Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

In this activity, learners build a "pneumatic trough," a laboratory apparatus used for collecting pure gas samples over water.

In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.

In this math lesson, learners explore polynomial and rational function patterns.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

In this activity, learners explore density and buoyancy as they design and construct rafts.

Learners determine the surface area and volume of two identical boxes, and then figure out the dimensions of a cubical box with the same volume.

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

Learners design and create musical instruments from common objects; their challenge is to create an instrument that can make three different tones.

In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

Learners make a counting/estimating jar to exchange with friends or bring home.

In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

Learners act as engineers and design mini submarines that move in the water like real submarines.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners will put a set of containers in order by capacity. Would the tallest container hold more or less water than the wide, short one?

In this activity, learners explore Charles' Law in a syringe.

In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.

In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!
