Teacher Scholarships for Lab Safety

LSI-CHAS Laboratory Safety Workshop Scholarships

 The American Chemical Society’s (ACS) Division of Chemical Health and Safety (DCHAS) offers workshop programs twice a year at ACS National Meetings. The Laboratory Safety Institute (LSI) has conducted a one-day Laboratory Safety Workshop as part of this programming for the past 27 years. The LSI workshop is always held on the Friday before the start of the National Meeting.

The 2015 schedule is March 20th in Denver, and August 14th in Boston. DCHAS has reduced the 2015 Full Non-DCHAS Member registration fee ($425) for full-time school science teachers who are American Association of Chemistry Teachers (AACT) members by over 75% to $99.

Thanks to a donation by Dr. and Mrs. James Kaufman in celebration of the 25th anniversary of these workshops, scholarship assistance of up to $99 is available to cover the workshop registration fee for all K-12 science teachers with demonstrated need.

Registration for the Workshop can be completed online on the conferences page of the DCHAS website.

  4. Using your mixer (I have a kitchenaid) beat the butter for 3 minutes until light and fluffy and then gradually add the sugar while beating. Scrape down the sides with a spatula and get everything incorporated.   Now add the vanilla and beat until smooth.
  5. Beat in the eggs, one at a time, beating 30 seconds after each addition and then stopping and scraping down the sides.
  6. Now add the flour mixture alternately with the liquid mixture to the butter mixture, gently stirring until all incorporated ending with a dry mixture addition.
  7. Pour into the muffin liners and bake at 350 F about 20-22 minutes until they spring back when touched. Cool and frost with your favorite frosting. I use a cream cheese/butter frosting.
