Wave goodbye to the same old demonstrations for alternative energy sources, and wave hello to this one investigating ocean waves! Using a water bottle to create an oscillating water column, learners see and possibly hear how the...

Amateurs of alternative energy build a mini parabolic-trough solar energy collector and use it to heat water. Temperature is recorded over a three-minute period and the data is graphed and analyzed. Note that in order to paint aquarium...

This demonstration of solar ponds can be used in an earth, environmental, or physical science setting. Lab groups set up a solar pond and model how it is able, due to a salt concentration gradient, to maintain heat for future use. 

This lesson plan begins with a review of linear functions and segues nicely over its fifteen examples and problems into a deep study of exponential functions. Linear and exponential growth are compared in an investment task. Data tables...

Your algebra learners will enjoy the real-life application of the three tasks presented here. They complete a table and a graph comparing the two options presented. One option is linear, while the other is exponential. After coming up...

A little bit complicated, but a whole lot of fun. Show your class an episode of the British television game show Just a Minute. After an explanation of the rules (no repetition, hesitation, or deviation) groups develop topics, based on...

Skeeters are used to model linear and exponential population growth in a wonderfully organized lesson plan including teachers' and students' notes, an assignment, graphs, tables, and equations. Filled with constant deep-reaching...

Take a walk through time, 1852 to 2005, following the mathematical history, development, and solution of the Four-Color Theorem. Learners take on the role of cartographers to study a United States map that is to be...

This is a fantastic collection of a wide variety of rubrics for writing, listening, and speaking! The resource contains over 14 rubrics for assessing such items as a summary, autobiographical sketch and narrative, speech, oral...

How to paraphrase, when to paraphrase, and the difference between paraphrasing and quoting is the focus of a 23-slide, color-coded presentation that not only instructs viewers but also asks them to demonstrate their understanding of the...

With so much talent in the classroom, do your musicians and athletes have related interests? This problem has your learners taking data from their classmates to decide whether there is an association between the two activities. The...

Do big bodies make big brains? Let your learners decide whether there is an association between body weight and brain weight by putting the data from different animals into a scatterplot. They can remove any outliers and then make a line...

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

Practice with unit rates, proportions, and ratios when Carlos purchases an amount of bananas. Learners must interpret a graph to decide whether points on the same line represent similar proportional relationships. Use with lesson plans...

All the tools (and directions) you’ll need  to build an essay are included in a resource designed for learners and educators. The packet can be given to class members or divided into sections and used as part of a series of lesson...

"The Gettysburg Address" is the basis of a series of activities that not only model for learners how to conduct a close reading of a text, but also how a close reading can help them comprehend a difficult text. The detailed, step-by-step...

Turtles are not known to be speedy movers, but have you ever tried to get them to move in a specific direction? How about getting them to move in a perfect circle? With this app, young computer programmers have to be on their toes to...

Plankton: so much more than just a SpongeBob character. Three different activities have kids looking at both phytoplankton and zooplankton in pictures, as well as collecting their own samples (depending on your access to a saltwater...

Metaphors, the definition of, types of, and examples of, are the subject of a short video that models for viewers this grand poobah of literary terms. Colorful images and animations are used to illustrate the connections between...

Illusions and allusions certainly sound similar but there is a world of difference in their meanings. The narrator of this short video distinguishes between these terms, defines them, and offers examples that are sure to engage viewers....

The problem seems simple: find the area of the equilateral triangle whose sides are each length 1. In fact, this same problem is solved in 8th grade, addressing a different Common Core standard, using the formula for area of a triangle...

Mixture problems are a classic in first-year algebra. Unfortunately, many learners approach them in a formulaic fashion and don't truly understand the meaning of the algebraic expressions they are using. Here, the questions are not the...

Sometimes people who seem to lead what would be considered an ordinary life do extraordinary things. Such was the case with Oseola McCarty, who donated a large sum of money for a university scholarship fund in her name. Oseala lived her...

Build up from the previous activity where your learners charted the population growth and decay of a fish pond with M&Ms®. Have them look at the data from that activity and create a Now-Next, or recursive equations, to predict the...
