#### Forensic Sciences: A Crime Scene Investigation Unit

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...

Lesson Planet: Curated OER

#### Worm Your Way Out of This

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...

Lesson Planet: Curated OER

#### Rotting Away

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 about living organisms. After reading Log Cabin by Anne Schreiber,...

#### 2001 U.S. National Chemistry Olympiad - Local Section Exam

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...

Lesson Planet: Curated OER

#### Pizza Fractions

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.

Lesson Planet: Curated OER

#### Exothermic and Endothermic Reactions

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...

Lesson Planet: Curated OER

#### Microbes and Manure = Biofuel

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...

Lesson Planet: Curated OER

#### Investigating the Properties of Plastic and its Effects on the Environment

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....

Lesson Planet: Curated OER

#### Express an Area as an Expression by Decomposing Area (Example)

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,...

Lesson Planet: Curated OER

#### Getting the Dirt on Decomposition

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...

Lesson Planet: Curated OER

#### Perfectly Decomposed!

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...
