Students study how fluids of differing densities interact with one another, how densities of fluids can be changed, and how density currents transport and deposit tremendous amounts of sediment in lakes and in the ocean.

Students examine ore deposits and identify factors in their origin. They analyze geologic maps, and locate porphyry copper deposits on a sediment geochemistry map.

Fourth graders research a specific rock or mineral. They compile the facts into a database which students access for information.

Fifth graders, in groups, write about things that happen as a result of interacting with their environment.

Students study the sources for the water they use. They determine their town's major water supply and how many gallons per day does the population use.

Seventh graders use paper bags and crackers to simulate a wildlife sampling of salmon. They record data on spreadsheets and determine a formula to estimate salmon populations.

Learners make molds of various items of their choosing using the Molt-It kit. They discuss the scientific value of making molds.

Sixth graders use a list of robot components and common household items to design and construct a robot spacecraft model suitable for exploring the Saturn System. They present the robots to the class.

Students explore the processes used in the making of polyvinyl chloride (PVC). The types of pollution caused in the manufacturing and use and the problems in the disposal of this product is examined in this lesson.

Students create and analyze graphs using archived atmospheric data to compare the ozone levels of selected regions around the world.

Students construct a 1/80th scale model of the interior of the KAO aircraft, or lay out a full-scale mock-up in their classroom or auditorium. they calculate the sizes of various sections of the cabin.

Students predict which of Jupiter's moons will be the "brightest" in infrared wavelengths. Using provided information, they rank the moos from brightes to faintest in infrared.

Students experiment to discover the relationship between the stretch of a spring and the amount of weight attached to the spring using Skittles. They use a CBR and a graphing calculator to gather data.

Students create an attribute chart to organize their learning about water. They work with a partner to incorporate academic vocabulary to complete their chart. Students may volunteer to share their charts with the entire class.

Students investigate the concept of an aquifer and use a 2 liter bottle and other materials to conduct a simple lab experiment or demonstration. They calculate the volume of water that can be stored in the aquifer. The lab is used to...

Students examine the YSI and the water properties that it measures. They identify the different properties of water pH, DO, temperature, turbidity, and salinity and determine why it is important for them to test these parameters.

Students discuss the term initiating a conversation which means you make statements to begin a discussion with another person. They discuss if you initiate a conversation, then you have to tell the other person that you would like to...

Students conduct an experiment to determine the effects of soil color on its day and night time temperatures. In small groups, they prepare dishes of black soil, brown peat moss, and white sand. They record the temperature changes when a...

Students determine the effect of the earth's tilt on the amount of incoming solar radiation throughout the year. They simulate the earth's orbit around the sun using a light bulb and a globe to simulate the seasons. Assessment questions...

In this planets worksheet, learners access a website and record two unique facts about each planet in 1 graphic organizer. Then students go explore different sections of the website and answer 6 short answer questions.

Students investigate the relationship between voltage and current. For this physics lesson, students observe and collect data from the experiment. They graph the result and share them to class.

Students chart foods on the food guide pyramid and design nutritional food plans that include all the food groups.

Some books are perfect for drawing connections between multiple subjects. The book Hill of Fire becomes the hub for three very different, yet related activity ideas. First the class hones their oral language skills by creating an...

Students use conversion factors to solve problems. In this algebra lesson, students convert between Metric and English Units. They measure different objects and using both systems in their units.
