Cell size is limited by the surface area to volume ratio, but why is this true? Scholars measure the surface area and volume of cubes before placing them into liquid. After a set amount of time, they measure the uptake by diffusion for...

Explore the consistency of the earth's layers and soil through modeling. By conducting an engaging experiment, learners develop a model for the earth's layers and a soil profile using edible materials. Each material is chosen based on...

For this identifying the weather terms activity, students read phrases about the weather and choose the term being described. Students choose 11 multiple choice answers.

After reading "Aquatic Alchemy," an article about recapturing water for reuse when in space, your class will use calcium hydroxide or hydrated lime to purify cloudy water. Geared toward high school chemistry or environmental science...

Students study thermal energy and energy transfer to sea ice processes. In this energy transfer activity, students make their own ice cream and discuss energy transfer and thermal energy. Students view a radiation overhead and its role...

In this Earth's environment worksheet, students complete a crossword puzzle given 35 clues about a variety of topics related to our Earth. Topics include ecosystems, precipitation, biomes, energy transfer, soil, weathering and rocks.

Second graders examine the properties of liquids and their classifications. They compare and contrast cups of different liquids and record their findings in journals. Students observe how liquids flow at various speeds and that unlike...

Pupils practice determining liquid densities in a short, hands-on lab activity. Students use a graduated cylinder to measure out 100 milliliters of a liquid, find its mass using a balance, and record measurements in a data table. Pupils...

Seventh graders explore the the constituents and properties of matter. They use the scientific process while exploring solids, liquids, gases, the mass, volume and density of matter. Students plan and conduct an investigation to measure...

In this measurement worksheet, students complete a 12 question multiple choice online interactive assessment about standard modern and ancient measurement.

Students differentiate between high and low viscosity. Students collect, graph, and interpret data, then quantitatively measure polymer solids. Students experiment with a household example of an emulsion polymer.

Students explore physical science by conducting a measurement experiment. In this mass lesson, students identify the differences between mass and weight and define a list of other vocabulary terms. Students utilize electronic scales and...

Students observe and demonstrate how objects can be charged positively and negatively and how static electricity works. They observe a teacher-led demonstration, and in small groups rotate through various static electricity activities,...

Students work in a mini lab where they measure the temperature every 30 seconds for several minutes as water is heated. They are asked what makes liquid different from a solid. Students view a PowerPoint on the model of liquids,...

Students investigate coefficient of friction with respect to surface area and applied force in contact with the sliding force.

Fourth graders observe air pollution that is visible and invisible with experimentation. During the experiment the students collect data that needs analysis. The observations are recorded in the lab journal. The data also is represented...

Students differentiate the three states of matter. For this chemistry lesson, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.

Students explore physics by conducting a class experiment. In this density lesson plan, 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...

Here's a great selection of slides for a class being introduced to heat transfer. Types of materials that are good conductors or insulators are covered and the diagrams that accompany the information should make understanding more...

I scream, you scream, we all scream for ice cream! Even high schoolers enjoy making ice cream. This laboratory exercise has them record the temperature changes throughout the process of liquid becoming solid, graph the results, and...

Class members read 25 clues about all areas of science, including biology, chemistry, weather, physical science, and insert their answers into a crossword puzzle. There is no word bank and the middle schoolers would need experience with...
