In this exercise, students complete a simulation of human karyotyping using digital images of chromosomes from actual human genetic studies. They will arrange chromosomes into a completed karyotype, and interpret their findings just as if they were working in a genetic analysis program at a hospital or clinic.

In this lesson, students work toward understanding the limitations of renewable energy resources if there is no system available for storing the energy. First, students watch a video segment on the engineering design process. Then they are challenged to design a storage system for renewable energy. They brainstorm and research ways in which renewable energies such as solar and wind power can be stored. Then students present their final designs. During this lesson, students should come to understand the steps in the engineering design process and how engineers design systems that convert energy from one form to another and store it for later use.

In this simulation activity, students take virtual coral samples and use radiometirc dating techniques to calculate the age of the living and dead corals in the sample area. They will then use this information to determine the environmental conditions on the seamount.
Material Type: Interactive
In this activity, students calculate the average distance of each planet from the Sun scaled to a football field drawn and measured out on a 30 x 35 cm paper.
Material Type: Unit of Study
In this lesson, students compare two different herds of elk to determine how many have been affected by the disease brucellosis. They will collect and analyze data to explore how the disease can spread and affect population density. This lesson begins on page 38 of the pdf.
Material Type: Lesson Plan
In this activity, students will collect and examine aquatic snails. They will identify the parts of a snail as well as determine the number of species present in the environment. Students will collect, mark, return to the water and recollect snails in order to collect data that will allow students to make an estimation of the snail population.

This scientific article provides anatomical features and the adaptive advantages of those features of owls and giraffes. The text is written for native speakers 9 years and up.
Material Type: Reading
In this lesson, students learn that microorganisms can be both beneficial and harmful; one benefit is their decomposer role in the cycling of matter.
Material Type: Lesson Plan
In this lesson, students will learn that all matter can be classified as either a pure substance or a mixture. They will also learn that both mixtures and pure substances can be broken down into subcategories and that there are techniques chemists use to determine in which category a sample of matter belongs.
