Tropical fish are a great subject for any art project, they are colorful, interesting, and can go along with under water themed stories read in class, learner written narratives, or Marine Biology units. This set of instructions will...

Conduct research focused on improving a current technology by having students work in groups to investigate improvements that could be made to a particular piece of technology. They list the current problems and attempt to develop...

Can you solve an equation graphically? Absolutely! This Algebra II lesson plan makes the connection between solving an absolute value equation and graphing two functions. Graphing absolute value functions is presented through the process...

Class members discover what it means to publish their works. Working on a computer, young writers use an online dictionary to edit their spellings and conventions based on the information added to the rubric. From here, and most of the...

Ever played 20 Questions? A similar game helps young learners practice asking and answering yes-or-no questions. Spread out several objects, preferably all similar with slight variations (buttons or coins would work well). A leader...

Students set up working models demonstrating lake turnover and the formation of deep water masses in the oceans.

Physical or life science learners measure the amounts of water eliminated by intestines and the urinary system, and the amounts lost via respiration and perspiration. In doing so, they discover that the body's water must be replenished...

Students complete a Sudoku puzzle using their math skills. After listening to the rules of Sudoku and observing a demonstration, students use the process of elimination and other methods to complete puzzles. They explore how the...

Compression, the process computers use to store information, is the focus of a resource that presents two different stories that describe the concept of compression by eliminating repeated letters and replacing them with a...

Students solve a system of two unknowns.  In the Algebra instructional activity, students use a on line computer applet/program to solve a system by the elimination method.  The student's work is self checking, giving immediate...

Although designed for the Canadian War Museum, the concept here is a solid one. Class members select an artifact from the First World War, examine it, research it, and craft an explanative label that they attach to their picture and post...

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.

Students reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.
