…force behind electron movement Define electric current as the number of electrons flowing through a wire over a given period of time Explain how conductivity and resistivity relate to electric…
…to graph lines for the first time, or for students who may need extra help or review with this topic. y=mx+b is the second of seven activities for teaching and…
Students explore two new scenarios that involve solving systems of equations. The first situation involves the travel time for a round trip on an airplane, while the second situation involves…
…the diagnostic problem more and more difficult. The fault in the circuit is chosen at random each time you run it, so you can repeat each level for more practice….
…how the protein folds in response to these molecular properties. Explore how the potential energy of the system changes over time to draw conclusions about how proteins develop stable structures….
…use cartoon representations to build “protein complexes” in a model and test the effects of shape and temperature on the strength of the fit. Students review polar and non-polar molecules…
Investigate what makes something soluble by exploring the effects of intermolecular attractions and what properties are necessary in a solution to overcome them. Interactive models simulate the process of dissolution,…
In this unit, students will explore the issue of ocean acidification by investigating the effects of increasing carbon dioxide concentrations in air and water, researching the impacts of acidity on…
…create a protein. Finally, make mutations to DNA and see the effects on the proteins that result. Learn why some mutations change the resulting protein while other mutations are “silent.”…
Investigate how atoms can be excited to give off radiation (photons) with models of electron energy diagrams. Explore the effects of energy levels in atoms through interactive computer models. Learn…
