The Impact of Acid Rain and the Greenhouse Effect on the Environment
Students study acid rain and complete several activities that show how it affects the environment. They role play members of the community involved in a major decision involving the protection of the environment.
Curated OER
Distant Relatives
Students investigate observations between widely separated populations of anchialine cave fauna. In this biogeography lesson students discuss theories that could explain the given observations.
Curated OER
Ocean Currents
Students label the names, relative temperature, distribution, and direction of flow of major ocean currents on a world map. They also explore and model the natural forces that affect the movement of ocean currents through demonstrations...

Planets
In this planets worksheet, students read information about Mars, Jupiter, and Saturn and then complete 21 multiple choice, 1 true or false, and 2 fill in the blank questions.
Curated OER
Ocean Currents Quiz
In this ocean worksheet, students complete a 13 question multiple choice on-line interactive quiz about ocean currents. Prior knowledge is assumed.
Curated OER
Clouds and Rain
Students study how clouds form, what different types there are and what rain is. In this atmospheric lesson students make a cloud and create evaporation.
Curated OER
Deposition
Students follow carefully designed instructions to bond silver to glass thus creating a mirror. The process used, Brashear's Process, uses sugar rather than formaldehyde to reduce the compounds, but many of the chemicals are dangerous,...
Curated OER
Look At What Nature Has Done!
Students examine how easy it is to break rock. They investigate weathering and erosion in a number of activities.

"Fish: Anatomy and Diversity in the Chesapeake Bay"
Young scholars explore a variety of basic fish body form and their functions. They differentiate between different species of fish found in the Chesapeake Bay and St. Mary's River. In addition, they match pictures with descriptions using...
Curated OER
Resistance is Futile
Students participate in two hands-on demonstrations to explore how friction can make objects hard to push.
Curated OER
Miller-Urey Experiment Amino Acids & The Origins of Life on Earth
Students study the Miller-Urey Experiment including its history and criticism. In this origins of life lesson students repeat this experiment to see how it works.
Curated OER
Regolith Formation
Students compare and contrast the process of regolith formations. In groups, students define regolith and discover how regolith is formed on the Earth and on the Moon. They participate in experimental activities to simulate regolith.
Curated OER
Feeling Pressured
Students explore pressure in our atmosphere. They examine the relationship between pressure and depth. Students construct an experimental apparatus and take measurements. Students evaluate the impact of pressure on the lungs.
Curated OER
Spider
Students use a spider casting kit to mold a tarantula spider. They discuss the tarantula, its parts, and its habitat.
Curated OER
Air Masses
Students are given maps depicting two or more air masses and they then categorize bodies of air by temperature and moisture characteristics. They recognize large regions of similar type air. Students are given a map of air temperatures...
Curated OER
HOW FAST DO SEDIMENT GRAINS OF DIFFERENT SIZES SETTLE?
Students conduct an experiment using sand, a jar, and a paper clip to analyze the effects of different kinds of sand vis a vis its sediment. They graph their findings and analyze for factors of size, shape, and density.
Curated OER
Fossilworks
Young scholars research fossils and fossil formation. They explain how fossils are formed, identify fossil formations and use casting plaster to produce fossil replicas.
Curated OER
Reclamation
Young scholars recognize the importance of reclaiming the land after mining. They observe the experiment demonstrating the process of erosion and record their results of the effects of rain upon the land.
