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

In this activity, learners can create five-layer density columns by employing one of three (or all) methods.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

In this activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.

In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

In this activity, learners build styrofoam boats powered by twisted rubber bands.

In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.
