Weathering and Soil Formation
A set of 27 slides systematically shows how weathering, erosion, and deposition contribute to soil formation. Both chemical and mechanical weathering are described, as are resulting soil layers and properties. There is no longer any need...

Towers of the Lost City
Middle school marine scientists compare the pH change in distilled and saltwater as acetic acid is added one drop at a time. Then they compare the pH change in both when sodium hydroxide is added. This experiment demonstrates the...
American Chemical Society
Crushing Test
Solidify understanding of the properties of crystals by crushing them to compare hardness. After some class discussion, a procedure is planned, and then small groups go about making observations as they crush five different crystal...
NOAA
Please Pass the Salt
Salinity is the focus of two experimenters that work to answer the question, How does salt change the physical properties of water? Super scientists compare the freezing rate of salt and fresh water, combine the two waters to...

Avoiding Carbon Dioxide Emissions from Burning Fossil Fuels
Chemistry and earth science meet in a lesson on carbon dioxide emissions. After reading about atmospheric problems caused by using fossil fuels, science stars balance equations for the burning of different alkanes. They compute the...

Landfills and Recycling
Examine the nature of landfills through experimentation. Scholars build miniature landfills and monitor changes over a six-week period. Observations allow individuals to draw conclusions about the different types of trash and their...
Curated OER
Ammonium Nitrate - Heat of Solution
Young scholars quantify the relationship between temperature, energy and heat
and define an endothermic reaction. They measure the energy change caused by dissolving one mole of ammonium nitrate in water.
Curated OER
Changing How Things Look
Third graders use a literature study in order to investigate how organisms effect an ecosystem. They are asked questions about change taken from the book. Students also take a nature walk to make field observations.

Weathering Experiments: sugar cubes, steel wool and gravel!!
Students study the chemical and physical weathering of "rocks". In this weathering experiments lesson students complete a lab that demonstrates how rocks weather.

Outcomes Science 4: Earth & Beyond
In this earth and beyond science worksheet, students read through 11 pages of information on weather, global warming, climate change and other related topics. There are many website links on the pages that provide additional information...
Curated OER
One for the Money
Eighth graders sort items as they are shown one at a time by the teacher. They attempt to identify the one physical trait the teacher is looking for (metal and not metal). After several objects have been shown and placed in groups, the...
Curated OER
It's in the Bag!
Eighth graders measure temperature changes and make drawings of the interactions between matter and energy. By measuring the temperature students can conclude if there are changes in levels of energy.

Chemical Bonding
Eighth graders identify the three main types of chemical bonds. In this chemistry instructional activity, 8th graders draw Lewis dot diagrams of elements and determine the bond formed. They create a model water molecule.
Curated OER
The Physical Setting
Tenth graders examine chemical reactions. In this chemistry lesson students choose an investigation that they wish to perform based on their interest.
Curated OER
Enzymes
Tenth graders test their saliva for enzyme activity. In this enzyme lesson, 10th graders conduct an experiment to test the enzymatic activity of their saliva. They relate the lack of certain digestive enzymes with alcoholism.
