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...

In 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...

Make alterations in the variables of the original ZOOM Daredevil Ball Jump activity by heating or cooling the balls in the experiment. Predict how the balls' bounces will be affected by hot and cold, test the predictions and record the...

This site from Glencoe Publishing not only explains hypothesis but also tells how to design an experiment to test your hypothesis. Includes the difficult task of "Separating and controlling variables."

In this lesson, learners will learn about kites and gliders and how these models can help in understanding the concept of flight. Students will design and build their own balsa wood models and experiment with different control surfaces....

Given investigation scenarios and lab procedures, students will identify independent variables, dependent variables, constants, and control groups.

Students identify and control variables to design an experiment to see whether the temperature of a solvent affects the speed at which a solute dissolves.

Students are challenged to design a way to drop a raw egg from varying heights without letting the egg break. Creative thinking and evaluation of results are critical to the project.

[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...

An explanation of scientific research using variables and controls.

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...

In this unit, students can learn about the affects of water, soil, and sunlight on plant's growth while learning about the scientific process. Unit allows students to create a controlled experiment while studying plants.

Investigate the theory that including desert plants such as mesquite and cactus in a diet can help control obesity and diabetes. Design a scientific experiment that will test this hypothesis, using control variables, observation and...

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 young scholars design an experiment controlling one variable with the goal of growing a plant taller than a control plant.

Test the efficacy of different types of hand hygiene to stem the transmission of diseases by conducting an experiment using variables and a control group.
