In this matching game, learners study the limits of life on Earth to see what other places in the solar system might sustain microbial life.

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

In this activity (page 7 of pdf), learners research tide pool ecosystems, and then create brochures that "advertise" these environments.

This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

During this lesson, learners will determine their blood pressure and learn about systolic and diastolic pressures.

In this activity about neuron/target muscle recognition (page 44 of the PDF), learners arranged in two rows facing away from each other use string to simulate neural development.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

In this online simulation, learners use antibiotics to cure patients with bacterial infections.

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.

Directed by instructional cards, learners kinesthetically model cell communication by acting as components in a cell signaling pathway.

In this art-related activity, learners make a coin rubbing—a process similar to what archeologists may do with ancient artifacts. This activity can be used in connection with a history or art lesson.

In this investigation learners explore the differences between, and interdependence of, living and nonliving elements in a water ecosystem.

In this activity, learners examine the different materials gardeners add to their soil, and discuss how these materials are important for plant growth.

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

Learners work in teams to investigate how scientists use physical characteristics to classify living things.

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 four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

In this activity, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.

Design and create an optical illusion toy that makes two pictures appear to become one. This is called a thaumatrope and will allow the learner to investigate the phenomenon of persistence of vision.
