After reading an informational text detailing the ins and outs of snowflakes, scholars draw their own special design then work cooperatively to role play a snowman building scenario. 

This demonstration of solar ponds can be used in an earth, environmental, or physical science setting. Lab groups set up a solar pond and model how it is able, due to a salt concentration gradient, to maintain heat for future use. 

As your young learners develop into cooking enthusiasts, ensure their success in creating their next culinary masterpiece by preparing them to read and understand basic recipe terminology. 

Is there anything better than hot soup on a cold day? Kids prepare either vegetable chowder or minestrone soup in an activity that features the use of the stove top.

Yuck, does my deodorant kill that? To test whether deodorant is anti-bacterial, class members use petri dishes to grow control bacteria and bacteria from sweat, and then compare them to see if deodorant effects the...

Clink, clink! Young mathematicians investigate drinking glasses composed of known solids (cones, cylinders, and hemispheres). Next, they determine the volumes of these glasses.

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...

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

Don't be shocked when your class has a blast making their own batteries! Science scholars examine a dry cell battery, then design and construct a wet cell battery. The activity guides them through the parts of a battery, the variables...

Time to witness the effects of sound. Learners analyze different materials to determine their abilities to absorb sound waves. They use free software to monitor the amplitude of the waves to verify results.

Simulate soil sample assemblages. Individuals create soil layers in a cup. They then use straws to collect core samples from these layers. What information can they glean from the core samples, I wonder?

We all scream for ice cream! Individuals create home-made ice cream in the classroom. This is a delicious way to show a real-world application of the freezing point depression to your class.

A resource rich in information—and nutrients. Learners create agars for the purpose of cell cultivation in Petri dishes. The lesson provides instructions on how to create agars for the cultivation of different microorganisms.

You won't get a stomachache doing an investigative experiment. Pupils simulate the effect of antacids on stomach acid. Obviously, they won't be using real stomach acid; diluted hydrochloric acid serves this purpose.

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

For this mixtures worksheet, students experiment with different amounts of solutes and solvents to make solutions. They observe color changes and look for chemical and physical changes in the test tubes. Students answer 5 questions and...

Students determine the contact angle of water on different surfaces. In this physics lesson, students calculate their percent error using a mathematical formula. They explain the advantages of using non-wetting surface for certain...

In this household chemicals instructional activity, students fill in 10 blanks with answers about testing household materials. Students must also fill out a data table about what color each material turns when placed in cabbage juice....

Third graders explore tessellations and the spatial concepts used in creating them.  In this tessellations lesson, 3rd graders rotate, reflect and transform shapes to create tessellations.  Students become familiar with the...

Students calculate ppm and ppb by using unit analysis when given a ratio of amounts. They determine in ppm what constitutes a health risk for a particular toxin given data and whether local health officials should close a lake...

For this density and buoyancy worksheet, students read about the equation to find density and practice finding the density of substances. They read about buoyancy and match 10 terms with their definitions related to density, buoyancy and...

Students perform experiments in pairs to visualize the changes in water during freezing and melting. In this properties of water lesson, students use their senses and inquiry tools to understand the changes in state of water. Suggested...
