A quick review... DNA provides instructions for the assembly of amino acids into protein. Therefore... Similar proteins have a similar amino acid sequence. And if the amino acid sequence is similar, the DNA is similar. Scientists believe that similar DNA sequences indicate a common origin. Hemoglobin (a protein in red blood cells) is one protein that has been studied in humans, gorillas, and horses. Procedure: Each group will be given 10 different colors of beads (each one representing a different amino acid - see list below). Students use the beads to create the partial amino acid sequence for human, gorilla and horse hemoglobin (see below). For assembly purposes, I give the students an index card with three pipe cleaners attached. It keeps it all in one place, and it makes it easy for the students to compare the sequences at the end. After students have completed the amino acid sequences, I use my keys to quickly check their work. They then count and record the differences in the amino acid sequence. From there, you can discuss... --what determines the order of amino acids? --where do we get our DNA from? --where did our parents get their DNA from? --random chnages in DNA occur over time, the mroe time passes, the more changes there will be. At the end of the activity, students remove thier beads and return them to their appropriate bag. The Amino Acid Sequences: Human: gly lys val asp val asp glu val gly gly glu lys leu his val asp pro glu asp phe arg leu Gorilla: gly lys val asp val asp glu val gly gly glu lys leu his val asp pro glu asp phe leu leu Horse: asp lys val asp glu glu glu val gly gly glu lys leu his val asp pro glu asp phe arg leu ****** This activity comes from a wonderfully creative and talented teacher who presented it in a workshop at the New Jersey Science Teachers Association Convention. Unfortunately, I don't have her name written down. If you know her, or are her, please contact me and I will give her all the credit in the world for this great activity!

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! The Let's Build: Levels of Organization Anchor Chart can be found here. The Let's Build: Levels of Organization student version can be found here.

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.
