Students play a game in which points are assigned to daily activities which require fossil fuels or electricity. They compare the impact their energy and transportation choices have in everyday life.

Learners demonstrate how water flows by building a human watershed using themselves. In this ecology lesson, students compare and contrast point-source and non-point source pollution. They write what they have learned from this activity...

Students investigate the transmission of light energy. In this light energy lesson, students observe bubbles using different colored filters and record their observations. They also look at a light source through various materials and...

Students investigate what a calorie is and how and why we measure them. They conduct an experiment to compare the calories of a peanut and a mini-marshmallow, and explain and discuss how calories are directly related to the amount of...

Students brainstorm ways they can reduce their energy consumption and then create New Year's Resolutions with their families to put these conservation plans into action.

Students explore alternative energy sources. For this environmental lesson, students discuss alternative energy sources and construct a plan to incorporate an alternative home technology into a bedroom. Students build a model of their...

Students identify the properties of light from the sun. In groups, they participate in experiments with solar collectors, cookers and calculators to determine which one harnesses the most energy. They record their observations and...

Sixth graders list the different forms of energy. In this physics lesson, 6th graders identify what form of energy a certain object possess. They explain the law of conservation of energy.

Careful, that light bulb is hot! Compare heat and light energy using a simple light bulb. The exercise addresses energy conservation and presents actual calculations to determine the most cost-effective light bulb.

Rarely do you find resources that reach high school astronomy learners. Here is something at their level! The physics of flyby missions is explained via several examples. Landing, penetrating, and roving spacecraft are examined. Diagrams...

Many young people act globally by reducing, reusing, and recycling, Now they take it to the next level by upcycling. Middle schoolers design a proposal to eliminate waste by exploring the new material cycle and applying...

Students determine crude oil can be separated into useful fractions by a process of fractional distillation. They write a balanced equation for the reaction between a hydrocarbon and oxygen.

In this glow-in-the-dark worksheet, students read about substances that phosphor and their characteristics. Students also read about photo luminescence and glow-in-the-dark toys. They answer 6 questions about the light emitted by...

Students observe the colors found in the flame of a burning candle and examine the basic concepts of matter and energy. Students apply this information to the color's of starts and the temperature of the stars photosphere. Students...

This exam covers every topic in a typical first-year biology course. A wide variety of question styles gives high schoolers every opportunity to show what they know. Why start from scratch when a comprehensive final exam is easily...

Emerging ecologists need a full understanding of life, from the inner workings of a cell to the complex relationships among organisms. This examination is meant to assess high schoolers after an entire year of courses on the living...

Assist your high school class with researching and applying the principles of gravity so they may further understand why Einstein is so widely recognized, even today. Individuals compare and contrast two different models that demonstrate...

Bubble, bubble, boil and trouble! What causes common substances like baking soda and vinegar to react the way they do? Welcome your junior chemists to the wonders of acid-base chemistry using a comprehensive and fun...

In collaborative groups, emerging engineers or environmental scientists plan and construct a water wheel or watermill that rotates for a total of three minutes. Everything you need to carry out this lesson is included: objectives,...

Enzymes play a role in almost every function in the human body. Scholars explore three variables related to the use of enzymes. They observe a catalase reaction, experiment with substrates, and examine reactions rates. 

Some of the CO2 emitted by burning fossil fuels is removed from the atmosphere by natural sinks, such as the ocean. The fifth engaging lesson in the series of 21 examines the CO2 data from three very different locations. It then makes a...

Around 93 percent of the reefs on Australia's Great Barrier Reef have been bleached, and almost one quarter of them are now dead. Scholars research the sea temperatures, especially around the areas with coral reefs, to make connections...

Desert regions are hotter for multiple reasons; the lack of vegetation causes the sun's heat to go straight into the surface and the lack of moisture means none of the heat is being transferred into evaporation. This concept, and other...

When measuring the circumference of a tree, does it matter how high you place the measuring tape? Most scholars have never considered this question, but scientists know that measurement techniques must be standardized. The 13th lesson in...
