In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.

In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

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

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

In this water activity, learners discover ways to move water across the water table.

In this activity, learners make their own bug boxes and test the habitat preference of selected "minibeasts" (bugs).

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

This is an activity (located on page 3 of PDF under Where's Nano? Activity) about identifying nanoscale objects and phenomena in today's world.

In this math lesson, learners explore tessellations through literature, music, writing, and art activities.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity, learners explore the different heating properties of soil and water.
