Using a simple circuit with the battery representing the brain, future physiologists test to see which solutions conduct electrical "nerve impulses." Enlighten learners with plentiful information on electric signals in the nervous system...

It is positive that how one performs on the first test relates to their performance on the second test. The three-question assessment has class members read and analyze a scatter plot of test scores. They must determine whether...

Can you design the perfect chair? Scholars apply the engineering design process to design and build a prototype of a new type of chair from wires. They test their designs with a wooden artist model or stuffed animal.

Model hardness testing with a self-designed hardness test. Young scholars rate the hardness of different types of aspirin using the Vicker's Hardness scale. They then relate hardness to the solubility of each aspirin tablet.

Seventh graders create goals using two or more skills they have identified to help them improve academic achievement. They discuss the question: What choices do you make that affect your grades? Students listen to the story of Sam the...

Teach your class how to use descriptive statistics through a hands-on data collection activity. Pupils collect their own data, calculate test statistics, and interpret the results in context. They compare male and female results, looking...

Young scholars explore how and why local convective, possibly severe, storms develop. They examine how hailstones form and the conditions under which they form. They test mock hailstones of varying sizes to investigate the impact and...

Young scholars develop their understanding of the effects of invisible air pollutants. In this invisible air lesson, students complete experiments with a rubber band air test, a bean plant experiment and by exploring engineering roles...

A little too much strain could cause a lot of stress. Groups conduct a strength test on clay. Using books as weights, pupils measure the compression of clay columns and calculate the associated strain and stress. Teams record their...

Groups design the ultimate roller coaster by considering potential and kinetic energy. They test their designs using marbles and then go on to rate each group's design based on aesthetics, loop diameter, and cost.

Chunking information helps you remember that information longer. A hands-on activity tests this theory by having learners collect and analyze their own data. Following their conclusions, they conduct randomization simulations to...

Making inferences isn't an exact science. Using data about salaries, learners investigate the accuracy of their inferences. Their analyses includes simulations and randomization tests as well as population means.

Small groups use the engineering design process to build and test a vehicle capable of carrying 250 grams a distance of five meters. The design must allow for the storage of potential energy and turn it into motion,...

Future engineers test different alloys to determine the specific strength of each one. Based on the results, they make a recommendation to NASA on which alloy to use on engines for spacecraft.

Learners demonstrate the genetic principles of Heredity. They discover that each species has a unique Genetic fingerprint and that people can use "Genetic fingerprints" to solve a number of problems. They discuss examples of uses of DNA...

Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water...

Ramp up the engineering design process in your classroom with an activity that challenges teams to design, build, and test a small-scale portable wheelchair ramp. The class develops design requirements, and teams test their designs...

Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

During a macromolecule lab, young chemists perform multiple tests, including iodine starch tests, to determine if eight mystery foods contain lipids, sugars, or starches.

Two activities explore the concept of size, especially small sizes down to the nano. Scholars practice determining volume, mass, and density and calculate exponential increases and decreases. They then predict and test the effect of size...

Investigate the properties of rocks and minerals through a rockin' hands-on activity. Learners test rocks for various properties and, using a guide, attempt to identify different samples. They use various properties including hardness,...

Students study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur during low...

Students investigate the mechanics of an fMRI and the properties of neurons. In this biology lesson, students analyze the way the brain works by performing tests in the neurons in the brain. This is all done theoretically.

Challenge your class to use their understanding of the engineering design process to design and build a small-scale, off-road prototype for an assistive technology device. Teams select materials to build their scale models, and, using...
