Mix and Match
Source Institutions
In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.
Rotating Light
Source Institutions
In this activity, learners explore what happens when polarized white light passes through a sugar solution.
Exploring Baking Powder
Source Institutions
In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.
Bready Bubble Balloon
Source Institutions
Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.
Toxic Popcorn Design Challenge
Source Institutions
In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.
Dunking the Planets
Source Institutions
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.
Nano Ice Cream
Source Institutions
In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.
Rice Handle
Source Institutions
In this physics activity, learners attempt to lift a jar full of rice using only a spoon.
Leaves: Extracting Pigments
Source Institutions
In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.
Instant Ice Cream
Source Institutions
In this activity, learners make instant ice cream without using a freezer.
Checking For Starch
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will observe a chemical change, specifically what happens to iodine when it is applied to ripe and unripe apples.
DNA Extraction
Source Institutions
Learners use a simple process to extract DNA from strawberries.
Testing Falling Peanut Butter Sandwich Myth
Source Institutions
In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi
What Molecules Make the Holes in Bread?
Source Institutions
In this activity, learners will discover why there are holes in bread.
Do Plants Need Light?
Source Institutions
In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.
Edible Glass
Source Institutions
In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.
Energy Sources
Source Institutions
In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.
Lost Labels
Source Institutions
In this experiment, learners will conduct chemical and physical tests to identify mystery substances.
Ice Cream Shake
Source Institutions
In this tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.
Design a Flavor: Experiment to Make Your Own Ice Cream Flavor!
Source Institutions
In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.
