Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.

Eighth graders investigate the mass, volume, and density of a gas by producing it in a chemical reaction. The entire Density of a Gas Lab and L section of the K W L chart be formatively assessed.

Eighth graders determine the density using mass and volume. In this science lesson, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of known...

Plankton are so abundant in the ocean they outweigh all of the animals in the sea. For this three day activity, groups discuss and become familiar with plankton, capture females, and look for egg production on day three. 

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

Fourth graders discuss density.  In this floating golf ball instructional activity students complete a lab activity on density while working in groups. 

Students explore physical science by participating in a science activity. In this liquids lesson, students discuss how fluids can be affected by motion unlike solids. Students define other scientific vocabulary terms and conduct a motion...

Students design a boat of aluminum foil and calculate the density of the boat. Washers are added to the boat until it sinks. Students then redesign boat to hold more washers and recalculate the new density.

Students engage in a lab project to study chemical reactions. They use guided questions to help facilitate the lab experience and come to the correct outcomes. The activity does not contain a true understandable objective. The activity...

Students use plastic bottles, water, and condiment packets to simulate how natural gas comes from decaying ocean plants and animals. In this natural gas lesson plan, students also fill out lab packets and answer exit questions.

Oceanography experts use candy to construct a model of a bio-physical mooring that would test a variety of factors. Each piece of equipment to be included on the mooring is described within the write-up. As pupils gather the candies for...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. In this geologly instructional activity, learners use scientific...

Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...

Students work with a partner to record observations on various materials. Working together, they calculate the mass and volume of each material and then combine them and shake them for a period of time. In their journals, they record...

Venture into the world of macromolecules with three exciting, distinct laboratory activities. Young chemists examine the forms of carbon and discover how they are associated with atomic arrangement, construct models of carbon-containing...

Learners conduct a series of investigations on the unique properties of water. In this general science lesson, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Students examine icebergs and how they are suspended in water, why ice floats, the melting process of an iceberg, and the floating behavior of ice compared to that of a cork through a lab activity.

Students study the ocean and its characteristics.  In this oceans lesson students complete a lab activity and are able to predict temperature of certain depths. 

Students examine forests as a renewable resource and conservation practices.  In this conifers lesson students complete a lab activity on the different types of wood. 

Students experiment to discover that salt water is denser than fresh water by creating color coded solutions. They examine how heavy rainstorms and high tides develop layers of different degrees of density.

A kaleidoscope is constructed using polarizing polymer paper and then low-density polyethylene, high-density polyethylene, and polypropylene are all melted onto individual glass slides and examined through a microscope. The intent is to...

Another A+ lesson on the impact of climate change comes to you from the National Earth Science Teachers Association. In this installment, learners model the stratification of water in lakes due to temperature differences. The lab also...

Students participate in a mini lab to explore density.  In this density lesson students view a demonstration and answer questions.
