In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

In this Energy and Environment activity (page 9 of the PDF), learners calculate the mass of a piece of gum, compare it to the mass of the gum's packaging, and then create a bar graph of the results.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

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.
