This activity introduces Geographic Information Systems (GIS) and poses questions that help students answer questions that require spatial data. Students examine questions about communities and populations from local to state to national scales. Six GIS, math and mapping activities are identified in this resource. 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.

Students will use GeoMapApp to investigate variations in the geomorphology of continental margins -- both Passive and Active -- at various sites of the North American and South American continents. They will then construct a table of observations that will relate margin geomorphology and seismic activity, followed by general interpretations for the causes of the variations observed. Even if students are already familiar with Plate Tectonics and know the associations among plate boundaries, seismic activity and continental margin geomorphology, they will practice developing their observation skills for comparative analyses and interpretations.

This is a lesson about using evidence to construct sequences of geologic events. Learners will interpret real NASA science data to identify features on the surface of Mars, determine the surface history of the area, calculate the size of features, and develope investigable questions. Students will study images taken by NASA's Mars Thermal Emission Imaging System (THEMIS) camera orbiting Mars. Students will use the THEMIS images to analyze the surface features and geological history of Mars. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes and vocabulary.

This article explores how statistics can be interpreted in different ways to yield different conclusions. It describes the outcome and discussion of two class activities. In the first, the results are interpreted to "show" that taking a group rather than an individual perspective is ultimately beneficial to the individual. In the second, a variation is added "showing" that telling the truth is better that lying. 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.

Students learn how volume, viscosity and slope are factors that affect the surface area that lava covers. Using clear transparency grids and liquid soap, students conduct experiments, make measurements and collect data. They also brainstorm possible solutions to lava flow problems as if they were geochemical engineers, and come to understand how the properties of lava are applicable to other liquids.

Students are introduced to the concept of light pollution by investigating the nature, sources and levels of light in their classroom environment. They learn about the adverse effects of artificial light and the resulting consequences on humans, animals and plants: sky glow, direct glare, light trespass, animal disorientation and energy waste. Student teams build light meters using light sensors mounted to LEGO® MINDSTORMS® NXT intelligent bricks and then record and graph the light intensity emitted in various classroom lighting situations. They are introduced to the engineering concepts of sensors, lux or light meter, and lumen and lux (lx) illuminance units. Through this activity, students also learn how to better use light and save energy as well as some of the technologies designed by engineers to reduce light pollution and energy waste.

This activity is a field investigation where students measure, record and describe weather conditions using common tools (rain gauge, thermometer, and barometer). They will compare their observations to Weather.com (online) and the local newspapers to compare their findings, and record these observations.

In an interview, a zookeeper at the Columbus, Ohio, polar bear exhibit describes time she spent at Churchill, Manitoba, educating tourists about polar bears and what can be done to help populations in the wild. This interview appeared in the free, online magazine Beyond Penguins and Polar Bears.

Meiosis is the process by which gametes (eggs and sperm) are made. Gametes have only one set of chromosomes. Therefore, meiosis involves a reduction in the amount of genetic material. Each gamete has only half the chromosomes of the original germ cell. Explore meiosis with a computer model of dragons. Run meiosis, inspect the chromosomes, then choose gametes to fertilize. Predict the results of the dragon offspring and try to make a dragon without legs. Learn why all siblings do not look alike.

Monitor the temperature of a melting ice cube and use temperature probes to electronically plot the data on graphs. Investigate what temperature the ice is as it melts in addition to monitoring the temperature of liquid the ice is submerged in.
This formative assessment item uncovers student ideas and misconceptions about melting icebergs. …
This formative assessment item uncovers student ideas and misconceptions about melting icebergs. It determines if students believe that water levels will rise due to melting icebergs. Resources provided will assist teachers. It gives instructional support as well as information for teachers. This probe is aligned to National Science Education Standards (NSES).

In this activity, students learn about the advantages of the metric system, by comparing the ease of calculation and conversion between the English and metric systems of measurement. 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.

Deep underneath MexicoŰŞs Yucatan peninsula, underground rivers wind their way to the sea. In some places, the forest floor has fallen in, leaving holes in the ground to access these mysterious underwater caves. The holes, called cenotes, were considered openings to the underworld by the ancient Mayans. In this video, Jonathan teams up with an expert cave diver to explore these spooky underground rivers. Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.

This group learning activity involves students in an engaging review of concepts of microbiology. The review is set up as a power point presentation in the style of the "Jeopardy" gameshow where students groups compete against each other to answer review questions.

In this geology activity, students investigate the physical property of mineral cleavage by physically trying to break down a block of halite and describing the results. This lab addresses many misunderstandings non-majors have about the physical properties of minerals and includes a brief write up of their conclusions.

Students are each given a mineral and asked to locate all other students in the room with the same mineral (knowing there are a total of 5 different minerals). Once groups form, they need to decide what characteristics are similar for all their samples and ultimately report out to the whole class on their observations.

This module introduces students to minerals, crystals, and gems by using pictures and discussions of some of the extraordinary specimens residing in the collections of the Smithsonian Institution. It includes three lessons in which they draw pictures of specimens, grow their own crystals of magnesium sulfate, and perform a scavenger hunt in which they look for minerals in commonly used objects and products.
