Virtual Lab: Determining the pKa and Concentration Ratio of a Protein in Solution
It's pretty common to determine the dissociation constant for an acid or a base ... but, what about a protein? Challenge your class with a virtual lab designed to further develop their acid-base chemistry skills. Individuals determine...
Learning Games Lab
The pH Scale and Meter Calibration
What are the different ways to test for pH? First, scholars explore the pH scale and a common way to test for acidity and alkalinity. Then, they learn about the importance of pH in food safety and why variance in pH could potentially...
Curated OER
Soil Sample Lab
Students test the pH of soil samples they collected from the field trip. For this chemistry lesson, students differentiate acids and bases. They write a lab report about the experiment.

Virtual Lab: Determination of the pH Scale by the Method of Successive Dilutions
Where did the pH scale come from? Take a deeper look at a most important measure of ion concentration using a simulated physical determination. Young chemists prepare a series of dilutions after determining a dilution factor for the...
Curated OER
Protein Factory
Students discuss the steps of protein synthesis before acting out the process as a class. They are assigned specific roles and receive an instruction card and get materials listed in order to perform their role. Students switch roles...

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
The Structure of DNA
Students describe the structure of the double helix, explain how DNA copies itself, and recognize that the sequence of DNA is what makes each individual unique.
Howard Hughes Medical Institute
Virus Explorer
Most pupils know about the flu, HIV, and other viruses, but they don't know what each actually looks like. This interactive shows their relative size, structure, and allows for comparisons. It stresses the similarities and differences...
Curated OER
Visualizing a Human Gene with Its Introns & Exons
Students examine the entire DNA base sequence of the human adenosine deaminase gene after it is printed out from the source disk provided. The enormous length of a single gene as well as the immense difference in length between intron...
Curated OER
DNA Fingerprinting
Ninth graders investigate what restriction enzymes do, and explain how a DNA sample can link a suspect to a crime.
Curated OER
The ABC's of DNA
Students describe genetics as if they were explaining it to a young child. After reading an article, they discover new discoveries in the human genome project. Using the internet, they research a pair of genetic terms and develop a...
Curated OER
Lost Tribes of Israel
Students examine the issues involved with using DNA evidence in a courtroom trial. They read and discuss a case study of a particular trial, conduct research, and role-play a jury by reporting their verdict and discussing how they...
