I’d like to share a few more comments from people who took the time to talk to me either after a session, in the exhibit hall, or on the bus. Thank you all for sharing your views on the benefits of attending the conference.

	This is my first time coming to one of the NSTA conferences. I just wanted to get updated information. I was very interested in climate change. [It’s] one of the topics they (students) like to talk about…something to help motivate me to talk to my kids about when I get back to school. Brandy Welch, Lafayette, LA
I think as far as what I’d like people to take out of it is an opportunity to think about their own instructional practice and make small steps, set some target goals, and try to improve their instruction on piece, one increment at a time. As a presenter I hope to grow as much as everyone. I’m always looking to network more; I always enjoy the conversations with teachers around the nation. It’s fun to see the experiences and backgrounds as people come in. It helps me in professional development. Jeff Marshall, presenter, Clemson University
	I am excited about the NSTA. I’m glad it was here in New Orleans. It’s such a warm place. The reason why I come is really for professional development training. I want to get all I can to be able to take back and put it to work in my classroom. Brenda Ware, Bossier City, LA (left) The conference has been great, the exhibitor workshops. I came expecting to come out with a little bit more knowledge about what it is that we do as teachers. Also, I’ve learned more, easier ways to go into the classroom so the kids can actually get what it is that we’re teaching; more effective ways and other tools that we’ve learned from each exhibitor here has been wonderful. It’s been great. And I like the free stuff. Qualesia Coleman, Shreveport, LA (right)
NSTA’s are absolutely the best conferences to come to for getting the latest information, the latest ideas, the latest technology. A lot of time is spent right here in this room [the exhibit hall] rather than at the sessions, but I also had a special project this year because I’ve been asked to build a curriculum for the country of Cambodia. I’m here collecting ideas, getting commitments from a number of the companies and specialists to help me in that project. Wayne Johnson, CA
	I’m here because I went to Atlanta about eight years ago and it was the most fabulous thing I’ve ever been to and I’ve been dying to go again. When it came so close, I couldn’t wait to get over here. Jean Marie Bernard, Lafayette, LA (right) I’m here to see just what’s out there and see what options we have for our program.

Looking for ideas to ring in Spring? Check out the S&C article Breaking the Sound Barrier by Tom Brown and Kim Boehringer for ideas on exploring sound and making simple instruments with everyday materials (e.g., rubber band guitars and string phones). You’ll be primed to add to the band—and fun—when you read the next Early Years column, “Hear That?” coming soon in the April/May issue.

Cockroaches, fast food, roadkill, rainfall—the articles in this issue of Science Scope show that middle level science students and teachers can use inquiry skills in studying almost any topic. Collecting, organizing, and analyzing data are important components of inquiry activities and these articles have great teacher-tested examples of how students can organize their observations and findings.

The article Chow Down describes studying the diets of Madagascar hissing cockroaches. I’ve been in classrooms that had these interesting insects, but most students didn’t go beyond the “Ewww” or “Oh Wow” observations. This article has some great ideas and resources for ongoing inquiry activities. These can be supplemented through the SciLinks topic Insects. I especially like Bugs from Museum Victoria in Australia. (I used to get concerned about the use of the word “bugs” until I worked on a project with a research entomologist who used the term all of the time!)

To supplement Big Macs and Healthy Teens? check out Calorie Count (if you don’t mind a few ads). This searchable site has nutritional information on individual food items as well as on menu items from fast food and chain restaurants.

OK, so your state does not have the roadkill records that the students in Roadkill Data Analysis could access. You could replicate this type of investigation with other data sources such as eBird. SciLinks can provide additional data resources, with websites on a variety of topics such as Collecting Weather Data and Presenting Scientific Data. One of my favorite online tools is Create a Graph from the National Center for Education Statistics.

Let’s not forget that we collect data in order to answer questions. The article A Land-Use-Planning Simulation Using Google Earth shows how students investigate questions with state-of-the-art data, and the simulation could be customized for anywhere. Record Keeping in Science was the theme of the January 2009 issue of Science Scope. Some of the ideas in this journal may also be appropriate or adaptable for older students.

I’m looking for ideas on how children can move water in different ways outdoors when the weather warms up. Ideally we’d have a shallow, slow-moving stream of pristine water nearby….
Indoor water exploration, in small amounts in containers, develops problem-solving skills in children. They think it is wonderful to move water from one container to another. They eagerly took up this challenge and stayed focused on the task for 45 minutes. The objective was to explore the idea of “work” as expending energy to move water, to raise the question of what force(s) move water, and to give the children a few problems to solve. Each child had two containers and the task was to move water from one to the other. I demonstrated using a spoon to move the water and then moved around the table adding a drop of food coloring to the water in each container to make it easier to see. (The food color slowly diffuses into water unless the children mix it—another cool thing to observe and wonder about.)
Some interesting problem solving was seen during this activity. Children who have the tall quart carryout containers complained that the spoon could not hold much water, that the task was taking too long. The containers are too narrow to hold the spoon completely level so only a few drops stay in the spoon. Many children decided to solve the problem by picking up the containers and pouring the water into the second container. Most did this without asking permission or looking at the teacher, but several of the children who frequently need to be redirected from disruptive behavior looked up at the teachers as they did this, a look I interpret as meaning they thought they might be doing something wrong. Another child at the table felt the need to alert me to their neighbor’s pouring behavior, expecting me to correct it! I assured all that it was okay to pour the water, and even a good problem solving idea. At first the children approached the task seriously and sedately. As they switched seats to try different container sets conversation developed with the teachers’ prompts of “How is this container set different from the first set you used?”

While the children are engaged in the work of moving water I make comments about how scientists do work and sometimes have to change their equipment to make the work easier. During the hour I offer to trade tools with the children, showing first some laundry and baby formula scoops, and later, eye droppers and pipettes, baby nasal aspirators, syringe/irrigators, and pumps from liquid soap containers (supported with a surrounding clear plastic tube). The conversation expands along with the variety of tools.
As the children work, the teachers ask how they get the water to move, what tool is working “best,” and what is “pulling” the water down into the container from the spoon. The children demonstrate how they lift the water, or push and pull, or squeeze and release, the tools. Teachers introduce the word “force” and ask, “Which tool requires the most force to use? Which tool do you have to use the most muscles to move?”
The large laundry scoop is often seen as the best tool by all the children at first, but those at the tall container stations discard it in favor of droppers as the water level gets near the bottom. Children with poor motor skills do not favor the pumps which need two hands to secure and operate.

The activity ended with a group recording session, marking tallies on a chart to show which tool they liked the best. A second chart was marked to show which tool the children thought moved the “most” water. Some children choose the tool that moved the largest amount of water at one time, others picked the tool that seemed to move water the fastest, and of course some just chose the empty section on the chart or the same section their friend picked.

Repeating the activity with an emphasis on measuring would help the children realize that “the most” can be quantified.
What are your ideas for water exploration—indoors and out?

For me, New Orleans will be “unforgettable, in every way,” to quote the old Nat King Cole ballad. I feel as though I left a part of my heart there. It was a privilege to be able to visit the Crescent City, and I thank NSTA for it.
I also will never forget all of the wonderful science educators I met and chatted with each day. Here are six of them who graciously shared their impressions of the conference and allowed me to photograph them.

	Being a [science] coach, I work with a lot of teachers. So from NSTA, I would say that at this conference, I’ve gotten a lot of information for myself as far as professional development with coaching and the different models that different states actually use. So I will take that back and share [it] with the other coaches. Then for teachers, [I’ve received] a lot of hands-on activities that they can use, a lot of information about how to scaffold lessons for English-language-learner students, because we have a big population of those students that we are now learning that we need to service much better. Charity Lawson, Landover, Maryland
I have been very impressed with the sessions this time. I’ve had a lot of trouble singling out one session for each time slot: I have to narrow it down from about 20. Mary Lara, Flagstaff, Arizona
	This is my first NSTA conference. I’ve heard about them quite a bit; wasn’t quite sure what to expect. It’s been a great experience so far. I attended a lot of workshops based on technology and sort of in that realm, and I learned quite a bit from those…a lot of different project ideas to take back to my classroom…Getting a chance to really learn how to set up a web page and how to have students interact within a web page was wonderful. Jonathan Ryberg, Astoria, New York
As a person new in a district-wide position, coordinating science education [while] out of the classroom, I approached this conference a little differently than previous ones I’ve come to. I’ve tried to focus on sessions that were more general rather than subject-specific, and so I have been looking for pedagogy and practices and things that make sense in the classroom—best practices in the classroom—and I found a lot of that. Gary Fortenberry, Lubbock, Texas
	As a [graduate] student, the opportunity to be able to go at a greatly reduced rate was really what spurred me on to be able to go, because otherwise I probably couldn’t have afforded it. Robin Reiner, Billerica, Massachusetts
I bought some really cool stuff. Lots to see. I drooled over a couple things I’m going to order when I get home, I think. And I got a bunch of things for writing grants and things like that…I teach biotechnology, and there’s tons related to what I teach—that’s even better than what I expected. Claire Salier-Hellendag, Spring, Texas

Mark your calendars for March 18–21, 2010. We’ll have to transition from po’ boys to cheesesteaks, from beignets to soft pretzels, from Bourbon Street to South Street, and from Jackson Square to Independence Hall.
See you there!
