CHEMISTRY…

IS THIS WHAT YOU THINK?

Slide 2

Chemistry is Life!

And who are the chemists?

Slide 3

My Vision

-Too often kids get to high school chemistry and they are scared before they even begin.

-My goal is to shape a positive image in their minds about chemistry so that they can be more prepared mentally for high school.

-I will do this by showing them how applicable chemistry is to every day life. It is the study of everything, and it is the central science.

Precipitation Reactions

Precipitation reactions: When an insoluble solid called a precipitate forms when reactants are formed together.

For example, when Carbon Dioxide is mixed with Calcium Hydroxide (limewater), the precipitate Calcium carbonate is formed.

Ca(OH)2+CO2→H2O+CaC03
