Curated OER
Sink or Float?
Students analyze the relationship between density, buoyancy, and salinity. In this chemical properties lesson, students read a background activity for the lesson and experiments to the topics. Students discuss the questions and complete...
Curated OER
Global Environmental Change
Students examine environmental change of land, water, and air, discuss Clear Skies Legislation, and experiment on solid compaction and
resultant water filtration.
Curated OER
Earthquake!
Students study causes, probability and location of earthquakes. They complete a number of activities and look at web pages to examine the characteristics of earthquakes.
Curated OER
Inside Earth
Young scholars study the makeup of the earth, including the core, the mantle and the crust. They compare the temperatures and thicknesses of each layer. In pairs, they make a model of a cross-section of the earth out of modeling clay.
Curated OER
Microscope Investigation
Young scholars explore physical science by participating in a science examination. In this microscope tutorial instructional activity, students read the book The Naked Eye and discuss the purpose for using a microscope in the field of...
Curated OER
Water Pollution
Young scholars study four samples of "rain water". They asked to determine the pH of the samples and then to neutralize them. Students are asked to predict any negative effects which might be associated with water having a low pH and...
Curated OER
Comparing Local, National, International Biomes
Pupils calculate averages of climate sets of data. In this ecology lesson, students analyze data to determine identity of a biome and collect meteorological data to understand process. Pupils also compare data sets.
Curated OER
Transpiration
Learners interactively explore the term transpiration. In this science/ecology lesson plan, students discuss what they would do if they were thirsty while conducting research in Brazil. Additionally, learners write descriptive words to...
Curated OER
Understanding Salinity
Students discuss why the ocean is salty. They discuss what salinity is. Students are told that is they want to know how much salt is in a body or water, they would use a special scientific tool. They complete an Estuarine Layers science...
Curated OER
Froth Flotation
Sixth graders experiment with the froth flotation process to extract metallic ore by using basic chemicals and equipment in the science classroom.
Curated OER
Let's Go! Virtual Yellowstone Tour
Students research the geologic wonders of Yellowstone National Park. They locate the main geologic features of Yellowstone on a map of the park. Students write a description of the geologic features to be included on the map for a...
Curated OER
Mining Bingo
Students review the list of definitions of mining terms before playing bingo. They fill in each square using one word or term per square leaving no square blank before playing the game.
Curated OER
Dinosaur I Finding And Dating
Students investigate how long dinosaurs lived on Earth and how that compare to how long man has been on Earth. They discover how scientists excavate fossils.
Curated OER
Solubility and Chemical Changes in Groundwater
Middle schoolers test pH of water before and after it travels through different substrates (igneous pebbles and limestone) to detemine how soluble materials can affect groundwater. They answer questions such as: What happended to the pH...
Curated OER
Detecting Magnetic Materials in "Martian" Soil
Young scholars simulate some of the Pathfinder experiments by devising methods of collecting and measuring magnetic substances in pseudo-Martian soil. The efficiency of each of the methods used to collect materials is evaluated in this...
Curated OER
What is a Ruminant?
Students examine the way bison eat and digest their food. Using a diagram, they follow the food from one compartment to the next. They discover that bison are ruminants and discuss why the bison need four stomachs.
Curated OER
What's Under There?
Students determine ways to make "observations" about unknowns, such as the land beneath an ice sheet or the interior of the Earth, using tools other than sight. They build "mystery boxes" and exchange them with other groups to "map"...
Curated OER
Soil Analysis
Students examine zip lock bags of clay, silt, and sand to determine its origin. They rotate through stations to compare different soils and perform oil separation and Tullgren funnel tests.
Curated OER
Jupiter's "Monstrous" Magnetosphere
Students explore Jupiter's magnetosphere. In this Jupiter instructional activity, students examine a diagram of the magnetic field that surrounds Jupiter.
Curated OER
Water Quality
Students play the role of scientists testing for water quality in the area. In this ecology lesson, students determine the water sample's pH, temperature, dissolved oxygen and turbidity. They write a journal reflection after the activity.
