Students investigate the density of liquids. In this geometry lesson, students calculate the volume and differentiate between volume, mass and density. They observe similarity and differences between coke and diet coke.

Students complete a unit on the effects of pollution on our water supply. They create a graph to examine the density of earth's land surface, round the population to the nearest hundred million place, participate in a...

In this population worksheet, students click on the links and research the internet about population, land, and government. Students answer 16 short answer questions including making spreadsheets.

Students conduct a lab (with water, guar gum and sodium borate) and carefully record physical and chemical properties and changes throughout the session, and experiment with weighing by difference.

Students build a hydrometer to measure the densities of fresh and salt water samples. They record the water temperature and density and use the temperature, density, and salinity conversion graph to locate the salinity. Finally,...

Fourth graders examine patterns that influence population density in the various regions of California. The unit's three lessons utilize graphic organizers for the interpretation and presentation of data.

Second graders explore floating and sinking and make predictions about whether certain objects are likely to sink or float. They read the story Who Sank the Boat? by Pamela Allen. Pupils loacate rhyming words and discuss the events of...

What did the sea say to the boat? Nothing, it just waved. An inquiry-based instructional activity starts with a simple concept on the Archimedes Principle and challenges pupils to make something out of clay that floats....

What do we do when a dive is too dangerous for humans to accomplish? Send in the robots! Middle school scientists get acquainted with several different models of submersible robots in the second instructional activity of six from NOAA....

Using a stream table, erosion enthusiasts examine how the density of sediment and how the slope of land contribute to the amount moved by waves. You will not be able to use this entire resource as is; there are teachers' names and...

Learners conduct a science experiment to determine whether a variety of objects will sink or float. They discuss the concept of density, and then make predictions about whether the objects will sink or float. They then conduct the...

Almost 200 slides make this a vast collection! It is a quirky collection, titled "Marine Fisheries Management," but having little to do with that occupation. What you will find are two-toned blue backgrounds with no pictures, but a few...

In this gas laws worksheets, high schoolers figure volumes, densities, molar masses, reactions, and solve equations as they encounter 14 gas laws questions.

Learners view macroinvertebrates, or discuss previous collection activity. They graph data on macroinvertebrates in the Hudson River. Students discuss the relationship between habitat, environmental changes, and invertebrate diversity or...

Sixth graders develop an understanding of floating, sinking, density, and buoyancy and apply it to the design of testing of ships.

Using a magnifier, mini marine biologists examine the barbules of a bird feather. They swirl the it into a mixture of oil and water and then re-examine the feather. After the activity, discuss how the oily feathers pose a problem to...

Young scholars observe, over time, microbes such as amoebas, protozoa, rotifers and insect larva. They create a hay infusion culture using pond water then sample and record organisms found over a two week period.

Students explore the effects of aquatic trophic relationships on water transparency. They observe and explain the effects of reducing nutrient inputs on agal density on water transparency.

Students analyze a research report and the list of components needed in a research report and then identify those components based on a set of standards using the scientific method. They collect data which can be used for a graphical...

Students investigate how temperature and salinity causes ocean layering. In this ecology activity, students observe and sketch their experimental result. They report their findings in class.

In this measurement instructional activity, students determine how gravity affects your weight and mass on a different planet. Students practice converting measurements to different units. This instructional activity has 12 problems to...

In this chemical solutions learning exercise, students determine the molecular weight of a substance, determine the boiling and freezing point of solutions, and determine molarity of a solution. This learning exercise has 3 problems to...

Students use scientific methods to investigate the effects of overpopulation of seed plants on growth in a limited living space. Students relate seed plant population findings to that of other organisms.

In this Earth's atmosphere worksheet, students observe the effects of air pressure using an egg. They describe what happens to the egg and what makes it do what it does. Then they determine how to get the egg out of the bottle opening at...
