In this activity students will learn the basic concept of Global Positioning Systems (GPS) using triangulation and measurement on a small scale in the classroom. Students discover how GPS and navigation integrate mathematic and scientific concepts to create a standard for locating people and objects. This activity helps students understand both the need for and methods of navigation.
Energy of Motion
By taking a look at the energy of motion all around us, students learn about the types of energy and their characteristics. They first learn about the two simplest forms of mechanical energy: kinetic and potential energy, as illustrated by pendulums and roller coasters. They come to understand that energy can change from one form into another, and be described and determined by equations. Through the example of a waterwheel, the concepts of and differences between work and power are explained an
This unit teaches students how and why engineers design satellites to benefit life on Earth as well as allows students an opportunity to explore motion, rockets and rocket motion. Students discover that the motion of all objects including the flight of a rocket and even the movement of a canoe is governed by Newton's three laws of motion. Space exploration is a huge consideration for aerospace engineers, and this unit introduces students to the challenges of getting into space for the purpose of
Normally we find things using landmark navigation. When you move to a new place, it may take you awhile to explore the new streets and buildings, but eventually you recognize enough landmarks and remember where they are in relation to each other. However, another accurate method for locating places and things is using grids and coordinates. In this activity, students will come up with their own system of a grid and coordinates for their classroom and understand why it is important to have one co
Students will use two different methods to determine the densities of a variety of materials and objects. The first method involves direct measurement of the volumes of objects that have simple geometric shapes, while the second uses the water displacement method to determine the volumes of irregularly-shaped objects. After the densities are determined, students will create x-y scatter graphs of mass versus volume, and these graphs will reveal that objects with densities less than water (floater
Does Your Chewing Gum Lose Its Flavor?
In the first part of the activity, each student chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days before weighing it to determine the amount of mass lost. This mass corresponds to the amount of sugar in the gum, and can be compared to the amount stated on the package label. In the second part of the activity, students work in groups of four to design and conduct new experiments based on questions of their own choosing. These questions arise naturally
Students will conduct a simple experiment to see how the water level changes in a beaker when a lump of clay sinks in the water and when the same lump of clay is shaped into a bowl that floats in the water. They will notice that the floating clay displaces more water than the sinking clay does, a result that will probably surprise them. They will then determine the mass of water that is displaced when the clay floats in the water. A comparison of this mass to the mass of the clay itself should r

Children Learn Zoo Animal Names Quickly in Spanish
In this video, students will learn various zoo animal names in Spanish. An animated picture of the zoo animal is shown with the Spanish name and then a real photograph is shown. This is a fun teaching resource for a lesson/unit on zoo animals in the elementary classroom. (3:42)
Physics of Roller Coasters
Students explore the physics utilized by engineers in designing today’s roller coasters, including potential and kinetic energy, friction, and gravity. First, students learn that all true roller coasters are completely driven by the force of gravity and that the conversion between potential and kinetic energy is essential to all roller coasters. Second, they also consider the role of friction in slowing down cars in roller coasters. Finally, they examine the acceleration of roller coaster cars
Students are introduced to the concept of energy cycles by learning about the carbon cycle. They will learn how carbon atoms travel through the geological (ancient) carbon cycle and the biological/physical carbon cycle. Students will consider how human activities have disturbed the carbon cycle by emitting carbon dioxide into the atmosphere. They will discuss how engineers and scientists are working to reduce carbon dioxide emissions. Lastly, students will consider how they can help the world th
Heat It Up!
Through a teacher demonstration using water, heat and food coloring, students see how convection moves the energy of the Sun from its core outwards. Students learn about the three different modes of heat transfer (convection, conduction, radiation) and how they are related to the Sun and life on our planet.
To understand how fossils are formed, students model the process of fossilization by making fossils using small toy figures and melted chocolate. They extend their knowledge to the many ways that engineers aid in the study of fossils, including the development of tools and technologies for determining the physical and chemical properties of fossilized organisms, and how those properties tell a story of our changing world.
By making and testing simple balloon rockets, students acquire a basic understanding of Newton’s third law of motion as it applies to rockets. Using balloons, string, straws and tape, they see how rockets are propelled by expelling gases, and test their rockets in horizontal and incline conditions. They also learn about the many types of engineers who design rockets and spacecraft.
The Science of Swinging
Students learn what a pendulum is and how it works in the context of amusement park rides. While exploring the physics of pendulums, they are also introduced to Newton’s first law of motion — about continuous motion and inertia.
Students are introduced to our Sun as they explore its composition, what is happening inside it, its relationship to our planet (our energy source), and the ways engineers help us learn about it.
Using a Fancy Spectrograph
Students use the spectrograph from the “Building a Fancy Spectrograph” activity to gather data about different light sources. Using the data, they make comparisons between the light sources and make conjectures about the composition of these sources.
