lambda DNA Fingerprinting Simulation
Students perform restriction digests on DNA samples from four individuals, and then search for similarities between the individuals by running the restriction fragments on an electrophoresis gel.

Restriction Digest + DNA Comparison
High schoolers compare different DNA and run a gel electrophoresis. For this DNA lesson students complete a DNA activity that allows them to better understand its structure and function.
Curated OER
Carnivorous Plants
Students examine how carnivorous plants get their nutrients from animals. In this food web lesson students examine how the plants attract their prey and are given many onilne sources to research.

Forensic Files: A DNA Dilemma
Seventh-graders come in to science class to find a file on their desks detailing a crime to be solved! As a demonstration, you simulate the restriction of DNA samples and separate them by electrophoresis. From the gel, learners can...
Curated OER
Lactose & Lactase
Students examine the characteristics of lactose and lactase. In this enzyme instructional activity students study the lactose in milk and its rate of dissolution.
Curated OER
Milk Makes Me Sick
High schoolers 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...
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 lesson, 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
High schoolers 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.

Jeopardy
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?
Young scholars demonstrate the path of food in the body. In this biology lesson, 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.
Curated OER
Dinosaur and DNA Days
Biology stars extract DNA samples from beef thymus and then examine its properties. They use enzymes to digest the DNA samples, and then use electrophoresis to separate fragments. Finally, they discuss methods and principles of...

Activity #7 Apple Color Change
Students compare the different rates of reaction between an apple covered with vitamin C and an apple with no vitamin C. They compare the different rates of reaction between an apple placed in the sun and one not exposed to the sun. ...

Science Concept Maps
A collection of concept maps has some terms filled in and others left blank for young scientists to fill in. This library can provide you with many pop quizzes for all of your middle to high school science curriculum.
Curated OER
Determination of Phylogenetic Relationships Using Restriction Analysis
Students applied various mathematical analyses to interpret their data. By using the resulting DNA fragment patterns from several enzymes students established a possible evolutionary relationship among the mice.
Curated OER
COMPARISON OF FOUR-, SIX-, AND EIGHT-bp CUTS IN CALF THYMUS DNA
Students use this laboratory exercise, restriction enzymes to recognize a four-, six-, and eight-nucleotide sequence. Assuming that the four component nucleotides (A, C, T, G) are distributed randomly within a DNA molecule, then any...
