Third graders complete a diagram of the revolution of the earth around the sun and write a one paragraph explanation of the factors that cause seasons.

Fourth graders explore the earth's revolution around the sun and the changes in weather that follow this motion.

Students create and conduct various experiments to determine the origin of a family artifact, and then determine whether their results were successful. Students summarize their results and evaluate whether their hypotheses were correct.

Fifth graders test the shelters that were built in a prior activity. They determine the level of durability and water resistance of these shelters through a scientific investigation.

Ninth graders explore the concepts of motion, velocity and acceleration through graphing their own movement using LoggerPro. They become more familiar with the computer technology. Students explore graphing in real time and graph on...

Students evaluate the importance of hormones in living things. In this biology lesson, students experiment on carrots to differentiate how humans and plants reproduce. They collect data from experiment to answer analysis questions.

Students analyze different experiments to determine independent variables, dependent variables and control groups.

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...

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

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...

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.

Lesson plan with mulitmedia links in which learners identify and control variables to help design a solubility test for different liquids in water.

[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...

Conduct an investigation collaboratively on the effect of force applied on an object to produce data to serve as the basis for evidence, by using fair tests in which variables are controlled and the number of trials are considered.

An easy to do activity that investigates the basic principles behind chemical bonding. The activity is written in lesson plan format that meets NSES standards.

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.
