Using Community Resources

Science Scope Cover I was in an elementary school where scientists from a nearby university visited the schools periodically to work with the students on a variety of activities and to describe their own research. The students were impressed with meeting "real" scientists and learning about their work. (One little girl asked if the scientist would autograph her notebook!) These students were learning about careers first-hand.

If there is a shortage of career role models in your community, we often have students could do "reports" on careers in science, looking at educational requirements, salary projections, etc. But I wonder how middleschoolers really relate to this activity? The Internet can bring people from around the world into our classrooms. For example, NOAA's Ocean Explorers has archives of webcasts that include videos of scientists at work.

And I just got a recommendation from the Math-Science Partnerships' Learning Network about the No Boundaries project from NASA. In this project, students explore STEM careers (science, technology, engineering, and mathematics) within the context of NASA programs. It appears to be well designed, with rubrics, graphic organizers, cooperative learning suggestions, and other guidelines. Students can submit their projects later this year in a national competition.

If you're not affiliated with a Math-Science Partnership project, you can sign up to join the Math Science Partnerships' Learning Network which has a guest newsletter that is a great source of information and suggestions.

Activities and Investigations

The Science Teacher Cover I was facilitating a workshop once, and I overhead these statements from two science teachers: My students are so busy, they don't have time to think and We have so much fun, the students don't know that they're learning.

I hope that the teachers were oversimplifying their classroom environment. I can certainly understand the teachers' desire to engage students actively and to make science enjoyable, but I think what might be missing in their classes is a chance for students to connect new learning to what they already know, to ask questions, to predict, to apply what they are studying to new situations, or just to quietly reflect on what they are doing. There is a difference between doing busywork and being cognitively engaged in a task. (When I do the laundry, I'm busy, but I'm not very engaged!) I'm also curious as to why students have the impression that learning is a chore or a dull experience rather than an enjoyable, positive one? If students don't know what and how and when they are learning, how can we ever expect them to become independent, lifelong learners?

Fortunately, this month's Science Teacher has many suggestions for engaging students in meaningful tasks and making learning a positive experience.

The article Energizing Students describes how to apply concepts from neuroscience to "maximize student engagement and attention." For our colleagues at the primary level, moving around, stretching, and varying the activities are standard procedures. High school teachers may be skeptical at first, but I've seen for myself how even a simple stretch break can help students to re-focus, and I would certainly explain to them why we're stretching--to get more oxygen to the brain. The relationship between learning and the brain is a fascinating one, and two interesting neuroscience resources are Neuroscience for Kids and The Brain from the Franklin Institute.

Another interesting concept is using the arts to get students actively engaged, whether it's creating a video (Movie Mitosis) or a cartoon ( The Art of Physics) to illustrate what the students are learning in science. Both of these include rubrics to help students focus their learning and their creativity. (See the August 2008 blog for more on rubrics.) And when the students have completed their projects, the projects can be shared with other classes, especially younger students.

The article "Life" in Movies has great suggestions for getting students to think about the science (or lack of scientific accuracy) in popular films. If you 're an elementary or middle school teacher in a school where films are shown at the end of a marking period or before a break, check out the potential discussion topics for films such as Finding Nemo and A Bug's Life. Even if students have seen the films, you can engage them from a different perspective. There are also suggestions for how to select films to show in a school setting. The author of the popular Bad Astronomy site discusses movies that are (or are not) scientifically accurate. It's a fun (and engaging) site.

Science and Winter

I was in a school once where the teachers did a "winter" unit on penguins with activities that included trade books, puzzles, writing activities, and the showing of several popular films. But there was not a lot of science involved, and one of their bulletin boards even showed a group of polar bears and penguins frolicking together (Arrgh!). They put a lot of time and effort into this, but I had to wonder what the students actually learned about these birds or about the winter season.

Any change of season can be a focus for science activities. A colleague starts each season by having students brainstorm seasonal questions and adding a few of her own. She shares some of the winter ones:

Winter scene MLB Why do we have "winter?" What is a "solstice?"
What happens when animals hibernate?
How do frogs survive the winter?
Why should we "dress in layers" when it's cold?
Is it true that no two snowflakes are alike?
What does a desert look like in winter?
Is there a difference between a conifer and an evergreen?
Are all conifers called "pines?"
Do we see different constellations in the winter? Why?
How does a thermostat work? How does a heat pump work?
Why do people put wax on skis?
What is the "jet stream" that seems to influence our weather?
Do El Ninos and La Ninas happen in the winter?
Why do icicles form? What makes ice slippery?
How does "insulation" work?
If ice is a solid, why does it float?
What is "frostbite?"
Does colder weather cause us to catch a cold?
What’s the difference between the Arctic and Antarctica?
Why do highway crews put salt on the road? What happens to the salt later?

Note how these questions include topics in the life, physical, and earth sciences. She puts them on her "seasons" bulletin board and refers to them in her lessons where appropriate. For example, during a unit on the states of matter she would address questions related to ice, a weather unit would incorporate the questions on El Nino. At the end of the season she wraps things up with any remaining questions.

She does not look up all of the answers herself to present to the students. Through hands-on activities and Internet searches, she guides students through the process of answering their own questions. That's where SciLinks can help. Use keywords such as Snowflake, El Nino, Identifying trees, Ice, Season, Heat, States of matter, or Constellations to access web-based sources of information and ideas for related activities.

States of Matter

Science and Children Cover
It’s one thing to get students to recite definitions for the states of matter. But what do they really understand? For instance, the word "gas" is confusing. My students had to stop and think whether the word was referring to a state of matter or to the liquid that is pumped into the fuel tank of a car. Likewise, when the textbook definition of "liquid" mentioned that it was a substance that could be poured and took the shape of its container, they wondered why sugar and salt weren't considered liquids.

This Science Scope issue has lessons, background information, and teaching suggestions and SciLinks has many online resources for helping young students learn about matter. Just use the keyword matter and your grade level to see several categories of websites related to matter. Here is a sample of some that are geared to elementary grades: I was once observing a class in which the 4th-grade students were making "oobleck." The teacher was well-organized, but she missed an opportunity to go beyond simply having the students make the substance and play with it. The article Concept-Focused Teaching describes how activities can help students learn and understand big ideas or concepts. The activity Oobleck from the Jefferson National Laboratory has some ideas for focusing students on the states of matter as they make (and play with) oobleck.

If you teach middle school, scan the table of contents in this issue for articles with some good teaching ideas for helping students who may not have a strong science background.
