August 21, 2017. Be ready for the American eclipse, a total eclipse of the sun visible from sea to shining sea just when school is starting. This 32pp booklet is written by astrophysicist Fred Espenak. Full of fascinating facts and time charts for cities across North America, plus a map of the eclipse’s path. Includes a pair of cardboard-frame solar viewing glasses.
Why watch the 2017 total eclipse of the sun (or any eclipse or sunset) with cardboard glasses? Your fashion-forward astronomy geeks will be wearing these ISO standard 12312-2 solar-viewing eClipser-HD™ glasses. Vaguely Star-Trekkish, they have scratch resistant polymer lenses that show the sun in a natural orange and block 100% UV and 99.999% of visible light, black plastic frames and come in a protective carrying pouch.
If the question is whether to tie a bunch of these giant latex professional weather balloons to a lawn chair, the answer is no. (They burst at about 82,000 feet anyway.) Besides, this is a true weather balloon, with plenty of fun, nonfatal uses. The cream-colored latex balloon is approx 40" dia when flaccid, you should pardon the expression, but has an 8-foot dia when inflated. The neck is 9" long x 1" dia. Scientists, meteorologists, inventors, teachers and the imaginative filmmaker are warned to launch the balloon carefully. The material is delicate and not made to survive brushes with pavement, pine branches, or clumsy physics students.
Blow up this big, 8-foot long x 2-foot dia, solar balloon on a sunny day and then sit there, maybe enjoying a refreshing beverage, and watch while the sun heats up the black surface and the air inside expands and becomes lighter than the surrounding atmosphere and the whole thing rises like your hopes for a bright future. Includes a 20-foot cord to keep it in check. Works best on a cool but bright day. Don't we all.
Nice little teaching magnet set for the primary grade classroom has (6) magnets in star, two-bar, horseshoe and ring shapes, all plastic coated in silver and red to mark the poles. Range in size from 1” to 3”, and include a few paper clips and small nails for demo purposes.
They might as well learn something while they're trying to outlast you
on eating those lima beans. Set the table with educational placemats and
they'll be at least a touch smarter after dinner, even if their
vegetable intake is low. These laminated, 12" x 17-3/8" mats have
full-color fronts, black-and-white backs. Choose the United States Map,
Stars & Constellations, the Periodic Table of Elements or The Metric
All you add is sunlight to use this 50-foot long solar balloon to prove that Bernoulli was right. Pascal, too. Demonstrate buoyancy, convection, thermodynamics and the power of the sun. Measures 29" dia and comes with 400 feet of string, and instructions.
Put the world on a desktop with these 4" dia swivel-and-tilt globes. You pick from: the topographic globe with country borders and names or the antique-style political globe that shows current countries but in earth tones without topographic details. Both have vertical and horizontal axes and stand on a 3-inch base. Made in Germany.
