Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

You're bound to get a reaction from your classes with this experiment! Scholars perform several chemical reactions, make observations, and classify the reactions as single replacement, double replacement, composition, or decomposition...

Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...

Learners conduct a simple conductivity meter to test the ionic or non-ionic nature of water samples including one from their home.

Students explore online tutorial on polymers. In this chemistry lesson plan, they create two polymers in the lab and compare their properties. They write a sales letter about their new and improved polymer product.

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Learners define the key terms that are the structure and function of DNA. In this genetics lesson students complete a lab activity in which they construct a model DNA structure.

Learners develop an understanding of the concept of matter. They l participate actively in the bubble raft experiment as described on the Center for Thermal Spray Research's website. They demonstrate dislocations and grain...

Ninth graders generate and analyze data to determine which and how much of two polymers best absorb oils, formulate procedure to accurately determine how many times its own weight particular polymer can absorb, and develop understanding...

Students practice writing research proposals to test the color fastness of a dye once it has been exposed to a t-shirt. Each proposal needs details of experimental design, length of treatment, and means of cleaning the shirt. All...

Students view a video about the formation of precipitates. They complete a worksheet that asks them to identify what makes a compound form and what holds it together.
