How do you know there is air? Can you see it, smell it, feel it? To begin the investigation, learners watch a video and discuss what they know about air and the atmosphere. Then, they participate in five different hands-on, inquiry-based...

Scientists need to figure out how to measure interplanetary magnetic fields, but the magnetic field of the spacecraft is interfering with their readings. Scholars attempt to solve the problem that has perplexed NASA scientists for years.

Astronauts train underwater to simulate the change in gravity. An out-of-this-world unit includes three hands-on activities, one teacher demonstration, and a discussion related to some of the challenges astronauts face. Scholars apply...

Get your classroom rocking with this four-lesson earth science unit. Through a series of shared reading activities and hands-on investigations, young geologists learn about the three types of rocks and the unique properties of each.

Hot off the presses, this collection of thermal energy activities, lessons, and printables is sure to amaze. Demonstrate how thermal energy moves about in a system using simple materials. Pupils demonstrate their understanding...

There's quite a bit in this physical science packet. First, how is heat transferred? Learners read a brief explanation of conduction, convection, and radiation before identifying common occurrences (with pictures) as one of the three....

A comprehensive resource gets fourth grade physical scientists making observations about the period of a pendulum and then applying knowledge to a playground swing. Through seven different stations, they will record observations and...

Whether you want to heat things up in science class or cool things down a bit, an intriguing lab's got you covered! Science scholars explore the principles of thermodynamics using a solar oven, then change the conditions to turn their...

By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...

Stress the importance of the different types of pressure our mind and body experience in a lesson about how certain types of stress are actually necessary and good for our bodies. As astronauts and people with injuries can attest, not...

Carbon dioxide is a very important gas; it is present in the air, used in cooking, and supports plant and animal life. Scholars investigate the properties of carbon dioxide with three different activities. They experience a color change,...

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

Roll up your sleeves and get a little dirty with this elementary and middle school compost lesson plan. All you need is a large plastic container, a couple old newspapers, some organic waste, and a few hundred worms and you're ready...

Want to hear a joke about sodium? Na. Young scientists test various materials to identify if they include protein, starch, and glucose by using the Biuret test, iodine starch test, and Benedict's test respectively. After practicing with...

What better way to learn about muscle than by dissecting one? Using cow muscle (beef), learners compare bundles of yarn to muscle fibers as they explore each. The supplemental reading about astronauts losing muscle mass in space and what...

Pupils often wonder how we know the distance to various stars. Starting with a thought experiment and progressing to a physical experiment, they determine the brightness and distance to various stars. The evaluation requires...

How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Amazing science can sometimes happen right before your eyes! The class gets cozy as they watch crystals grow. They use Epsom salts, rocks, and food coloring to create crystals. They'll observe the entire process, documenting every step...

Tune in! Young scientists use an AM radio at home to monitor solar output. The long-term project would be ideal in a flipped classroom or as an out-of-class project. 

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....

Teach your exercise enthusiasts to read their pulse rate at the radial artery and multiply by four to calculate beats per minute. Learners perform a variety of activities, recording their heart rates after one minute of each. Though...

The sun sends the earth 35,000 times the amount of energy required by all of us on the entire planet, every day. The fourth lesson in the 10-part series looks at how light energy from the sun transfers into thermal energy. Scholars build...

Make your lesson on radioactive decay pop with this lab exercise. Using popcorn kernels spread over a tabletop, participants pick up all of those that point toward the back of the room, that is, those that represent decayed atoms. As the...
