Form and Function in the Marine Environment
Students study the relationship of form and function in the marine environment.
Curated OER
Ice Cold
Students design and conduct an experiment to investigate what happens when salt and ice come together and to determine if one form of salt is better for melting ice on steps and sidewalks.
Curated OER
Simple Machines
Young scholars discover what simple machines are and identify a gear, a pulley, and a lever. In teams, they build at least two models each of simple machines and challenge them with specific instruction cards. Finally, students present...

Introduction to the Scientific Method
Students designs and conduct a scientific experiment that identifies the problem, distinguishes manipulated, responding and controlled variables, collects, analyzes and communicates data, and makes valid inferences and conclusions.
Curated OER
Making Your Own Sampling Tools
Students examine cause-and-effect relationship between human attitudes and behavior in the environment. They also assist citizens in increasing their sensitivity and stewardship for the environment.

Analysis of Lobster Claw Function. An Exercise in Biomechanics
Students observe two chelae. They write three differences they observe in their notebooks. Students suggest a hypothesis which would explain these differences. They dissect the chela. Students analyze the lobster claw as a mechanical lever.
Curated OER
Porosity
Young scholars predict and test the porosity of sediments with particles of different sizes. They name two objects that they think has pores. Students define the term porosity and pores. They comprehend that an aquifer is the porous...

Adhesion of Caulks to Surface - Testing Product Quality
Students investigate quality products. In this Physical Science lesson plan, students will test three different types of caulking. The students are looking for the caulk with the best adhesion after two days of curing.
Curated OER
Dividing Line Segments into n Congruent Parts
Young scholars identify lines, and line segments. In this geometry lesson, students divide line segments into equal congruent parts. They complete a laboratory activity dealing with lines and segments.
Curated OER
Protein Biochemistry: Evidence for Charged Amino Acids in Proteins
Students add the acid and base drop wise as the protein precipitates. If either are added too rapidly, students may miss detail or the protein may not have sufficient time to renature. Casein does not buffer the solution well when it is...
Curated OER
What Is the Freezing Point?
Students remove heat energy and determine how it causes a phase change.
Curated OER
The Average Atom - Isotopes
Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.
Curated OER
Women in Science
Students study the roles that women have played in science throughout history. They work in small groups while visiting the Smithsonian National Museum of American History.
Curated OER
Cocaine in the Brain
Students examine the effects of cocaine and heroin and withdrawal symptoms. In this drug lesson students participate in an activity that illustrates cocaine's actions.
