###
Solving Equations and Inequalities

Students will be divided into four groups and work on their assigned task to become an expert. They will match vocabulary terms with definitions and examples, use the “Pass the Pen” strategy to create and solve equations or inequalities, or write a real-world problem for an equation given. The experts will then teach these concepts to their peers.

###
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.

###
Prokaryotic and Eukaryotic Cells

Students will categorize cells as prokaryotic or eukaryotic by identifying the presence or lack of a nucleus.

###
Lights, Camera, Action!

Students compare and contrast potential and kinetic energy by creating a real-world model through a movie.

###
Does it have Potential?

Students will work with partners to investigate how mass, potential energy, and kinetic energy act on objects dropped from varying heights.

###
Perfectly Proportional Percents

Students will collaborate to explain verbally how to solve percent proportions and scaling while showing their thinking.

###
Express Yourself

Students determine which expression is a truth or a lie by generating equivalent expressions.

###
Keep Your Balance!

**Students are introduced to solving one-variable, one-step equations using addition and subtraction through models and hands-on activities. The students will learn the substitution method of checking answers.**

###
Perfecting Percents

Students will engage in an activity that allows them to explore the different parts of percents: part, whole, and percent, and develop conceptual understanding of percents through the Concrete, Representational, Abstract (CRA) method of instruction.

###
Roll With It

Students will experience a hands-on lesson regarding ratios. While doing this, students will deepen their understanding of the concepts of ratios.

###
Got Force?

Students use various surfaces and a weighted car to see how far the car will travel using balanced and unbalanced forces.

###
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.

###
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.
