Density WebQuest Website



Additional Resources: Density Activities Hands-On Learning Density WebQuest 2

1. Students will read about density in the textbook. 2. Demonstrations will be provided: Brick Versus Styrofoam Block; Ping Pong Ball Versus Golf Ball 3. Review units with students and explain the density formulas. 4. Practice calculating density using the GUESS method. 5. WebQuest: Mass, Volume, & Density 6. Lab: Have You Lost Your Marbles? (Calculating & Graphing Density)
 * __C. Instruction Procedure/Activity Demo__**
 * Calculate the mass per unit of volume (ie density) to see the difference

Through various instructional strategies and reinforcement, students will develop the ability to calculate, interpret, and apply density concepts to real life experiences/situations. After learning the density formula and how to utilize this formula for problem solving, students can carry out a scientific experiment which requires them to collect, calculate, graph, and interpret data. With the use of reinforcement, students are able to practice the mathematical aspect of the concept and learn which units pertain to which aspect of the density calculation.
