Digestion
Source Institutions
In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.
Physics Tug of War
Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.
Chromatography Can Separate!
Source Institutions
In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.
Exercise and Memory
Source Institutions
This activity (page 1 of the PDF under SciGirls Activity: Exercise and Memory) is a full inquiry investigation into the effects of exercise on short term memory.
Earth's Energy Cycle: Albedo
Source Institutions
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.
Big and Little Cups
Source Institutions
In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.
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.
The Poor Cartographer: Graph Coloring
Source Institutions
In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.
Trash Traits
Source Institutions
In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.
Experiment with Fat
Source Institutions
In this nutrition/food science activity, learners conduct an experiment and record data to compare the amount of fat in different foods.
Float or Sink?
Source Institutions
In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
The Snack Shop
Source Institutions
In this math activity (Page 11 of the Dining Out! PDF), younger learners count out the total amount of money needed to purchase trail mix using the fewest number of bills/coins possible.
Feet Fit
Source Institutions
In this self-measuring activity, learners measure and record the length of their foot.
Paper Chain Testing
Source Institutions
Learners will do an experiment to determine which type of paper is strongest while focusing on variables and collecting data.
Swing in Time
Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.
Zip Line Zoo
Source Institutions
In this activity, learners build a stuffed-animal zip line. Learners hold a cord against a wall, hook a cute stuffed animal onto it, let the animal slide down, and records its travel time.
Sink or Float?
Source Institutions
In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
Paper Bag Skits: Using Size and Measurement
Source Institutions
Put the math of measurement, numbers, and everyday life into improvisational skits.
Developing Tests to Distinguish Between Similar-Looking Unknowns
Source Institutions
Learners identify an unknown liquid by comparing its behavior to known liquids. Learners drop liquids onto different surfaces and see how the liquids behave.
Plant Parts You Eat
Source Institutions
In this food science activity, learners observe different plant-originated foods.
