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....

For this chemistry worksheet, students read about the differences between substances that are acids and bases. They read about Litmus dye and the pH scale. They experiment with six household substance by testing them with litmus paper to...

Students examine the changes in Earth's temperature. In this global warming lesson, students perform an experiment testing temperatures of soil. Students record their findings and discuss what made the differences in the soil temperature.

Through two investigations, life science learners determine whether or not yeast is alive. They perform tests for metabolism by providing sugar and observing if gas is produced as a byproduct. They incubate some of the sample for at...

Within the setting of a crime scene investigation, biochemistry beginners analyze organic compounds as a means of determining "Who dunnit." They use a brown paper test for lipids, glucose test strips and iodine to identify carbohydrates,...

Earth science learners experiment with the water-holding properties of sand, pebbles, and clay. They apply their findings to the building of a well. This activity is engaging and tactile, and it demonstrates the importance of considering...

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. 

Equip young campers with important survival knowledge with a set of engaging lessons. Teammates work together to complete three outdoor activities, which include building a shelter, starting a campfire, and finding directions in the...

Stop the raindrops from getting into the house! Eager engineers learn about roofing history and waterproofing by nanotechnology. They get into groups and work on designing a waterproof roof for a small model house. The accompanying...

Forensic scientists depend on their observation skills to analyze evidence down to the molecular level. Middle and high schoolers practice making observations and predictions with a series of crime scene activities, which includes a...

Knowing about the hydrologic cycle is the first step to understanding the carbon cycle. Upper graders discuss the earth's water content, polar ice caps, and the concept of the ecological cycle as it applies to carbon, nitrogen, and other...

Glaciologists in your class make models of glaciers to simulate how they move down a valley, and then they use it to test any aspect of glacier movement. Not only is this a vivid visual of how these monsters of ice flow, but it is also...

Test six various reagents for their ability to conduct electricity. Cooperating chemists research whether each is ionic or covalent and discover the relationship between bonding and conductivity. This laboratory exercise would be an...

Looking for a terrific chemistry lesson for your 5th graders? This one could be for you! After a teacher-led demonstration, learners are broken up into groups and perform an experiment using cabbage juice, water, window cleaner, and...

Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

This well-organized lab activity introduces earth science pupils to the greenhouse effect. They will set up two experiments to monitor temperatures in an open jar, a closed jar, and a closed jar containing water. Ideally, you would have...

Children enjoy playing with silly putty, but it provides more than just fun. Young scientists make their own silly putty using different recipes. After a bit of fun, they test and graph the viscosity of each.

Was Metro City negligent? The parents of a young AIDS patient sue the city when their son dies after drinking water from contaminated pipes.

Budding biologists often ask how scientists know what they do about different topics. In the lab described here, they have a chance to find out first-hand about the requirements for photosynthesis. Three sequential investigations are...

Students design, build, and test the specifications (water displacement and load line) for a model boat. The lesson focuses especially on integrating design principles with inquiry-based experimental skills.

Scholars collect data from heating sand and water before forming testable hypotheses about why sand heats up faster. Afterward, they develop and run experiments to test their hypotheses.

Five individuals in the class are "infected" with cholera! The rest of the class serves as investigators to discover the source of the outbreak. They test drinking fountains around campus for contamination. You, of course, will secretly...

Some weddings have flowers in a unique, unnatural color to match the theme. Young scientists take part in this process to learn about the function of the xylem as they observe colored water moving through a flower. Then, they experiment...

After reading about the history and science of personal floatation devices, patents, and intellectual property, engineering teams design a life vest for a can of soup. To evaluate which groups considered the need for waterproofing, hold...
