What are the different ways to test for pH? First, scholars explore the pH scale and a common way to test for acidity and alkalinity. Then, they learn about the importance of pH in food safety and why variance in pH could potentially...

The road to a better understanding of engineering lies with bridges and tunnels. A set of four engaging activities teaches learners about engineering concepts related to construction projects. They perform an experiment to find the...

Let's go sailing! An instructive unit includes six lessons with multiple activities to teach scholars about density, center of gravity, buoyancy, and the Archimedes Principle. They can complete the final project of building a boat...

There is a solvent called aqua regis that can dissolve gold! After observing a solubility demonstration, groups receive four known crystals and one unknown. Based on the demo, they design an experiment to determine the identity of the...

Here's a solid resource for solubility. Given the solubility of copper chloride at two different temperatures, young chemists need to determine the solubility at a third given temperature. Using a virtual lab, they design and conduct an...

I think I lost an electron. Are you sure? Yes, I'm positive! Starting with a hands-on demonstration and problem solving activity, young scientists define vocabulary related to circuitry and currents. Then they build their own circuits...

That's not what I said! My message did not arrive in the correct order! Introduce the concept of packets and the transmission control protocol used to send and receive information over the Internet. The class participates in an...

Lead your biology class on a cell-sized adventure! Emerging scientists construct models of prokaryotes, then design an experiment to properly grow a bacterial culture. They conclude the activity by viewing the culture under a microscope....

Young chemists perform an experiment to determine if a compound is iron (II) chloride or iron (III) chloride. Then they determine the formula, balance the equation, and answer analysis questions. 

Searching for a relatively interesting way to demonstrate Charles' Law? Here is a lesson in which pupils heat air inside a flask and then cool the flask to quickly cool the air. They make observations about what occurs during the...

Is artesian water designed to be better, or is it just from wells similar to those in the city of Artesium? This experiment looks at many different types of bottled waters, including artesian. Using a soap mixture, scholars test to see...

Students comprehend what makes up the physical community. Read and construct scale drawings and models. Explore the history of infrastructures and how the contributions of science, math and industry have led to the development of their...

Sixth graders discuss what they know and what they want to know about hot air balloon using a KWL chart. They then use a wide array of materials to design a hot air balloon that will lift successfully in cooperative groups referring to...

For this experimental design worksheet, students experiment with three coins, a dropper and water. They determine how many drops of water they can put on each coin. They answer questions about their experiment and they design an...

Students apply the scientific method by building a "Proposal for Study." They label the Observation, Hypothesis, and Prediction columns. Students listen as the teacher introduces the alternative healing methods of therapeutic touch and...

Elementary life science explorers compare and contrast aquatic and terrestrial plants (elodea and soybeans) in a Venn diagram. Some background information is provided to support direct instruction, and general instructions are provided...

Students hatch brine shrimp in a classroom experiment. In this hatching brine shrimp lesson, students participate in two-week lab in which they study how brine shrimp hatch under different conditions. They record data about the control...

Four scenarios of unusual human behaviors are given to your psychology class. Based on their knowledge of brain anatomy and function, they consider what parts of the brain might be affected in order to result in the behaviors. This case...

Young scholars design informational materials to educate people on the importance of matching a new pet to the family's lifestyle and living arrangements. Students use critical thinking skills to make a decision on the appropriate choice...

Students design a paper rocket propelled by Alka-Seltzer and water to demonstrate Newton's third law of motion. They, in pairs, determine the best combination of Alka-Seltzer and water to produce the maximum launch height and record...

Students explore the climate and food sources of Ghana.  In this lesson on climate students view diagrams of global convection and complete a convection experiment.

For this experimental design worksheet, students are given two experimental scenarios to read. They answer questions about each including finding the hypothesis, the independent and dependent variables and controls. They design a graph...

Students explore Earth science by conducting an energy experiment in class. In this windmill lesson, students identify how wind has been used to pump water throughout history and the latest developments wind energy has produced. Students...
