First graders study plants and animals and how they depend on one another. They also study that plants give energy to animals and provide oxygen needed for life. Finally, 1st graders give examples of the roles plants and animals play...

Young scholars actively engage in the careful analysis of chromosome banding patterns and identify examples of inversion in homologous chromosomes.

Students test different sized marbles and how fast they can go. For this energy lesson plan, students test different sized marbles going down an incline. They predict which would have the most potential and kinetic energy. After the...

Students draw maps of counties that were important to the discovery of plate tectonic theory.  In this plate tectonics lesson students excavate constructed fossil sites from matching coastlines and discuss the possible explanations...

In this variables in experiments worksheet, students read about control variables and experimental variables before they respond to 15 graphic organizer and short answer questions.

Fourth graders complete an experiment on calculating speed.  For this speed calculation lesson students complete an activity in which they have dominoes fall as slow as possible. 

In this footprints learning exercise, students compare dinosaur prints and human prints. Students compare and draw different prints by answering 7 questions.

Students distinguish between walking, jogging and running trackways in humans. They analyze the phylogenetic progression of the leg position as described by pace width and angulation, comparing amphibians, reptiles and mammals. Research...

In this scientific inquiry worksheet, students match words to definitions and fill in the blanks for scientific inquiry. Students complete 9 problems total.

Sixth graders develop a reasonable hypothesis for a fictional science fair investigation. 'Raquel' is going to grow radishes and test for the best way to nourish them. They create a bar graph and write conclusions.

Students compare and contrast the size, composition and surface features of the nine planets of our solar system with the possible sizes and compositions of extra -solar planets.

Third graders participate in an activity to determine which tool will work the best to gather food. They create analogies about how the experiment relates to birds. They brainstorm about which adaptation helps or hurts the survival of an...

Learners calculate the diameter of planets and their relative distances.  In this space science lesson, students discover how small or big the planets are in comparison to each other. Learners use cross multiplying fractions to find...

Students investigate the tracking of viral diseases. They view experiments that compare the genome of the virus known to cause the disease from different areas. Students analyze how these scientists try to figure out the relationships...

Pupils analyze what's happening and interpret why it's happening as the season progresses.

Students calculate the relative thickness of limb bones in five different species. They relate this to the strength and functions of the limbs by comparing and contrasting the values calculated from the bone measurements. They work in...

Students investigate how selective forces like food, predation and diseases affect evolution. In this genetics lesson, students use red and white beans to simulate the effect of malaria on allele frequencies. They analyze data collected...

Students experiment to discover that salt water is denser than fresh water by creating color coded solutions. They examine how heavy rainstorms and high tides develop layers of different degrees of density.

Students design an experiment to discover how termites respond to their environment.

Students engage in an experiment for the scientific concept of diffusion of particles. There are instructions for classroom set up prior to conduction of the activity. Students sit in the classroom that is filled with the smell of...

Students explain what factors determine density. In this physics lesson, students hypothesize which objects are less dense. They cite the importance of density in everyday life.

Tenth graders grow two different bacteria cultures. They count the colonies, and then use graphing calculators to predict the number of colonies that are going to appear. Students answer questions from their worksheet after completing...

Students explain the basics of rocketry and explain the relationships between mass, acceleration, and thrust.

Students use the internet to research what life was like for Confederate and Union soldiers in a specific battle of interest to them. In groups, they complete a webquest on the battle in which one represents a Confederate soldier and the...
