3. Construct a triangle out of: -Three toothpicks -Three DOTS candies STEM Module VCS April 24, 2012

4. Using your triangle, construct a Tetrahedron using DOTS candy and toothpicks. Tetrahedrons have four triangular faces, four vertices, and six edges. STEM Module VCS April 24, 2012

10. - Choose one of the ideas to build or complete. - Draw a final sketch of your project. - Make sure you label all the parts with materials you think you will use. STEM Module VCS April 24, 2012

13. Complete 3D Models 3-Dimensional Calculations: - Surface Area - Area - Volume STEM Module VCS April 24, 2012

14. Evaluate your solution. -Did you feel you had a design had the best representation of the build? -Would one of your other ideas have been better? -Why or why not? -What would you have done differently? -Could you add to it to make it better? - What would you add to it?
