###
Communication in Space

Students will work in cooperative groups to create an accurate arrangement of mirrors that work together to relay a laser beam from a Mars space station to Earth’s Mission Control, which will model utilizing satellites in space for communication, an accommodation necessary for manned space exploration.

###
Modeling and Solving Two-Step Equations

Students will use various materials to create models of two-step equations. Then, they will take an equation, create their own model, and solve for the variable from the model.
