In this nutrition activity, learners explore food labels and consider the nutritional value of foods. Learners also explore units of measurement commonly used on food labels.

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.

In this nutrition and estimation activity (page 12 of PDF), learners estimate serving sizes of different foods and compare their estimates to serving size information provided on nutrition food labels

Through this nutrition activity (page 5 of the PDF), learners will understand—and probably be surprised by—how big serving sizes of various foods should be.

In this graphing activity (on pages 33-40), learners investigate how much and what kinds of food sea otter pups eat during their first year of life.

In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.

In this math lesson, learners identify and compare unit costs of given items. Learners use computation skills, problem solving and number sense to find the cost of an ounce of cereal.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this health, cooking, and math activity, learners explore nutrition and examine nutrition labels.

In this life science activity (page 8 of the PDF), learners explore the carbon cycle by mixing yeast, sugar and water.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

In this math lesson, learners use slices of bread and geoboards to explore several ways to divide a rectangle in half. Learners also identify equivalent fractions that represent one-half.

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.

This is a classic exercise for visualizing the scale of the Solar System.

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

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi
