Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a lesson that stresses the importance of controlling all variables. The second activity...

After taking in background information on teeth, marble, eggshell, and fluoride, chemistry aces design an experiment. Their goal is to demonstrate whether or not fluoride has a similar effect on marble or eggshell as it does on tooth...

Test the efficiency of your memory! Scholars test each other's memory as they explore factors that affect memory retrieval. Through experimental analysis, they discover there are different types of memory, which has an impact on the...

Never let them see you sweat ... unless you can't help it! Scholars design an experiment to determine the effects of stress on the body. They monitor sweat production under different conditions and relate the response to the function of...

Investigate experimental design through a hands-on exploration. A creative lesson allows learners to design an experiment to monitor the effects of alcohol on the C. elegans worm. After conducting the experiment, individuals analyze...

Scholars collect data from heating sand and water before forming testable hypotheses about why sand heats up faster. Afterward, they develop and run experiments to test their hypotheses.

Help your classes find the significance in this lesson! Learners analyze the probability of Diff values. They then determine if the difference is significant based on their probability of occurrence. 

It takes a lot of planning to achieve a random result! Learners compare results of random assignment, and conclude that random assignment allows results to be attributed to chance. They also realize the set of random means...

They say you can interpret statistics to say what you want them to. Teach your classes to recognize valid experimental results! Pupils analyze experiments and identify flaws in design or statistics. 

Communicating results is just as important as getting results! Learners create a poster to highlight their findings in the experiment conducted in the previous lesson in a 30-part series. The resource provides specific criteria and...

Challenge your classes to complete an experiment from beginning to end. Learners make their own hypotheses, collect and analyze their own data, and make their own conclusions. They are on their way to becoming statisticians! 

Pupils analyze group data to identify significant differences. They use simulation to create their own random assignment data for comparison. 

What are the chances? Teach your classes to answer this question using mathematics. The first part of a three-day lesson on determining significance differences in experimental data prompts learners to analyze the data by...

Students participate in an environmental clean-up activity. In this environmental lesson, students travel to a local beach. Working in small teams, students collect trash from the local beach. Returning to school, students sort the trash...

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...

In this lab design and lab skills worksheet, learners answer questions about experimental design including finding variables, determining controls, and graphing data. They answer questions about microscopy and label the parts of a...

Students discover how easy it is to accept oulandish claims by witnessing a fellow student show that they have a form of ESP but is secretly working with the teacher. This demonstrations uses skepticism as a starting point for...

In this experimental design worksheet, students answer four questions about an experiment done on shampoo. They answer questions about the independent and dependent variables and the materials and the hypothesis of the experiment.

High schoolers use a plastic sandwich bag containing a damp paper towel taped to a window as a model system to observe the germination and early growth of radish seeds. They are challenged to pose a question about seed germination and...

In this science worksheet, students look for the words that are related to the theme of the worksheet. They also work on the skills of spelling and word recognition.

Students are introduced to Scientific Inquiry and discover how to design an experiment that answers critical questions using butterflies as the topic. They design experiments that compare the number of species of butterflies in a vacant,...

Video program explains the difference between observation and experiment and the principles of experiment design. Lesson draws on real-life example of heart disease study and a double-blind experiment. [28:39]

This discussion of statistical experimental designs is presented in notes with examples added as needed.
