Digestion and Nutrition
In this digestion worksheet, students will match 12 terms associated with the digestive system to their correct definition. The vocabulary words review the digestive system organs and their functions.
Curated OER
Lactose & Lactase
Students examine the characteristics of lactose and lactase. In this enzyme lesson students study the lactose in milk and its rate of dissolution.
Curated OER
Milk Makes Me Sick
Students experiment with lactase to find out how milk sugar is broken down in the body. In this enzyme lesson, students use glucose strips to investigate the breakdown of lactose into glucose and galactose for milk digestion in the human...
Curated OER
Chemical Energy
In this science worksheet, students read about enzymes and nutrition. Students also answer 2 comprehension questions about the reading.
Curated OER
From One End to the Other
Seventh graders trace a piece of food through the alimentary canal and differentiate between mechanical and chemical digestion in several different hands-on activities related to digestion.
Curated OER
Yum - Yum!! - The Digestion Lesson
Students explore the various components of the digestive system and learn about both the physical and chemical processes that work together to break down food into absorbable molecules.
Curated OER
Breaking It Down
Seventh graders explain the mechanism of digestion. In this biology activity, 7th graders perform an iodine test to check for the presence of starch. They discuss how energy travels through the food chain.

Got Lactase? The Co-Evolution of Genes and Culture
Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...
Curated OER
Gel Electrophoresis
Young scholars conduct a variety of experiments to explore gel electrophoresis. In this biology lesson, explain how this process separate DNA and RNA. They discuss the practical applications of this method.

Learners played a game of Jeopardy where there was five categories with five questions each in order to assess the retention of concepts taught over the semester. The categories included: Graphing/Summarizing/ Scientific Method, Gravity,...
Curated OER
What's on Your Plate?
Students demonstrate the path of food in the body. In this biology lesson plan, students conduct an experiment to determine how large the the digestive system is. They name the different organs involved in the digestive process.
Curated OER
Lactose Intolerance
Students are taught how enzymes enable chemical reactions to occur a body temperature and how the lack of enzymes in the body can cause problems in the break-down and absorpion of nutrients. They match up different enzymes with the...
Curated OER
There's Always Room For Jell-O
Students explore the breakdown of proteins. They cut wells in Jell-O and observe as the detergent digests the Jell-O. Students record their observations and take measurements.
Curated OER
From One End to the Other
Seventh graders become more familiar with how our food is broken down mechanically and chemically. They also trace the food through the alimentary canal.
