Modeling Day and Night
Source Institutions
In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.
The Geophysical Light/Dark Cycle
Source Institutions
This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.
Meteoroids and the Craters They Make
Source Institutions
In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.
Skin Deep
Source Institutions
In this activity, learners explore how to protect their skin while applying pesticides to plants.
The Rumblin' Road: Determining distance to a Thunderstorm
Source Institutions
In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.
Water Clean-up
Source Institutions
This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.
Water Body Salinities II
Source Institutions
In this activity, learners discuss the different salinities of oceans, rivers and estuaries.
Jell-O Model of Microfluidics
Source Institutions
This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.
Toxic Popcorn Design Challenge
Source Institutions
In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.
Be a Scanning Probe Microscope
Source Institutions
In this activity, learners investigate Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano
The Carbon Cycle and its Role in Climate Change: Activity 3
Source Institutions
In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.
DNA Detective
Source Institutions
This activity is about collecting and analyzing DNA as part of a criminal investigation.
Salts & Solubility
Source Institutions
In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.
Shake it up with Seismographs!
Source Institutions
In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.
Paint by the Numbers
Source Institutions
In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.
Jump for the Moon
Source Institutions
In this activity, learners will train to increase bone strength and to improve heart and other muscle endurance by performing jump training with a rope, both while stationary and moving.
Piecing It All Together
Source Institutions
Learners create their own piece of history by decorating, shattering, and piecing together a flowerpot "artifact".
Rubber Blubber Gloves
Source Institutions
In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.
Forensic Science: Hair Sample Investigation
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Forensics) is a full inquiry investigation into how hairs from a crime scene are matched to suspects.
Spill Spread
Source Institutions
In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.
