| Worm Farm |
It's time to stop thinking of earthworms as just fish bait, or as "ooky" things crawling in the dirt. Aristotle called them "the intestines of the soil." They are a vital component of the ecology of our soils and an important rung in the food chain. All species of earthworms are fascinating and worthy of our respect.
One species, the night crawler (Lumbricus terrestris), is a large worm that can measure up to 25 centimeters in length and up to 1 centimeter in diameter. Night crawlers can be found in most areas of the United States. Populations of night crawlers will vary dramatically with soil conditions. It's thought that an individual worm requires about 1,500 cubic centimeters of soil - that's equivalent to a cube of soil 12 centimeters on a side. If you laid such cubes out on a lawn, you'd have about 70 of them per square meter, so populations of night crawlers could be as high as 70 per square meter of lawn! However, published estimates tend to put their populations at a more modest 10-15 per square meter, still a lot of worms!
Judy made a plan to figure out how many night crawlers lived in her yard. She measured a 3 meter by 4 meter area of her lawn and marked it off with string. Before sunset she watered the area until it was soaked with water. That night when it was dark, she shined a flashlight on the lawn inside the string. The night crawlers were out of the ground and lying on top of the grass. Judy carefully counted them. Her count was 79 night crawlers.
How many night crawlers per square meter did Judy have in her lawn? (Please calculate to the nearest tenth.)

Bonus Question
| Repeat Judy's night crawler experiment on your lawn to determine how many night crawlers your lawn has per square meter.

Fact or Opinion
Posted: 2010-04-15
Hello All-
My name is Paul McKinney and I am very pleased to be a regular contributor to this new and informative blog site.
First let me tell you a little bit about who I am and the experiences I bring to this site. I always find it important to identify with those I share ideas, opinions and most importantly research. This is my 42nd year in the field of education. Notice that I did not identify education as a profession.Along the way I will explain my reasoning for this statement.
I started teaching in 1968 in a very small community in upstate NY.And for the next 22+ years taught in the public schools around Central New York. I must say that my favorite teaching experience was when I taught Kindergarten for 5 years. I learned more about teaching from teaching these little munchkins, than I did from taking any methodology class in undergraduate or graduate school. I taught all grade levels through 5th grade, special education through high school, and was an Assistant Director of Special Education for 5 years in charge of Curriculum and Instruction representing nine different school districts. For the past 20 years, I have been consultant trainer for SRA, a Project Director of Project Follow Through, and owner and principal in two major staff development companies. I am presently Vice President and partner in Educational Resources, Inc. (ERI) (www.erigroup.us) And I am proud to say that for 40 of those years I have been associated with all of the powerful instructional programs that come under the "umbrella" called Direct Instruction. OK, there you have it. I also need you to know as I write on this blog, I promise to always delineate between fact and my opinion or experience.
Earlier, I made the statement that Education is still a field and not a profession. I say that after the accumulation of 42 years of working hard, reading lots, studying diligently, and observing always. We are in fact a fickle profession (OPINION). My exp....

Welcome to the New MathMastery
Posted: 2010-04-15
The MathMastery team is excited about the launch of its new web site. On the site you will find a wealth of math and science content. Our blogs will be hosted Paul McKinney and his team from Education Resources Incorporated, Sky Lamont, a home schooling mom, and myself. In this first posting I want to introduce Paul and Sky and set the stage for future interactions one can expect.
Paul McKinney, Vice-President of Educational Resources, Inc. (ERI) was recently notified that he was unanimously selected by the Board of Directors of ADI to receive this year's Life Time Achievement Award. The award comes as a result of a 40-year commitment to Direct Instruction. Paul started his teaching career in 1968 in Phoenix, New York. He has spent his entire career, teaching, training, supervising and promoting effective teaching and D.I. In 1989, Paul left public education to form and become President of J/P Associates, Inc. Then again in 1999, along with his partners Dr. Molly Blakely and Ed Schaefer, formed Educational Resources, Inc. a professional staff development company. ERI presently partners with school districts across the United States and abroad. Paul holds a B.A. and an M. S in Early Childhood Education from the State University College at Oswego and a C.A.S from Syracuse University in Educational Administration. Paul will receive his award at the annual ADI conference in Eugene Oregon in late July.
MathMastery online subscribers already know Paul. He is the narrator on many of the math and science videos. Check out Changing the Sides of an Equation video in the Absolute Value and Problem Solving tutorial in the Equations, Roots and Exponents! See how many more times you can find Paul as a narrator on MathMastery. Send us your answer. The winner(s) will get three months free subscription to MyMasteryNetwork, MathMastery’s online math subscription.
I look forward to Paul’s contributions to the MathMastery blog on effective teach....

The Power of Positive Association
Posted: 2010-04-15
One
of the basic challenges a homes schooling parent faces is resistance from their
child/children towards their daily lessons. I'm sure there are a couple of
parents out there right now who know exactly what I mean -the moaning, the sad
faces, the snails crawl paces at which the kids do their activities - you know,
the pain we parents go through.
I'm
a life coach, one thing I can tell you is that sometimes my adult clients act
the same way. Take for instance a client who wants to lose weight. Making
healthy eating choices and exercise are not always easy - or are they? It
really depends on the perception they associate with having to do those
activities. If they have positive associations, then their exercise routine
flows even when they're pushing through tremendous resistance like lifting
weights. If while lifting, they co....
