This fun hands-on astronomy activity lets learners use star maps (included) to find constellations and to identify stars with extrasolar planets (Northern Hemisphere only, naked eye).

This activity was designed for blind learners, but all types of learners can use it to organize an interactive model for learning the classification system (taxonomy) of living things.

In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.

Learners manipulate opaque, sealed boxes and attempt to determine their interior structures. Each box contains a moving ball and one or more fixed barriers.

In this outdoor, night activity, learners track nocturnal animals' footprints, droppings and other signs of their presence.

In this activity, learners discuss how life is defined and conduct a simple experiment, looking for signs of life in three different “soil” samples.

In this creative activity, learners will practice looking carefully to observe details and to become familiar with dioramas as a method for displaying naturalistic scenes.

On an imaginary fossil hunt, learners "find" (remove from envelope) paper "fossils" of some unknown creature, only a few at a time.

Learners explore the physical properties of a variety of balls and how they bounce.

In this activity, learners create channel features with flowing water, comparing their observations to real images of Mars and Earth taken by satellites/orbiters.

In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.

In this activity (on pages 2-8), learners experience how scientists use classification in their study of animals.

In this lesson, learners are challenged to discover the relationship among six numbers.

Learners use scientific processes to solve a crime. As they get clues, learners must create a hypothesis then adjust that hypothesis as more information is revealed.

In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft.

In this activity, learners create their own archaeological profiles.

In this math activity, based on the research of famed astronomer Frank Drake, learners calculate the possibilities of finding intelligent life elsewhere in the universe besides Earth.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this activity, learners work in teams to investigate the composition of unseen materials using a variety of tools.

Learners imagine they are paleontologists in Florida, where they find (remove from envelope) paper "fossils" of some unknown creature, only a few at a time.
