on. 

After waiting some days, the nail has changed due to the oxidation process.

We also mixed vinegar and baking soda.

 Another change we observed was a candle which changes from solid to liquid state when we set fire to it.

The same happened with an ice cube...

Finally, we put water in a bag and after a day it had started to evaporate.

The last one was the apple's experiment. We cut an apple and we saw how its color changed in a while, following the oxidation process.

OUR CLASSIFICATION WAS THE FOLLOWING ONE:

We are still waiting to see the changes in the experiment with bread...
