Day 6: Density of Liquids

Classwork: Today the students continued to learn about physical and chemical properties. The students discussed the density of fluids.

1. The students observed how mixing two liquids can result in the liquids separating by density.

2. The teacher shows the students one way to measure the density of a liquid, using a hydrometer.

3. As a class, the students calculated the density of water and determined the percent error.

4. Next, each lab team calculated the density of an assigned (non-water) liquid and predicted what order the liquids would settle into when placed in the same container. The students then calculated their percent error.

5. Finally, the class discussed how gases also have different densities and can separate by density. The students observed several demonstrations to illustrate this concept.

Homework:

1. Properties of Matter Quiz.

2. Complete "Density 4 HW" including the "Hydrometer Home Experiment"
