It’s interesting in this issue to see how teachers can incorporate inquiry learning into topics such as Bernoulli’s Principle, bridge design, photosynthesis, a beach clean-up program, rocks, paper airplanes, maple seeds, and ponds. The authors show how you don’t need elaborate materials to create learning experiences for students that go beyond cookbook demonstrations and focus on real inquiry and problem solving. The articles describe these investigations and also have advice for teachers who want to include more inquiry in their classes. The articles have lots of real-life classroom examples, and the author share their resources, rubrics, and diagrams.
I followed up on some of the suggested websites:
Efforts to promote inquiry in science have been around for a long time (I remember the discussion in my methods courses eons ago, and it’s always at hot topic at NSTA conferences). So why are we still talking about it? What is keeping us from using more inquiry in K-12 science classes? The Science Scope article Engendering Inquiry discusses some of the perceived barriers to implementing inquiry instruction. Are there others? What do you think?

As a preschool teacher I try to be aware of how my work might introduce or reinforce misconceptions in my students’ understanding of concepts. In the Perspectives column in the September issue of Science and Children, Michele H. Lee and Deborah L. Hanuscin write about common misconceptions about astronomy, A (Mis)Understanding of Astronomical Proportions? (pg 60-61).
They report on studies that have found that elementary school age children
So I will use the word “round” to refer to wheels and plates, and “spherical” to refer to balls and oranges, make 3-D models with playdough instead of drawing diagrams, and provide materials for manipulation when children are asked to tell what they know. It sounds like fun!
Blowing bubbles is an activity where using the word “spherical” comes naturally. The bubble wand opening is a circle and the bubble is a sphere. Children can point to a ball or a flat round disk to show what shape they see when they blow a bubble.

At our inservice last month, we learned several strategies for writing in science classes. But when I tried one in my classroom, it went over like a lead balloon. What was I doing wrong?
—Rosalind, Denver, Colorado
How many times have we heard “Well, I tried <fill-in-the-blank>, but it didn’t work”? And then the classroom instruction reverts to the tried and (not necessarily) true methods. This certainly happened to me when I tried a different instructional strategy, an alternative form of assessment, or a new classroom management routine. Students would roll their eyes or complain before we even started.
I’ve come to the conclusion that any type of change is difficult for some people (not an original thought on my part). We are such creatures of habit! By the time students are in the upper elementary grades, they have a definite idea of what school is “supposed to be.” Whenever teachers or administrators deviate from this comfort zone, the defenses go up.
Students are not the only ones who have comfort zones. Just try a different format for a faculty meeting, a new schedule for inservice days, or a strategy to get teachers out of their seats at a workshop. I had a graduate student in one of my classes who was incredulous that I expected them to work cooperatively and to participate in class discussions. “I didn’t know we were going to have to, like, DO anything!” she remarked with an angry look. I had obviously encroached on her comfort zone.
I’m not sure who invented the three-time rule, but it seems true: once is an event, twice is a coincidence, but after the third time a trend or pattern is established. If we try a new strategy once and it doesn’t fit the modus operandi, the students may assume that if they fuss or refuse, we’ll say “Well, that didn’t work” and classroom life will return to the-way-things-are-supposed-to-be.
But if we know that something is the right thing to do, that a research base is behind it, or that it will ultimately pay off in better learning or a better classroom environment, we should stick with it and explain why we are doing something new or different. We may need to model the activity or strategy, too.
This actually turned into several action research projects for me. As I was implementing something new, I noted what the responses were and by whom. I reflected on whether I was implementing the new strategy appropriately and how I had introduced it. After all, my students weren’t any different from others. Why would something work in many other classrooms across the country, but not in mine?
Being aware of the three-time rule (event, coincidence, pattern) and understanding that it often takes several attempts before a new practice is accepted – whether by students or teachers – worked for me. Just give yourself some time and keep at it. If it’s the right thing to do, the students will internalize it, and soon what was once a new idea becomes part of the-way-things-are-supposed-to-be.

The big fish died. The constant silent presence of the plecostomus—now hiding in the cave, now sucking algae off the aquarium wall—is gone. Donated by a parent who has moved on to high school PTSA duties, the odd fish taught 10 years of preschoolers about its needs: warm water to live in, particular kinds of food, and a place that was quiet and still. Only then would it come out, quickly returning to the cave as children noticed it and the shout went up, “The Big Fish is out, the Big Fish is out!”
Not many children commented on the fish’s death, perhaps because school has just started and over the summer they had forgotten about the Big Fish. The tank needs an algae eater. It’s time to buy a new little “Big Fish.”
Do you have a fish tank in your classroom? How have you used it in teaching? Read more about these cool fish on The Ultimate Pleco Community page.

Who hasn’t looked into the night sky and wondered about the stars and the universe? But upper elementary and middle school may be the last chance for many students to study or be exposed to concepts in astronomy. Earth and space science is not offered in many high schools or it not chosen by college-bound students. And yet, astronomy is a science that can be pursued and enjoyed even beyond one’s school days.
The articles in this month’s Science and Children provides teachers with many ideas for getting student started on a lifelong learning adventure. Secondary teachers can get ideas for working with students who do not have much background in astronomy.
Several of the articles have SciLinks codes: SC090801 for Exploring Mars; SC090802 for Moon Phases; SC090803 for the Other Planets; and SC090804 for What Causes Day and Night. Members can explore other topics by typing “astronomy” or “universe” as a SciLinks keyword.
It’s hard to study astronomy during the school day, but fortunately there are lots of websites that can be used to get students (and teachers) interested in the topic. Here are some ones worth checking out:
If anyone has used either of these last two resources, please let us know what you think!

The S&C astronomy issue article Sky Observations by the Book (NSTA membership required) presents lessons specifically for teaching young children astronomy concepts with picture books. Authors Kathy Cabe Trundle and Mesut Sackes describe ways to prompt children to notice differences in day and night in pictures to foster understanding about objects in the sky. An important reminder is to evaluate the books first to make sure they do not introduce misconceptions, but keep in mind that flawed books provide the opportunity to help students analyze content.

A walking fieldtrip can bring much needed outdoor time and opportunity for scientific observation to a class schedule. The objective can be to view the sky, look for birds, find seeds, or to inventory the surrounding environment.
Whether just a walk around the school building or to a natural area several blocks away, a walking fieldtrip is most successful when materials for dealing with unexpected discoveries are brought along.
Here’s a short list of what might be useful:

Planting spring-flowering bulbs connects the seasons of Fall and Spring in the minds of young children as they wait all winter for the bulbs to sprout and to see the flowers blooming in the spring. Following the growth of daffodils or tulips reinforces learning about cycles in nature and noting the sequence of the seasons. Read about planting bulbs on the Clemson University Extension Service webpage.
Reading a book, handling a bulb, and seeing what is inside (no tasting!) prepare children to plant a living thing, a flower bulb. Planting a Rainbow by Lois Elhert (Harcourt, 2003), shows bulbs in the ground before sprouting and when blooming. I also like cycle-of-the-season’s books, such as, When This Box is Full by Patricia Lillie (Greenwillow Books, c1993), What Comes in Spring by Barbara Horton (Random House, c1992), Spring: An Alphabet Acrostic by Steven Schnur (Clarion Books, c1999), and Be Blest, a celebration of the seasons by Mary Beth Owens (Simon & Schuster Children’s Publishing, 1999).
Here’s a song the class can act out while waiting for a turn to plant, (based on, and to the tune of a traditional song,“Jack in the Box” or make up your own):
Spring flowering bulb, (children curl face down on floor/ground, hiding face)
So safe in the ground,
Way down inside, your little dirt mound, (hands curve over head)
Spring flowering bulb so quiet and still,
Won’t you sprout up? (heads up, stretch arms up high)
Of course I will! (jump up!)
I usually explain the word “mound”, and sometimes the word “sprout” before repeating the song.
There are seasonal bulbs that grow and bloom in regions that never experience freezing temperatures, such as the “Spider” lily (Hymenocallis sp.) Tropical Giant. Learn about other tropical bulbs in the
Amaryllidaceae or the Amaryllis family from the Pacific Bulb Society.
Planting the bulbs is a good investment because many species return, year after year, and can be appreciated in many ways. The sweet-sharp-green smell of daffodils takes me back to my childhood.

OK, it’s almost October and it’s time to celebrate science. Get ready for Earth Science Week this year (October 12-18, 2008). The theme is “No Child Left Inside.”
If you really are in a celebratory mood, you can move right into National Chemistry Week October 19-25, 2008. The theme is “Having a Ball with Chemistry.”
Both of these websites have lots of resources, and it shouldn’t be hard to find some that align with your curriculum and standards. I did not get any results when I googled National Physics Week or National Biology Week, but please let me know of any nationwide events in these areas!
Astronomy gets into the lineup of October events, too. Check out the Great World Wide Star Count in which your observation data can be uploaded and shared with participants from around the world during the October 20 – November 3 time period.
Don’t forget that October 23 is also the time to celebrate Mole Day.
And then, top off the month by attending the NSTA conference in Charlotte, NC from October 30 – November 1.
With all of these events to celebrate in October, who needs Halloween?

My principal is talking to us about using “formative” assessments. Does this mean taking time away from instruction for more tests? When will I have time to teach?
—W.S., Overland Park, KS
While teaching a lesson, it’s easy to get wrapped up in what we are doing or to “cover” material. But how do we know what students are actually learning? We can wait for the results of state tests, we can give end-of-course exams, or we can create/use unit tests or final projects. These summative assessments help us make decisions about our courses and curriculum (assuming we look at the results), but they don’t tell us much about which students are having problems or have developed misconceptions during our instruction. And by then it could be too late to go back and review or reteach.
Formative assessments are ongoing, classroom-level assessments that are critical to discovering what students are learning during the instructional process, and they help us know if we can move on (if students have learned a topic) or if we need to revisit our instruction to correct any misconceptions or to fill in any gaps. These quick and focused checkups can provide just-in-time information on what students know or can do.
The good news is you probably already use many activities that could be part of a formative assessment process. Quick, frequent thumbs-up/down responses from the students give instant feedback during a discussion. Some teachers use small whiteboards or half sheets of paper on which students write and display short responses. Challenge students to quickly write down their understanding of the topic (as a short summary, graphic organizer, or diagram) in their notebook/journal, share their writing with a partner, and then summarize to the class. These activities could be warm-ups to get your class engaged or bell-ringers to wrap up the day’s lesson.
While students are working together, you can use a checklist of skills, lab behaviors, or quick questions to do “spot checks” while walking around the room. Many schools (including colleges) have clicker systems allowing the students to respond electronically. Vary the methods so they become an integral and enjoyable part of the learning process. Of course, traditional quizzes and lab reports can be used formatively. All of these strategies assume all students are involved, that we provide feedback (more than just a grade or percentage correct), and that we use the results ourselves to improve or validate our instruction. Students should see these activities as part of the learning process, not just as a special event.
Two recent NSTA periodicals focus on assessments: the January 2008 Science Scope and the April 2008 Science and Children (NSTA members can read these online). I’d also recommend the NSTA Press book Science Formative Assessments: 75 Practical Strategies for Linking Assessment, Instruction, and Learning. I showed it to some of my colleagues in other subject areas, and they said quite a few could be adapted to their fields.
I heard once that formative assessment is the tasting a chef does in the kitchen, while summative assessment is the guests celebrating a good meal. If the chef does not do any tasting, he/she is taking a chance on whether the meal will be appetizing for the guests!
