Out of all of my kits, this is one of my students' favorites! It works especially well when I have students take turns doing the modeling; I also force them to take notes that include sketches.
I have included printables that will allow you to make six classroom kits (plus a few extra copies of the smaller pieces just in case). Because the components of this kit have to move and interact with each other, you will want to laminate everything rather than just use paper and tape (step-by-step printing and assembly instructions are provided).
The ribosome component measures approximately 7.25 in x 9.25 in, and with a little bending of the mRNA molecule, each kit fits in a gallon ziploc bag for transportation and storage. Please do NOT resize any of the components, or they will no longer work together!
Each kit comes with a small codon table with step-by-step instructions printed on the back. It takes a while to put this together, but by laminating and using velcro your kit will be surprisingly durable. I have re-used my kit for several years now, and it has held up very well. Not to mention my students tell me they really appreciate it when I go the extra mile. Totally worth the higher grades on the test!
