Usda: Virtual Labs: Corn Mold Test Mycotoxins

Learners complete a virtual lab to test for a corn mold that can lead to dangerous toxins. They walk through a detailed step-by-step procedure then see their findings. Throughout the activity, they learn how to use lab tools and practice...

Time to test the limits! Young scientists make limiting reagent calculations and test their math using a virtual lab simulation. Using their knowledge of ionic compounds, they determine the limiting reagents and the excess compounds.

Would you like milk with that? Young scientists consider thermal energy transfer to create the perfect cup of coffee. They calculate the amount of milk needed to reach a specified temperature and then test their calculations using a...

Textbook problems with a twist! Young chemists analyze an ionic reaction to identify the limiting reagent. They then make calculations to determine the concentration of unknown solutions. Finally, they put their work to the test and...

In this science simulation, students investigate water activity in corn that has been dried using traditional Native American methods in order to learn about the best way to ensure food safety.

In this virtual science lab, students learn how to control the pH level in salsa to prevent the growth of a dangerous bacterium.

In this science simulation, students test milk samples to check for bacterial contamination.

In this science simulation, students learn how use gram staining to test for bacterial contamination in yogurt.

In this virtual science lab, students learn how a pH scale works and how to calibrate a pH meter.

There's no risk of injury when working with virtual HCl! Challenge your young chemists with making calculations to create a 3M solution of HCl from the concentrated acid. They first calculate the correct ratios of HCl and water and then...
