Plants in Your Gas Tank: From Photosynthesis to Ethanol

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...

For this living environment worksheet, young scholars complete a crossword puzzle given 34 clues about the various species in the environment that produce, consume and decompose. Topics also include photosynthesis, respiration, glucose,...

Provide your class with the opportunity to view our carbon cycle close up. Young scientists research the cycle of oxygen as it completes the tasks of photosynthesis and respiration. They explore the importance of carbon in an ecosystem...

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

Provide learners with the tools to further understand nuclear energy and isotopes. Young chemists investigate the components of an atom's nucleus, use symbols to represent various isotope forms, and use the percent abundance of an atom's...

Non-vascular plants, like moss, are able to survive on photosynthesis. A video explains plant structure for both vascular and non-vascular plants. It includes the parts of each plant and adaptations to various environments such as the...

From stately oaks to towering pines, trees are the largest members of the plant kingdom that most people see. But how do trees get so big? Find out where the mass of a tree comes from with a short video. The narrator presents the topic...

Students are able to draw a diagram of the light reactions and briefly describe what is occurring throughout the process. They are able to explain where each reactant/product in the photosynthesis equation comes from/goes during the...

The topic of photosynthesis is a fundamental concept in biology, chemistry, and earth science. Educational studies have found that despite classroom presentations, most students retain their naive idea that a plant's mass is mostly...

Students gain an understanding of the parts of a plant, plant types and how they produce their own food from sunlight through photosynthesis. They also learn about transpiration, the process by which plants release moisture to the...
