Though an alternative method is suggested, the best way to carry out this investigation is with the use of a computer-interfaced motion detector. Physics fanatics hang a mass on the end of a spring and analyze its motion verbally,...

Physics lab groups finagle with laser lights to determine the critical angle of refraction for both water and Lucite. Because there are no detailed steps or an answer key for this enlightening exercise, an inexperienced physics...

Computer-interfaced motion detectors are required to carry out this inquiry. It is a new twist on exploring motion with plunger carts: they are set back-to-back and then propelled away from each other. Their velocities are measured, and...

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

What will your class learn in a curious tale of a fungus, a virus, and a chestnut tree? Biology scholars discover the world of viral biocontrols through a DNA restriction lab. Groups research the decline of the American chestnut tree at...

Transform your class' understanding of genes and antibiotic resistance with the Transformation Lab. Junior geneticists create and observe their own resistant strains of E. coli through research, discussion, and experimentation. The...

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,...

Peer review of science laboratory reports? You bet! First, learners work in pairs to review a scientific article. Then they trade lab reports for peer review. The end result is the publication of a classroom scientific journal!

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...

So is that what you meant by rubber legs? The activity has pairs subject a chicken bone to vinegar and observe what happens over a period of days. Individuals then write up a lab report and document their observations and findings. 

With global temperatures on the rise faster than ever recorded, the effects of a heating planet could be devastating. Allow learners to discover just what the world is in store for if the warming continues through a series of videos, a...

High school physical scientists collide with motion. They work in pairs to design a paper car that will protect a raw egg during a head-on collision. Measurements of distance traveled, time of run, vehicle specs, and photo gate flags are...

What kind of experiment can your class do to how observe the environment effects on organisms? Groups design and conduct lab experiments to learn about the effects of the environment on aquatic organisms. Based upon knowledge gained...

Why does some ink bleed through paper, and other ink doesn't? Practice some paper chromatography to separate the colors from a pen with an interactive experiment for middle and high schoolers. Learners use a variety of solutions to track...

What effects do temperature and carbon dioxide levels have on the zooplankton of Antarctica? This concluding lesson plan in a short unit on climate change and the ocean helps environmental scientists answer these questions. After...

Here's a five-star lesson plan in which inquisitors conduct sophisticated experimentation with cellular respiration in plant seeds. Placing seeds in a closed system they measure the amount carbon dioxide produced and relate it to...

Geometry students will be ecstatic about these engaging and enlightening end-of-the-year projects! Types of project ideas include interviewing a geometer, an ABCs of geometry poster, an engineering lab report, and origami work. 

First in a two-part lesson on the greenhouse effect, this lesson involves a classroom demonstration of the phenomenon, and a lab group experiment with color and absorption. Although there are easier ways to demonstrate the greenhouse...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

This is actually a 10-day mini unit on thermal energy for your high school chemists. Every avenue is taken to get learners absorbed in heat: a pretest, a PowerPoint presentation, Internet exploration, demonstrations, lab activities, and...

To conclude a mini unit on the dissolving of M&Ms® candy coating, this lesson investigates whether or not the concentration of sugar in the solvent affects the dissolving rate. Consider having older science learners write their own...

Which sports drink provides the best pick-me-up after the big game or grueling workout? It may not be the one you'd think! Food science is the focus in a surprising lab activity. Pupils use colorimetry to determine the amount of protein,...

More than anything, this is great practice in scientific inquiry. After discovering that the color coating of an M&M® dissolves in water during a preceding activity, investigators now question whether or not the color makes a...

How do the changing seasons affect the homes where we live? This question is at the forefront of engineering and design projects. Challenge your physical science class to step into the role of an architect to build a model home...
