Learning Lesson: Salt 'n Lighter

Learners research energy and energy conservation and develop a lesson plan to teach what they have learned to younger students. In this energy conservation lesson plan, learners research energy and the need for conservation. Students...

This lesson will make an impact, especially on scientist-athletes who may have an interest in waterproof clothing! Acting as materials engineers, they work collaboratively on waterproofing pieces of cotton fabric. This challenge is...

Ahoy, matey! Here is an engineering expedition that mini mariners are sure to be swept away by! After reading a brief description and history of periscopes, they work in crews to construct one. Use this activity to enhance a lesson on...

Stop the raindrops from getting into the house! Eager engineers learn about roofing history and waterproofing by nanotechnology. They get into groups and work on designing a waterproof roof for a small model house. The accompanying...

Have small groups in your class construct working hygrometers as an example of the benefits of using sensors in engineering. This lesson can be used during a weather unit when covering humidity or in a STEM lesson as a preparation for...

Learners observe how to balance chemical equations and explore how to write formulas.  In this chemistry lesson students balance chemical equations and visualize the concept by observing an experiment using one of the equations. 

Every cell in the human body contains salt. In an interactive simulation, participants add different salts to water. Some dissolve completely and some are slightly soluble, remaining partially in precipitate form. The number of ions,...

Here is a recipe for a practical cross-curricular lesson! Cover unit conversions and ratios for math, the periodic table of elements for science, the difference between sodium and salt and its relation to high blood pressure for...

"What would you attempt to do if you knew you could not fail?" This question guides Regina Dugan's exploration of amazing achievements in science and engineering that push the boundary of impossibility. From robotic hummingbirds and...

Young chemists examine the effects of salt on the pH levels of solutions with the help of this instructional video. Taking a close look at reactions between three different salts and water, students learn to predict the change in pH...
