Basic Understanding of Geometry in real world situations (#4)Work with Special Right Triangles to solve meaningful problems (c3)Volume and Planar Density(e.1A-D)





Laying the Groundwork: First week

“What I did with Math this Summer” - A math-centered way to introduce themselves - Help them see that math is all around them - Use Design & Technology to present - Give me an opportunity to introduce Thin Films




After finishing Trigonometry and Pythagorean Theorem (mid September), we are going to have the first of three thin-film days.

Prior to the activity, students will receive a Pre-test on Thin Films and Engineering.




1. Thin films are found in all but what industry?

ComputerEnergyAutomotiveMedicalThin film is used in all these industries (none of the above)

2. Superconductivity means:Electricity moves fasterElectricity moves without resistanceElectricity causes sound waves as it movesElectricity gains strength as it is transmitted




Students groups will be asked to design a method for the most compact means of packing a box with ping-pong balls.

- connection to density



Other Lesson PlansCircle Unit: Planar Density. Deciding Fracture points.

Do structures break at the densestpoints or where they are least dense?(Silicon Wafers or Board breaking)Volume Unit: Build models of the three basic Cube structures. Decide which model is densest and provide accurate calculations. When is porosity

desirable? What can you tell me about the structure of a glass bowl versus the structure of a clay bowl?
