Consider biomass as an alternative energy source with this PowerPoint. Environmental science pupils discover the potential of converting gases produced by landfills into useful energy. They compare and contrast environmental and economic...

Could the history of bread really be interesting? Yes, it could! An informational text gives scholars wheat production background from 8,000 years ago, discussing different types of bread and the current industry in Oklahoma. Learners...

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

Four polygons each have a fraction with unlike denominators printed on them. Creative math minds select several shapes to create a design with and then write and solve a math problem involving the addition of all of the fractions...

Teams of six to eight players imagine that they are driving in a vehicle and collect balls that represent carbon dioxide emissions based on their different activities. "Greenhouse Gas Guzzler" cards tell teams how many balls to collect...

Discover the interesting world of maritime archaeology and explorations under the sea with this nice set of worksheets, which cover such topics as search tools and techniques of underwater archaeology, carbon dating,...

Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-lesson series supports children with learning how to measure the area of squares, rectangles, and other...

How can you tell if fractions have equal value? Use various collaborative activities to demonstrate the ways to determine whether or not fractions are equivalent.

This trigonometry textbook takes the learner from a basic understanding of angles and triangles through the use of polar coordinates on the complex plane. Written by a mathematician-engineer, examples and problems here are used to...

Pupils design a fence for a backyard pool. Scholars develop a fence design based on given constraints, determine the amount of material they need, and calculate the cost of the project. 

If members of your class wonder where they can use the math they learn in middle school, let them discover the answer. Learners apply geometry concepts of scale and measure to calculate the costs of framing a house addition.

Looking for an insect unit that addresses multiple skill strategies? Young entomologists explore multiple life cycles of insects that go through metamorphosis. The brainteasers and mobile activity spark learner interest before guiding...

Ground-truthing ... is it even a word? The last installment of a five-part series analyzes how scientists collect sea surface temperature data. Scholars use government websites to compare temperature data collected directly from buoys...

Utilize the lesson on utilization. The second installment of a nine-part technology/engineering series teaches scholars about the flow of a balanced assembly line and the definition of utilization. Videos, activities, and simulations...
