Do you think the lab smells like rotten eggs? Sorry to hear about your sulfering. A set of five experiments covers many different topics including seasons, gravity, food, precipitation, and photosynthesis. Though not presented as a...

Are you looking for lab sheets to go with your class experiment on plant response to light? You are no longer in the dark! This is a lesson that was written for a unit on light, but could easily be used to demonstrate plant behaviors in...

Can your classes solve the problem of the smelly sweat sock? Young scientists complete a lab investigation that begins by using electrochemistry to generate colloidal silver. They use their solutions to test the rate of microbial growth...

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

Mirror, mirror, on the wall ... who's the best chemistry teacher of them all? You'll get the vote for certain after your class completes the Silver Mirror experiment! Partnered pupils use Tollen's reagent and glucose to silverplate a...

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

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...

Help! Someone's trying to take my DNA! An interesting lab experiment has scholars use basic materials to extract DNA. By applying ethanol, cold water, and a protease enzyme, like pineapple juice, they pull strands of DNA from peas,...

Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...

Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars...

What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine...

Sometimes the simplest experiments leave the biggest impression! Introduce young chemists to the Cartesian Diver by having them make one of their own. Use the Diver to further their study of liquids and gases, as well as compression.

Students study five of the seven life zones in North America. In this journalism lesson students use the Scientific Method working in teams. They use lab equipment and technology to create a presentation on five of the seven life zones...

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...

You can make it if you bake it! Young scientists model electronic chip fabrication with an easy bake oven. They create a design to embed in their brownie "chips" and compare their models to wafer production in basic nanotechnology.

Stephen Perry invented and patented the modern rubber band in 1845. Young scientists put his discovery to work as they use rubber bands to observe entropy and enthalpy. They determine the change in free energy to figure out if it...

No one likes kidney stones, but they are very interesting to learn about. The last installment of a three-part unit has learners experiment with different chemicals to see which one inhibits the growth of calcium oxalate crystals (which...

Given specific materials, scholars follow a set of instructions to build and calibrate their very own spectroscopes. After construction, they test the scope for accuracy and make modifications where necessary.

Get your learners interested in space exploration. Groups design space rovers using design software and then build prototypes of their designs. The farther the rovers can travel, the better. The catch? The rovers must be powered by...

What does an MRI machine have to do with a slinky? This activity challenges learners to run a current through a slinky and use a magnetic field sensor to measure the magnetic field. Groups then change the length of the slinky to see...

This is the perfect resource for helping youngsters understand the importance of physical activity in their daily lives. The lesson and its worksheets focus on brainstorming a variety of fitness activities, such as games you can...

Make the strongest beam possible using taffy? Groups mold a taffy-water mixture into a beam and a reinforcing material of their choice. To finish the final installment of a two-part series, participants test its strength by adding...

Compare the size and shape of crystals grown in different temperature conditions in this science fair project. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by...

Clemson University offers an excellent site of linear thermal expansion lab. Includes experiment, images, charts, links, questions, and much more.
