High schoolers attempt to understand seasonal variation by viewing images of the energy received by the earth. In this weather lesson, students view images from NASA of the influx of energy from the sun and make predictions about...

Photosynthesis requires energy and produces food, and cellular respiration produces energy and requires food. An interesting lesson analyzes the factors that affect the rates of photosynthesis and respiration. Classes spend one day...

Explore a 1900s lunch pail. In this oral language and 1900s history lesson, students view a photograph of an old-fashioned lunch pail. Students describe the object and make predictions about what it is and its possible uses. Students...

High schoolers complete a unit of lessons on the events that led to U.S. involvement in WWI. They complete a Webquest, conduct research, complete a Venn diagram, read and discuss the reasons for entering the war, and create a slideshow.

Help your class make a connection between salt water and nanoscience. In the introductory lesson of a seven-part unit, the class explores why salt water helps a sore throat feel better. Pupils conduct preliminary research about the...

Students explore the density of soap. In this science instructional activity, students conduct an experiment to find which types of soap will float. Students make a hypothesis and record their observations.

Students investigate the effect of a chemical (they choose) on the germination of seeds. They calculate % chemical concentrations in water, form a hypothesis, and discuss the ethics of using animals in biomedical research.

Young scholars conduct an experiment. They review how to use the scientific method to conduct an experiment with white carnations and food coloring. They create a hypothesis and test it to better understand how plants get nutrients,...

Students conduct observations using their five senses. In this science lesson plan, students describe different states of matter. They investigate the factors affecting mold growth.

Students describe the movement of the Earth as it relates to the sun and formulate a hypothesis for the movement and the changing length of the shadow. They express the relationship between the sun and the Earth and how that causes the...

Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. In this geologly lesson plan, learners use scientific equipment to...

Are serving sizes for different foods always appropriate for what you need? In this hands-on activity, learners work in groups to estimate what one serving size of various foods are, and then evaluate their hypotheses by measuring...

This project provides students the opportunity to investigate parasites as a possible cause of the observed frog deformities. It asks students to view web-based evidence and interpret whether it supports the parasite hypothesis. Students...

Test your knowledge of tests of significance. A curriculum model for AP® Statistics describes and defines power in terms of tests of significance. It also provides two classroom activities designed to investigate power and how it relates...

Horrible science puns only happen periodically, but the scientific method is forever. Young scientists observe two presentations on the scientific method, complete independent practice worksheets, and integrate their knowledge through a...

These slides will activate prior knowledge with real-life examples of natural selection. The predictions and outcomes for those examples are explained. Your students will like the information about the relevant chromosome tests that can...

How do scientists determine what questions to ask to meet their research goals? Help your class develop an inquiry mindset with a lesson based on studies in the Gorongosa National Park. Partners create their own research questions by...

Herbivores and carnivores just don't get along. Using a box of animal crackers, classes collect data about the injury status of herbivores and carnivores in the box. They complete the process of chi-square testing on the data from...

Very few universities still offer a master's degree in the ecology of grasses, but that was the degree that led George Wells Beadle to an interest in genetics and later a Nobel Prize. Scholars learn about the discoveries of Dr. Beadle...

Not all linear functions are linear transformations — show your class the difference. The first lesson in a unit on linear transformations and complex numbers that spans 32 segments introduces the concept of linear transformations and...

Students perform simple and fun experiments to use the scientific method, take careful notes, and write a lab report. They first make and test a hypothesis about how many drops of water they can fit on the face of a penny and then test...

What will happen in Hatchet by Gary Paulsen? Kids read a series of possible events that will occur in the novel and mark whether they agree or disagree with the probability of each event happening.
