The Gas You Pass
Source Institutions
Although we may not admit it, all humans fart or pass some gas. In this activity, learners make their own model to mimic food passing through intestines and discover what releases gas.
Freezing Lakes
Source Institutions
In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.
Build a Lung
Source Institutions
Most of the time, we don't have to think about breathing. In fact, you're probably breathing right now without thinking about it!
Snotty Nose
Source Institutions
Our bodies produce snot, or mucus, that we blow from our noses. In this activity, learners will create a model of how snot works and will explore how it keeps our bodies healthy.
What Does Spit Do?
Source Institutions
Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.
Make a Heart Valve
Source Institutions
In this activity, learners make a model of a one-way heart valve to investigate how a heart controls the direction of blood flow.
What's in Your Blood?
Source Institutions
Doctors often send a sample of blood to a lab, to make sure their patients are healthy.
Clogged Arteries
Source Institutions
In this activity, learners explore how eating unhealthy food can damage a heart and arteries.
Make a Lake
Source Institutions
Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?
Water Bugs
Source Institutions
Some bugs can walk on the surface of a lake, stream, river, pond or ocean.
Runaway Runoff
Source Institutions
When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.
Big Sun, Small Moon
Source Institutions
Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.
Window Under Water
Source Institutions
Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.
Dip Dip, Hooray
Source Institutions
Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.
Logs to Soil
Source Institutions
In this outdoor activity, learners cut through and investigate rotten logs and then make log-profile puzzles for each other.
Clear Water, Murky Water
Source Institutions
How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?
The Vaccine & You
Source Institutions
In this card-based personal choice activity, learners review and sort COVID-19 and vaccine science information.
A Better Fly Trap
Source Institutions
In this activity, learners observe fly behavior and then build a flytrap.
Beach Buckets
Source Institutions
In this activity, learners explore a bucket of sand and beach objects.
Delivery Capsules
Source Institutions
Learners make self-assembled polymer spheres as a model for the lipid nanoparticles found in COVID-19 mRNA vaccines.
