Critical Thinking Activities In Science

Language skill - and more, language love and internalization - must begin early. First, of course, in the home. If it is well used there, those most crucial first usages and practices of a person's native language are formed on the right track.

Then in the lower grades of school, if a really good teacher promotes the techniques and particulars of the language in a way which implants that love of it and RESPECT for it, all the following lessons and practice of it will flow smoothly.

I had such parents and older siblings and such teachers, for which I'm ever grateful. I also had exposure to the opposite conditions, in which my first husband grew up among poorly educated people and even teachers who were proud of their bad language skills. I had to protect my own children to get them onto the right track, and there were still remnants of the bad examples!

Of course language is and should be a dynamic, fluid thing, but the purpose it fills is to communicate accurately, which requires that the sender and the receiver have the same understanding of the meaning of words and the organization of sentences and so forth. For that to be possible, there must be a standard of all those factors, i.e.: vocabulary, spelling, grammar & composition, all of which form & change shades of meaning as they are being used. That is why respect for language involves understanding of and consistency in their use.

Well - I'm surely preaching to the choir here! You're the real expert, but I wanted to confirm that I agree with your premises wholeheartedly. And, by the way, my first husband became a science teacher and it is true that being able to communicate it well is the difference between being in an ivory tower studying it and being able to share it well with others! He barely got into college, his language skills were so bad. He had to take remedial reading and English composition, in fact. He overcame some of his early training, but it required a lot of help.

Rock or Feather?
A Critical-Thinking Activity

A simple activity can reveal much about the students you work with each day. Students make and defend their choices in this activity, called Rock or Feather? Included: Comments from teachers who've used the activity -- and a printable activity sheet!

Are you more like a rock or a feather? summer or winter? the city or the country? Which word in each of those word pairs best describes you, your personality, your dreams?

That's the idea behind a very simple activity that teacher Dick Fuller calls Rock or Feather? Last fall, Fuller shared the activity with members of an online listserv for middle-school teachers. Many teachers tried the idea and continue to use it.

Fuller, an exploratory teacher at Renfroe Middle School in Decatur, Georgia, first used the Rock or Feather? activity when he was an Outward Bound teacher. The idea behind the activity is simple, he says. Students make choices. For example, are they rocks or feathers? They have to choose one -- the one that describes them the best -- and they have to be able to explain why they made the choice.

Students might consider the following pairs:

  • drama or comedy
  • rock band or string quartet
  • clothesline or kite string
  • Big Mac or sirloin steak
  • river or pond
  • bat or ball

"Of course, a lot of kids want to be able to pick something in the middle," added Fuller. That isn't allowed, however.

Some teachers might use the activity as a simple either-or checklist; kids use a pencil to mark their choices and a follow-up discussion ensues. Fuller puts a little more action into the activity. "Just to make it interesting and physical," he said, "instead of using it as a work sheet exercise, I make all the kids stand in the middle of the room. Then, for each pair of words, they have to move to one side of the room or the other. This makes it a little tougher for them because their actions are right out there and they can't hide."

Teacher Janice Robertson likes the Rock or Feather? activity so much that she uses it as an icebreaker when school opens. "The activity quickly let me know which kids have higher-level reasoning [skills], which kids are shy about speaking out loud, and which kids are followers," said Robertson, a seventh-grade teacher at Tecumseh Public School in Mississauga, Ontario.

Like Fuller, Robertson lets her students move around the room when she uses the Rock or Feather? activity. "The students really appreciate being able to move around, and they watch in amazement as some of their peers choose and justify their -- to them -- bizarre selections," she told Education World.

The variations on the Rock or Feather? activity are endless. Some teachers use it as a simple checklist. Others give the assignment for homework and ask students to write the reasons for their choices. Some use the individual word pairs as prompts for journal writing. Others invite students to think up word pairs to add to the activity.

All agree that it's a great opportunity to challenge students to think critically, make choices, and learn about themselves and others.

"I use the activity as a time filler in my eighth-grade health classes," said Anitha Diol, a health teacher at Dowagiac (Michigan) Middle School. "The students always laugh when I tell them their options. The students seem to like it, and I enjoy learning more about them."

Some teachers use another variation on the activity -- one that uses four corners of the room rather than two sides. One teacher posted to Middle-L some examples of four-choices questions:

  • Are you a 911 Porsche, a Cadillac Seville, a Toyota Camry, or a Ford Windstar?
  • Are you a mansion, a farmhouse, an apartment, or a semi-detached?
  • Are you an elephant, a gazelle, a Siamese cat, or a falcon?

"I have to confess I did use the four-corner ones because I like forcing adolescents to make decisions," added Robertson. "I also wrote the words on construction paper and had them arranged in piles -- one pile in each corner. When we were ready to go to the next group of choices, one student in each corner lifted the top card. I really believe that, whenever possible, being able to see the words as well as hear them helps students think."

Dick Fuller has tried yet another twist with eye-opening results. He has the advantage of teaching seventh graders in a single-sex setting. Last year, he did the activity with his all-boy and all-girl classes. This year he did it with the same kids, who are now in mixed-gender eighth-grade classes.

"In the seventh grade, girls and boys could be either a rock or a feather," recalled Fuller. "They could justify their answers and there was no competition between the sexes to get in the way. In that all-male setting, there was mutual acceptance of all the answers. [The same was true in the all-girl classes.] With the same group, now in a mixed class in the eighth grade, all the girls were feathers and all the boys were rocks! From that, we had a springboard into a good talk about stereotypes.

"Boys not only will talk, they want to talk," added Fuller, who has observed that in his all-boy classes. "I believe, however, they are not given much opportunity and they are forced to suffer from lack of expression because 'real men' don't express their feelings.... Separated, without the competition of girls in the class, they will talk about the double standards they face, how they pick role models, their fears and successes, and the pain of death and divorce. They just need to be given the chance."
