Unit 7: Matter, materials and forces.

Hello everyone!

As you remember, this week we started reviewing some concepts and ideas to start with unit 7.

We talked about the universe, and we al agreed that it is made of matter, and we can find that matter that is in ALL THE UNIVERSE in three different states: solid, liquid and gas.

So, matter is neither created nor destroyed, it just changes from one state to another. Those changes can be reversible or irreversible, depending of wether the change can later return to the original state, or not.

We also agreed that matter can make up different materials, and that those different materials have different properties.

Now I'm going to provide you with complementary materials and resources with which you can review and expand your knowledge about the content of the unit. ENJOY!
