Students explore erosion when there are multiple types of sediments. They view a soil separation demonstration jar before and after agitation to determine how and why the layers settled. In addition, they conduct experiments with a river...

Zap! Ouch! That hurts! But why? And how come people don't experience or respond to pain in the same way? Take a journey on the sensing pathway, from your nociceptors, along your nerves, up your spinal cord, to neurons and glial, through...

Here is an interesting science activity/activity which has learners working in groups in order to simulate experiments done at the Jefferson Science Lab. In this one, groups use a pie tin, a Hula Hoops, a marble, and a magic marker to...

Students use forensic science to positively identify any suspected drugs submitted to the laboratory. They determine the identity of the drugs found in the bodies of drug-overdose victims. Students use TLC to identify the active...

Get scholars thinking about the scientific process with this fun experiment they can do at home. Learners practice reading directions as they underline each instruction in a procedural paragraph. They create a flow chart and record...

How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

Students compare the perceived and actual risks of getting skin cancer, while looking at ways to minimize these risks. They may have very little grasp of the severity of the threat of skin cancer or be unaware of the increase in the...

This is a terrific resource for practicing the scientific method or for examining the claims of different sunscreens when learning about electromagnetic radiation. You may have to improvise, however, as it was written to accompany a...

Ninety-seven percent of scientists who study climate agree that human activity is warming the planet. Learners explore carbon dioxide as a greenhouse gas, a gas causing this warming, through a hands-on experiment. Once complete, they...

How much does your class know about the relationship between climate change and carbon dioxide? Science scholars explore the nature of greenhouse gases and rising ocean temperature through demonstrations, research, and experiments. The...

Here is a nice, clean wrap-up activity for your chemistry class when they are studying chemical reactions . They experiment with different oils to make soap. To make it more fun, they are to imagine that they are part of a soap testing...

Students recognize epoxy glue formation as two part polymerization (usually the curing agents act as co-monomers). They monitor the reaction by the changes in viscosity of the reacting mass, the temperature rise and fall, and the...

Students are challenged to come up with a good estimate of the amount of air in foamed polystyrene products. They use this gas evolution experiment and as such have students measure the gas generated when foamed polystyrene is degassed...

Students experience a "hands-on" activity to get visual evidence of the physical nature of DNA and the process of DNA purification. They explore one method of chromosomal DNA isolation and DNA extraction.

Sixth graders design experiments to compare the amount of bacteria in river water to the amount in purified tap water. They explore how water purification removes bacteria and pollution from the water. Students examine the steps of the...

In this chemistry worksheet, students examine a concept in science and then use the knowledge in application by conducting an experiment.

Some background information about density and Newton's Laws of gravitation and motion assist pupils in the following experiment. The procedure will help them further their understanding of gravity, pendulums, and a drop-ball experiment....

Young scholars examine elastomeric polymers in a lab activity in which they design a bungee cord. Students must determine the tensile strength, percent elongation, and plot stress versus strain graphs for their experiments on rubber...

Students are introduced to bacteria and their role in biology and finishes with a lab experiment that focuses on antibiotics. They are given an overview of the important concepts involving bacteria and their potential resistance to...

Nothing says classroom fun like an invertebrate and a magnifying glass! Snails, earthworms, and roly-poly bugs become the center of attention as pint-sized investigators hone their inquiry and observation skills. They are...

Students are introduced to the analysis of health risks in the laboratory, particularly from vapors from organic solvents. They consider quantitative measure of risk such as threshold limit values (TLVs), the amount of the compound that...

Students identify the four basic natural resources. They distinguish bettween renewable and non-renewable resources. Pupils recognize that all natural resources are needed by living plants and animals. Students list consequences for...

Seventh graders view "Volcano" by National Geographic Video. They experiment with baking soda and study lava flow. They describe volcano and earthquake patterns. They analyze weather and climate changes and how they relate to the natural...

Where does all of the carbon dioxide come from that is supposedly leading to climate change? Earth science pupils test animal, plant, and fossil fuels as sources in this investigation. Using an indicator, BTB, they are able to detect the...
