Filling in the Picture
Learners study archaeological sites. They discover some of the problems inherent in choosing sites and what parts are chosen for excavation. They evaluate and explain their choices for study and articulate the process of archaeological...

Creating an Enzyme-Substrate Model
Students explore the reaction rates of an enzyme-mediated reaction through experimentation. In small groups, they use everyday objects to demonstrate the effects of environmental variables on enzyme function.
Students graph and...

An Enzyme- Substrate Model
Young scholars explore reaction rates of an enzyme-mediated reaction. They examine the effects of environmental variables on enzyme function. Students collect, graph, and analyze data relating to the reaction.

How Old Is Mike?
Young scholars examine the absolute dating of fossils, they use a list of names and ages to determine the difference between relative age and absolute age. They explore the relative age and absolute age of people and of fossils.

Archaeological Inquiry
Students describe what they see as they observe an "artifact". They draw conclusions based on the information gathered to identify what the artifact might be used for and determine how old it might be.
Curated OER
Pieces of the Past
Students study the importance of preserving the archaeological record. They write a paragraph describing an object and why it is important to them. They cut their paper into a puzzle and compare their own to the student they trade with.

Fighting Infection
Students study immune responses and the structures that are related to immune cells functions. In this fighting infection lesson plan students construct antibody complexes and model the interaction of the immune system when it is...

Observing Osmosis in a Chicken Egg
Tenth graders develop a hypothesis and explain what they observed on an activity. In this investigative lesson students observe osmosis and report their data using a graph.
Curated OER
2 x 2
Students work together to grid a 2 x 2 meter unit using the formula for the Pythagorean Theorem. After creating the grid, they identify the location of artifacts and create a map of their location. They develop a graph and table of their...
