![]() I find this option to be difficult at the beginning when small group skills are still being developed. We will set up 6 different science stations, and put one group at each station. ![]() If we are completing this unit in the 2nd half of the year, I tend to lean towards this option. For students who are comfortable working independently in small groups, this one is my personal favorite. The next day, set up two different sets of stations. This also reduces the number of different Science experiments you have to manage and set up at one time. Set up three ‘A’ stations, and three ‘B’ stations, and divide your students into 6 groups). Set up only one or two stations, with multiple stations of each. Then complete the stations over a number of different days. Chemical changes involve the rearrangement of molecules or atoms and result in the pro-duction of one or more new substances. A chemical change is defined as a change in the composition and properties of a substance. This one works best if your class is a little less mature and you feel they will need a lot of guidance to move through the stations. Scientists classify changes in matter as either a chemical change or a physical change. Set up six identical stations and have all students complete the same station at the same time. Do you know which ones are which Roll the clay into a ball Flatten it Make a clay animal figure Flatten it or roll it into a ball Is this a physical or chemical change Pour 1 cup of water in a pan, put it on the stove, turn on the heat. Each one shows a physical or chemical change. This lesson can be extended to introduce. NOTE: This experiment is actually a series of experiments. There are a few different ways you can do science stations in an early elementary classroom. By making goofy putty, students learn about measurement, mixtures, solutions, physical changes, and chemical reactions. I set up six different stations in the class, and we rotate through them. Using science stations gives my little scientists a chance to use the scientific method ( that we learned about here!) to test what they know about changes and decide if their experiment resulted in a physical or chemical change. My BEST way to help students to really discern the difference between a chemical and physical change is to try it out in as many experiments as possible. Use science stations to give a real-life experience ![]()
