This one takes a little prep work the first time 'round. But after that, you're set forever. It's a great way to include a little kinesthetic activity into the study of DNA. First, the prep work: On a long strip of paper* write out a string of DNA bases (actually, you're making the mRNA). You want to make sure your letters are evenly spaced - I actually marked the paper. Keep a codon chart handy - make sure you begin with a start codon and don't come to a stop codon immediately. And, don't make the mistake of using T instead of U, as someone did... Now you need to make a ribosome through which your strip of paper can fit. I made mine out of fun foam. It has magnets on the back, so it sticks to the white board. Cut the window in the ribosome, so that you can see 3 bases at a time (hence the reason for evenly spacing your letters). Use this picture to guide you: Now you need to make the amino acids. Once again I used fun foam. I wrote the amino acid on the foam, punched holes in it and strung string through the holes so the students could wear them. For the activity: Draw a huge circle on the board - a cell. Sketch in a nucleus and stick your ribosome in the middle as well. Show your students the mRNA (your paper strip) moving from the nucleus to the ribosome. Feed the mRNA into the ribosome. Have your students translate the first 3 mRNA bases into an amino acid. Have a student put the appropriate amino acid placard on and stand in front of the room. Move the mRNA to the next three bases. Determine the amino acid. Have another student put on the appropriate placard, then stand next to the first student and hold his/her hand. Proceed this way until you come to a stop codon, or until you've made your point. Your students will have a better feel for how a ribosome translates mRNA, how proteins are formed, and understand that proteins are long chains of amino acids. * I got a few sentence strips from an elementary teacher in my building - they're the perfect size and shape for this, I didn't have to cut them, and they have lines marked on them! ****** I learned this from a fellow teacher at a NJ Science Teachers Association Convention several years ago. I don't know who that teacher is - but if you're out there, please let me know - I'd like to give you credit.

This week I'm sharing a packet of materials on using and making dichotomous keys. You'll find a page of informational text, directions for using a key, directions for making a key, and two different student worksheets. Here's a sneak peak at the contents. Download Dichotomous Keys. I hope you get a chance to use these in your home or classroom. Please let me know if you try these and how you like them! **Updated January 2019.

Learning the levels of organization, that is! My students are working hard on our living systems unit. Our newest anchor chart is all about the organization of living things. I am a huge fan of anchor charts because it helps my students organize the content into bite sized pieces. In our living systems unit we discuss the levels of organization, plant and animal cells, classification and cell theory. I like to make an anchor chart for each of the different topics and hang them around the room as we complete them. Even more than that, I like the students to have their own copies of each anchor chart. So while I'm building a big one, they are making a smaller version at their desks. The levels of organization student version has all the boxes, but they're all mixed up. The students first figure out which boxes go together and then color those boxes to match. Once colored they are cut and pasted to the empty boxes on the final page. I love that my students end a unit with a set of anchor charts all their own. By the end of the year they have a nice science collection, highlighting the content they learned in a way that's easy to reference and, hopefully, easy to remember!
