How does the dirt get out of your drinking water? A hands-on activity introduces the use of flocculants to help clear solid particles out of water. The plan walks learners through the process of setting up an experiment that...

Over the course of 10 days, young scientists observe their cups of seed and soil—one that gets sun and water and one that gets no sun and only water. Then they reflect on the results of the experiment to determine if their hypothesis was...

Experimentally, come up with a study design. Learners hear about different types of study designs, observational studies, and experiments. They identify the subjects, response variable, treatment, and whether there was a cause and...

Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand. 

Caffeine affects your heart rate — or does it? Learners study experimental design while conducting their own experiment. They collect heart rate data after drinking a caffeinated beverage, create a box plot, and draw conclusions....

Up, up, and away! Take your classes on a physics adventure. Learners explore the concepts important for flight. They experiment with the Bernoulli Principle while learning the forces that act on airplanes in flight.

Adjust the melting time of ice without varying the temperature! Learners experiment with different materials to decide how the materials affect the rate an ice cube melts. They then connect their findings to the conductivity of each...

Ninth graders design and conduct an experiment. They evaluate other's experiments. Students describe relationships between biological systems and the environmental contaminants. They work as a team to solve a problem.

Middle schoolers study what an experiment is comprised of and how to be successful when doing an experiment.  In this experimental lesson plan students design their own experimental investigation and answer questions.

Students experiment bubbles. In this scientific method lesson, students identify variables used in proper experiment design. Students conduct experiments with different brands of dish-washing detergent to determine which brand makes the...

Break down the scientific method to get a better grasp on the proper way to use it. A short presentation walks through each step in the scientific method and the proper vocabulary associated with each. Scholars complete the worksheet to...

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

Middle school scientists learn the steps of the scientific method by watching this phenomenal film and by singing a karaoke song! They are introduced to making observations and hypotheses, determining variables, data collection, and...

Researchers think they have evidence of a new planet deep in our solar system that is the size of Neptune and orbits the sun far beyond Pluto. The orbit simulator shows the orbits of our well-known planets, as well as Pluto and the comet...

Fifth graders are introduced to the atlatl system and how to test and control variables. In groups, they use the Internet to research how the system has changed over time. They test various variables and record their results in a graph...

In this Scientific Method activity, students identify controls and variables given hypothetical situations taking place in Bikini Bottom. Students draw conclusions form the information they gathered in the experiments.

In this experimental design instructional activity, students identify the title, hypothesis, independent and dependent variables , the constants and the control for their experiment. They use a scoring guide to asses their progress.

Twelfth graders study the relationships of the 3 variables in Newton's Second Law. They design an experiment to test the relationships among the variables. Students work cooperatively with members of a team. They also analyze data to...

Second graders perform a variety of experiments to observe, form conclusions, and make inferences.  In this experiment lesson, 2nd graders experiment based on the result of a pre-assessment. Students share what they have learned.

How does food coloring work? Classes watch a demonstration showing liquids dissolving in liquids. In groups, they then explore the ability of other liquids to dissolve in water (alcohol, mineral oil, and corn syrup) by setting up and...

Students investigate seed germination. In this lesson on scientific prediction, students conduct a scientific experiment using oat seeds.

Students investigate the problem of osmosis by conducting an experiment. They use eggs with the shells dissolved to tell whether fluid can move across the membranes. The experiment provides high interest for all kinds of students to keep...

Young scholars experiment with graphing. In this graphing introduction lesson, students complete four activities: 1) a bar graph based on class birthdays 2) an estimation graph of the raisins in raisin bread 3) another estimation example...

Students experiment with solutions.  In this mixtures and solutions science activity, students work in groups of three to perform an experiment. Students place a sugar cube in three glasses, and observe and record the different...
