Do not let the class just sit and rot. Pupils learn how decomposition and nutrient recycling is important to an ecosystem. Groups design an experiment to determine how environmental conditions affect decomposition. They develop a poster...

When life gives you mold, make penicillin. Scholars design an inquiry experiment to determine what causes rotting and mold growth. It also covers decomposers and the important role they play for other living things. 

Mr. Bergman has been murdered and we need you to solve the crime! The cross-curricular unit covers 11 different types of forensic science and includes 17 activities. Scholars perform blood type analysis, blood spatter analysis, height...

How can you provide healthy soil for your garden? Study worms, bacteria, and other microorganisms in a lesson about decomposition and organic compost. After discussing what you know about worms and watching a video, watch what worms do...

What happens at the end of a plant's life cycle? Show kids the natural way that plants show that they're decomposing, as well as the importance of compost, with a lesson plan about living organisms. After reading Log Cabin by Anne...

Two laboratory problems are put forth for chemistry students. They are to plan and carry out an experiment that will answer each of the questions. The first asks them to investigate a relationship between the surface area of a potato and...

Two animated slides explain the decomposition reactions that occurs within a catalytic converter. An enthalpy diagram is displayed. Hess's Law is demonstrated. Finally, the analogy of football is used to explain Hess's Law. This clever...

Sixty multiple-choice chemistry questions make up this comprehensive exam used for the 2001 US National Chemistry Olympiad. Every topic that you would expect to approach in a general chemistry class is queried on. You could easily use...

Everyone loves pizza! Learners define fractions and use manipulatives to calculate fractions. Kids cut circles to represent various fractional parts of a pizza. Some accommodations are included. 

How can you tell the difference between endothermic and exothermic reactions? Chemistry scholars perform and observe two chemical reactions, measure the temperature throughout, then draw conclusions about changes in energy from their...

Waste not, want not! Science scholars explore manure as an alternative energy source through reading and experimentation. Groups construct their own biofuel digesters and observe the process of methane production. The teacher's guide...

Pore over the properties of plastic. Working through four different stations, pupils investigate some properties of plastic, including chemical decomposition, mechanical breakdown, density, and the ability to infiltrate the food chain....

Cut the area into two. Pupils see how to use algebraic expressions to find the area of a composite figure. The video breaks the figure into two rectangles and finds the missing lengths to find the area. After multiplying the dimensions,...

Sometimes science requires getting a little dirty. A hands-on lesson explores the idea of decomposition by building a compost structure. Using red worms and dirt, individuals build and collect data on the rate of decomposition. The STEM...

We all know someone who won't eat the banana with a brown spot, the grape with a dimple, and the apple with a bruise. Scholars use different fruits to explore what happens when fruits really start to decompose. They set up an experiment...

While well intentioned, human intervention sometimes has negative effects. Learners explore this and other environmental topics as they respond to four free response exam questions. Topics span from the implementation of bioelectric cars...

Several factors affect the rate of a chemical reaction including temperature, surface area, and concentration. Using an experimental approach, learners explore the effect concentration has on this rate while maintaining consistency with...

You'd be surprised what you can do with a string! The constraint is the length of string, and the task is to maximize area. Given a series of composite shapes, learners must create a formula for the maximum area for a specified...

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...

What has more energy than a room full of pupils after a fire drill? This lesson plan! Explore the changes in energy during different chemical reactions, discover why some reactions feel cold and others feel hot, and tackle the concept of...

Your heart may not be pumping, but there are still many chemical reactions that continue in your body. An installment of a video series on chemical reactions describes the decomposition process of our bodies after death. It pays...
