To conclude a study of A Raisin in the Sun and to prepare for a visit to the Lewis Museum, class members analyze Langston Hughes' poem "Harlem." Learners then draw connections to characters in the play and to their own experiences...

Learners design an investigation using yeast. In this environmental engineering instructional activity, students design an investigation to determine how environmental factors affect the growth of yeast. They will collect quantitative...

Middle schoolers examine the world of the Arkansas alligator and topics that are related to wetland environments. They pay attention to the relationship between geography, climate, environment, and the animals who live there. A role-play...

Keep everything under control. The lesson, the 16th segment in a 22-part unit, provides a more detailed look at the parts of a plane, specifically the control surfaces. Pupils learn about the construction of the wings and the tails and...

Upper graders analyze basic concepts about the consumption, importation and exportation of the worlds oil production. They create several graphs to organize the data and draw conclusions about the overall use of oil in the world.

Bend it, but don't break it. Groups investigate the strength of different materials. Using a procedure in the seventh segment of a 22-part series on aviation, pupils determine how far a rod will bend. They determine the strength-to-mass...

Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Help your class understand the design challenges when trying to land a remote spacecraft on a planet. Class members examine the provided information to understand how each component of a spacecraft is designed in order to safely land a...

Students examine aesthetic movement known as modernism, discover why organizers chose modernism as World Fair's design pattern, interpret photographs of modernist fair buildings and identify artifacts that reflect modernist ideas, and...

Do not let the pressure get to you. The first instructional activity in a unit of 22 introduces the concept of air pressure. Using background knowledge, the resource gives teachers the information they need to discuss how people measure...

Get the class up and going with a instructional activity that discusses how airplane wings provide lift. Pupils use their knowledge of Bernoulli's Principle to develop an explanation of how it creates lift on airplane wings.

To go or to not to go — the question for a mission to Mars. This resource provides details for a possible manned mission to Mars. Details include a launch schedule, what life would be like on the surface, and how the astronauts would...

Students recognize that compression and tension forces are important considerations in building structures. They construct their own building structure using marshmellows and spaghetti to see which structure can hold the most weight.

Investigate what is pushing on us. An intriguing lesson has pupils calculate the amount of force on various squares due to air pressure. Using the data, individuals create a graph in the third lesson of the Up, Up and Away unit...

Get out the goggles and conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects. Young chemists observe and describe the harmful...

Students create a working radio by soldering circuit components supplied from an AM radio kit. They demonstrate an efficient soldering technique, identify the circuit components used to construct their radio, and explain how their radio...

Students investigate different balls' abilities to bounce. They conduct a Ball Bounce Height Comparison and Ball Bounce Time Comparison, complete a worksheet, graph the results of their experiment, and answer investigating questions.

Students design a proportional model of blood out of red gelatin, a plastic bag, and rice. They study the components that make up blood and investigate what happens when the arteries in different scenerios. They work in pairs in order to...

Young scholars design a skydiver and parachute constraption to demonstrate how drag caused by air resistance slows the descent of skydivers as they travel back to Earth. They experience how gravity pulls the skydiver toward the earth and...

Learners study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur during low...

Students read the story, Dear Mr. Henshaw. They build an alarm system for something in the classroom, as the main character Leigh does to protect his lunchbox from thieves. Students explore alarms and use their creativity to create an...

Middle schoolers participate in an activity that replicates the creation of sea floor bathymetry by taking a simplified form of soundings in the classroom. They discuss sea floor mapping technologies, sonar, soundings, and remote...

Students make Moebius strips and use them to demonstrate the interconnectedness of an environment. They explore the natural cycles (water, oxygen/carbon dioxide, carbon, nitrogen) within the environment. They describe how the cycles are...

Using their knowledge of right triangles, pupils find out how far a ship is from a light house. Class members determine how far around the world a ship would be sailing at a constant speed.
