So many bodily activities depend on homeostasis! Give learners a solid background to understand the basic process of the human body. Scholars first examine negative feedback loops contributing to body temperature regulation and then a...

After an introduction to municipal sludge, middle school ecologists consider the pros and cons of dumping in the Hudson River Canyon. The class is split into two groups: one to debate in favor or dumping and one to debate against the...

Young scholars 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...

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...

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.

For this active transport worksheet, students review the cellular process of active transport including the structures and functions of the cell organelles involved. This worksheet has 28 fill in the blank statements.

Students 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.

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.

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.

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

Tenth graders develop a hypothesis and explain what they observed on an activity.  In this investigative lesson plan students observe osmosis and report their data using a graph. 

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...

Endocytosis enables cells to absorb extracellular nutrients that are needed for their survival. In receptor-mediated endocytosis, a protein receptor on the cell membrane binds to a nutrient molecule and facilitates its absorption through...

Students use chocolate candies to simulate the process that occurs in saturated soil when Fe3+ is reduced to Fe2+ due to a microbial mediated redox reaction.

The different types of autophagy are broken down and described, including macroautophagy, microautophagy, and chaperone-mediated autophagy. The role of autophagy in cell death is also discussed.

The cellular processes of exocytosis and endocytosis are described and a table comparing them is provided. Includes examples.
