Week 9

End of Unit 1

CLASS 1: Cambridge Mock Test

Today we will solve one the mock tests to practice for the checkpoint exam you will have in eight grade.

This simulation includes topics you have learnt in previous years, but we are going to have 20 minutes to review some of those topics. Feel free to study the ones you feel you have more weaknesses in, so you have a better idea during the test:

Metals and non-metals
Digestive system
Circulatory system
Sound waves (Pitch and loudness)
Magnets and their poles
Chemical symbols
Human reproduction process

Today we finish our first unit of the year: reactions are fun. This is why we will solve an activity that allows us to summarize some of the essential compounds we studied during the reactions topic.

According to the Collins dictionary, "inorganic" means <<Not having the characteristics of living organisms, not organic or not made mainly of carbon atoms>>. This word is used to describe compounds that are not the base for living things, but that are very useful in our daily lives.
