In this activity, learners will dissect a pumpkin or winter squash to learn the parts of the plant. This activity gets your learner hands on with every part of the plant and will be messy.

Learners make a "menu" of any plants in their lunch for Monday through Friday and draw the plants from their lunch.

In this activity (p.23 of PDF), learners dye wool with fungi. Learners discover that natural chemicals in fungi can dye wool different colors.

In this online interactive, learners use fossils to infer temperatures 55 million years ago, at the sites where the fossils were found.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

In this activity, learners explore why animals, specifically dinosaurs, live in families.

In this activity on page 4 of the PDF, learners investigate the importance of washing their hands.

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.

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.

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

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

In this series of exercises, learners predict the conditions necessary for bacterial growth, test their predictions and at the same time practice the aseptic techniques and safety procedures needed wh

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

In this activity (on pages 30-36), learners simulate a dig for ancient pollen, to experience how paleobotanists study fossilized pollen in rocks to learn about early geological and climatological even

In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.
