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

This activity (located on page 3 of the PDF under GPS: Farm Animals Activity) is a full inquiry investigation into raising livestock.

In this engineering activity, learners design their own board games.

In this activity, learners will model the mechanical weathering and erosion of rocks in a stream or river.

In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.

In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.

In this activity (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa

In this quick activity about predicting (located on page 2 of the PDF under Where's Nano?

In this activity, learners are invited to imagine the park of their dreams!

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

Historically, sea floor mapping (bathymetry) was done by soundings.

In this creative roleplay activity, learners will explore the various processes of the carbon cycle using movement and props to aid in comprehension.

In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

In this activity (p.3-4 of PDF), learners learn about disease transmission and antibiotic resistance.

This activity helps the learner answer the question: "What environmental problems arise due to animal and human overpopulation and what might need to be done to combat these problems?" Learners play a

In this activity, learners use a fictitious map of "Tourist Town" and counters to problem solve how to place ice-cream vans on street intersections so that every other intersection is connected to one
