Grandma said to gargle with salt water for a sore throat. Was she right? In the last part of the seven-part unit, lab groups design an experiment to test a cells reaction to salt solutions. The pupils conduct their experiment to answer...

Learn about damage associated with earthquakes and materials that best withstand a quake. A lab engages class members in the experimental design and construction of sturdy structures that can endure various earthquake...

Get things moving with this extensive collection of physical science resources. Covering the fundamentals of measurement, graphing, lab safety, and experimental design as well as the specific scientific concepts...

The scientific method keeps you from believing only what you want to believe — it expands your mind. The lesson plan introduces the eight steps in the scientific process and how to design an experiment to biology scholars. Live insects...

Ever wondered what motivates a roundworm? Introduce your biology class to C. elegans, a non-parasitic model organism that can help them understand behavioral stimuli. Paired pupils design an experiment to test the worm's reaction to...

Investigate experimental design through a hands-on exploration. A creative lesson allows learners to design an experiment to monitor the effects of alcohol on the C. elegans worm. After conducting the experiment, individuals analyze...

Protect skin from UV radiation! Groups design and conduct an experiment to test the effectiveness of UV safety products. The groups collect the data from the experiment and prepare a lab report. In the second day of the activity,...

Caffeine affects your heart rate — or does it? Learners study experimental design while conducting their own experiment. They collect heart rate data after drinking a caffeinated beverage, create a box plot, and draw conclusions....

Waste not, want not! Science scholars explore manure as an alternative energy source through reading and experimentation. Groups construct their own biofuel digesters and observe the process of methane production. The teacher's guide...

So much science in one tiny fish! Introduce young biologists to the zebrafish, a common aquarium inhabitant. The small, unassuming organism presents an opportunity for learners to study habituation using an easy-to-care-for species. Lab...

Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a lesson that stresses the importance of controlling all variables. The second activity...

Car crashes provide an excellent way to study kinetic energy transfer. Scholars explore energy through hands-on simulated crashes. They work together to design their own experiments and apply the knowledge gained to a situation that...

Become a bean counter. Pupils use a fun activity to design and execute an experiment to determine whether they can grab more beans with their dominant hand or non-dominant hand. They use the class data to create scatter plots and then...

Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

Test the efficiency of your memory! Scholars test each other's memory as they explore factors that affect memory retrieval. Through experimental analysis, they discover there are different types of memory, which has an impact on the...

Can you feel that? Can you smell that? Since pupils can't ask worms about their sense of smell and touch, they design and complete an experiment to answer these questions. Individuals expose nematodes to different stimuli using their...

Challenge your classes to complete an experiment from beginning to end. Learners make their own hypotheses, collect and analyze their own data, and make their own conclusions. They are on their way to becoming statisticians! 

You have to crack a few eggs to make a good engineer! Working in small groups, young scholars design, build, and test devices that protect an egg from breaking when dropped from a ladder.

Have you ever wondered why some people are lactose intolerant? Participants test simulated patients in a hands-on lab activity to find out! They learn about lactose intolerance by performing an experiment, analyzing data, and drawing...

Things are really getting heated in the lab! Science scholars scope out the facts about heat energy transfer using a simple lab from the K20 Center. Groups collaborate to observe temperature changes between hot metal and water, then use...

This is not your standard standardization lab! Take titration into the high-tech age with a simulated workbench. Learners perform titrations to standardize a sodium hydroxide solution using a KHP solution of unknown concentration....

When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...

Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome.
