How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!

The "Bottled Bacteria" activity instructions are a bit unclear, but the remaining activities investigating limiting factors in ecosystems are well-written. Learners model the exosystem of a bear and a herd of deer. They set up a...

Explore how chemical processes reduce production waste. The 19th lesson in a 24-part series has learners explore the impact of green chemistry techniques on waste in production scenarios. They consider petrochemicals, bulk chemicals,...

Is qualitative or quantitative research more convincing when it comes to climate change? In the eighth lesson during this 21-part series, scholars begin by performing a quantitative analysis of deforestation and urbanization. Then, they...

Students identify the three realms of the Arctic Ocean, and describe the relationships between these realms. They identify major factors that limit primary productivity in the Arctic Ocean.

Wrap up the unit in one final design. Pairs use their knowledge of aviation to design new flying machines and record how their designs take into consideration the forces that act upon airplanes. The pupils determine whether their designs...

A set of guided notes walks your biology or environmental studies learners through the dynamics of ecosystems. They write short answers to questions about the energy budget, food webs, trophic levels, and biogeochemical cycles. One way...

Fifth graders identify all parts of an egg, and explore their importance to the life cycle of a chicken. Learners compare all sorts of birds and place them in categories based on what they look like. This five-day lesson effectively...

Use indirect measurements to monitor metabolic activity in plant cells. Scholars understand that cells with a higher metabolic rate have a higher concentration of catalase enzyme. They use this information to compare metabolic rates of...

When choosing what foods to eat, there are a lot of factors to consider. To help make the decision a little easier, young learners work in small groups developing short plays, stories, or advertisements that address the different issues...

Help your class understand the magnitude of the distance between Earth and Mars with an activity that asks small groups to use balloons to create scale models of the Earth, Moon, and Mars. Class members figure out the distances...

Students complete an experiment with Alka-Seltzer and reaction rates. They control the rate in which gases are allowed to escape. They test their predictions and observe what happens during the experiment.

What does your class know about GMOs? Are they savvy to selective breeding? Challenge young minds to engineer the greatest crop of all time using a hands-on genetics unit. Learners discover the good and bad details of selective breeding,...

In this chemistry worksheet, students select answers to 8 multiple choice questions from the drop down box. They identify the factors affecting rates of chemical reactions.

Ninth graders recognize differences in soil quality from one area to another. They describe the importance of organic matter in soil health and suggest ideas that help provide adequate food supplies for the world. The interview a person...

If your pupils think a catalyst is a list of their cats, then this might be the lesson plan for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...

It's time for a new life! Scholars learn what it means to give products new life by upcycling. They complete a crossword puzzle, read and discuss an article, and play a game about upcycling ideas.

How can we keep racism out of our society? Analyze the factors that lead to racism today and research previous scientific findings that impacted social policy. Your high school learners identify ways to prevent past mistakes from...

Clean up the environment with a lesson that focuses on replacing hazardous cleaning supplies with green, environmentally-friendly products. Using a dirty patch of surface as a control area, kids clean other parts of various surfaces...

Students investigate the importance of food surpluses to the historical development of urban ecosystems.

Students investigate the reaction rate of iodine and soluble starch. In this rates of chemical reactions lesson plan, students study the effects of varying concentrations of reactants and varying temperatures of reactants on the reaction...

Do great gardeners really have green thumbs—or just really great soil? Environmental scholars discover what makes Earth's soil and soil quality so important through research and experimentation. Learners also develop an understanding of...

Floating fragments of elodea can grow even without roots. Young scientists use eldoea plants to observe the oxygen production from photosynthesis. They study the difference between having access to high amounts of light and low amounts...

Young scholars examine the economic, health and environmental risks of being a one-crop country. They explain the risks of relying on one crop. They also identify the factors that resist change.
