In this demonstration, students detect the interference of waves and measure wave phenomena using an experimental apparatus consisting of a laser pointer, a second surface mirror scrap (like a bathroom mirror) binder clips, razor blade, ruler, and a white wall or projection screen. Appendices with a discussion of physical principles and extension activities are included. 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.

This is lesson to begin learners' thinking about magnetic influence. Learners will watch a classroom demonstration about the effect of magnets on iron filings and then complete a journal assignment to record their reactions and thoughts. This is the first activity in the Mapping Magnetic Influence educators guide.

This demonstration is designed to show how the inputs and outputs of energy or mass in a system balance. Students create a reservoir model using a hose, a bucket, a tub with a drain and overflow triangle, a ruler, and water, to understand the inputs and outputs of a local watershed or reservoir. A worksheet accompanies the activity. The resource is supported by teacher background information, assessments, and a scoring rubric. This is Activity 1 of the learning module, Global Balance, part of the lesson series, Potential Consequences of Climate Variability and Change.

In this activity, students investigate the interacting parts of the Earth system by observing changes in evaporation rate in four small aquariums with different initial conditions. The demonstration requires 4 small aquariums, soil, plants, water, graduated cylinder, scale, plastic wrap, and colored pencils. A student data sheet is included. The resource is supported by teacher background information, assessment suggestions, and a scoring rubric. This is Activity 3 in the learning module, Global Balance, part of the lesson series, The Potential Consequences of Climate Variability and Change.

In this pen and pencil activity, student teams use an inquiry approach to create their own model of the hydrological cycle. A calculator is needed for this activity. Teacher background information, assessment suggestions, and a scoring rubric are included.This is Activity 4 of the learning module, Global Balance, part of the lesson series, The Potential Consequences of Climate Variability and Change.

This fact card discusses the shape of space and how light is affected by the amount of dark matter and energy in the universe. MAP's microwave detection gives us enormous insight into the creation of this matter and energy. Note: this resource was published prior to the mission name change from MAP to WMAP (Wilkinson Microwave Anisotropy Probe) to honor Dr. Wilkinson.

The purpose of this resource is to investigate the center pixel of a homogeneous land Cover Site in order to understand that individual land areas are part of a larger land system.

The purpose of this resource is to investigate the idea that every dynamic system has energy and matter in different forms.

In this hands-on activity, students learn about the different realms of the Universe and explore their sizes and relative scales. They will be guided through a process that uncovers the immense sizes of the Sun, Solar System, Solar Neighborhood, Milky Way, Local Group, Supercluster, and the observable Universe. The full version of this activity involves students doing simple math computations, however it can also be done without the math. There are some inexpensive materials involved, as well as a powerpoint presentation. It is intended for grades 8-12, but can be adapted down for lower grade levels.

In this hands-on activity, learners begin by estimating the size of each planet in our Solar System and Pluto and making each out of playdough or a similar material. Then, learners follow specific instructions to divide a mass of playdough into the size of each planet and Pluto and compare the actual modeled sizes to the students' own predictions. This activity requires a large amount of playdough material per group of learners. Three pounds is the minimum amount required for each group.

This is an activity about the electromagnetic spectrum and how the different wavelengths of light are used to capture the most complete picture of objects in space. Learners will view images of our galaxy in multiple wavelengths to compare and analyze what is seen. This activity requires a computer with Internet access, and is Astronomy Activity 3 in a larger resource entitled Space Update.

This activity is about rocket shape and performance. Learners will test a rocket model and predict its motion. They will launch their rocket multiple times, make observations and record the distance it traveled. They will have the opportunity to answer a research question by collecting and analyzing data related to finding out the best nose cone length and predicting the motion of their model rockets. The lesson models the engineering design process using the 5E instructional model and includes teacher notes, vocabulary, student journal and reading.

This video provides step-by-step instructions for collecting soil samples in the field, and for analyzing and storing soil samples in the lab. Procedures for determining the bulk density, particle density, particle size distribution, fertility, and pH of a soil are demonstrated. The resource includes a video and a written transcript, and is supported by the Soil Characterization, Lab Measurement Protocols in the GLOBE Teacher Guide. This is one of five videos about soils in the 24-part instructional video series describing scientific protocols used by GLOBE (Global Learning and Observation to Benefit the Environment) a worldwide, hands-on, K-12 school-based science education program.

This is a promotional folder for Sun-Earth Days 2013, containing images and illustrations of the Sun and its effects on the Solar System. Also included is information about the period known as solar maximum, as well as links to Sun-Earth Day resources and the Space Weather Action Center.

This is an activity involving observations of the Sun. Learners use pinhole cameras, solar telescopes, and/or solar viewing glasses to make solar observations, draw what they see, and identify sunspots, if they are present. Then, learners go online and compare their drawings to images obtained by the SOHO spacecraft. This activity requires the use a sunny outdoor location. This activity also require use of safe methods for observing the Sun, such as pinhole cameras, telescopes with proper solar filters attached, and/or viewing glasses that are designated for safe solar viewing. No one should look at the Sun unless one or more of these methods is used in a proper fashion.

This activity is about planetary distances. Learners will create a model of the solar system using beads and string, and compare planetary sizes using common types of fruit and seeds. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes and vocabulary.

This is a reading associated with activities during Solar Week, a twice-yearly event in March and October during which classrooms are able to interact with scientists studying the Sun. Outside of Solar Week, information, activities, and resources are archived and available online at any time. This is a blog entry about the process by which rocket payloads are assembled prior to launch. It was written by one of the female team members associated with a NASA sounding rocket launch program. The blog entry reading is scheduled to occur during Friday of Solar Week.

This is an online lesson associated with activities during Solar Week, a twice-yearly event in March and October during which classrooms are able to interact with scientists studying the Sun. This activity is scheduled to occur during Monday of Solar Week. The lesson introduces the concept of astronomical filters and their connections to imaging different objects in space. Learners will explore perceptions of images as seen using different colors of light, construct a filter wheel, and practice investigating various astronomical images using the filter wheel. This material was designed to highlight how filters are useful to astronomers and show how a real astronomical telescope uses filters to image the Sun. Outside of Solar Week, information, activities, and resources are archived and available online at any time.
