In this activity, students create their own cumulus cloud out of white paper and mount it on blue paper. Students will also complete the Cloud Fun Student Activity Sheet that includes a description of the cloud and what the weather was like on the... (View More) day the cloud was observed. Uses commonly available or inexpensive materials (blank wall chart paper, newspaper, construction paper, glue, markers or pencils). This is the 1st of 3 sets of learning activities that are companion activities to the Elementary GLOBE children's book, *Do You Know That Clouds Have Names?* Includes a teacher implementation guide.

Each student will make predictions about the properties of various soil samples. Then they will examine several types of soils and record their observations. Next, they will learn about soil profiles and horizons by both examining a soil sample in a... (View More) jar and by creating a soil profile flip chart. Uses commonly available or inexpensive materials (e.g., soil samples, mesh wire strainers,tweezers, toothpicks eye droppers, magnifying glass, rulers, water, colored pencils or crayons). This is the 1st of 3 sets of learning activities that are companion activities to the Elementary GLOBE children's book, The Scoop on Soils. Includes a teacher implementation guide. (View Less)

Students will use various objects in the classroom to experiment with nonstandard measurement. They will make estimates and test them out. Then, working in pairs or small groups, students will use a ruler or a measuring tape to become familiar with... (View More) how to use these tools for standard linear measurement. Uses commonly available or inexpensive materials (metric ruler, plant seeds, soil, containers). This is the first of three sets of learning activities that are companion activities to the Elementary GLOBE children's book, Discoveries at Willow Creek. Includes a teacher implementation guide. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (View Less)

Students will learn about magnification and how a magnifying lens works. They will examine a variety of different objects, first without a magnifier and then with a magnifier, and compare what they observe. They will practice observing details of...

Then, working in pairs or small groups, students will use a ruler or a measuring tape to become familiar with how to use these tools for standard linear measurement. Uses commonly available or inexpensive materials (magnifying glass, construction paper, scissors,salt and sugar, crayons or chalk). This is the 2nd of 3 sets of learning activities that are companion activities to the Elementary GLOBE children's book, Discoveries at Willow Creek. Includes a teacher implementation guide.

This demonstration shows that similar-appearing lights can be distinctly different, suggesting that the light emitted is generated in different ways. It requires some advance preparation/setup by the teacher and three recommended sources of orange... (View More) light, that can be purchased at a hardware or department store. Includes extensions and additional background information on light generation in a section on underlying principles. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

In this activity, students compute the strengths of the gravitational forces exerted on the Moon by the Sun and by the Earth, and demonstrate the actual shape of the Moon's orbit around the Sun. The lesson begins with students' assumptions about the... (View More) motions of the Moon about the Earth and the Earth about the Sun, and then test their understanding using an experimental apparatus made from a cardboard or plywood disk and rope. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

In this demonstration, students experience the Doppler effect for sound. Students can compute the frequency change for motion along the line of sight (LOS) and determine the vector LOS component for motions not exactly on it. A buzzer, battery,... (View More) bicycle wheel, string and a rubber ball and a timer are needed for the demonstration. The resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

This activity lets students measure distances in the classroom using parallax. The exercise can be done either at a high school level using trigonometric functions, or at a middle school level using simple arithmetic approximations to the... (View More) trigonometric functions. A work sheet is provided for the middle-school-level activity.The resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

Students will work in teams to create visual models to assist in understanding the volume of surface ozone in the air. Students construct cubes of different volumes and compare them to get a feel for parts per million by volume and parts per billion... (View More) by volume. Resource includes a paper template for creating the cube and a student worksheet. This is a learning activity associated with the GLOBE Atmosphere investigations and is supported by the Atmosphere chapter of the GLOBE Teacher’s Guide. (View Less)

In this short demo/activity, a balloon with baking soda in it is stretched over the mouth of a flask or bottle containing vinegar. The balloon is tipped so that the baking soda falls into the vinegar, and the reaction creates carbon dioxide, which... (View More) inflates the balloon. The activity is part of the children's book, The Air We Breathe. (View Less)
