Students demonstrate the use of a knurling tool. For this machine shop technique lesson, students will demonstrate safety as they properly use the knurling tool to create a diamond knurl and a straight knurl on a cylindrical piece of...

Students discover the biases between the two genders by comparing males and females in different species.  In this gender identity lesson, students research National Geographic Magazine and view videos demonstrating the differences...

Students watch animal videos to identify and compare the male/female roles of different species of animals. They draw conclusions and compare those roles to those of humans. They discuss how the human male/female roles have changed...

Scholars explore the procedure for bacteria sampling in a virtual lab by first walking through a detailed step-by-step procedure of preparing the samples of raw milk and pasteurized milk, growing the bacteria, and comparing results....

Scholars use a lab simulation to test contaminated yogurt for bacteria by gram staining. They learn proper lab procedures for handling bacteria and for sterilizing equipment, and then walk through the process on their own to try gram...

Food storage matters! Scholars learn how the amount of water in corn can affect its rate of spoilage. They create a control group, then test three corn samples stored in three different locations for water activity. As a result of the...

Teach the class how to use a microscope to identify bacteria in food. Scholars explore the different parts of the microscope and learn how to determine total magnification. They walk step-by-step through the procedure of preparing slides...

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...

Nitrogen is an essential element for productive farming. An interactive lesson explores the chemical makeup of different fertilizers and their corresponding nitrogen content. The interactive challenges individuals to complete...

Pupils learn how to control food spoilage by adjusting the food's pH. They see that one of the most dangerous bacteria can grow in food if people don't handle and store food properly. Using knowledge of the bacteria's preferred pH,...

Interpreting graphs is an essential skill for young scientists. An interactive online lesson gives individuals an opportunity to review the components of a graph and learn to read and interpret the shape of a graph. The lesson includes...

Making conclusions from graphs doesn't need to seem like magic. Learners explore an interactive lesson on reading graphs to strengthen their skills. The content discusses how to read the axes of a graph and draw conclusions based on the...

Support your young scientists' knowledge of logarithms with a quick video lesson. The instruction first presents the relationship between a base-10 logarithm and an exponential equation. It then demonstrates how to use a calculator to...

Responsible farming is important for maintaining natural resources. Eager scientists complete a WebQuest to explore what happens to nitrogen when it enters the soil. They learn about the chemical makeup of nitrogen-based molecules...

Students consider the factors that relate to decisions regarding genetic disorders. They read case studies and complete a provided Bio-Ethical Decision-Making Worksheet.

Students are given a fictitious case study to read in preparation for the class. This lesson can also be readily adapted for a role-playing classroom exercise. They discuss the ethical issues of the case.
