This online board game involves moving a "research blimp" around the world. Advancing the blimp depends on spinning an embedded wheel and then correctly answering questions related to weather.
This article reviews the book "Using Science Notebooks in Elementary Classrooms" by Michael Klentschy and provides basic information about the role of notebooks in instruction and assessment.
This article features children's literature about scientists and scientific research in the Arctic and in Antarctica.
This activity is a forensic based physical science inquiry investigation where students collaborate in groups and use observations to determine how Newton's Laws of Motion are applied in finding evidence in a car and truck trailer accident. Their evidence will be used in a presentation to verify consistency in police and witness reports to support the plantiff or defendent in the court case.
Students use data acquisition equipment to learn about force and displacement in regard to simple and complex machines. In the engineering world, materials and systems are tested by applying forces and measuring the resulting displacements. The relationship between the force applied on a material, and its resulting displacement, is a distinct property of the material, which is measured in order to evaluate the material for correct use in structures and machines.
At first glance, starfish, more properly called sea stars, arenŰŞt doing much of anything. In this video, JonathanŰŞs investigations reveal a slow-motion predator that hunts and attacks its prey. Traveling the world, Jonathan investigates sea stars from the tropics to the Antarctic and uses time-lapse photography to reveal an amazing complexity to the world of the sea star. Please see the accompanying study guide for educational objectives and discussion points.
Cryptids, creatures of questionable existence, are used as a source of data to guide students into the creation of their own GIS data layer in Google Earth. The activity serves the purpose of a tutorial to teach students how to make data layers with a simple subject. Then they use that skill on other topics such as plastics in their neighborhood.
This worksheet provides a pair of satellite world maps, showing vegetation in January and July, and has a series of questions guiding exploration of the similarities and differences in the two images. The activity is from Space Update, a collection of multimedia educational resources about the Earth and Space. Summary background information, data and images supporting the activity are available on the Earth Update data site.
Explore your own straight-line motion using a motion sensor to generate distance versus time graphs of your own motion. Learn how changes in speed and direction affect the graph, and gain an understanding of how motion can be represented on a graph.
Semiconductors are the materials that make modern electronics work. Learn about the basic properties of intrinsic and extrinsic or 'doped' semiconductors with several visualizations. Turn a silicon crystal into an insulator or a conductor, create a depletion region between semiconductors, and explore probability waves of an electron in this interactive activity.
This module gives a comprehensive review of sensory disabilities and related assistive technologies.
This video features the remarkable discovery Jonathan made in 1998 about Basking sharks, the second largest fish on Earth. While diving with Basking sharks in the frigid waters of the Bay of Fundy, Jonathan saw parasitic lampreys on the backs of the sharks. This had never before been documented, so he returned the next year with a shark biologist and a lamprey biologist to attempt to recover living lampreys from the backs of Basking sharks. They didn't think Jonathan could do it. Wait until you see what happens! Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.
In the warm and blue waters off Hawaii, Oceanic White Tip sharks often follow behind pods of Pilot whales. For the longest time, biologists have had no idea what is going on. Are they eating the whales? Are they stealing food from the whales? In this video of an expedition to follow the sharks and observe them, Jonathan finally figured out what is going on, and you wonŰŞt believe the disgusting truth! Please see the accompanying study guide for educational objectives and discussion points.
This video features the Thresher shark, which may very well be the strangest looking shark in the world, with a tail almost as long as its body. This shark is very rare, almost never seen by divers...until now. Using advanced diving technology, Jonathan visits a remote reef in the Philippines where Thresher sharks show up every morning to be cleaned by small fish. Please see the accompanying study guide for educational objectives and discussion points.
In this video, filmed thirty miles off the coast of North Carolina, there is a shipwreck on the bottom, 130 feet down. Swarming around the wreck are dozens of Sand Tiger sharks. They look menacing, but they seem to be very docile. What are they all doing there, in one spot? That's what Jonathan wants to find out. Using a variety of filming techniques, Jonathan attempts to discover the secrets of the Sand Tiger shark gatherings at the wrecks, and does the first ever night dive with these shark..talk about scary! Please see the accompanying study guide for educational objectives and discussion points.
In this video from Science City, Shaundra Bryant Daily, an electrical engineer, describes a software program she developed to help girls reflect on their emotions, and how her two passionsí_í_íŹscience and danceí_í_íŹare connected.
Students apply the mechanical advantages and problem-solving capabilities of six types of simple machines (wedge, wheel and axle, lever, inclined plane, screw, pulley) as they discuss modern structures in the spirit of the engineers and builders of the great pyramids. While learning the steps of the engineering design process, students practice teamwork, creativity and problem solving.

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.
In this video segment adapted from NOVA scienceNOW, learn about engineering innovations that could help detect a bridge's structural weaknesses before they become dangerous.
