Students evaluate a hypothetical experimental design and attempt to improve upon it. In this scientific method lesson, students are presented with an experiment and are instructed to determine its flaws. They conduct their own...

Students explore the concepts that enable them to design and conduct sound scientific experiments. They critique a faulty experiment and become familiar with some of the criteria of a good experiment. They conduct their own experiment.

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

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

Students are able to name one kind of harmful bacteria and why it hurts us and also name one kind of helpful bacteria and how we use it. They describe the process of growing bacterial cultures in a lab. Students create a reasonable...

Fourth graders make a detailed observations about non-native and native grasses. They define reasonable policies that they expect to follow while working in the CRWA. Students list, in small groups, two treatments that have been used in...

Time to experiment with mathematics! Learners study experimental design and how randomization applies. They emphasize the difference between random selection and random assignment and how both are important to the validation of the...

In this experiment worksheet, students give examples of independent, dependent, and controlled variables. This worksheet is a graphic organizer.

The scientific method keeps you from believing only what you want to believe — it expands your mind. The lesson introduces the eight steps in the scientific process and how to design an experiment to biology scholars. Live insects...

Students design an experiment to change the motion of a rolling marble. In this designing an experiment lesson plan, students form a research question, they develop a hypothesis and they design an experiment using a graphic organizer to...

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. 

Students 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 will...

Looking for authentic hands-on nutritional experiments? High schoolers will perform experiments to test for the presence of vitamin C in several solutions as well as the effect of caffeine on Daphnia. They will also consider the...

Here is an engaging lesson on solving equations with two variables. Have the class rewrite linear equations in the slope intercept form, y=mx + b. They graph the lines using the slope and y-intercepts.

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.

Many variables impact your body mass, not just diet and exercise. Scholars collect and study data about body mass to better understand the complexity of a sensitive topic. They learn about leptin deficiency, the hypothalamus, and more.

Putting glow sticks in the freezer makes them last longer, but why is that? Lesson focuses on how temperature impacts the rate of a chemical reaction. It begins with a teacher demonstration, then scholars design their own experiments...

Students identify and apply the scientific method through an experiment with popcorn. Then they identify what independent, dependent, and control variables are and create a list of different variables that affect popcorn popping....

High schoolers 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.

You've heard of farm to table ... but what about farm in classroom? Junior agriculturalists embark upon a two-week journey into the science of growing things. Based upon the classic terrarium in a two-liter experiment, the activity goes...

Students conduct experiments to discover the various ratios of oil to popcorn kernels. They determine which amount of oil produced the most popped kernels.

In this motion worksheet, students design an experiment to investigate motion. They form a question, they develop a hypothesis, they design an experiment and then answer 4 questions about their experiment.

Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

Learners explore botany by participating in a seed experiment. In this plant nutrition lesson, students define several science experiment vocabulary terms like observation, treatment, and replicate. Learners utilize soaked seeds in a...
