Proprioception is a sense of the body of its place and position in space - sometimes thought of as a sixth sense. In this activity, try some experiments that explore the unique functions of the body and brain.
In this experiment, two chemicals that can be found around the house will be mixed within a plastic baggie, and several chemical changes will be observed.
Have you ever enjoyed watching something lift off into the air, like fireworks at a show or a spacecraft launching? It can be an amazing experience. It is thrilling to see something lift off against Earth's gravity. To launch a spacecraft, its rockets give it a strong push that is due to a chemical reaction. This means that every time you see a spacecraft launch, you are watching chemistry at work. In this activity you will get to blast an object into the air using two simple ingredients -- baking soad and vinegar. Investigate how to mix these ingredients to get the best lift off, and then you could give your friends and family a homemade, gravity-defying show!

This lesson is a classroom activity where students learn to use their balance knowledge to create a beautiful mobile.
Have you ever seen a mobile? These are structures hang from the ceiling and are usually made up of many layers of rods to which differently shaped objects are attached with strings. When you look at the mobile sculpture, you might wonder how it can stay balanced all the time even when it is moving in the air.
This lecture/activity on force will further a students' understanding of forces on an object, as well as the difference between a balanced and unbalanced forces.
Students visualize and interact with concepts already learned, specifically algebraic equations and solving for unknown variables. They construct a balancing seesaw system (LEGO® Balance Scale) made from LEGO MINDSTORMS® parts and digital components to mimic a balancing scale. They are given example algebraic equation problems to analyze, configure onto the balance scale, and evaluate by manipulating LEGO pieces and gram masses that represent terms of an equation such as unknown variables, coefficients and integers. Digital light sensors, built into the LEGO Balance Scale, detect any balance or imbalances displayed on the balancing scale. The LEGO Balance Scale interactively issues a digital indication of balance or imbalance within the system. If unbalanced, students continue using the LEGO Balance Scale until they are confident in their understanding of solving algebraic equations. The goal is for students to become confident in solving algebraic equations by fundamentally understanding the basics of algebra and real-world algebraic applications.
On April 24, 1984, the Cleveland Museum of Natural History successfully hatched its first captive-bred eaglet. The years leading up to this milestone saw declining numbers of Bald Eagles in the wild—a consequence of the use of the pesticide DDT, as well as unregulated hunting. But our efforts helped to preserve this majestic species, which is now abundant throughout the state of Ohio and beyond. In this week’s Creature Feature, learn about Bald Eagles from Harvey Webster, the Museum’s Chief Wildlife Officer & Museum Ambassador. Worksheets available for grades PreK-K and 1-2.
This activity is a lab investigation where students design a balloon car to collect data about speed and velocity.
This activity is an extension of the common balloon cars, where students explore if and how different gases used as a fuel source effect the distances traveled by the cars.
Explore the behavior of electrons in conductors and insulators in this interactive simulation.
Make a balloon powered car out of recycled material
Engineer your own balloon-powered car.
Newton\'s Third Law states that for every action, there is an equal and opposite reaction. In this activity, you will use that principle to make a balloon powered pinwheel!
This activity enables students to apply concepts of 'newton's laws of motion' that are learned in class to a realworld situation by having them create a car powered by a deflating balloon that travels as far as possible.
This activity is a hands-on investigation that teaches students that air resitance affects how things move and that pressure from compressed air can move things.
In this structured inquiry activity students will work in groups/ teams to build a balloon rocket of their own design. The rocket will race in one dimension and require that they apply their knowledge of position, time, and velocity.
Students follow the steps of the engineering design process as they design and construct balloons for aerial surveillance. After their first attempts to create balloons, they are given the associated Estimating Buoyancy lesson to learn about volume, buoyancy and density to help them iterate more successful balloon designs.Applying their newfound knowledge, the young engineers build and test balloons that fly carrying small flip cameras that capture aerial images of their school. Students use the aerial footage to draw maps and estimate areas.
The purpose of this activity is to bring together the students' knowledge of engineering and airplanes and the creation of a glider model to determine how each modification affects the flight. The students will use a design procedure whereby one variable is changed and all the others are kept constant.
