Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

This clip picks up right where the Khan Academy's Photosynthesis video left off. Chemicals such as hydrogen and compounds such as NADPH are reviewed along with details including the stroma, thylakoid, lumen, and grana. See the parts of a...

One friend explains to another that plants combine water and carbon dioxide with the energy of the sun to produce sugar and oxygen. She mentions the roles of the roots, chloroplasts, and stomata in an engaging video that reviews how...

Middle schoolers obtain remote sensing data to compare and contrast global biomass data with global temperature data.

Two sequential parts to this lesson plan introduce your class to the electromagnetic spectrum, the ability to absorb radiant energy, and the pigments in leaves that are responsible for collecting sunlight to be used in the photosynthetic...

Students recognize the importance of plants as they perform an experiment involving photosynthesis. Students determine the optimum wavelength of light for photosynthesis by exposing plants to different colors of light, collecting data,...

AP biologists or college-level botanists consider in-depth details of the photosynthetic process. They examine the structures in a leaf and the roles that they play. They label neat and colorful diagrams of photosystems and electron...

There are many hidden colors in a leaf. A hands-on instructional activity from the series of Christa's Lost Lessons has pupils use chromatography to uncover beautiful hidden colors. They then connect their findings to the chlorophyll...

A little bit of this and a little bit of that. The final lesson of the 21-part unit assesses learners on each animal and plant system. The test covers the basics of each system and focuses on key vocabulary from the unit.

Trees are the star of a three-step unit celebrating Arbor Day. Step one takes an in-depth look into the structure of a tree, the process of photosynthesis, and the benefits of the leafy giants. Step two challenges scholars to create a...

Are weather troubles caused by El Nino? An installment of a larger series presents a five-part lesson on El Nino. First, scholars learn to read sea surface temperature maps. Then, they compare them to data on graphs before determining if...

All life requires energy ... and the connection between energy and plant life typically requires photosynthesis. Scholars explore photosynthesis in depth from ATP/ADP through the Calvin cycle. A helpful presentation highlights concepts...

In an evolutionary sense, plants seem to have it all figured out. But, do they really? The narrator of an engaging physics video that is part of a larger series questions the predominant color of plants in a short video. Content includes...

Magnesium is the eighth most abundant element in Earth's crust, the ninth most abundant element in the universe and the 11th most abundant in the human body. A video on chemical elements focuses on magnesium. It describes the properties,...

How would you fare as a plant? Learners watch a video in the ACS Reactions series that explains what would happen if humans could perform photosynthesis. They see that life would definitely be quite different!

Discover the scientific explanation of fall leaves! The lesson narrator describes the role of chlorophyll, glucose, and weather in the process of the color-changing process. He adds an overview of carotenoids and flavonoids to explain...

Earth appears blue and green now, but an interesting video covers a theory about when our planet was purple. We know the sun emits mostly green light, so why do most plants repel green light rather than absorbing it? Did purple microbes...

What are the differences between coniferous and deciduous trees? Supplement your tree lessons with a set of activities that has learners describing, naming, comparing, and reading about deciduous and coniferous trees. The activities are...

Nature provides density columns in the polar regions that provides food for many animals. Young scientists build their own density columns with water in order to answer analysis questions. Through a slideshow presentation, scholars...

Examine the role of chlorophyll in the process of photosynthesis. An interesting video lesson helps learners understand the efficiency of green chlorophyll as it creates energy for a plant. Although 99.9 percent of plants use green...

Discover the chemistry behind the color change in leaves. The lesson narrator describes how trees must recycle nutrients in the leaves before they fall off for the winter. The video breaks down the process and highlights the chemistry of...

Consider a question that baffles even scientists. Why are leaves green? The video lesson offers a theory that begins with the first aquatic plants. Learners consider alternative explanations as well.
