Just Some Cool Videos Of Awesome Classroom Science Stuff

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!

John Dobson, developer of the Dobson Telescope and tireless advocate of amateur astronomy, R.I.P. 1/15/14

We were saddened to hear that John Dobson passed away on Saturday, January 15th, 2014 at the age of 98.

Dobson is most famous for building, developing and promoting a design of reflector telescope that still bears his name: The Dobsonian Reflector Telescope, one of the most popular telescope mounts on the market today. Dobson never laid any claim to the design that bears his name and never made a dime from them.

PicoTurbine Wind Turbine Classroom Kits

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:

Shake it up! The BenchMark 12L Shaking Water Bath

We have Water Baths, and we have Laboratory Shakers but there are actually many times in Chemistry and BioChemistry where you actually need to have both: The temperature control heating of a water bath combined with the shaking of a Lab Shake. Since it is considered a bad idea to put electrical equipment into water a solution is needed. Hence why BenchMark has developed the SB-12L Shaking Water Bath

4939

The SB-12L does double duty as a water bath as well as a laboratory shaker. It can operate at temperatures from Ambient+5°C up to 80°C. The accuracy is +/- 0.3°C and is set in 0.1°C increments. The shaker portion has an orbit of 25mm and speed range of 30-200 rpm in single increments. The unit is compact, with just 12″ x 13.5″ x 12″. The interior chamber is stainless steel and measures 5.3 x 9.4 x 5.5 in. The timer can have the Shaking Water Bath run from 1 minute up to 48 hours, or operate on a continuous operation. Like all electrical BenchMark lab equipment, the device can run on 115V or 230V, be sure to request the proper plug for your country if ordering for out of the USA.

Bottles, tubes and flasks can be inserted individually and the SB12L holds 12 50ml flasks, 8x125ml flasks, 3x250ml flasks, or 2x500ml flasks or 1 1000ml flask. Some larger flasks may not fit in the water bath. The SB-12L holds an equal or greater number of bottles or tubes. A Universal spring platform is included for holding 15ml and 50ml tubes which the SB-12L can hold 63 or 15/30 respectively.

4939a

Optional tube racks for holding 1.5/2.0ml microtubes or 0.5ml microtubes are available.

The SB-12L has a hinged, removable lid to reduce splashing, save energy and divert condensation. When removed the SB-12L can handle taller flasks and bottles.

Compact, efficient and with an excellent price, the BenchMark SB-12L is a great instrument for your lab.  Right now we are offering FREE SHIPPING within the continental US. Customers in AK, HI and PR please contact us for affordable shipping methods.
