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...

Use the classic density demonstration of placing a cola, a clear soda, and a diet soda into a tank of water. Then let learners attempt to pour some of the soda into layers in a clear container. The procedure explains a thermocline, and...

Use science to solve the mystery of the Poplar murder. Pupils use forensic botany to determine if a suspect could be the killer. By analyzing images from a Transmission Electron Microscope, learners determine if the material found on the...

Model hardness testing with a self-designed hardness test. Young scholars rate the hardness of different types of aspirin using the Vicker's Hardness scale. They then relate hardness to the solubility of each aspirin tablet.

Can a good bug ever become a bad bug? An elementary entomology resource explores what to do when too many ladybugs or too many bees are in your home and can become a problem.

Over the course of 10 days, young scientists observe their cups of seed and soil—one that gets sun and water and one that gets no sun and only water. Then they reflect on the results of the experiment to determine if their hypothesis was...

Uncover the basics of DNA structure through exploration activities. Collaborative groups build DNA models and recreate the process of replication. Then, using plant cells such as peas or strawberries, they extract a DNA sample.

Explore the behavior of light waves with a lab activity. Scholars build new vocabulary through experimentation and observation. Using different mediums, they model reflection, refraction, transmission, diffusion, and scattering of light.

Practice electric vocabulary using multiple methods. Learners begin by watching a video that explains vocabulary related to electric currents. They match vocabulary cards to practice and then create an electric circuit. Using the...

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Stability is key when building a bridge. Scholars explore the forces acting upon bridges through an analysis of Newton's Laws and Hooke's Law. The activity asks individuals to apply their learning by building a bridge of their own.

Ecology aces examine sea surface temperature maps and relate temperatures to concentration in fish and zooplankton populations. Take your class to a computer lab and provide experience with actual remote sensing data. Some of the links...

View LED lights through the eyes of a scientist. Young scholars learn to view light as a wave frequency and connect various frequencies to different colors on the light spectrum. A lab activity asks groups to measure the frequency of...

Don't be shocked when your class has a blast making their own batteries! Science scholars examine a dry cell battery, then design and construct a wet cell battery. The activity guides them through the parts of a battery, the variables...

High schoolers are exposed to the variety of ways in which scientist use remote sensing and it used in everyday life. They investigate about zooplankton and fish. Students list the two important groups of organisms in both aquatic and...

Young entomologists discover insect anatomy in a very detailed unit plan. Offering background information for teachers about various insects, class members explore the differences between bugs and insects—and yes, there are many...

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for...

The size of a nanoparticle is difficult for pupils to grasp. A hands-on experiment is designed to give your classes perspective. Learners analyze different sports drinks for the content of electrolytes as an introduction to nanoscale....

Bridge the gaps in your knowledge of bridges. Individuals learn about bridge types by building models. The activity introduces beam bridges, arch bridges, truss bridges, and suspension bridges.

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

Eighth graders work together in groups to introduce themselves to the six types of simple machines. They are to record what the machine does, its mechanical advantage and identify real world situations in which they are used. They...

Students examine the case of a map making expedition. In groups, they read a case study on "The Lost Gorge" in the Finger Lakes region of New York state. They examine maps and determine where the error in the map-making occured to end...

Middle schoolers have years of experience when it comes to how their bodies work. Surely they have some questions as well. Here is an opportunity for them to practice the scientific method in an attempt to answer some of those questions....
