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.

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...

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...

In this coal formation worksheet, students read and informational sheet about coal formation. Students are given 5 short-answer questions regarding what they've read.

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...

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...

In this reactions worksheet, students complete the given reactions by writing the products. Students do examples of composition, decomposition, single replacement, double replacement, and combustion reactions. This worksheet has 54...

Not all chemical reactions happen at the same rate because some, like explosions, occur quickly and some, like rusting, occur over time. Here, learners explore chemical reactions and their rates in the 16th lesson of 36. Through readings...

Students play a board game with provided cards which help them realize that limiting factors may restrict an organism in its development and productivity and direct evolutionary pathways.

Students observe biotic and abiotic things participating in an observational walk outside the school. They create a collage using pictures of biotic and abiotic items.

Second in a series of five lessons, this lesson encourages preteens to consider cities as urban ecosystems. First, they keep a food diary for a few days. They visit the Natrional Agricultural Statistics Service website for current data...

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

Future public health officials or agriculturists read an article and answer questions concerning the Japanese regulations for pesticide exposure. They compare the maximum residue limit for two, 4-D of Japan with other countries. This is...

For this kinetics worksheet, students review activation energy, rate of reaction, and reaction mechanisms. This worksheet has 13 multiple choice questions.

How is a movie theater like a desert biome? Compare systems to ecosystems with a set of activities that focuses on accessing multiple intelligences and building upon knowledge. As learners discuss the ways elements of an ecosystem depend...

Tree rings are slightly thicker on the south side of the tree because it receives more sunlight. Part two in a series of five lessons helps learners analyze tree rings to determine the environmental conditions that caused size...

Here is a comprehensive and well-written lesson plan that results in learners building a standard wind turbine. Once built, teens can design a variety of experiments to test different factors. This activity is a noble undertaking that...

Tenth graders research locations of biomes and their barriers. In this biomes lesson, 10th graders examine location, environmental conditions, and species of plants and animals that live in the biome. Students take notes and create a...

Students discuss advertisements and techniques they have discovered. They read an article about the science of selling and create an advertisement of their own to sell a book. They record people's reactions to their advertisement and...
