The purpose of this experiment is to learn how to identify a substance as a pure substance or a mixture, in addition to learning how to make various types of mixtures.

Making Molecules8.doc
The purpose of this experiment is to learn how atoms join together, to learn how to make molecules and learn how to write a simple chemical formula.

Measuring Mass8.doc
The purpose of this experiment is to learn how to measure the mass of various objects with a centigram balance

Measuring Temperature8.doc
The purpose of this investigation is to learn to take temperature measurements with a thermometer and find how the temperature of a mixture is affected by the amounts of hot and cold water used to make the mixture.

Measuring Volume8.doc
The purpose of this experiment is to learn how to measure the volume of various objects by direct and indirect measurements, using a graduated cylinder.

Observe.Chem.Changes8.doc
The purpose of this experiment is to observe a chemical reaction and record the evidence for any chemical changes observed. Making Molecules.doc The purpose of this experiment is to learn how atoms join together, to learn how to make molecules and learn how to write a simple chemical formula.
