Students examine how photosynthetic rates can change by using different qualities of light. They practice using spectrophotometer and the scientific method to detect the absorbance values in light treatments.

Young scholars learn about the parts of a plant, and how plants live and grow.

First graders go on a leaf-hunting expedition around the schoolyard. They determine from which trees they fell using identification cards. Students read several books about leaves and apply their artistic skills by using the collected...

Students examine the carbon cycle while identifying its sources, sinks, and release agents. Using magazines and newspapers, groups of students design collages illustrating the carbon cycle. Finally, they write responses to several...

Student identify the characteristics of plants. Through hands-on demonstration, they create a model of plant parts. Students differentiate between the major divisions of the plant kingdom with a particular emphasis on the vascular and...

An educational instructional activity focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form. 

Explore soil, genetic traits, natural resources, and pollution in a series of lessons that focus on biodiversity. Kids complete experiments to learn more about the importance of varied genes and organisms in an ecosystem.

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

Young biologists trace the path of the sun's energy through marine ecosystems in the second part of this four-lesson series. Building on prior knowledge about producers, consumers, and decomposers students are introduced to the...

Jump into an exploration of marine ecosystems with the first lesson in this four-part series. After first learning about crustaceans, mollusks, and other forms of sea life, young marine biologists view a PowerPoint presentation that...

These lessons use a variety of methods and approaches to teach flowering plant biology which includes seed germination; plant growth and food production through photosynthesis; plant transpiration and respiration; sexual reproduction...

In this life cycle workbook, 5th graders examine plant and animal cells, classification of organisms, human biology, photosynthesis, and natural environments. 21 different activities make up the Life Cycle Workbook.

Second graders gain an understanding of how plants produce oxygen and that the oxygen we breathe comes from trees and plants. After a lecture/demo, 2nd graders discuss the ways plants produce oxygen and the detrimental effects of cutting...

Young scholars observe changes in a selected tree leaf near their homes during the fall. Twice each week students record changes in the leaf using words, pictures, and numbers.

Ninety-seven percent of scientists who study climate agree that human activity is warming the planet. Learners explore carbon dioxide as a greenhouse gas, a gas causing this warming, through a hands-on experiment. Once complete, they...

Students discuss photosynthesis. They explore and discuss surface tension, hydrogen bonding and capillary action with hands on experiments. They make journal entries and draw pictures of the different stages of the experiments.

Students examine the importance of submerged aquatic vegetation in the St. Mary River ecosystem. They identify different characteristics of common eelgrass and discuss water quality, photosynthesis, habitat, oxygen production.

Fourth graders realize that plants need light, water, and carbon dioxide to carry out photosynthesis. They participate in groups of 4 to plant (with materials provided) a test group of beans to compare to the control group, write a...

In this water worksheet, students determine the factors that effect the solubility of gases, calculate the percent concentration of solutions, and give the balanced chemical equation for photosynthesis. This worksheet has 18 short answer...

Students determine

An extensive investigation of the Earth's climate changes awaits your environmental science classes. This top-notch presentation begins by looking at the history of Earth's climate and then predicts the impact on each major terrestrial...

AP environmental science or college-level ecology classes will glean a tremendous amount of information on nutrient cycles from this detailed PowerPoint. It covers nutrient requirements, biogeochemcial cycles, decomposition rates, and...

Here is a well-designed science lesson that shows learners that everything that organisms do in ecosystems, including running, breathing, burrowing, growing, requires energy. After a thorough discussion of their own eating and drinking...
