This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is...

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

Blast off! An engaging hands-on activity has pupils create rockets powered by Alka-Seltzer. They learn about the physics behind these rockets throughout the process.

Pupils often wonder how we know the distance to various stars. Starting with a thought experiment and progressing to a physical experiment, they determine the brightness and distance to various stars. The evaluation requires...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Your class is asked to use inverse operations to solve eleven equations for unknown variables or to rearrange formulas to highlight a quantity of interest. By using the same reasoning as solving one- and two-step equations, algebra...

Don't cast a great hands-on resource aside! Scholars learn about the process of casting by actually trying out an example. Plaster of Paris and cookie cutter molds help them complete the activity.

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...

Inquiry-based learning and investigations form the basis of a deep understanding of quadratic functions in a very thorough unit plan.  Learners develop recursive and closed methods for representing real-life situations,...

What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions. 

In this second lesson plan of the series, pupils learn to observe similarities and differences in photos of the sun and record them in a Venn diagram. Then, small groups practice the same skill on unique images before presenting...

What's in your water? And, why is water quality so important? Enhance your class's level of water appreciation through a lesson plan that demonstrates the necessity of water quality. Environmental enthusiasts explore the EPA's Clean...

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Sugar cubes, collide! Groups design protection systems using bubble wrap to protect sugar cubes from being destroyed by falling batteries in the STEM instructional activity. They consider how the experiment relates to collisions in...

Class members discover how mathematics can quantify the behavior of light waves with the fourth installment of a seven-part series that teaches future engineers about equations related to refraction, including the equation to...
