The second instructional activity on finding inverse matrices asks class members to look for a pattern in the inverse matrix and test it to see if it works for all matrices. The teacher leads a discussion to refine the process in...

Students 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 damage...

Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...

Learners observe water samples and measure the samples' water quality. Learners develop their own criteria for measuring water quality and test for temperature, acidity, oxygen levels, turbidity, conductance, sediment and hardness.

Students test Leonardo da Vinci's view of the human body by measuring various body parts using a tape measure. They create a data table and a scatter plot and then analyze and interpret the results using a graphing calculator.

Eleventh graders are introduced to the effect of gravity on plant growth. They describe the major processes and mechanisms by which plants grow, develop, and supply various products, including energy and nutrition, needed by other...

Sixth graders study the formation of convective storms and test mock hailstones. they graph and analyze collected data.

Young engineers are instructed to design and build their own solar water heaters. Then, they calculate the efficiency and cost and compare them to commercially available models. This is a full unit for pupils to apply their knowledge.

The size of a nanoparticle is difficult for pupils to grasp. A hands-on experiment is designed to give your classes perspective. Learners analyze different sports drinks for the content of electrolytes as an introduction to nanoscale....

Examine the application of the Pythagorean Theorem in problem-solving questions. Pupils apply the theorem to find lengths when given different scenarios. They finish the 17th installment in an 18-part series by applying the theorem...

What happens to light as it passes through a hole? This is the main question centered around the designing of a solar eclipse dynamic art piece that uses a solar eclipse and paper to create a pinhole projection of the art.

Students perform mathematical calculations to design safety device or enclosure to protect an egg as it is rolled down a ramp at increasing slopes.

Students examine the dangers of mountain climbing. After watching a video, they discuss the role of a German research team going into the Alps to predict who is going to adjust to the change in oxygen levels. They discover the...
