This resource describes the physics behind the formation of clouds, and provides a demonstration of those principles using a beaker, ice, a match, hot water, and a laser pointer. This resource is from PUMAS - Practical Uses of Math and Science - a...

This activity demonstrates Newton’s Second Law (F=ma), and helps show the relationship between potential and kinetic energy. Students sit on a skateboard in a sling shot configuration, and are accelerated down the hall. Potential energy from the... (View More) inner tubes (sling shot) is converted into kinetic energy. Materials required for the demonstration include 10 bicycle inner tubes, a helmet, skateboard, stopwatch, and a spring scale. Formulas and a worksheet are provided. The investigation supports material presented in chapter 1, "What is energy?" in the textbook Energy flow, part of Global System Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.

In this demonstration, evidence of the Earth's rotation is observed. A tripod, swiveling desk chair, fishing line and pendulum bob (e.g., fishing weight or plumb bob) are required for the demonstration. This resource is from PUMAS - Practical Uses...

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... (View More) these objects with a magnifying lens. 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 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. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (View Less)

This experimental activity is designed to develop a basic understanding of the relationship between temperature and pressure and that a barometer can be constructed to detect this relationship. Resources needed to build a simple barometer include a... (View More) canning jar with metal lid ring, large balloon, a block of wood, ruler, a nail, wood glue, hammer and a screwdriver. The resource includes background information, teaching tips and questions to guide student discussion. This is chapter 6 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The guide includes a discussion of learning science, the use of inquiry in the classroom, instructions for making simple weather instruments, and more than 20 weather investigations ranging from teacher-centered to guided and open inquiry investigations.

Materials Cost: $1 - $5 per group of students

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)

Materials Cost: 1 cent - $1 per group of students

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.

In this inquiry investigation, students conclude that the motion of the Earth is linked to the changes we observe such as the length of the day. Students learn about the reason behind the Earth's time zones. An optional water clock and sand clock... (View More) making activity supports this investigation. This is the eighth of 10 inquiry investigations in Threads of Inquiry: Observing the World Around Us. Each lesson includes teacher background information, a narrative that models and describes the inquiry process applied in the lesson, and a hands-on inquiry investigation. Literacy extensions and a non-linguistic pre- and post-assessment are also included. (View Less)
