Mathematics and science seem like natural partners when designing interdisciplinary lessons or units. This issue of Science Scope has some suggestions for making these lessons authentic and purposeful, integrating science with geometry, scaling, graphing, and other mathematical concepts.
Along with this issue, you can review the October issue of Science and Children for more articles on this topic that have ideas that are appropriate or adaptable for middle school students. The blog posting for that issue describes an outstanding graphing website that is suitable for all ages.
For even more ideas for integrating mathematics and science, log into SciLinks and enter the code “SC120701” for a list of websites. I saw a few that looked particularly interesting:
The “Issues In-Depth” article – Making Some Bones About It – is an excellent review of the skeletal system. Even though I’ve taught units on the skeletal system, it was an enjoyable read, and it’s important to keep our own content knowledge up-to-date. As a follow-up, go to the SciLinks site and enter “bones” or “muscles” as keywords to get lists of websites with more background information and classroom activities. You can also check out this month’s edition of The Science Teacher for an article that describes a classroom activity “Modeling Muscles.” This could easily be adapted for middle school students!

This month’s Science Teacher is a collection of ideas from low-tech card sorts (a wonderful way to get students thinking) to high-tech investigations that take advantage of technology.
The article “Fun with Ionic Compounds” was an enjoyable walk down memory lane. Many years ago, my colleague and I made cards such as these to help students visualize the concept of ionic bonding, and we found that it really helped the students. Sometimes we brought out the cards as a review, too. However, I like how these authors designed and used a review sheet to help students organize and summarize the activity. If I could only go back in time to do this again, I would use their ideas! For more information and activities on the topic of ionic bonding, log into SciLinks and enter “ionic” in the keyword search box to get lists of related websites.
Don’t forget to look at this months Science Scope, especially if you’re going to try the activity in the Modeling Muscles article to integrate a study of the skeletal and muscular systems. SS has a background article on the skeletal system that is probably designed for teachers, but high school students should be able to use the article, too. If you log into SciLinks and enter bones or muscles as keywords, you’ll get lists of related online resources. There is also an interesting activity “Making and Measuring a Model of a Salt Marsh.” This involves more than just making a model; the students’ models are used as a basis for making and graphing observations. If a salt marsh is not part of your students’ experiences, you could modify this to represent the plants and animals of freshwater wetlands.
I was observing some classes last year, and I noticed that some of the teachers referred to any hands-on activity as an “experiment,” even those activities that focused on making models, demonstrating a concept, or replicating investigations from textbooks or other resources. All of these can be valuable ways to help students learn. But I think we need to be careful with our vocabulary. You may want to check out the article “More Than One Way to Investigate” from this month’s Science and Children , which illustrates the differences between experimental and descriptive studies and how both are authentic ways to study science.
“My students are too busy to think!” When I heard a fellow teacher say this at a workshop, I hoped that she was exaggerating what was happening in her classroom. I envisioned a whirlwind in which the students followed directions for lots of activities with little time to summarize, reflect, or discuss what they were doing. I’ve been in classrooms where students were making models (DNA, atoms, the cell), but some of them really didn’t “get it” in terms of what the models meant or in applying what they were doing to other situations. Whether the students are making a model, doing an investigation from a textbook, or doing a true experiment, teachers need to help many of them to make connections between the hands-on activity and the students’ own experiences, previous activities or topics from class, or to later experiences. A few minutes of helping students to make some meaning of what they are doing can change being “busy” to being truly “engaged” with these activities.

It will soon be the time when many schools go into Science Fair mode, with reactions from students (and perhaps some teachers) that range from cheers of excitement to groans of despair. This month’s Science and Children should be required reading for any teacher whose students are going to be involved in science fairs. I also would encourage secondary teachers to review these articles, especially if your students are novices at science fairs or if you’re looking for some fresh ideas.
The S&C editor notes that when she Googled “science fair” there were more than 2 million entries! Fortunately for SciLinks users, if you enter “science fair” in the keyword search you’ll get a manageable list of 21 sites to get you and your students started!
Getting started was the hardest part for my students. The Science Buddies website has a “topic selection wizard” that guides students through the process of selecting and fine-tuning a topic. This site has sections that can help students with planning a project and teachers with planning a science fair (including rubrics for evaluating projects). If you only have time for one site (and not 2 million), this should be it!
The authors of the S&C article Four Tools for Science Fair Success also recommend Science Buddies, and the article has timelines, rubrics, and suggestions for helping students who may not have resources at home. Other articles in this issue discuss topics such as involving kindergarten students and conducting online science fairs or science expos.
There’s been a lot of talk recently that a lockstep “Scientific Method” is not always how real scientists conduct investigations, as the author of the Science 101 article describes. The article More Than One Way to Investigate illustrates the differences between experimental and descriptive studies and how both are authentic ways to study science.
For students who do a experiment for their projects, the authors of the archived Science Scope article Non-Traditional Characteristics of a Successful Science Fair Project describe six characteristics of high quality projects, and they include a rubric for assessing a student’s presentation.
You may also want to check out the resources that are part of the website of the National History Day competition. Although the topics are different, the resources include a questionnaire to help students decide whether to do an individual or a group project. This competition has several categories that reflect the authentic work of historians: documentary, exhibit, paper, performance. Each category has its own rubric. These resources could be modified for your science fair. If you’ve ever been to a NHD showcase, you won’t find any pretzel-stick log cabins! These students are doing history, just as your students will do science. (I hope your school does not require students to do both history and science projects at the same time!)
If you’ve never been involved in a science fair before, the Georgia Department of Education website has resources to help you plan and organize a science fair, from student worksheets, letters to parents, a template for a program booklet, timelines, and examples of rubrics.
With these articles and the related SciLinks websites, you and your students should be ready to go!

One of my favorite benefits of being an NSTA member is being able to view all of the journals electronically, even though I must confess that I do like the feel of holding an actual book or magazine. I subscribe to the hard copies of The Science Teacher and Science Scope, being a veteran secondary teacher. I toss the latest issues into a briefcase to read articles in between meetings, on the train, or in the car (NOT while I’m driving, of course!). But I also enjoy and get a lot out of reading Science and Children online for ideas and insights. And I have used/modified some of these ideas with my secondary students.
Sometimes I wonder about the artificial boundaries we create as teachers: elementary vs. secondary, K-12 vs. higher education, middle school vs. high school. Having been an educator at all of these levels, I’ve found that we have more similarities than differences. I hope that NSTA members take a few minutes to browse the table of contents for the journals that are beyond their own teaching assignments. I know that we’re all stressed for time, but you can skim the table of contents to identify a few articles of interest to download and read later. On the NSTA home page, use the links in the “Choose Your Classroom” list to get to the current issues of NSTA journals for elementary, middle school, high school, and college.
College? I suspect that many K-12 teachers don’t look at the Journal of College Science Teaching, but this is another excellent resource. It’s interesting that some of the articles in this higher education publication are about topics and issues with which all of us in K-12 can identify. For example, in the November issue, there are articles about team dynamics in cooperative learning, the use of learning contracts, and a case study on using “clicker” response systems in class. Even though the students described in these articles are older and bigger, there are a lot of commonalities with science education at all levels. Best of all, unlike some higher education publications, the articles in JCST are very readable, not written in “journalese.”
You can download journal articles directly to your desktop. Or you can take advantage of NSTA’s Learning Center to save the articles in your own online library of articles and other resources. Do you have a “library” yet? Mine is getting longer each month!
