Evolution in Action: Isolation and Speciation in the Lower Congo River
Source Institutions
In this guided discussion activity, learners watch a video about Central Africa's Lower Congo River, one of the most biologically diverse rivers in the world.

Making a Field Journal
Source Institutions
In this activity, Christina Elson, an archaeologist from the American Museum of Natural History, guides learners as they investigate an "artifact" and record their observations in a field journal.

Measure Your Ability to See
Source Institutions
In this exercise (Activity #2 on page), learners test their distance vision to evaluate their overall eyesight.

Hand Biometrics Technology
Source Institutions
In this activity, learners explore how engineers incorporate biometric technologies into products as well as the challenges of engineers who must weigh privacy, security and other issues when designin

The Vaccine & You
Source Institutions
In this card-based personal choice activity, learners review and sort COVID-19 and vaccine science information.

Head, Shoulder, Knees and Toes...and Hands, Fingers and Back
Source Institutions
Are fingers the only place on the body where we use our sense of touch? In this activity (6th activity on the page), learners test the touch sensitivity of different parts of the body.

Air Pressure and Dent Pullers
Source Institutions
In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

Interactive Gumball Machine
Source Institutions
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.

Having a Gas with Water
Source Institutions
In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.

The Dead Zone: A Marine Horror Story
Source Institutions
In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

Biotech in a Bag
Source Institutions
In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.
Without An Ark: The Effects of Storms and Floods
Source Institutions
April showers bring May flowers, but what do coastal storms bring?

Water Rocket Launch
Source Institutions
In this activity, learners explore rocketry and the principals of space flight.

Sort It Out!
Source Institutions
In this activity, learners explore how engineers have developed sorting systems which integrate into manufacturing and packaging processes. Learners explore how coins are made.

Catapult
Source Institutions
In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

The Parachuting Egg
Source Institutions
In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

Plankton Races
Source Institutions
In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

Design and Build a Better Candy Bag
Source Institutions
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.

Currently Working
Source Institutions
Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

Modeling the Night Sky
Source Institutions
In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.
