Smog events have become less common in the United States since the Clean Air Acts went into effect. Yet there are still poor air quality events in some areas of the country. Other regions of the world have many more bad air days. What causes poor air quality? Explore the question, will the air be clean enough to breathe? You will be guided through the analysis of models and real-world data as you explore the interactions of factors that affect a region's air quality. You will not be able to answer the module's framing question at the end of the module, but you will be able to predict the effect of human development on a region's air quality.

Fresh water is necessary for life on land, but it is not evenly distributed around the world. Explore the distribution and uses of fresh water on Earth. Explore models of porosity and permeability to determine how water moves underground. Run experiments with computer-based models to determine how human actions affect the supply of fresh water. You will not be able to answer the module's framing question at the end of the module, but you will be able to explain how humans can preserve supplies of fresh water for the future.

In this activity, students create a model ocean over which "wind" will be blown, and observe the relationship between the wind and the resulting ocean surface currents. The activity reinforces the concept that surface currents in the ocean are mostly caused by wind. A materials list and instructions are provided, and links to a glossary are embedded in the text.

Windmills have been used for hundreds of years to collect energy from the wind in order to pump water, grind grain, and more recently generate electricity. There are many possible designs for the blades of a wind generator and engineers are always trying new ones. Design and test your own wind generator, then try to improve it by running a small electric motor connected to a voltage sensor.

Mike Sammartano Youtube Videos
Teachers:
I use several videos published by an 8th grade teacher Mike Sammartano to intoduce or reinforce a Geologic topic. This short lesson on Minrals was one of the first I saw. I use it every term.
This site summary below is posted on Mr. Sammartano YouTube site. I am a subscriber!
Hi there, and thanks for visiting my channel! Most of my videos are flipped classroom videos used in my 8th grade Earth Science classroom. You can find the videos, along with the associated worksheets and diagrams at science.mikesammartano.com. I have also created quite a few educational technology videos including many tutorials on using Apple Keynote in the classroom. Enjoy - and don't forget to subscribe!

Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!
