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 lesson, 7th graders conduct an experiment to determine the variables that affect the flight of paper airplanes. They design an...

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...

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

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.

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....

Students solve equations by writing expressions. In this algebra instructional activity, students identify the different values for each variable. They use the navigator to see how to solve equations.

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

Students 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. Students utilize soaked seeds in a...

Students work together to design an experiment. They discover the origin of a family artifact. They analyze the data and discuss the results. They determine if the experiment is the best way to find out this type of information.

Students experiment to determine the effect of light on cyanobacteria movement. They graph the data of the experiment for further analysis. They watch a time-lapse video of cyanobacteria motility at a NASA website.

Help your class come up with a procedure for comparing the dissolving rates of colored candy coating in different temperatures of water. If you are placing importance on controlled variables with your class, make sure that they use equal...

Students explain the importance of having a control when setting up an experiment.

Learners experiment with point graphs. In this math instructional activity, students are divided into groups and perform an experiment to see how high a ball bounces, recording their results on a point graph. Learners then answer...

Learners develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

Sixth graders plan and conduct an experiment on food spoilage. They design the experiment, create a display, record and analyze data, and make inferences regarding the results of the experiment.
