Seventh graders are given the opportunity to use model-building as a way to help comprehend the forces and phenomena at work in the world around them. They use both successful and unsuccessful models to make inferences, refine...

Students compare and contrast conditions on Mars to those on our own planet, specifically, their local or regional environments. The physical characteristics, the atmosphere, and other astronomical data is considered.

Students are introduced to some of the fundamental questions about the connections among population, resources and energy use, and environmental impacts. They explore population growth, interpret a line graph and calculate their own rate...

Students assess the ocean's microstructure by analyzing graphs created during tne Ronald H.Brown research cruise. they discuss at what depths various sea animals live and write paragraphs on data analysis from the graphs.

Students examine a density demonstration involving ice cubes and beakers of water and alcohol. After observing how one ice cube floats in water and sinks in alcohol, they determine which mixture of the two would suspend the ice cube in...

Students work together to discover how temperature changes can affect the density of water and air. They make predictions on what they believe is going to occur. They answer questions to complete the lesson.

Students investigate buoyancy, displacement and density.  For this flotation lesson students study the Archimedes' Principle, analyze data and draw conclusions. 

Students describe the way hydrothermal vents work. Students work on locating vent regions through remote collection of data about water temperature and density. Comparing density and temperatures graphs, students search for indicators...

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.

Pupils observe the freezing times and temperatures of water with varying levels of salinity. They determine how icebergs form, how they act, and what they may be made of. They discover that salinity level affects the time it takes water...

Students examine how differences in the temperature and salinity of the water help create ocean currents. They perform an experiment which shows how temperature affects the circulation of ocean water.

Students predict the appearance of a geode's internal structure based on its mass and density. They form a hypothesis based on the data they collect. They also identify common minerals found in Illinois.

Students investigate scientific concepts and inquire about physical states of matter. The transition of water is considered and is easy to facilitate because of its abundance and often observed physical changes.

Students observe a scientific experiment and pose a hypothesis. In this scientific inquiry lesson, students make predictions about the combination of alcohol in water and how it will affect a floating ice cube.

Students describe typical marine food webs, and explain why food is generally scarce in the deep-ocean environment. They discuss reasons that seamounts may support a higher density of biological organisms than would appear to be possible.

Young scholars explore Earth's biosphere. In this biosphere lesson, students participate in group activities regarding biotic and abiotic factors, population density, and species' habitats.

Students discuss radiant energy from the sun, performing a simple experiment with sun glasses and bright light to demonstrate the concept. Students further participate in simple in-class experiments to demonstrate: air density as it...

Students explore what the stoma does for a plant.  In this botany instructional activity students complete a stomatal peel experiment and measure its densities.

Students use this design the illustrate how ink can be separated into its component chemicals using paper chromatography. They use five unknown samples of ink on pre-labeled chromatography strips are provided to students. Students use...

Young scholars are told that any object moving through a fluid (air, water, molasses, etc) experience a drag force which oppose the motion. They are given the summarized version of drag which is proportional to the square of the...

Students compare the weathering of materials. in this weathering lesson, students experiment with the chemical and physical weathering of different materials. Students use salt and water as an example of how weathering occurs.

Third graders act as scientists. In this property discovery lesson, 3rd graders explore the substance "Oobleck" (cornstarch, water, food coloring). They work in groups to investigate the substance and make observations as a scientist...

Demonstrate the movement of lithospheric plates due to convection in Earth's mantle. Learners then model the movements that occur along plate boundaries using colored clay. 

Fourth graders explore and experiment with objects that float to see if they float differently in salt water or fresh water. After the experiment, they write a paragraph in their science journal explaining how fresh water and ocean water...
