Your class will use a set scale to convert diameters of planets to the model size, the diagram given to expand on the number of planets drawn as concentric circles, and examine the scale that would be needed to fit the larger...

Although the article that launches this lesson is about the history of the Periodic Table, the objective is reading comprehension. Using the eight-page informational text, learners answer five comprehension questions and craft one essay....

Gummy bears are tasty, but did you know they are also used to determine color and light properties? Use the activity as a way to demonstrate light absorption, light reflection, and refraction with high schooler....

Density: the reason a giant pumpkin will float, but a tiny cranberry won't. Lesson begins with a demonstration of two of the same-sized cubes having different densities. Then pupils take eight cubes, each of the same size, and have to...

Students examine the use of a sundial to tell apparent time. In this sundial instructional activity, students watch a teacher demonstration using a flashlight to create shadows. They discuss what happens to shadows of different objects...

Brief, but beneficial, this little gem displays the workings of a hydrogen fuel cell. A simple black-line diagram has question marks at the input and the output, as well as in the middle of the cell. Click on each question mark to reveal...

Here you'll find a great sampling of practice standardized test questions organized into four sections: ELA, mathematics, social studies, and science. Help your learners become familiar with the types of multiple-choice questions...

The propellant needed for space explorations runs in the thousands, while paying to get the craft into orbit costs millions! In the second installment of three, two activities explore laws of conservation of energy and momentum. Using...

Meet me in the tunnels. Scholars choose a tunnel entrance and mark it on their side of the cardboard. They describe the location to their partners and see if they can guess each other's locations. Punching a hole through the cardboard...

Properties of water make it essential for the life of marine species. Learners complete an online game to answer questions about the role water fulfills for organisms in ocean habitats. The game emphasizes the properties of water and how...

Questions that can be used in a lesson on Earth's radiation balance are suggested in this resource. It is not a lesson plan, per se, but it is a list of questions for stations within a "Gallery Walk" lesson. The link to how Gallery Walks...

A Gallery Walk is a technique that allows small groups to visit different stations, where they examine and discuss materials about an overarching topic. Questions about rivers and fluvial processes are available in this resource;...

In an introductory lesson, youngsters take a pre-assessment quiz, get a grasp of a gram of mass, and then estimate the mass of microorganisms that live within a human body. Using Glo Germ™, a material that allows you to simulate the...

Grizzly bears can be up to 600 pounds and require a great deal of food, especially to survive hibernation. Comprised of multiple games, the third lesson of five only uses one setup. Pupils run around a large field, sorting and collecting...

Life science learners need to be able to use a microscope. With this comprehensive resource, they first experience how lenses and magnification work, and then get familiar with using a compound microscope. Tremendous background...

Young scientists design a rocket to launch using Newton's Laws of Motion in order to discover for themselves the forces of motion. 

Feet are neat! So, if you've already walked the path of examining animal footprints with your class, put them in the shoes of early humans! A well-designed lesson incorporates video, discussion, and hands-on learning to demonstrate how...

Human body systems learners play a card game, "Locks & Keys" in order to learn that neurotransmitters carry a message from one neuron to another by fitting into a receptor site on the receiving nerve cell. While this activity can...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Designed to use when teaching adults preparing for their high school equivalency exam, the resource integrates reading practice, writing, and analytical thinking in every lesson. The unit covers 23 topics, but it only includes three...

Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...

Several times throughout history, groups of soldiers marching in rhythm across a suspension bridge have caused it to collapse. Scholars experiment with pendulums, resonance, and force to determine why this would happen. First, pupils...

Six pages begin with a detailed introduction to meiosis and homologous chromosome pairs. Instructions guide learners through a simulation in which they draw craft sticks marked with autosomes in order to decode the genes inherited by...

Young climatologists explore the factors that contribute to a region's climate in this two-part earth science activity. To begin, learners are provided with a map of an imaginary planet and are asked to label global wind and...
