Even if the weather outside isn’t frightful, you will find Insta-Snow® (SNO) delightful! As an educator I have found so many wonderful things to do with this product. And it’s something that can be adaptable for students of most ages and abilities.
This polymer product comes in a powder form and when mixed with water grows to more than one hundred times its size to create a wonderful sensory product with the look and feel of real snow. I use the twist-top Nancy™ bottles (NANTWS) filled with approximately 4 ounces of cold water and about ½ scoop of the powder to produce about two cups of snow. You can use water at room temperature, but if you use cold water it really feels like snow. I love the reaction of someone touching it for the first time. I hear comments like, “Oh, it’s really cold to the touch!” or “It really feels like snow!”
There are many fun ways to incorporate Insta-Snow® into your daily lessons. I love lessons that can cross curriculum areas such as math, science, language arts, geography and art. Here are some of the things I have done with students. To begin, I have two students paired at a 14” x 8 1/2” tub. I like the translucent bins with lids in clear (BBCL, BBLCL) or aqua (BBCA, BBLCA). One student will measure out 1/4 scoop of Insta-Snow® powder. The second student will hold his hands cupped together over the bin. The powder is poured into the second student’s hands along with about 2 ounces of water from the twist-top Nancy™ bottle. After the snow has formed, we repeat the process, allowing the students to switch roles. This gives each student an opportunity to measure the substance and feel the chemical change taking place in her hands. When both students have completed the process, I have them repeat it. But this time, instead of using plain cold water in the Nancy™ bottles, fill them with one of two primary colors of Liquid Watercolor™: red, blue, or yellow. For example, one student may use blue and the other student may use yellow. When they each add their colors, the snow will begin to turn green because blue and yellow make green. They have just completed both a science lesson on chemical change and an art lesson on color-mixing.
We take the project a step further by putting a lid on the container. The bins have a nice slot for an index card, so I like to label the bins with the student’s name and the date on which we did the project. We set the bins on a shelf in the room, and each day we graph how long it takes to begin to see condensation on the lid. We discuss absorption and how the water is separating from the powder. This is a great way to introduce academic language and teach basic math graphing skills.
During the weeks we are watching the condensation, we may also introduce a literacy lesson and read stories with a snowy setting or write a story or poem about snow. We many also look at our classroom maps or globes and discuss regions that get snowfall and those that don’t.
So, if you are looking for a great hands-on activity for the classroom, let it snow, let it snow, let it snow…Insta-Snow®, that is! Your students will love it.
