First there was pi and now there's e. A discovery-based lesson plan helps learners find a pattern in compound interest as the compounding period changes. Their investigation results in the discovery of the number e. The lesson plan is...

Don't let your class's heart rates rise as you introduce them to differentiation ... an inquiry-based lesson helps them keep it in check! The second lesson in a three-part series asks learners to analyze the rate of change of different...

From derivatives to antiderivatives and back again. Building on the second lesson of the three-part series covering functions, learners explore the concept of an antiderivative. They connect the concept to the graph of the function and...

Build a solid foundation on which to develop future concepts. Through a guided exploration, learners compare and contrast the characteristics of points, lines, planes, rays, and segments. They measure lengths and practice notation for...

The world is full of patterns. Help learners quantify those patterns with mathematical representations. The first Algebra lesson in a compilation of four uses a series of activities to build the concept of patterns using multiple...

Develop conceptual knowledge of a quadratic equation and its solutions in your classes. The third algebra lesson in a series of four introduces learners to solving quadratic equations slowly. The first activity explores the zero product...

Do your pupils truly understand inverse operations, or is their understanding a little backward? Scholars learn the meaning of an equation in the second lesson of a four-part Algebra series. A series of activities begins with an...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Learners calculate the pixel density of a specific cell phone using the concept of similarity. They use information from the cell phone's website to make their calculations and then compare their results to the posted information.

Puzzle your way through to a new understanding of area. Scholars learn about the area of polygons through equidecomposability, the idea that polygons that can be decomposed into the same set of pieces have the same area. By using...

Don't assume your pupils understand assumptions. A teacher resource provides valuable information on inferences, assumptions, and conditions, and how scholars tend to overlook these aspects. It focuses on regression analysis, statistical...

Teenage brains are different! Understanding that the teenage brain is still developing and thus more impacted by substance abuse is the key concept in a three-lesson high school health unit. Participants learn about how the brain and...

Dive into the political breach with pupils and explore the reasons for political polarization. Using clips from C-SPAN that include discussions from reporters and scholars, class members consider what is causing the political fault lines...

Many changes happen to a pregnant woman's body, mind, and emotions in these nine months. Discover and talk about these many changes. The class may know some of these things, but some things they might not know about, or they don't know...

Students review basic Latin terms pertaining to Roman gladitorial games, print out pictures of gladiators from Internet, share photos with classmates, choose gladiator to research, and prepare in depth visual and oral presentation about...

Students explore DNA. They work in groups and mix prepared detergent/ salt solution, meat tenderizer solution, Fleischman's yeast and water to extract DNA from yeast. Observations are recorded.

Young scholars, working in small groups construct scale models of the planets and solar system. They examine images of Mars and discuss what might have caused the features. They record facts about their planetary research in their...

Listening is a skill. This lesson will provide your pupils with clear guidelines for what to do when someone else is speaking. Whether you ask them to note key words in a talk, to prepare two questions about the presentation, or to note...

A happy discovery occurred in Arkansas in 2004: a woodpecker, believed to be extinct since the 1940s, reappeared! Or did it? Middle to high school ecologists examine scientific evidence and use critical-thinking skills to determine...

Young scientists gain a better understanding of space, the solar system and its vastness by creating a scale model. Students first need to calculate the distance between each of the nine planets according to the size of their scale. This...

Students are given the unique opportunity to see the contrast between parts of a leaf that have photosynthesized and parts of the leaf that have not. This visual image helps students see the results of this biological process. At the...

Quadrilaterals can be quirky! Fourth graders use geoboards and bands to create four-sided figures. They analyze the attributes such as angle size and presence of parallel sides. As a result they learn to differentiate among...

Learners classify and compare plants using specific information, observations, and numbers. In this mathematical inquiry lesson, students use plant characteristics to describe, compare, and classify them. They attempt to develop a system...

Young scholars become aware of the effects of tides on the Earth's rotation. In this tides lesson, students calculate the number of seconds lost over various periods of time.
