Wielded with my 40% off coupon, I picked up this little gem for about $12.00. It is regularly priced at $19.99 (still a bargain). It included all of the pieces necessary to build the DNA ladder and Double Helix (that I was going to be purchasing the other kit for), and included all the materials necessary to do some DNA extractions (both vegetable/fruit and HUMAN), a chromosome puzzle and karyotyping. It was a bargain for all we could do with it!

The 40-page booklet that came with the kit not only included the instructions for all of the projects, but also acted as a mini-textbook with introductory material about cells, nuclei, DNA, chromosomes, and genes. The instructions for the projects were straightforward and easy to follow, set forth in a step-by-step fashion with illustrations. All of the projects went off without a hitch. The illustrations were clear, concise, colorful, and entertaining.

Dawson is in the 9th grade, and the projects were all challenging enough for him. And they were difficult enough that he actually had to spend some concentrated time on them. What I mean is: He certainly could have used my help, but when I refused he was able to dig deep and figure it out for himself. I would say this kit would be perfect for a 6th grade student (with some adult help) up through any high school biology student.
|The hardest part of the Human DNA Extraction was keeping the water between 50 and 55 degrees for 12 minutes.|
|Swishing the cells into the solution. Watch out CSI.|
|Still monitoring the temp.|
The DNA kit can be purchased in Hobby Lobby stores, at HobbyLobby.com, and directly from the ScienceWiz site.
For the money, this kit is excellent! I would certainly recommend it for any educator teaching about DNA. I am happy that I decided to purchase this kit instead of shelling out the $50 for the other comparable kit.
(And, now we have some test tubes and other materials we can use in other experiments!)
