This is a fun, versatile set that can help students learn about DNA structure. That is, provided you pay attention to which pieces are intended to model which structures. If you are just following the booklet diagrams without drawing a clear mental connection between plastic parts and real-life sugar-phosphate backbone, nitrogenous bases, and hydrogen bonds, then I expect you will enjoy the activity, but it won't be especially reinforcing for you.
What's great: the sturdy, resealable storage box with snap-on lid! All the plastic pieces can easily fit in sandwich or quart zip-bags, if you want to do that. Multiple sets stack nicely for storage. However, the sticker on the semi-transparent lid can be a hassle to get off. A cardstock sleeve would have been better.
One good touch: in the DNA replication exercise, the original deoxyribose sugars, represented by grey, half-snowflake pieces, are matched with strands that use yellow pieces for the sugars instead. The resulting new strands look obviously half-new, half-old, nicely modeling the semi-conservative concept. There are enough pieces in a single set to create the 12-base pair, double-stranded DNA molecule as shown, and then replicate it into two new, semi-conservative strands, then create some complementary mRNA strands.
Unfortunately, the design (modeling choices) and booklet could use some tweaks.
1. The designers chose to represent the RNA base uracil with the same purple rods used to model phosphate groups. Not a good choice.Read more ›
. There are likeable features about this kit, the minute you open that Plastic Storage Box it comes in.
(A) The instructions are printed in huge print on a giant booklet about the size of full
sheet of 8-1/2" X 11" paper.
(B) The instructions are in vivid color. It does not come with large wordy passages of information.
The instructions for the construction of the Double Helix are in huge print, that even those with difficulty reading small print, will find easy to read and follow.
(C) On the very back of the big instruction book, are very large pictures of each type of part.
(D) The parts (Nucleotides) are large and there are Five Hundred and Twenty Five (525) pieces in total to work with.
(E) When you are done working with the parts and book, you put it all back in the plastic storage Case and snap the plastic lid back on. That is a very nice feature. It saves about $10.00 for an additional storage container purchase.
I rate this product pretty good. It is designed for Ages 10 and up (or Grades 5-9) and it is easy to work with. The Ten and UP age bracket seems to be the market standard for these things, although I think that this model would be useful for more advanced ages. The parts more closely resemble the real thing.
There is no "lab equipment" with this kit and there is nothing about the familiar Tomato Experiment; but as a model of the Double Helix of DNA to study, it is very good to work with.
It comes with a DVD as a "Teacher's Guide".
Also, I called the company with some questions, and they did take the time to talk to me and answer everything.
