Lessons in this Unit
This lesson provides an overview of the definition of photosynthesis as well as its equation. The photosynthesis process is broken down into 3 main stages for ease of student comprehension. Students have to synthesize the information and use their knowledge and creativity to create a graphic organizer of the photosynthesis process.

In this lesson students will understand all living organisms contain enzymes. These enzymes exist throughout the cell and inside organelles that control the rate of chemical reactions (metabolism). Enzymes, biological catalysts, are proteins that are specific for the reactions they catalyze and without this "key" many biological processes cannot take place.

In this lesson, the students will explore the differences and similarities between diffusion and osmosis. They will also learn about concentration gradients in reference to solutes and solvents and the different types of solutions.

In this lesson students will learn the importance of cellular respiration, specifically aerobic respiration and anaerobic respiration. Included are two activities that demonstrate aerobic respiration in cells.

This lesson helps students understand that nearly all the energy in a living system comes from the sun. Students then trace how that energy flows through an ecosystem from autotrophs to heterotrophs.

Students will engage in an activity that allows them to see first-hand the process of fermentation by monitoring carbon dioxide accumulation. This this lesson should follow lecture or a lesson on photosynthesis and respiration.

This is a quick (35 minute) activity used after students have been introduced to the functions of cell organelles. This lesson also includes a very short (10 slide) power point presentation that can be used prior to the activity.
In this lesson, students will use analogies to compare the function a dairy farm to the function of a cell. Students will explore different parts of the dairy and make connections to how the parts are similar to the cell organelles. Students will be drawn into this lesson by playing a game called, “What am I and what do I do?” Next, student will be creating a dairy farm and labeling the farm parts with cell organelles.

In this lesson, students will be able to put their knowledge of the photosynthesis equation to work. Students will discover the importance of light and the color of light in the production of starch (food for the plant). During this lesson, students will get a chance to work with plants and spend some time in the greenhouse.
