Learners conduct a "blind" taste-test of several types of enhanced or fitness water drinking water that has commercially added substances like vitamins, sugars, or herbs.

In this yummy biology activity (page 3 of the PDF), learners participate in a demonstration of natural selection.

In this activity on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases.

In this activity on page 2 of the PDF (Get Cooking With Chemistry), learners conduct chemical tests on certain powders used in cooking.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity (on pages 34-39), learners make a fairly detailed model of DNA using licorice and gumdrops.

In this activity, learners conduct tests for proteins, glucose, and starch.

In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

In this activity, learners design a crushing test and discover that identifying and controlling the variables may be difficult.

Esta actividad enseña la proporción y razón por hacer que los aprendices hagan "ensaladas" que combinan tres tipos de frijoles en tres combinaciones diferentes.

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

In this math activity, learners guess which cereals contain the most sugar. Learners use the nutrition labels on the cereal boxes to find the cereal with the least amount of sugar.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a

In this challenge, learners figure out how to make a juice stain disappear.

In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.
