Mint candies are good for more than just one's breath. Using basic materials such as mint candies, straws, index cards, and Popsicle sticks, scholars create race cars that meet a given budget as well as design constraints. They perform...

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...

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 lesson goes...

Wiggle your way through lab day! Young zoologists observe and infer the effects of different stimuli on earthworms during an engaging lab from the K20 series. Lab partners set up four different controlled environments, then record how...

Guide learners through an experiment with a set of worksheets on the scientific method. Six steps prompt your class to ask questions, conduct research, form a hypothesis, test theories, analyze data, and report results.

Knowing the temperature coefficient allows for the calculation of voltage output at any temperature. Groups conduct an experiment to determine the effects of temperature on the power output of a solar panel. The teams alter the...

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...

As an introduction to the skills required for and responsibilities of driving, pre-teens and teens engage in a series of activities, chart their response times, and analyze how variables effect these reaction times. Class...

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....

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...

Demonstrate to your middle school science learners how chalk breaks down in a weak acid. Discuss what affects acidic rain might have on ecosystems. Lab groups then choose one of two questions: "How does acid precipitation affect an...

Use a hands-on approach to exploring the concepts of related rates in your AP Calculus class. Individuals explore the effect of the rate of change on a variable related to a variable they control. After analyzing the data they...

A link to a comprehensive macroinvertebrate guide gives you the information needed to prepare for this field study activity. Sample macroinvertebrates are collected from areas representing different environmental conditions. Junior...

Collaborative groups connect resistors and solar panels in series and measure electrical resistance, voltage, and current. The objective is to order 16 solar panels from strongest to weakest. They graph current-voltage and power curves...

How do sugar and salt affect celery's mass, width, and flexibility? Using simple household ingredients, young scientists will perform a controlled experiment to find out. The lab is scaffolded through a worksheet, but there are no other...
