In this activity, learners explore dinosaur skeletons.

In this activity, learners explore dinosaur fossils by making an edible treat. First, learners read "Dinosaur Bones" by Aliki to examine how fossils are formed.

In this hands-on art and science activity (page 4 of the pdf), learners brainstorm and discuss how humans use wetlands, then express their understanding of the subject in artwork.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most to learn about the different sizes of dinosaurs.

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

In this ecology activity, learners make a model water-based ecosystem called a terraqua column. The column (in a large soda bottle) includes pond water, duckweed, sand or gravel, and small snails.

Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of water.

In this thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community.

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this activity, learners will explore trends in shark populations using shark landing data from the National Marine Fisheries Service.

In this activity, learners explore dinosaur skeletons and anatomy. Learners make observations about a T. rex skeleton diagram and then measure the skeleton length and width.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

In this activity, early learners simulate fossil prints in play dough or clay.

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

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.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this activity, learners model how the Moon's volcanic period reshaped its earlier features.

In this multi-station lab, learners conduct a series of experiments to explore the processes and effects of weathering and erosion.
