Young scholars recognize dependent and independent variables in an experiment by practicing manipulation of variables; students practice designing experiments that contain the two types of variables.

Students study the variables that affect the Earth's albedo.  For this environmental data analysis lesson students interpret and graph information and calculate changes. 

Physical science juniors will enjoy this sensational enrichment on aerodynamics, especially if they are also sports fans! With a focus on physical features and behaviors, collaborative groups make observations on five different golf...

Graph and solve linear equations in two variables. The class relates the concepts of linear equations to the real world.

Is it easy to make snow? Scholars use critical thinking skills as they investigate the concept of polymers by making snow. The class tests several different variables and takes measurements over the course of several days. They then...

Young scholars predict and test different variables that would effect sugar cubes dissolving in water. In this dissolving lesson plan, students have 4 petri dishes with 4 different variations of sugar cubes and water. They predict which...

Middle schoolers examine the effects of variables. They view a video which introduces the concepts, take part in an internet-based activity, then engage in a hands-on activity which allows them to practice what they have been studying.

Investigate the relationship between independent and dependent variables. Individuals begin by identifying independent and dependent variables from different problem situations. Then, using specific guidelines, they create posters...

Define rays and half planes, including the concepts of boundary lines and prerequisite knowledge of coordinate planes. Given linear inequalities in one and two variables, your class will compare the differences. They will also graph...

Fifth graders plant and take care of a lima bean plant and make predictions on its growth.  In this science lesson, 5th graders chart their records and make conclusions about their experiment. 

Ninth graders conduct experiments to determine what affects the rate of a pendulum's swing. Working in small groups, they identify an independent variable to study and create an experiment to test their hypothesis. When tests are...

Seventh graders identify variables and controls in a paper airplane investigation. In this scientific method lesson, 7th graders conduct an experiment to determine the variables that affect the flight of paper airplanes. They design an...

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

The first in a six-lesson mini unit, all using M&Ms® candies, this physical science activity gets kids to observe a single piece and discover what happens when it is placed in a plate of water. The activity can be used to...

Provide young biologists with everything they need to excel in the study of lymphatics, the nervous system, hormones, cellular division, and more! Pupils utilize the workbook, complete with end-of-chapter assessment worksheets, to...

Andree Walker thought of everything when he wrote this resource. It includes a detailed list of materials and background information links for the teacher. In addition, it has procedures, a macroinvertebrate identification key, and tally...

Students solve equations by writing expressions. In this algebra lesson, students identify the different values for each variable. They use the navigator to see how to solve equations.

Students examine factors which affect a vortex and create model tornadoes. They identify variables, pose a testable question, and perform an experiment using the scientific method. After they collect their data, students write a complete...

While pupils design their own lab experiments, they will not form a new species. Scholars take their materials and design an experiment regarding reaction rates. 

Don't be shocked when your class has a blast making their own batteries! Science scholars examine a dry cell battery, then design and construct a wet cell battery. The activity guides them through the parts of a battery, the variables...

Help your class come up with a procedure for comparing the dissolving rates of colored candy coating in different temperatures of water. If you are placing importance on controlled variables with your class, make sure that they use equal...

Students explore viruses and how your body fights against them. In this viruses and variables activity students complete an activity with test tubes and try different variables to see what changes. 

Fifth graders recognize the need to follow the scientific method carefully and be aware of variables in experiments.  In this airplane lesson, 5th graders design and test an airplane, and complete a data sheet. Students retest five...

Students distinguish between scientific and everyday meanings of key words-theory, hypothesis, law, fact-and use in context. They recognize the variables that affect observation, data collection, and interpretation. They discover the...
