Here’s a way to help
your students improve their literacy and learn about
current events in science. Every week I have my students
select a science-related article from a newspaper,
magazine, or online source. Each student attaches a hard
copy of the article to a piece of construction paper and
does the following: |
 |
1. Identifies the article’s main idea
2. Identifies and defines 5 new vocabulary words
3. Writes a 1- to 1½-page article summary
4. Writes a paragraph or 2 stating his or her opinion of
the article’s contents
To make sure my students understand the assignment, I
walk them through it the first time. I select an
article, print it on a transparency, and read it aloud.
Then I demonstrate each of the steps above, so that
students know exactly what to do. Finally, I give them a
set of printed instructions along with an example of a
completed article.

Indian corn (Zea mays) has
long been a favorite model organism for genetics
studies. Kernels are typically red, white, purple, and
yellow. However, kernels are occasionally speckled with
another color. This is caused by transposable elements (TEs),
also known as jumping genes. Click the link below to
find out more about jumping genes and why your ear of
corn just might contain some speckled kernels.
