In this activity, students investigate how increasing the surface area of a chemical increases its reaction rate. Students will compare the reaction rates when a whole antacid tablet and a crushed tablet are added to separate beakers of water.

In this STEM lesson, students will participate in an engineering design challenge to design and build a solar box cooker, and test it out to see if it works well enough to make S'mores.

In this STEM activity, students are enabled to demonstrate, test, and analyze materials utilized in spacesuits to keep astronauts cool in the harsh environment of space. They will demonstrate the water cooling technology used in the International Space Station (ISS) Extravehicular Mobility Unit (EMU). Students will also test and make an analysis of the relationship between reflection/absorption and color.

In this STEM lesson, students use the NASA Future Flight Design Challenge activity and website to help them learn how NASA engineers develop and test experimental aircraft to solve a specific problem by using the engineering design process. Students will solve an engineering design challenge based on specific criterion and build and design four paper aircraft based on actual NASA experimental aircraft. They will conduct and test their models and gather data of the results based on the design process and a specific challenge. Lastly, students will evaluate the performance of each aircraft based on engineering requirements.

In this lesson, students explore the Moon's habitability and sustainable resources with activities that culminate with plans for the design and creation of a lunar station.

In this STEM lesson, students follow the engineering design process to design and build a crane out of cardboard. They will determine methods to reinforce the crane's arms so it doesn't collapse under a heavy load. This activity is based on Robotics applications.

In this STEM lesson, students use balloons to demonstrate concepts applied by jet and rocket engines to supply thrust for movement. They will observe how unequal pressure creates power, explain how air power can help airplanes fly, and construct a working model of an air engine-balloon-powered rocket to launch the greatest payload possible to the classroom ceiling.

In this STEM lesson, students will construct three different kite models and predict the most effective design. They will design and test an aircraft given several parameters and explain how early flight was influenced by kites. This lesson uses the online NASA CONNECT: The "Wright" Math Educator Guide and the NASA Aeronautics Activity Guide; and the Sled Kite activity to help students learn how the Wright brothers developed controllable aircraft by understanding, constructing, and testing different designs.

In this STEM unit, students participate in an activity to grow plants in an environment very similar to the moon, which is designed in a unique partnership between NASA scientists and engineers and education professionals. The lesson incorporates leading-edge insight and practical experiences for students on how NASA works with plants. Students will describe the need for life science research on the International Space Station and the moon. They will also identify various plant species that are suitable for lunar plant growth and their requirements. In the culminating activities, students design and construct a working prototype of a plant growth chamber.

In this STEM activity, students will compare the aerodynamic features of different nose cone designs. They will experiment with different nose cone shapes to determine the advantages and disadvantages of each type. Conic, parabolic and flat shapes will be tested to determine which is most aerodynamic.

In this STEM activity, teams of students will form "rocket companies" and compete in a commercial endeavor to construct a rocket capable of lifting payloads into Earth orbit. Through a strong interdisciplinary approach, balancing science with technology, engineering and mathematics, they will develop a budget, purchase construction materials and track expenditures while designing the rocket. Students will apply principles and design, comstruct, test and launch a water rocket using a real-world problem-solving simulation.

In this STEM activity, students are challenged to solve a real-world problem that is part of the space program using creativity, cleverness, and scientific knowledge, while learning about forces, structures, and energy transfer. The goal is to construct a launcher that can withstand the force of repeatedly launching a one-kilogram bottle of water one meter into the air.

In this STEM activity, students use the engineering design process to build a structure to handle the greatest load. They also gain first-hand experience with compression and tension forces when they test the factors affecting the strength and stability of a structure. Using the design process, students will identify the problem, brainstorm, design, buiild, test, and share their solutions. Lastly, they will measure and record the strength and amount of weight the structure will hold.

In this STEM activity, students are challenged to solve a real-world problem that is part of the space program while learning about heat and heat transfer. Students will observe a design before and after testing, and pick out the-key features as they apply the design process to a problem. In the challenge, students will build a structure from aluminum foil and copper screening that will protect a model of the Ares launch vehicles from the heat of a propane torch for as long as possible. Students will document their designs with sketches and written descriptions. As a culmination students compile their results into a poster and present them to the class.

In this STEM lesson, students are challenged to create and test a water filtering system. The STEM activities in this lesson focus on water recovery and management. Students will design and build a water filtration device, test the device, make observations, and collect data. They will collaborate as they analyze results and attempt to idenity the best filter media to use. Based on their analysis and on study of other filtration devices, they will make modifications to their model and repeat the process in an effort to produce the most effective filtration apparatus possible. Lastly, students will compare individual results and communicate their results to the larger community.
