The arrival of spring can mean spring fever for both teachers and students. Teachers have the tough job of keeping students interested and engaged in the midst of spring break, standardized testing, and the countdown to the end of the school year. Even as the year is winding down, teachers have plenty of opportunities to bring valuable learning to their students in unexpected ways. This week’s theme on the Gateway is the human body, a topic that can be adapted to many different subjects and grade levels. A study of the human body can include different types of activities including active games, art, writing, and scientific investigations.

One of my favorite guilty pleasures as a kid was to curl up on the couch with a bowl of popcorn and watch cheesy old movies on TV – the cheesier the better. Anything by Ed Wood was good, as well as the early Godzilla movies. My all-time favorite, though, was Gorgo, a monster who emerged from the sea to wreak havoc on anything in its path. The thought of something utterly unknown and foreign under the sea was an irresistible thought as a kid, and something that continues to fascinate me today.

A few places come to mind when I think about uncharted frontiers: deep space, deep sea, and deep inside the tropical rainforest. (Deep, I know!) In a perfect world, our students would have the opportunity to explore these depths on extended field trips where they would get the opportunity make their own discoveries: authentic learning at its best. Since traveling to any of these environments with a class of 30 kids (or more) is nearly impossible, you will have to get creative to use the topics in your classroom. Fortunately, today’s technology can help you bring your students close to these uncharted frontiers without setting a foot outside the classroom.

The plants around us provide a perfect hands-on biologyclassroom for students of all ages.  Fromplanting that first bean in a paper cup to conducting more involved andcomplicated high-school biology experiments, studying plants can be aneffective, concrete, fun, and low-cost way for students to explore the livingworld. 

Autumn doesn’t officially start until next week, but thesigns that the season is imminent are all around us. The nights have becomenoticeably cooler, and the days shorter. Trees are beginning to change color,and will soon begin shedding their leaves. For many plants, the lifespan of their hardworking leaves has come to anend; they will soon color, shrivel, and finally die. In some parts of thecountry, many plants will remain dormant for the winter, and only graduallyre-animate in the spring, when they unfurl new leaves.

In the 1920s, French fashion designer Coco Chanel inadvertently started a trend when she was photographed with a suntan. Previously dismissed as the badge of farmers and laborers, suntans suddenly became the emblem of luxury and leisure, and everyone wanted one. Nearly a century later, tanning is still popular. Despite all the research linking sun overexposure to skin cancer, the tanning industry continues to grow, and grosses about $5 billion annually. What’s wrong with this picture?

The study of genetics and heredity has been a part of science curriculum for quite a while now. Biology teachers can use the experiments and discoveries of Gregor Mendel along with Darwin’s explanation of natural selection to teach students the inner workings of genetics and heredity. Although I find the subject fascinating, students may tire of doing endless homozygous and heterozygous crosses on worksheets. Some of these worksheets and “boring” lessons can be replaced by some of the unique activities featured in Joann’s Picks and on our Facebook and Twitter pages this week.

One of the favorite pastimes of my parents and in-laws is to scrutinize my children and remark how each child resembles their respective sides of the family. My parents feel strongly that their grandchildren take after “our side” of the family in looks and temperament, while my in-laws feel equally firm that the children are much more like my husband and “their side”. I’m sure this same scenario is played out ad naseum in families worldwide; one wonders what happens in families with less-than attractive children.

It’s been nearly 14 years since the publication of the first Harry Potter book. The first generation of Potter fans has now likely completed college, having grown up alongside the books’ protagonists that they’ve grown to love. Although sales of the Harry Potter series have slowed since the publication of the final book, Harry Potter and the Deathly Hallows, in 2007, a new crop of readers continue to discover the series each year. According to Scholastic, the American publisher of the Harry Potter series, there are currently 143 million copies of Potter books in print in the U.S., and 400 million copies worldwide.
