In this activity, learners discover how geologists use stratigraphy, the study of layered rock, to understand the sequence of geological events.

Fossilized Dinosaur Teeth Adaptations
Source Institutions
In this activity, learners use models of fossilized dinosaur teeth to understand how dinosaur teeth were used.

Excavating and Mapping Under Water
Source Institutions
In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

Start a Rock Collection
Source Institutions
Learners follow a three-step process to start their own rock collection.

Glaciers
Source Institutions
In this online activity, learners adjust mountain snowfall and temperature to see how glaciers grow and shrink. They will use scientific tools to measure thickness, velocity and glacial budget.

Name-a-Saurus
Source Institutions
In this paleontology activity, learners explore the system behind dinosaur nomenclature.

Fossils: Observing, Making and Learning
Source Institutions
In this activity, learners explore how casts of fossilized bones are created and used to learn about dinosaurs. Learners make observations, draw diagrams and share their findings.

Clean Water: Is It Drinkable?
Source Institutions
In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

The Carbon Cycle and its Role in Climate Change: Activity 3
Source Institutions
In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

Decomposition Column
Source Institutions
In this activity, learners turn empty 2-liter bottles into a see-through compost container.

Familiar Fossils
In this activity, learners explore different types of fossils by making their out of dough and objects from around the house.

If Trash Could Talk
Source Institutions
Ancient trash tells archaeologists a lot about the past. In this activity, learners take a close look inside their trash can and think about the clues it offers about their lives.

Cookie Subduction
Source Institutions
This is a quick activity that shows how large amounts of rock and sediment are added to the edge of continents during subduction.

Bone Identification
Source Institutions
This activity (page 3 of the PDF under SciGirls Activity: Dinosaurs) is a full inquiry investigation into fossil hunting and identification.

If You Lived in a Forest
Source Institutions
This activity encourages learners to focus on the natural environment of the Eastern Woodlands before the arrival of European settlers.

Woodlands Map
Source Institutions
This is a culminating activity which allows learners to summarize what they know about Woodlands Native Americans by creating illustrations and map symbols for a large outline map (see related Activit

How We Know What The Dinosaurs Looked Like: How Fossils Were Formed
Source Institutions
In this activity (p.7-8 of PDF), learners examine fossil formation.

Vanishing Craters
Source Institutions
In this activity (on pages 12-15), learners make a crater model and test the effects of weather (rain) on its surface.

Piecing It All Together
Source Institutions
Learners create their own piece of history by decorating, shattering, and piecing together a flowerpot "artifact".

Future Moon: The Footsteps of Explorers
Source Institutions
In this activity, learners drop impactors onto layers of graham crackers!
