In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

In this math lesson, learners are introduced to proportional reasoning through modeling, sharing, and questioning techniques.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

In this math activity, learners use gingerbread cookies to collect and organize simple data. First, learners read "The Gingerbread Boy" by Paul Galdone.

In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.

In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.

In this math lesson, learners make estimates to analyze the number of apples per acre, and visualize the magnitude of one million.

In this data analysis activity, learners use data collected by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to study Chilean sea bass populations.

In this activity, learners build one or more edible coral polyps and place them together to form a colony.

In this math lesson, learners apply the concepts of ratio and proportion to the capture-recapture statistical procedure.

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.
