2. Conservation Theme Conservation of MatterConservation of Matter Conservation of EnergyConservation of Energy Conservation of MomentumConservation of Momentum

3. Rationale Important to All Science Disciplines Difficult for Students to Understand and Appreciate Lends Itself to Modeling and Simulations Incorporates and Reinforces Math at a Variety of Levels Flexible – Can Spiral Through Levels

4. Intended Topics Energy and Momentum in Classical Mechanics Matter and Energy in Food Webs Matter and Energy in Atmospheric Chemistry

5. Energy and Momentum in Classical Mechanics The students will develop and/or use multiple models to illustrate and simulate conservation of energy and momentum in standard High School Physics topics. Tools: Stella and Excel

6. Matter and Energy in Food Webs Student development of a simple model and modification of existing simulations to show recycling of matter and transformation of energy in a simple ecosystem or food chain. Tools: Stella and possible multimedia

7. Conservation of Matter and Energy Atmospheric Ozone A student developed simulation to determine the importance of ozone in the stratosphere and the effect of various substances used by people on its concentration. Tools: Stella and possible multimedia

8. Examples from this Week Next two slides show similar output for projectile motion using Excel & Stella. Key teaching questions include whether either model is student or teacher created and which one is conceptually easier to build, understand, and use.
