Food Forensics: A Case of Mistaken Identity
Learners develop an experiment to test a hypothesis. They use their knowledge of antigen-antibody specificity to develop a hypothesis. Students articulate that the antibody-antigen specificity is one part of the immune system. They...

Exploring the Dynamic Nature of the Sun
Students compare and contrast images of the sun taken at different times and viewed at different scales. They record their observations in a journal and create a graphic organizer to help analyze their observations.
Curated OER
Buoyant Force
Students investigate the scientific concept of why some objects float when put in a liquid solution. They apply the laws of motion and force while conducting classroom activities. Students also take notes and answer target questions to...

Is Organic Food Worth the Extra Cost?
High schoolers calculate the amount of pesticide residue in selected foods for two
pesticides and determine if these levels are safe. They read an article about a
research study looking for metabolites of these pesticides in children....

The Emergence of the Judicial Branch
Learners demonstrate understanding of both sides of the argument between Jefferson and Marshall that led to the strengthening of the Judicial Branch through the creation of judicial review.
Curated OER
Carbon Dioxide Heats It Up
Students design an investigation to test whether vegetation in an area helps regulate the ambient air temperature. They make comparisons between the investigation and global changes in climate. In groups, they present their findings to...
Curated OER
DNA in a "Snap"
Students observe a model of DNA and answer probing questions like, "What does this model represent?" They then work in small groups to construct an accurate model of DNA per rubric provided and present to the class explaining their model...

Botanical Discoveries
Sixth graders study the chronology of major events of the Lewis and Clark Expedition. They use primary and secondary resources to obtain information about the plants which were identified by Lewis and Clark.
Curated OER
Solids, Liquids, and Gases
Students explore the three main forms of matter: solid, liquid, and gas. They examine concrete examples of each, using their five senses and "experimenting" to find differences in them. They find pictures of each, cut them out and past...

Good Vibrations: Building a Wave Model
Young scholars assess and apply recurring patterns in natural systems. They evaluate the wave properties of frequency, wavelength, and speed as applied to sound. Students develop a relationship to quantify aspects of wave motion. They...
Curated OER
Waves, Sound, and Light
Ninth graders explain waves in terms of energy transfer and describe their basic types and characteristics. They solve mathematical problems involving wavelength and frequency. Students conduct experiments in reflection and refraction.
Curated OER
Where in the World is Carbon Dixoide?
Students conduct experiments designed to detect the presence of CO2 by using a BTB that changes color (blue to yellow) in the presence of CO2. First, students experiment with the CO2 from combining vinegar and baking soda. In part two,...
