A System of Transport
Source Institutions
In this activity about the human heart (on page 5 of the PDF), learners work in teams to simulate the volume of blood moved through the circulatory system by transferring liquid into--and through--a s

Sharks: Taking a Bite Out of The Myth
Source Institutions
In this activity, learners will explore trends in shark populations using shark landing data from the National Marine Fisheries Service.

Catch Your Breath: Build a Spirometer and Measure your Lung Capacity
Source Institutions
In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.

Patterns and Functions: Fill 'er Up
Source Institutions
In this math lesson, learners predict, interpret, and sketch graphs of functions related to the shapes of bottles. A measure of water is poured into a container.

Special Effects: Titanic and Beyond
Source Institutions
In this activity, learners investigate how geometry plays a role in perspective.

Computation and Estimation: Roll Out The Barrel
Source Institutions
In this math lesson, learners apply mathematical modeling to solve a real-world storage problem, in which a manufacturing company is given two options for storing oil barrels.

Changing Shadows
Source Institutions
In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.

Digging Deeper!
Source Institutions
In this activity, learners explore dinosaur skeletons and anatomy. Learners make observations about a T. rex skeleton diagram and then measure the skeleton length and width.

Fruits and Vegetables: Color Your Plate
Source Institutions
In this activity, learners explore healthy choices related to the foods they eat. The importance of a variety of fruits and vegetables to a healthy diet is the focus of the experience.

Rates of Change: Bottles and Divers
Source Institutions
In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

Damsels and Dragons
Source Institutions
In this outdoor activity/field trip, learners conduct experiments to explore where dragonflies and damselflies perch or rest, and how the flies change behavior in reaction to other flies or fly decoys

Battling for Oxygen
Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

Automotive Emissions and the Greenhouse Effect
Source Institutions
In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

Test the Finger Wrinkle Hypothesis
Source Institutions
Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?

Sand Study
Source Institutions
In this geology activity, learners use a microscope to discover and identify the components of sand.

Litter Critters
Source Institutions
In this outdoor activity, learners use a "litter-critter" wheel to help them identify different animals they find living in a natural litter habitat.

Capturing Carbon Dioxide
Source Institutions
In this activity, learners investigate carbon sequestration by creating a carbonated beverage out of apple juice and dry ice.

Neato-Magneto Planets
Source Institutions
In this activity, teams of learners study magnetic fields at four separate stations: examining magnetic fields generated by everyday items, mapping out a magnetic field using a compass, creating model

Up, Up, and Away
Source Institutions
In this math lesson, learners explore the real world meaning of slope. Learners conduct a balloon experiment in which they measure the circumference and flight time of deflating balloons.

What Sort?
Source Institutions
In this activity (on pages 22-33), learners do the kind of work genetic scientists do, sorting and comparing (images of) genetic material strands called chromosomes.
