Curated OER
Cells, The Structural and Functional Units of Life
Students observe the general structure and organelles of plant and animal cells. Students prepare microscope slides of elodea, onion, check, and cork and identify the cells by size and shape as unicellular, multicellular, plant or animal.

Determination of Tensile Stress-Strain Common Properties in Materials
Students demonstrate the relationship between stress and strain, then graph stress-strain curves for various common materials. Students interpret graphed results and discuss differences in mechanical properties of materials.
Curated OER
Form and Function in the Marine Environment
Students study the relationship of form and function in the marine environment.
Curated OER
Simple Machines
Students 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 and...
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
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
Learners 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. Learners analyze the lobster claw as a mechanical lever.
Curated OER
Scientific Notation I: The Exponent
Students manipulate and interpret large numbers expressed in the "exponent" format of scientific notation.
Curated OER
Porosity
Learners 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 rock...

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
Students 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.

Protein Biochemistry: Evidence for Charged Amino Acids in Proteins
High schoolers 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...

What Is the Freezing Point?
Middle schoolers 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
Young scholars 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
Learners examine the effects of cocaine and heroin and withdrawal symptoms. In this drug lesson students participate in an activity that illustrates cocaine's actions.
Curated OER
Consistent Circles
Students create a design of a circle. In this geometry lesson, students identify the measure of the diameter and radius of a circle. They graph and analyze their collected data and write equations based on direct variation.
Curated OER
Constructing Midsegments of Triangles
Students construct midsegments. In this geometry lesson, students make conjectures and apply properties of triangles to solve problems. They complete an activity on the computer.
Curated OER
Circumscribed Polygons
Students investigate polygons and construct ferris wheels. In this geometry lesson, students create a circle and differentiate properties of circles and polygons. They compare the relationship between angles and circumscribed polygons.
Curated OER
Investigating the Earth-Moon-Sun System
Eighth graders research Native American legends involving the sun, moon, and stars and compare them to the origin of present day knowledge. They create a written report and make an oral presentation of their findings to the class.
