In this activity, learners follow simple historical maritime recipes to cook up hardtack and swanky, and then compare the foods they eat to what was served on ships in the past.

In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.

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 nutrition activity (page 26 of PDF), learners consider the nutritional needs of people with specific dietary requirements, such as athletes, persons with diabetes and vegetarians, and create a

In this activity, learners observe what happens when yeast cells are provided with a source of food (sugar). Red cabbage "juice" will serve as an indicator for the presence of carbon dioxide.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

In this activity, learners will simulate the interactions between a predator population of gray wolves and a prey population of deer in a forest.

This is an outdoor activity designed to demonstrate evolution of feeding behavior in flocking, schooling or herding animals that maximizes allocation of food resources and enhances survival.

This activity (on page 3 of the PDF under GPS: Animal Scent Activity) is a full inquiry investigation into animal behavior.

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

This is an activity (located on page 3 of the PDF under Self-Assembly Activity) about self-assembly, the ability of molecules to assemble themselves according to certain rules.

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

In this activity, learners will make their own slushies and learn some of the science behind how the process works.

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 (page 5 of pdf), learners explore the relationships between the shape and structure of a shark's teeth and the food it eats, and then create their own shark tooth from clay.

In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.
