Idaho Power sends along this video, teaching how to avoid starting your car on fire on a sunny day.

Can you use this video in your classroom?

It demonstrates science, how lenses work, how light works. Science classes should be able to use it.

The video offers safety instruction, stuff elementary kids should know to improve the safety of their daily lives. Their parents should know about it, too. Instruction for the kids, and a safety flyer for kids to take home.  A short piece Boy Scouts can use for Safety merit badge instruction. Surely Girl Scouts can use the safety instruction for a badge.

What other uses can you find?

Basic science provides critical basis for living, for parenting, and for teaching and learning. Anyone opposed to science instruction should rethink the harms that ever result from ignorance, or even forgetfulness.

Warning signs in Texas

September 7, 2014

On several Texas rivers one may rent a large tire inner tube, to float down the river on a good day.

Safety instructions sometimes are minimal, but effective.

Do you think the students have wi-fi to finish their homework on the way to school?

(This is not necessarily representative of all Indian school buses.)

One wonders at the stories behind such “buses” and their use.  It might make an interesting geography assignment, to find out how students get to school in other nations.  What is the most exotic, bizarre, dangerous or luxurious ride?

Dumb ways to die, and a catchy tune

June 25, 2013

Here’s a video I meant to post months ago — but I can’t find it now.  Martketplace had a story on it today.

The idea is, “don’t get hit by a train.”

Still from short movie PSA,

Still from short movie PSA, “Dumb Ways To Die.”

It’s a safety message from Australia.  Highest and best use of PSAs, if you ask me [most links added here].

A clever Australian public service ad campaign promoting train safety has swept a number of advertising prizes at the Cannes Lions International Festival of Creativity, the world’s biggest annual awards show for professionals in the creative communications industry.

In all, the rail safety campaign took home the most prizes ever awarded to one campaign in the festival’s history.

“We’re thrilled with the outcome of the campaign. The main reason for that is that it starts a discussion about train safety in a way that young people will associate. We’ve deliberately not been threatening or shown graphic imagery,” said Leah Waymark, general manager of corporate relations at Metro Trains, Melbourne’s private rail service.

Metro Trains helped to co-produce the three-minute video, “Dumb Ways to Die,” which was created to teach people to be careful around trains. Since its November 2012 release, the video has racked up more than 50 million YouTube views, sparked several parodies, and even spawned an iPhone game. Not bad for a safety warning advertising campaign.

See for yourself:

The vocals remind me of early Edie Brickell and the New Bohemians; I wonder if the artist has any other work out there worth listening to.

It won’t be popular for flash mobs, I predict.

Curious update, September 19, 2013:  This ad has been banned in Russia.  No kidding.

Controversy

Everyone fell head over heels in love with the campaign. Except Russia. (Naturally). The video was censored by the Russian government and viewers were informed that, “This content is not available in your country due to a legal complaint from the government.”   The Russian government convinced itself that this video promotes suicide in an attractive comic format and will entice children and teenagers to “push the red button,” “set fire to their hair” and “poke a grizzly bear with a stick.”

Wear long sleeved shirt and long pants, socks and shoes.

DUET™ Dual-action Adulticide cannot be diluted in water. Dilute this product with light mineral oil if dilution is preferred.

USE AREAS: For use in mosquito adulticiding programs involving outdoor residential and recreational areas where adult mosquitoes are present in annoying numbers, and in vegetation surrounding parks, woodlands, swamps, marshes, overgrown areas and golf courses. For best results, apply when mosquitoes are most active and meteorological conditions are conducive to keeping the spray cloud close to the ground. Application in calm air conditions is to be avoided. Apply only when ground wind speed is greater than 1 mph. Air temperature should be greater than 50 F when conducting all types of applications. Do not treat a site with more than 0.0036 pounds of sumithrin or 0.0008 pounds of prallethrin per acre in a 7-day period. More frequent applications may be made if adult mosquitoes have reinfested the treatment area and to prevent or control a threat to public and/or animal health determined by a state, tribal, or local health or vector control agency on the basis of documented evidence of disease causing agents in vector mosquitoes or the occurrence of mosquito-borne disease in animal or human populations, or if specifically approved by the state or tribe during a natural disaster recovery effort. Do not exceed 0.094 pounds of sumithrin or 0.021 pounds of prallethrin in any site in a year.

SPRAY DROPLET SIZE DETERMINATION
Ground-based Application: Spray equipment must be adjusted so that the volume median diameter (VMD) is between 8 and 30 microns (Dv 0.5 < 30 um) and that 90% of the spray is contained in droplets smaller than 50 microns (Dv 0.9 < 50 um). Directions from the equipment manufacturer or vendor, pesticide registrant or a test facility using a laser-based measurement instrument must be used to adjust equipment to produce acceptable droplet size spectra. Application equipment must be tested at least annually to confirm that pressure at the nozzle and nozzle flow rate(s) are properly calibrated.

Aerial Application: Spray equipment must be adjusted so that the volume median diameter produced is less than 60 microns (Dv 0.5 < 60 um) and that 90% of the spray is contained in droplets smaller than 115 microns (Dv 0.9 < 115 um). The effects of flight speed and, for non-rotary nozzles, nozzle angle on the droplet size spectrum must be considered. Directions from the equipment manufacturer or vendor, pesticide registrant, or a test facility using a wind tunnel and laser-based measurement instrument must be used to adjust equipment to produce acceptable droplet size spectra. Application equipment must be tested at least annually to confirm that pressure at the nozzle and nozzle flow rate(s) are properly calibrated.

GROUND ULV APPLICATION
To control Mosquitoes and other listed insects, apply DUET™ Dual-action Adulticide at a flow rate of 2.5 to 7.5 fluid ounces per minute at an average vehicle speed of 10 mph using a swath width of 300 feet for acreage calculations (see chart below). Under normal residential conditions a flow rate of 4.5 fluid ounces per minute is recommended. If a different vehicle speed is used, adjust rate accordingly. These rates are equivalent to 0.0003 to 0.0008 pounds of Prallethrin and 0.0012 to 0.0036 pounds of Sumithrin® and piperonyl butoxide per acre. Vary flow rate according to vegetation density and mosquito population. Use higher flow rate in heavy vegetation or when populations are high. For proper application, mount the applicator so the nozzle is at least 41/2 feet above ground level and directed out the back of the vehicle. Failure to follow the above directions may result in reduced effectiveness. DUET™ Dual-action Adulticide may also be diluted with a suitable solvent such as mineral oil and applied by GROUND U.L.V. equipment so long as 1.24 fluid ounces per acre of DUET™ Dual-action Adulticide is not exceeded. Refer to the tables below for flow rate calculations for diluted end-use formulations of DUET™ Dual-action Adulticide.

Use the following table to calculate application rates:

[table viewable on the .pdf document]

DUET Dual-action Adulticide may also be applied undiluted with non-thermal, portable, motorized backpack equipment adjusted to deliver ULV particles of 50 to 100 microns VMD. Use 0.41 to 1.24 fl.oz. of the undiluted spray per acre (equal to 0.0012 to 0.0036 lb. sumithrin/acre) as a 50 ft (15.2 m) swath while walking at a speed of 2 mph (3.2 kph).

DUET Dual-action Adulticide may be applied for urban ULV mosquito control. For control of resting or flying adult mosquitoes, biting flies and biting midges in areas such as utility tunnels, sewers, storm drains and catch basins, pipe chases, underground basements, underground passages, parking decks, crawl spaces or uninhabited buildings. DUET Dual-action Adulticide may be applied using mechanical foggers, hand-held or truck mounted ULV equipment, non-thermal foggers or other spray equipment suitable for this application. Apply DUET Dual-action Adulticide at rates up to but not exceeding 0.0036 pounds sumithrin per acre in a 7-day period (not to exceed 0.094 pounds sumithrin per acre in any site in any  year).

AERIAL APPLICATION
Application shall be made when ground wind speed is equal to or greater than 1 mph. Applications shall be made when surface temperature exceeds 50ºF. Application shall be made at 75 feet to 300 feet for rotary aircraft and 100 to 300 feet for fixed-wing aircraft. Flow rate and swath width shall be set so as to achieve 0.41 to 1.24 fluid ounces of DUET™ Dual-action Adulticide per acre.  Appropriate spray systems include rotary atomizers, flat fan, high pressure, and high pressure impaction nozzles characterized and oriented to achieve the droplet characteristics above.
DUET™ Dual-action Adulticide may also be diluted with a suitable solvent such as mineral oil and applied by aerial U.L.V. equipment so long as 1.24 fluid ounces per acre of DUET™ Dual-action Adulticide is not exceeded. Refer to the tables below [on .pdf] for flow rate calculations for diluted end-use formulations of DUET™ Dual-action Adulticide.

Lightning? Don’t stand under a tree . . .

October 2, 2011

Talk in class turned to Ben Franklin’s kite experiment.  “Don’t try this at home,” I said.

Do students ever listen?

Here’s an amateur video showing why standing under a tree in a lightning storm could be a bad idea.  Can students extrapolate this to flying a kite in a storm?

Surely there is better video of such events somewhere . . . can you tell us where?

Found it at Wimp.com, with a tip of the old scrub brush to Thom Holland, Scouter with the 626 units at Penasquitos Lutheran Church, San Diego, California.
