This lesson will explain the difference between independent and dependent variables. It is 3 of 4 in the series titled "Independent/Dependent Variables."

This lesson will explain the difference between a control group and variable groups, when using the scientific method. It is 4 of 4 in the series titled "Control and Variable Groups."

An explanation of how dependent and independent variables are used during experimentation.

This lesson will explain the difference between independent and dependent variables. It is 1 of 4 in the series titled "Independent/Dependent Variables."

In this activity, students will design, conduct, and report the outcome of an experiment in which they investigate some factor that affects the rate of reaction between baking soda and vinegar. The dynamic nature of the reaction, coupled...

For this structured inquiry, students will investigate a catapult system. Having previously explored and identified the variables of the catapult system (length of lever, mass of shot, angle of catapult), students will conduct controlled...

[Free Registration/Login may be required to access all resource tools.] Describe how the Renaissance period in history changed the approach to science. Identify the steps of the scientific method. Differentiate between the independent...

Students work as engineers and learn to conduct controlled experiments by changing one experimental variable at a time to study its effect on the experiment outcome. Specifically, they conduct experiments to determine the angular...

This curricular unit contains two lessons that let students actually do the work of scientists as they design their own experiments to answer questions they generate. In the first lesson and its associated activity, students conduct a...

Students conduct an experiment to determine how varying the composition of a construction material affects its strength. They make several adobe bricks with differing percentages of sand, soil, fibrous material and water. They test the...

Students study the physical properties of different fluids and investigate the relationship between the viscosities of liquid and how fast they flow through a confined area. Student groups conduct a brief experiment in which they...

In this lab activity students design an experiment controlling one variable with the goal of growing a plant taller than a control plant.
