Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

In this activity, learners explore an everyday situation, where either of two or more buttons can ring a buzzer.

In this activity, learners explore the many uses of periscopes and how this simple device was designed and is used in many applications.

The demonstration/experiment provides quick proof that air has mass.

In this activity, learners will first learn the basics of galaxy classification and grouping.

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 test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

In this math lesson, learners explore variables and their uses.

In this activity, learners explore how voting systems have changed with engineering advances over time. Learners work in teams to design their own voting system using easy to find materials.

In this math lesson, learners use inchworm measuring tools to measure the lengths of several objects in the room.

In this activity, learners explore the concept of how engineering has made possible the development of--and ongoing improvements to--adaptive devices that serve to help individuals with a wide range o

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

In this activity, learners explore how engineers develop pipeline systems to transport oil, water, gas, and other materials over very long distances.

In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

In this experiment, learners will explore whether increased carbon dioxide makes our oceans more basic or more acidic.

In this activity, learners train to increase muscular strength and improve upper and lower body coordination by performing the “bear crawl” and the "crab walk.” Learners perform the exercises over tim

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.

In this culinary activity, learners use multiple senses (sight, smell, touch, and taste!) to explore real seaweed samples.

Learners will understand the relationship between climate change and sea-level rise.
