The snow was lovely for me, arriving on a Friday night after my children were home and enough neighbors were in town to make the shoveling more of a community gathering than a huge chore.
I did wish that school was in session so I could learn what my students would do with 20 inches of snow, an unusual amount for our region and a first for their young lives.
I would have the children measure the snow depth around the playground using a stick and record the depth by drawing the length on paper, scoop snow and build up ramps for sliding mini-sleds (bowls) down, fill a measuring cup full of snow to take inside to see how much water is in one cup of snow, and dig down in the sand pit to see how the snow affected the sand. Would children work long enough to mound snow high enough (on the otherwise flat playground) for themselves to slide down?
Looking to northern regions I found suggestions for snow activities.
Speaking of in-print resources, reading aloud a fiction and a nonfiction book on the same day (or even same circle time if student attention allows) can help children relate new information to their own experiences. Try these books.
So I’m hoping for more snow in January, enough to explore but not enough to close school. And if the children do not come dressed for the weather, I’ll bring the snow inside. How about you? Are you living where the children always come to school with boots, mittens, and hats, or where the only snow people are those made from marshmallows?

Here in the Northeast, we had to dig our way through the recent storm, the most snow we’ve had in my neck of the woods for two years! I once hosted an exchange teacher from Australia in January (their summer break), who had never seen snow. Snowplows, snowblowers, snowshoes, and skimobiles were all new to her! She said it was very beautiful, “but we never realized that afterwards, one must shift it about.”
Even if you live in a part of the country that does not usually have to shift it about, snow can still be an interesting topic in a meteorology unit. In SciLinks, use the key word “Snowflakes” for grades 9-12. (It’s ok if you don’t teach at those levels–the sites have lots of photographs and ideas for many grade levels.) I really like the All About Snow site from the National Snow and Ice Data Center.
If the forecast includes the dreaded “wintry mix,” the precipitation section of the WW2010 site has diagrams that differentiate between rain, freezing rain, sleet, hail, and snow.
I saw a school the other day where the windows were decorated with “snowflakes” of eight sides. (I guess octagons are easier to cut out of paper?) For more realistic pictures, check out the photo galleries at Snow Crystals, created by a physics professor at CalTech. The photo at the top is from his site.
And if you have a copy of the book Snowflake Bentley in your classroom or library, check out the related resources on this photographer at the Buffalo Museum of Science.
My snowshoes and binoculars are ready for some winter birding over the holiday break. Best wishes to all!

Wondering if teaching about magnetism is appropriate for preschoolers, which chemistry activities can be safe for young children, what materials to provide for exploration of gravity, or how to raise butterflies?
This is a place to ask a question for other early childhood teachers to try to help answer. And for you to answer any questions posted by clicking on “Comment” below and adding your two cents, or more.
Thank you for doing science with young children,
Peggy

I’m a new middle school teacher, and last week I had to miss two days due to illness. When I came back, my classroom was in shambles and it appeared that the students did not do any work. What can I do, short of never missing another day, to make sure this doesn’t happen again?

Substitute teachers are amazing. They get a call the night before or early in the morning to take over classes for subjects in which they might not have experience or credentials. They may be unfamiliar with school procedures or a teacher’s routine. Students may have the notion unacceptable behavior is okay when the regular teacher is out . Sometimes, substitutes find no lesson plans or other materials to help them. And for this, they get a per diem that, after taxes and other deductions, can be quite modest.
“Subs” have a variety of teaching experience: some are new teachers waiting for a full-time position, others are retired teachers who want to teach occasionally or teachers in between positions trying to maintain their skills. If you know in advance when you’ll be out and who your sub will be, you can prepare class activities appropriate for his/her knowledge and skills. But sometimes, as in the case of illness, you don’t have the opportunity to create detailed plans. Having a “sub folder” can be a lifesaver for both you and the sub.
Whether your sub folder is kept in the school office or in your desk, be sure it is clearly marked and up-to-date. Provide a seating chart for each period with the students first and last names, the bell schedules, and emergency procedures (e.g., fire drill directions). Attach the syllabus for each course you teach as an overview of the content and expectations.
Include several days worth of activities that relate to the learning goals for your course. Videos are sometimes overused as sub plans, so be sure any video relates to your course goals and provide suggestions for what students should do or discuss before, during, and after watching it. Unless you know the sub is familiar with the technology in your classroom, or each class has a student designated as the tech assistant, avoid activities involving devices such as the interactive white board or electronic response systems.
Avoid busywork (such as word searches or copying notes or definitions) or directions to have the students “read silently” or “work on other homework” for the entire period. (This would be difficult for them, even when you’re in the classroom!) Activities you weren’t able to get to in a recent unit are good options to include. Some teachers collect magazine articles for students to summarize and share. If your students have access to laptops, they could work independently or in pairs on online activities or to search for information related to a course topic. (NSTA’s SciLinks has suggested websites and online resources, and there is an option to create lists of favorites students can access.)
I liked to use emergency sub time for students to review and use vocabulary (even the non-science subs felt comfortable with this). One of my favorite vocabulary activities is a “word splash.” Using a prepared word list or one the students generate (perhaps from a current event or a picture in the textbook), teams of students write sentences that include two or more of the words. Ask the sub to have the teams chose 2-3 of their “best” sentences to share with the whole class to debrief. In “word sorts,” give groups of students lists of words to categorize with a description of their thinking. In both of these activities, the sub can collect the students’ work or ask them to use their science notebooks.
Even if you are positive the sub is credentialed in science and is familiar with laboratory routines and safety precautions, I would not ask the sub to do a lab investigation with a potential for student injury or requiring chemicals, live specimens, flames, or heat sources.
Include a note in your folder with any routines that should be followed at the beginning and end of the day and during each period (e.g., attendance). Provide a way for the sub to leave a status report of what was accomplished during each class along with any issues, problems, success stories, or suggestions. If, after your preparations, the substitute does not follow your plans or allows students to behave in unacceptable or unsafe ways, you have the responsibility to share this information with your principal.
Good subs deserve respect as professional colleagues and can put your mind at ease when you’re away. For a frequent or long-term sub, a thank-you note or token of appreciation is a nice gesture. I asked some friends doing some post-retirement subbing for additional suggestions. Their ideas included a clean coffee mug to use, phone codes to access the office, the name of a nearby teacher who can assist with questions or problems, and directions from your room to the faculty lounge, main office, and restrooms.

Many of the concepts we teach in science relate to the concept of “scale” – things that are at the extremes of small (as in atoms, nanotechnology, or microbes), large (as in galaxies or blue whales), long (geologic time scale), short (half-life of some elements), or far (distances between planets and stars). Within the confines of a classroom and a short science class period, it can be difficult for students to think about these extremes.
Last year, I had the opportunity to visit the Rose Center for Earth and Space at the American Museum of Natural History in New York City. My colleague and I were blown away as we walked along the “Cosmic Pathway” and the “Scales of the Universe” exhibits. An alternative would be to explore the online resources suggested by the authors, including Cosmic Distance Scale from NASA, Get Quarked, Powers of 10, and Secret Worlds: The Universe Within from Florida State University’s Molecular Expressions website (one of my favorites). Supplement these with suggested websites in the SciLinks category Scale, with topics ranging from geologic time to explorations of the powers of 10.
Most middle school students are eager to participate in hands-on activities. The ones in this issue are also “minds-on.” The authors provide teaching suggestions, rubrics, and other resources for topics such as dealing with misconceptions (Visualizing the Earth and Moon Relationship Via Scaled Drawings), performing calculations (Using Powers of 10 to Help Students Develop Temporal Benchmarks), incorporating the topic into a 5E framework (Big Ideas at a Very Small Scale), and types of scales Giants Don’t Exist in the Real World).
I’ve seen middle school thoroughly engaged in activities such as (Get Quarked and Walking Out Graphs).
If you think you can’t do inquiry science because your school doesn’t have a lot of resources, check out The Great Top Challenge, which uses simple tops and the 5E framework to help students explore physics concepts. Look at Motion of a Spinning Top if you need a refresher and Spinning Top Circus if your students don’t know what a “top” is.

Making a dough for classroom play is also a time to teach vocabulary and math skills, and social skills such as cleaning up after oneself. Write the recipe on a page or easel paper to refer to even if your students are not yet reading. Illustrate with drawings or take photographs to use as illustrations the next time you make the play dough. Playdough is a soft, moldable flour dough that holds its shape.
What science skills will children learn while making playdough? How can making a material for play support developing math skills and language and literacy development? Here’s a beginning list; please add to it by posting a comment.
Activity | Skills used or learned |
---|---|
Reading a recipe chart with both words and pictures | Teaches that print has a purpose. Is a time to use language. Teaches that symbols represent real things, such as the color blue is a symbol for water, and two pictures of a measuring spoon represents using two spoons of an ingredient. Teaches units of measurement. |
Handling and talking about the properties of the materials (dry, wet, liquid, powdery, oily) | Teaches vocabulary. Experience with materials. |
Following the steps of a procedure | Scientists follow procedures for safety, and to reproduce the results of a first try. The order in which materials are mixed may affect the product. Measuring exactly takes practice. Children can practice self control. |
Mixing materials together | Mixing materials together can make a change—a material may get wet, clump together, or dissolve. |
Heating the playdough mixture | Heat can transform materials into a material with new properties |
Playing with the playdough | During play children use their imagination, practice social skills, develop language skills, continue to explore the properties of the new material, and express themselves artistically. |
Playdough is easy to make with children because there is some “wiggle room” in the amounts—a little more water will make a softer dough, a little less oil will make it a bit sticky. Recipes for playdoughs (a valuable classroom tool) are widely available online and in activity books. Here it is again!
Ingredients and materials:
Mixing to make a change is fun, especially when you get to play with the resulting mixture. Your class might want to take their recipe to another class and teach them how to make playdough!
