Curated OER
Study of the Cell
Students draw a diagram to show the fluid mosaic model of a membrane. They explain how hydrophobic and hydrophilic properties help membranes hold their shape. They identify the functions of different cell membrane proteins as well.
Curated OER
Organs to Go...
Students explain the principles of experimental design and reinforce the steps of the scientific method. Each group of students create a "slush" type mixture to store a chicken liver.
Curated OER
Wolf Pack in a Bottle
Learners participate in an activity of a mock electrophoresis using paper chromatography to study DNA and genetic restriction mapping.
Curated OER
Investigating the Uses of Backyard Bacteria
Students discover that the answers to some of society's waste and clean-up problems may be no further than the soil beneath their feet. They perform a Gram stain on the colonies to determine some of their characteristics.
Curated OER
DNA Fingerprinting
Pupils experiment with chromatography as a technique which is similar to electrophoresis that scientists use to identify DNA samples.
Curated OER
Bioremediation
Students design and conduct investigations that illustrate the effect bioremediation has on organic matter and determine environmental applications. They, in groups, present their findings to the class.
Curated OER
SEPARATION OF A STARCH-GLUCOSE MIXTURE USING GEL FILTRATION
Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...
Curated OER
Separating a Starch-Glucose Mixture Using Gel Filtration
High schoolers experiment using the basic principles of gel filtration. They use the gel filtration technique for testing for the presence of specific substances. Students discover that starch is a larger molecule than glucose.
Curated OER
Cell Transformation in Tobacco Leaf Disks
Students review the basic principles of plant cell structure, tissue culture, sterile technique, and cell transformation. Next students complete a plant transformation experiment using whole plant material in order to view evidence of...
Howard Hughes Medical Institute
Hhmi: Biointeractive: The Immunology Lab
In this lab, students perform a virtual ELISA (enzyme-linked immunosorbent assay)to test whether a particular antibody is present in a blood sample. Students engage in key science practices, including experimental design and data...
Science Education Resource Center at Carleton College
Serc: How Enzymes Work
For this biology lab, students use pineapple juice as an enzyme, and jello as a substrate to illustrate an enzyme/substrate complex.
Science Education Resource Center at Carleton College
Serc: Investigating Characteristics of Enzymes & Factors That Affect Their Funct
By using inquiry skills, students will design and complete a lab investigation to gain an understanding of the concept of enzymes.
Howard Hughes Medical Institute
Hhmi: Biointeractive: Virtual Immunology Lab
This virtual laboratory demonstrates how an enzyme-linked immunosorbent assay (ELISA) is carried out and some of the key experimental problems that may be encountered. Students will learn about the assay procedure and the equipment and...
Lawrence Berkeley National Laboratory
Berkeley Lab: Did You Ever Wonder? Why People Age?
Students explore the shifting role of senescent cells throughout the lifespan of organisms. The article discusses cancer, Judy Campisi, and enzymes. The resource consists of pictures, quotes, and links to additional resources.
Khan Academy
Khan Academy: Units for Common Medical Lab Values
Comparing and contrasting the amount of elements and function (hormone or enzyme activity in lab values.
Concord Consortium
Concord Consortium: Molecular Workbench Showcase: Biotech
Simulations of common biotechnology techniques performed in a laboratory setting. Learn how to complete these techniques and what task they are used for in the lab.
Bio Topics
Bio Topics: The Action of Amylase on Starch
An experiment designed to show students how enzymes work. This experiment specifically investigates how amylase acts upon starch.

Science Alive: Changing the Starch in "Yams" to Sugar
This lab activity provides students with the experience of using their own enzymes to convert starch to sugar (a disaccharide called maltose), then testing to see if the conversion has taken place.
ClassFlow
Class Flow: Gel Electrophoresis & Restriction Mapping
[Free Registration/Login Required] Following basic lab techniques of modern molecular biology, analyze the gel electrophoresis results of a restriction enzyme digest of DNA by using a HindIII-generated standard curve. Then solve two...
