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

In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.

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

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

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

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

In this math activity (Page 8 of the Dining Out! PDF), younger learners select items from a menu and count out the total amount needed using the fewest bills and coins possible.

In this math game (Page 15 of the Dining Out! PDF), learners figure discounts and/or profit increases for various food totals. Learners add decimals to $100.

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.

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity.

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

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

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 work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

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.
