To sum up the past couple of weeks. The classes have been focused on Section 4 which is about a few basic physical properties of matter. Properties such as strength, elasticity, malleability, and bounce were studied during the creation and testing of a Play-Doh like substance during lab. This introduced the concepts of composites when an additional material was added to see how the properties of the "Doh" changed.
Section 5 is focused on the property of density, another physical property. Density is the ratio of a substances mass to its volume. The lab work challenged the students to make mass and volume measurements of liquids and irregular solids. This introduced the students to the techniques of massing by difference and water displacement. Lastly we will be practicing our problem solving skills using density.
The goal for the week would be to wrap up these concepts for a quiz at the end of the week.
