###
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.

###
Newton's Second Law

Students will work in partners to investigate Newton’s second law by testing a series of experiments with varying conditions.

###
Equations in the Real World

**Students will create and solve equations with variables on one side before comparing the equation with another to determine at what rate they will be equal. **

###
How Newton's Laws Apply Every Day

Students collaboratively determine how the characteristics of a real-world job correlate with each of Newton’s Laws and why that is relevant to their own lives.

###
Rise Over Run! Let’s Have Fun!

Students will collaboratively practice identifying and graphing slope and y-intercept.

###
Finding Clues to Solve Equations and Inequalities

**Students will solve one variable two-step equations and inequalities using a variety of materials while working independently and collaboratively in learning stations.**

###
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.

Volume of Triangular Prisms

Students will use hands-on manipulatives to discover the connection between the shape of the base and the height to determine the volume of a prism.

###
Convergent Plate Boundaries

Students will design and test models that will identify crustal features formed by convergent plate boundaries.

###
Full Speed Ahead

Students will use hover pucks to measure speed over a distance of six meters. Once speed has been calculated, students will determine velocity using the same data. Finally, students will be able to label all points of acceleration.

###
Building a Watershed

Students will model the effects of human activity on watersheds.

###
Modeling the Path of Digestion

Students model the path of digestion using household items.

###
Diagramming Dinosaurs

Students will use a verbal representation to explore a constant rate of change in the size of dinosaurs over a period of time and represent their data by graphing.

###
Compound Probability: Independent vs. Dependent Events

Students will review steps for solving compound probability problems through an activity involving doughnuts. Students will then determine the difference between independent and dependent events through compound probability task cards. To encourage students to work through their struggle, students will rate themselves on a scale measuring effort and achievement at the end of the lesson.
