Erupting volcanos are a staple of many science fairs and school demonstrations. Plus they can be fun to do at home as well. But making the volcano canbe a bit frustrating. Either your make your own volcano with lots of Plaster-of-Paris and the mess caused by it, or a you buy a kit where you make a volcano with Plaster-of-Paris around a framework, or you have a pre-mold that ‘erupts’ using a squeeze bulb rather than a more interesting chemical reaction of vinegar & baking soda.
To help resolve this, the folks ar the Plasteel Corporation developed the Smoothfoam Mega Volcano:
For a couple of years we have been offering various wind gnereating kits such as the Savonius Wind Turbine. These kits do quite well but schools may find they need more to teach energy generation as part of a STEM program. So now Picoturbine offers multiple kits for Wind and Solar energy generation. There are several designs that depend on the size & design of the windmill (Mini, Standard, and Limitless) as well as the systems ability to generate AC, DC or both.
We finally have them in stock, the Dino Pet! The glowing, living dino-shaped pet!
Yeah, we could be called lazy today, but these are some great videos of some classroom products that we carry. Have a look:
The Orbiter. Either non-illuminated, or illuminated the Earth-Sun Orbiter models demonstrate how the Earth orbits our Sun, and how the tilt of the Earth’s axis causes the seasons:
The Economy Stream table is used in Earth Science classes to demonstrate how streams erode the land around them, causing them to make new paths and changing the landscape:
A big step up from the Economy Stream Table is the Hydro-Geology Stream Table. Much more versatile and able to demonstrate more erosion concepts.
The Teaching Tornado Model is an excellent way to demonstrate how these destructive weather forces form. Here it is in action:
The Celestial Star Globe is an excellent visual aid for showing how the Earth sits in space. The transparent globe shows the position of the Moon and the stars in space.
The always popular Orrery is a mechanical demonstration of how the planets orbit in out solar system. Students can get a real feel for how the outer planets ‘take their time’ in circling the Sun.
Oh hey, another Orrery video!
Teaching anything about human anatomy? You probably should get a Torso Model.
Are you interested in great science products for your classroom? We’ve got a wide variety!
Alternative energy is rapidly becoming one of the major topics of study in the classroom and Spectrum has supplied kits that produce energy via solar, hydrogen and wind. In that latter production category we have recently added a series of Savonius Wind Turbines and Windmill generators by PicoTurbine:
We recently added the Boogie Board, a LCD pad for drawing and writing.
The Boogie Board is an update of the classic ‘Magic Slate’ toy from the 50’s. Here you can use the stylus or even your own finger to draw on the screen. You can make lists, do math, draw pictures, and when you are done just push the button at the top of the Boogie Board and in a flash it wipes the screen clean! The Boogie Board can be wiped clean over 50,000 times on its included battery.
We have been adding more classroom items of late, and one of interest is the ‘What’s in the Soil’ kit from American Educational. The kit is large enough for 30 students to run tests.
Using ordinary soil, students perform test such as soil nutrient & mineral analysis (testing for over 10 nutrients & minerals) to determine the effectiveness of plant growth. Students also will determine water content, organic matter content & pH levels. Several soil samples are included in case local soil does not have enough variation.
The kit includes a 9 page teacher’s guide and covers 12 different activities. The kit is designed for students from grades 6-12 9age 11-18).
