Scientific Inquiry
Middle schoolers make inferences about what activities occur at different places in school. They form a hypothesis as to how space is used. They simulate how archeaologists explore past people by designing and conducting a research project.

Wood Identification Based on Density
Eighth graders measure irregular and regular shaped solids. In this investigative lesson students calculator volume, mass and density of wood and blocks.
Science 4 Inquiry
The Ins and Outs of Photosynthesis
The most important chemical process on Earth is photosynthesis. Scholars explore the changes in the gases in our atmosphere as life on Earth developed. They create a model of photosynthesis and consider simple questions.

The Moons of Jupiter
Middle schoolers analyze given data on density and diameter of objects in space by graphing the data and then discussing their findings. This ninth installment of a 22-part series emphasizes the Galilean moons as compared to other objects.
Curated OER
Exposure!
Students investigate that chemicals may affect different people in different ways. They also realize that their perceptions of dangerous materials may not be realistic and that the news media may not provide all the information needed to...
Beyond Benign
In a Lather
Time to come clean! Scholars continue preparing the shampoo they created in the previous two lessons. The purpose of this stage is to calculate the perfect amount of additive to make the shampoo lather.

Bacterial Transformation: Laboratory Experiment
Students participate in a group lab in which they complete the process of bacterial transformation. If lab procedures are followed correctly, Students see their results in a few days...bacteria glowing green.
Curated OER
Semipermeable Membranes and Bioaccumulation
Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....

Respiratory System
Explore the respiratory system with a model. First, pupils build a set of lungs to experiment how they inflate and deflate. Then, they delve deeper into the topic with a web quest to discover new information about the nose, trachea, and...
NASA
Tools of the Trade
Did you know every state in the U.S. has at least one observatory? During the lesson, scholars research the cost of building and maintaining an observatory. They must present their information in a proposal to build a new observatory,...

Revising an Investigation
Write, edit, and then revise! The fourth lesson in a five-part series asks peers to provide feedback on research. Individuals then use the research to edit and revise conclusions and develop their presentations.
Curated OER
Perceived Risks
Learners rank a list of everyday risks to compare with classmates. They rate each risk on both its ability to be controlled and its observability in the environment. Results are graphed.
Curated OER
Skin Cancer Investigation: A Multi-Component Project
Students compare the perceived and actual risks of getting skin cancer, while looking at ways to minimize these risks. They may have very little grasp of the severity of the threat of skin cancer or be unaware of the increase in the...
