The LESS Mission

The mission of this business is to strategically and efficiently assist underfunded and overburdened schools by equipping teachers and students with appropriate STEM learning tools and technical support. Founded in the midst of very tough times for Los Angeles school budgets, LESS serves active teacher-learners who are limited by budget and time but not by imagination.

LESS intends the equipment loans seen in this website to be temporary solutions for such teachers. The ideal outcome in the mission of LESS is this: by having whole classes test-drive sophisticated equipment several times over the course of the school year, reflective and observant teachers will form concrete, creative ideas on the best uses of such equipment in their classes; these ideas will quickly lead to award-winning grant applications and proposals. Alternatively, these ideas will flower into comprehensively justified purchases of similar equipment in future years when school funding improves.

The Value Proposition of LESS

We help curious and innovative science teachers to realize badass science lessons that get students working on their own active learning. We do this by lending class sets of the lab equipment suitable for the teacher's target lessons, and by providing the technical advice and on-site support to make that equipment easy to use.

Expenses and Revenues

We have three recurring expenses:

  • rent for our storage and work space, $1000/month
  • mobile internet, $35/month
  • liability insurance and directors' & officers' insurance, $2000/year

We use donations to pay for the above and to purchase more lab equipment or parts. Sometimes we come up with some extra money to get extra paid work done, by Neyda or Ilse or Ding (see the team members' info on this web page).

We have four main revenue sources:

  • Private donations
  • Internet referrals
  • Fees for science education services
  • Sales of lab equipment and supplies

We collect private donations mostly via the PayPal Giving Fund (here is a link). We collect fees from Amazon when we refer people to amazon.com using our referral link (here it is). Some schools are able to pay us for lab equipment lending and technical support, so we are glad to earn money that way. Finally, some items are better bought than borrowed, such as eclipse viewing glasses, so we make money on sales in those cases; here is a link to our sales website.

Teachers' Comments About LESS

February 8, 2014

Hi Glen, Thank you for all of the supplies for the hydrated compound lab. Overall, it went pretty well! It took one period for them to really get the procedure down and then the next day I had them come in and go through the lab again, fine tuning their procedures and most of the got pretty accurate results. Yet another lab that we wouldn't have been able to do without the help of LESS! ...Thank you for all that you do. I truly appreciate it and so do my students!

I wanted to thank you once again for sharing the liquid nitrogen with us at Animo Venice. It really is a highlight for the kids and creates a lasting memory. Thank you for thinking of us (again!) and please keep us in mind as further opportunities arise!

Yes, grades should ultimately reflect students' understanding of science concepts and the units I have done with your equipment have enhanced and given students a more in depth understanding of science concepts. Not only that, but I would not be able to adequately deliver the curriculum to my students without the use of LESS equipment. Students learn a lot by seeing and doing and that would not have been possible without your equipment. They are formulating their own ideas and conclusions while they are using your equipment, they are motivated. Some of the same students that sit there a lot of the time with blank stares and that don't turn in work, were the ones coming to me today giving me reasons as to why they got a certain result during lab and asking if they could repeat the experiment.What you have done for my class this year has been so valuable to myself as a teacher and for my students and our school.

Thank you for offering our class the liquid nitrogen this month. It was a wonderful surprise for the students in 3rd period to see first-hand the effects of temperature on the volume of a gas. Much better than the video! Test scores for the unit were strong and I attribute that demonstration to part of the success. Thank you again, and please keep me in mind if other opportunities such as this arise.
