Density
Learning Outcomes1. Determine the volume of regular solids using formulas and of irregular solids by displacement of water.
2. Calculate the density of various objects. 3. Use density to predict how objects will behave in a density column. 4. Design and conduct an experimental procedure to determine the approximate density of air. 5. Compare the relative thermal expansion of liquids and gases and its affects on density. ActivitiesPhysical PropertyCreate a bubble map about physical properties using pages 188 - 189 in the current textbook. Provide definitions and examples.

Draw 4 examples of physical change. Fold a piece of paper into 8 squares. In the first colume draw an object in each box. In the second colume draw the same object with a physical change. Section Review1. Complete the Section Review on page 193 in the current textbook.
2. Create an illustrated science dictionary. Include the word, the meaning of the word written in your own words, and a picture that illustrates the meaning of the word. The word entries will be: Physical Properties Density Matter Mass Volume Weight Bouyancy Physical Change |
VocabularyPhysical Property - A characteristic of a substance that does not involve a chemical change, such as density, color, or hardness.
Examples Thermal Conduction State Density Solubility Ductility Malleability Density – How closely packed together the molecules of a substance are. Physical Change - A change of matter from one form to another without a change in chemical properties. Bouyancy – Ability to float or rise to the top of a liquid or gas. Float – To sit near the surface of a liquid or gas, to not sink. Mass - How much matter fits in a given space. Matter - Stuff Weight - A measure of the force of gravity on an object. Materials with more density weigh more. Finding the Volume of an Irregular Objects
First, fill a graduated container with water and write down the volume of water. Second, place the irregular shaped solid in the water and measure the volume inside the container again. The difference between the two levels is the volume of the solid. Subtract the first number from the second number to find the volume. This does not work for objects that float in water. If an object floats in water, first measure the volume of a weight. Then place your object in the water with the weight on top. Subtract the volume of the weight to find the volume of the irregualr object. Why does the diet drink float and the regular coke sinks?
