Students use density to identify what metal a gold colored weight is made of. They use a spreadsheet to graph the experimental density of common metals and compare the know densities to their calculated density of the known metal.

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 lesson of six from NOAA. Lab groups then...

Students explore physical science by conducting an in-class experiment. In this density lesson, students define vocabulary terms dealing with physics and discuss their knowledge of density. Students conduct several "sink or float"...

An engaging unit on wildfires includes three sections, including a background section with eight lessons and five activities, a field experience section with 13 lessons and five activities, and a conclusion section featuring an...

Learners follow directions for a simple chemical experiment. They use the appropriate tools and techniques to gather, analyze, and interpret data. Students identify a substance that has characteristic properties, such as density, a...

Students explore physics by conducting a class experiment. In this density activity, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five...

Pupils investigate buoyancy by participating in a lab experiment. In this density lesson, students utilize vinegar and alcohol in beakers and attempt to float different items in them. Pupils analyze which items float and do not while...

Students explore the effects of different density-dependent and density-independent factors on population growth. They explore how the interactions of organisms can affect population growth. Students explore the pattern of population...

Students identify and complete activities about the structure of the Earth. For this Earth structure lesson, students view a Powerpoint about the Earth's layers and complete a diagram. students compare temperatures in the Earth's layers...

Students create observable layers in water that represent a separation based upon density differences. They model density boundaries using differences in temperature and salinity. They, in groups, perform a meaningful experiment...

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

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...

Young scholars inspect nutrition by conducting a science experiment in class. In this vegetable identification lesson plan, students examine a group of different veggies and predict whether they will sink or float in a tub of water....

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...

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

Students elicit data on the water cycle, ocean topography, and island formation in this six lesson unit. The ocean floor and the properties of water are examined through a variety of discussions and hands-on experiments.

Students, in groups, design a procedure to calculate the mass of gas molecules in the classroom by measuring the volume of the classroom and researching the density of air. They apply changes in air density with altitude and effects on a...

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...

Students analyze the impact of human activity (e.g., population density, pollution) to a country where the target language is spoken. They prepare a three paragraph essay and describe the impact of pollution on the environment and the...

Unfortunately, the article for which this resource was written is not available. You can, however, find another current document on agriculture and urban development for your class to read together, and then still follow the suggested...

Students explore biological impact by completing a worksheet in class. In this animal population activity, students utilize river rocks and jars to conduct a coqui frog population role play activity. Students define a list of amphibian...

Students explore physical science by participating in a class experiment. In this chemistry lesson, students discuss what they predict will happen when cooking oil and water are blended together. Students utilize a plastic bottle,...

Learners 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.

Students make generalizations about weight and mass by engaging in two hands-on experiments. In this weight and mass instructional activity, students weigh both an empty beaker and beakers with various amounts of weight inside of them in...
