In this activity, learners use coverslips to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.

In this outdoor/indoor activity, learners collect ants and dirt to create an ant farm in a cup that they can observe over time.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this construction activity, students use a 2-liter bottle to build a fly trap.

This is an activity (located on page 3 of PDF under Where's Nano? Activity) about identifying nanoscale objects and phenomena in today's world.

In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.

After an interest-generating discussion about "dirt" and microbes, learners select and collect soil samples from a variety of locations (schoolyard, home, etc.).

In this group or individual activity, learners are encouraged to watch birds near home or school—possibly where birds are nesting in a tree, pecking in a park, feeding from a feeder, or flying through

This activity (located on page 4 of the PDF under GPS: Sea Turtles Activity) is a full inquiry investigation into testing a repair material.

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

In this activity, learners grow germs collected from their hands and other objects. They cultivate the germs on a growth medium (such as slices of grapefruit or processed cheese) for a week.

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

In this activity, learners explore the question "What is paper?" Learners discover the processes and materials required to make paper while experimenting with different recycled fibers and tools.

In this activity related to plant biotechnology, learners use restriction enzymes to cut up DNA from a virus called Bacteriophage λ, a process known as restriction digestion.

In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

This activity (on page 3 of the PDF under GPS: Cactus Activity) is a full inquiry investigation into how some desert birds keep their cool.

In this plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.

Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

In this activity (p.24 of PDF), learners make paper with fungi. Learners discover that paper is basically a flat mat of fibers.
