Do scientists really change their minds when presented with new evidence? Young scientists learn about two competing theories and must decide between them. They perform a simulation and have access to actual field data. Then, scholars...

The pocket mouse can be light brown like the sands of the desert, or dark brown like the volcanic lava flows that are interspersed throughout New Mexico's Valley of Fire. It seems that predators have weeded out light colored mice in this...

Sort through the "junk drawer kingdom" as the protists laugh at our attempts to classify them! AP biology classes consider the array of organisms that do not file neatly into the other four kingdoms of classification. Evidence for the...

Learners examine the hierarchy theory and biotic organization by playing a teacher-created card game matching groups of items, such as organelles, in suits of four. They discuss the reasons for their hierarchical organization of the...

If your pupils think a catalyst is a list of their cats, then this might be the lesson for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...

Drug addiction, including prescription drug addiction, begins with a reason that's different for every user. High schoolers learn more about the reasons people begin abusing drugs with a set of videos and worksheets that discuss four...

Engage young biologists with four laboratory activities that explore the fossil record. Learners examine fossil images, a fossil kit, the rock record, and geologic time scale. They even experiment with the oxygen production of an Elodea...

Young scholars verbalize a simple particle theory, They apply their particle theory to explain what happens during chemical reactions and how this theory supports the law of conservation of matter. Pupils comprehend that the atomic...

In this molecular shapes worksheet, learners read about how to predict molecular shapes in molecules based on the number of electron pairs and the VSEPR theory. Students are given twelve molecules, they draw the Lewis structures and...

For this universe worksheet, students read about the big bang theory and the evolution of the stars from the elements. Students answer four critical thinking questions about the beginnings of our universe.

Students explore the Big Bang Theory and discover how it can be used to explain the origin of the universe. For this Big Bang Theory lesson plan, students use a balloon with colored paper inside, blow it up and pop it, group the colored...

A lesson allows you to go back in time and see the big bang actually happen. Bazinga! In reality, pupils research the Big Bang Theory and theorize what it would be like to go back in time and see it happen. There are four...

Investigate the theories of human evolution. In this research based lesson, learners research and discuss how geographic isolation, interbreeding, generalization, and specialization are factors in the history of humans. Groups work...

Start this lesson with a bang! The eighth in a 13-part series of lessons explains the origin of elements beginning with the Big Bang Theory. The reading describes the formation of elements hydrogen through uranium.

A presentation on Darwin's theory of evolution and natural selection could be a good addition to your biology class. It provides general information about how animals adapt to their surroundings, as well as how organisms create more...

Astronomers only observe four percent of the universe as the rest hides in darkness. The size, shape, and movement of the universe are the focus for an long-term high school unit. Its 43 lessons include hands-on experiments, direct...

Middle schoolers define terms and watch a segment from a film.  In this scientific theory lesson plan students work in small groups and draft a theory that was discussed in the program. 

Explore the history of cholera and its effect on society with your biology class. Young biologists will then proceed to grow their own germs, prepared from live cultures, and follow the steps of the scientific method to generate data....

How do scientists provide evidence to support the theories they put forth? What clues do they put together to create these theories? After watching West of the West's documentary Island Rotation class members engage in a series of...

Students participate in a small group read aloud of the short story, "Cerium" by Primo Levi. They answer several questions about the story and then relate the reading to a lecture on Kinetic theory. After the lecture they apply the...

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

In this crystal field theory worksheet, students practice using the theory to calculate high and low spin octahedral complexes. This worksheet has 10 problems to solve.

Assist your class with understanding collisions as they apply the Law of Conservation of Momentum. Pupils measure the momentum before and after manipulation of two objects so that one strikes another in an inelastic collision. The lesson...

In this scientific method worksheet, students answer questions about the various steps of the scientific method. They distinguish between the variables in an experiment and between a hypothesis and a theory.
