Pupils experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.

High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...

Students explore the states of matter. In this physical science lesson, students observe what happens to water when it freezes and record observations. Students then observe ice when it melts and record observations.

Students examine how salt water is more dense than fresh water through experimentation with eggs.

What is the best way to test water quality? Using plastic bottles, scholars create monitoring sensors to test water quality. Creating three different sensors allows individuals to measure water quality at different water levels.

First graders examine the water cycle through readings and experiments. In groups, they conduct interviews with others and use the information to create a chart displaying the various uses of water. After brainstorming lists of ways to...

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.

In this layer of the earth worksheet, students label and color each layer of the earth. Then students are asked to describe each layer below.

In this seasons worksheet, students cut out the picture cards at the bottom of the page, sort the pictures and paste them with the matching season.

In this worksheet on the life cycle of the butterfly, students look at 4 pictures representing the life cycle stages, and choose words from a word box that match each picture. Students then number the pictures in the correct order of...

For this density worksheet, students explore an internet program called Gizmo where they do an experiment with density. Students complete 18 questions.

Although this is a science lesson, it can be adapted to help meet Common Core standards in math as well. Starting scientists describe physical properties of objects and explore three forms of water. To address the Common Core, they can...

In this salinity worksheet, students simulate conditions of salt and fresh water mixing and observe the various densities of these solutions based on their salinity.

Learners research the development and implementation of a research vessel/vehicle used for deep ocean exploration. For this oceanography lesson, students calculate the density of objects by determining the mass and volume.

Students investigate different liquids to develop their concept of a liquid. They work at a center to tip, swirl, shake, roll, and otherwise investigate seven liquids in small, clear plastic bottles: plain water, corn syrup, liquid...

Students investigate surface tension and bubbles. In this scientific inquiry lesson plan, students explore how the surface tension of water is able to support tiny objects that actually weigh more than the water as they collect date by...

In this elements, compounds, and mixtures worksheet, students answer questions about the properties of elements, mixtures, and compounds. Students identify the physical changes that is made to a substance to determine if it is an element.

Students research inventors and inventions and their impacts. In this invention instructional activity, students research inventions and their affects in good and bad ways.

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.

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 examine and identify the observable properties of coal. After a lecture/demo, students perform a simple experiment. They observe samples of coal and record data in an organized manner.

Students work together to create a watershed model. They discover the flow of surface water on different topography. They examine how materials originate from miles away and end up in a different wetland.

Students study the structure of the lungs. In this lung structure lesson plan, students use lung models to study the structure of lungs and experiment to measure the amount of air in the lungs.

Students will investigate what determines whether a material will sink or float. They will be given a bowling ball and have to make measurements and conclusions on whether their bowling ball will float, hover, or sink when placed in an...
