Resources to mark the 100th day of school with math activities. Challenge students to generate 100 different ways to represent the number 100. Students will easily generate 99 + 1 and 50 + 50, but encourage them to think out of the box. Challenge them to include examples from all of the NCTM Standards strands: number sense, numerical operations, geometry, measurement, algebra, patterns, data analysis, probability, discrete math, Create a class list to record the best entries. Some teachers write 100 in big bubble numeral style and then record the entries inside the numerals.

Acidic Oceans Prompt Evolution
Conditions of Use:

Rating

It's no secret that greenhouse gases warm the planet and that this has dire consequences for the environment whole islands swallowed up by rising seas, animal and plant species stressed by higher temperatures, and upsets in ecological interactions as populations move to cooler areas. However, carbon dioxide has another, less familiar environmental repercussion: making the Earth's oceans more acidic. Higher levels of carbon dioxide in the atmosphere mean that more carbon dioxide dissolves in the ocean. This dissolved carbon dioxide forms carbonic acid the same substance that helps give carbonated beverages their acidic kick. While this process isn't going to make the ocean fizzy anytime soon, it is introducing its own set of challenges for marine organisms like plankton and coral.

During World War Two, a fierce battle between American and Japanese forces on Kwajalein atoll left a trail of debris on the deep lagoon floor. This lagoon now has one of the largest collections of well-preserved aircraft in the world. In this video, as part of the first ever film crew allowed onto this secret military base, Jonathan explores a B-25, F4-U Corsair and Dauntless dive bomber still sitting on the bottom of the ocean, as if ready to take off. Please see the accompanying study guide for educational objectives and discussion points.

Another Perspective on Cancer: Evolution Within
Conditions of Use:

This month, pink products — from sneakers to vacuum cleaners — will pop up on store shelves. Even Campbell's Soup will shed its tomato red label in favor of pearly pink. Whatever your opinion on the pink campaign to raise awareness of and research dollars for breast cancer, the cause is unlikely to escape your notice during October, National Breast Cancer Awareness Month. Since nearly 200,000 women in the United States will be diagnosed with breast cancer this year alone, funding for research has the potential to improve the quality of life and survival odds for many millions of people. But despite increased attention and funding, the cure for this and other cancers has remained notoriously elusive. Viewing cancer through the lens of evolution helps explain why a cure seems to remain just out of reach and points the way toward new treatments.

Antibiotic Resistant Bacteria At the Meat Counter
Conditions of Use:

The pork chops you buy in the supermarket neatly packaged in plastic and styrofoam may look completely sterile, but are, in fact, likely to be contaminated with disease-causing bacteria - and not with just any old bugs, but with hard-to-treat, antibiotic resistant strains. In a recently published study, researchers with the National Antimicrobial Resistance Monitoring System bought meat from a wide sampling of chain grocery stores across the country and analyzed the bacteria on the meat. Resistant microbes were found in 81% of ground turkey samples, 69% of pork chops, 55% of ground beef samples, and 39% of chicken parts.

The next time you are in the kitchen, try this experiment: pick up a box of butter (four sticks) in one hand and a box of saltines (four packets) in the other. Which is heavier? If you said the butter, you are not alone. Most people would identify the box of butter as the heavier object even though, if you look at the labels, you'll see that they both weigh exactly one pound! This is an example of the size-weight illusion, and it is incredibly common. Read more to see the evolution (and baseball) connection ...
