DW does the Bohr’s Model Montessori Style

We’ve been doing some chemistry work – mainly to understand the Periodic Table of Elements.

JV and Ms. JW worked and created this beautiful way of looking at the electrons. Today DW pulled the work out and began to look for the shells.

    How lovely and fun. Are the silver concentric circles paint or duct tape?…

    I’m curious how you start to talk to your class about chemistry. What are your introductory lessons? I’m a new upper elementary teacher and think they children would love this, but not sure how to get started exploring.

      Thanks for you question.

      I do the stellar nucleosynthesis lesson in before I do the clock of eras with lower els and then before I do the review of the timeline of life in upper. (https://eavice.wordpress.com/2010/09/23/stellar-nucleosynthesis-and-lower-el-kids/). I have always found that this discussion of elements seems natural to the children when it is viewed from the lens of the creation of H on up. There is a reason. Sometimes it comes out in sewing their own quilt. I’ve had kids help me embroider all the elements on the last explosion felt pieces and we discussed elements that they would then go research. Sometimes we’ve gathered pictures or objects that we then took pictures of that are PURE elements creating a giant periodic table on the wall in the hall. (About half the class will split off into the categorization of stars.That is chemistry too [Astrochemistry])

      Chemistry often comes as far as acids and bases through botany. Can’t skip botany. Soil tests. Acidity of root tips. All that leads to ph strips on everything they can try. Great for graphing and sorting in math.

      When we look at the thermometer and think about C and F. I always throw in Kelvins. I’ll often tell his story and the I Wonder story of what would happen if we got an element to absolute zero. Then that is a natural segue to electrons. I think one year we got there off of flickering florescent tubes. Sometimes I’ve blown third years away with the idea that there are things smaller than the single piece of the element called an atom. We just approach it rather traditionally with a lesson and that is when we start the Bohr’s model. The third and fourth years tend to really get into it – especially when the upper shells start messing with their “rules.” That is when you use electric currents to rust a nail quickly etc. This also brings up types of chemical reactions.

      In math in 6th year, we’ll balance chemical reactions.

      When we look at Renaissance civilization I’ll tell the story of Newton and Lebeniz (the beginning of calculus) but I’ll throw out some other names – Pascal, Bacon, Copernicus, Kepler, the microscope guy (can’t recall his name at the moment) etc. Crazy guys with great hooks to get students interested. Always will get one or two projects.

      I love Caveman Chemistry. It is an odd book but the chapters offer neat project based discussions.

      My other secret weapon is: http://www.ellenjmchenry.com I have both her chemistry and organic chemistry books. When Dr. Montessori wrote some of the lessons, science wasn’t where it is today. My training was very strict AMI. I work hard to get the principals needed and then augment with other materials. (I have her map book, too, because I found that second year uppers like to draw their own maps of the world.) The elements games we play are from her material and very Montessori.

      OK that was a lot of brain dump. Let me know how to help explain my thought. Lots of random info.
