Math novices examine how math can help them in real-world situations. They listen to the book The Math Curse by Jon Scieszka, solve various word problems from the book, explore various math websites, write original math word problems,...

Sixth graders explore the concept of biodiversity.  In this biodiversity lesson, 6th graders discover a variety of planets and animals that live in forests, and how a rotting log benefits that environment.  Students also locate...

If you need a variety of questions for reactions and rate calculations, this resource is for you. Inspire your students to manipulate values and equations to fit the questions. The word problems are quite involved and require young...

Focusing on the quality of our water sources, these slides are full of information about the aspects of our soil and groundwater that may affect pollution.  The leaching of pollutants and their impact on health is explained. ...

This slide show progresses through a comprehensive review of the grounding principles of earth science. Get down and dirty with the details of fossil fuels! Help your geologists to have a rock solid understanding of the rock cycle. The...

How is iron is extracted from it ore and then combined with other materials to produce steel? That question is answered in the presentation. Also covered is how titanium and aluminum are used in manufacturing. This is a compact lesson...

Wow! This comprehensive collection of slides will walk your chemistry class through the foundation of chemical reactions, teach them to balance equations, differentiate types of reactions, and calculate stoichiometry problems. This...

Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect...

How well can your fifth graders work with decimals? What about subtracting decimals? Use this resource to practice these important skills. Sixteen problems help pupils subtract decimals to the hundredths place, while 10 problems at the...

Garbage, recycle, compost: Does it really matter where we put our trash once we are done? By making detailed observations over seven weeks, kids will see which materials break down naturally to become a healthy part of the soil, and...

Anytime you make concepts clear with role playing or hands-on experience, it's a win for the whole class. Ping-Pong balls are used to represent carbon in a carbon cycle role-play activity. In small groups, children first discuss what...

Young historians read and analyze a soldier's direct account of his participation in the battle of Gettysburg, as well as consider the overall strategy and tactics taken by the Union and Confederate troops.

Give your class a concrete example of exponential growth and decay using this hands-on activity. These Algebra II lessons allow for the exploration of exponential growth and decay models, as well as the discovery of the patterns of...

Having problems with proportions? Then solve these proportion problems with an exercise that asks learners to first individually solve a set of problems involving ratios and proportional reasoning. Groups then discuss provided...

Root for your pupils to learn about roots. Young mathematicians first review the meaning of squares and square roots. They then use this knowledge to simplify square roots of monomials with variables.

The power to solve exponential equations lies in the resource. Scholars first learn how to solve exponential equations. An activity matching cards with equations, intermediate steps, and solutions strengthens this skill.

Explore how resizing an object affects its area. The set of lessons challenges young mathematicians to design a mascot for electronic devices. These designs undergo resizing to determine how scale factors of dilation affect area.

Young entomologists construct three types of insect traps—pitfall, pollinator, and panel—before setting their traps out and observing what they caught. They then observe what types of insects the different traps attract.

Dead trees provide nutrients for the soil, food for animals, protection and a home for organisms, a seed-bed for new trees, and a place for nitrogen-fixing bacteria to live. In the activity, pupils collect decaying logs, expose them to a...

Not all structures take the shape of a polygon. The 21st lesson in a series of 29 shows young mathematicians they can create polygons out of composite shapes. Once they deconstruct the structures, they find the area of the composite figure.

Examine the nature of landfills through experimentation. Scholars build miniature landfills and monitor changes over a six-week period. Observations allow individuals to draw conclusions about the different types of trash and their...

My room isn't messy — it's a scientific experiment in entropy! Scholars investigate entropy, enthalpy, and spontaneity through a guided procedure and set of questions. The lesson connects the Second Law of Thermodynamics, energy...
