Quotes from Students and Parents

  • “At the beginning of her senior year, my daughter was fearful and very intimidated by the subject of physics. Brad motivated her, as well as tutored her faithfully, and now she enjoys the encouragement to push herself in an area that had scared her to death in the past.”   — Walt Shepard, Jr., parent at The American School of Kinshasa
  • “You make science extremely fun with all the cool things you have us do!” — Zameena, grade 8 student at the International School of Tanganyika
  • “It was particularly appreciated that he provided helpful and extensive commentaries on assignments; these individualized comments allowed the children to refine their strengths and to address their weaknesses.” — Dr. Judith Weisinger, parent at the International School of Tanganyika
  • “I have never met a science teacher who is as dedicated to both his students and his curriculum.” — Marsha Buerger, Science Chairperson at Iroquois Middle School
  • “I really appreciate your kindness towards us.” — Hasita, grade 9 student at the International School of Tanganyika
  • I have to say that superlatives fall short in describing the personality, teaching style and impact that Mr. Kremer has had, not just on my daughter, but  perhaps, on all students who attended his class on Environmental Systems and Societies.” — Deepa Kapur, parent at the International School of Tanganyika

    Hello Mr. Kramer, I did all the worksheets you have posted on momentum but I can’t seem to find any answers anywhere. Are they posted on the website?

    Wonderful resources presented by an experienced teacher who loves his profession. Thank you so much for sharing.

    Dear Mr Kremer,
    thank you for the excellent resources you provide. As a physicist and environmental educator, however, I must ask you to correct a mistake. In the ecosystem slides for section 2.4, there is an image showing the rays of the sun spreading out so that they hit the earth at all different angles. This is grossly incorrect. The earth is so far from the sun that it intercepts only a tiny fraction of the light, and all light rays reaching the earth come in parallel lines. This fact is essential to understand the seasons, climate and night/day cycle, as well as the difference in insolation between the poles and equator.
