Customer Reviews

Kinesthetic value for teaching DNA functions
Students definitely respond positively to this K’Nex model! It allows physical demonstration of not only the structure of DNA, but also replication and transcription. “Breaking” the hydrogen bonds, copying the template, even imagining how the ribosome reads the RNA for protein synthesis are much easier for students to comprehend with K’Nex.

Good idea but not a large quantity
I used this product with high schoolers taking level biology. I thought the hands on approach was fantastic. I was disapointed in the quantity inside each kit. I needed two kits to cover a room and my classes were on the small side. For the cost I think that the total number of small kits that can be made is disapointing.

BIG INSTRUCTIONS, LOTS OF BIG PARTS

. 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 produce 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.

My son loves it
My 9 year old son loves K’Nex and built this car by himself in a couple of hours. He loves taking it apart and modifying the body. It comes with a motor, but if the car hits a wall (not recommended) parts will come off.

Customer Reviews

Great for kids who love to build things
I bought this for my 7-year-old son for Christmas and he loved it. He couldn’t wait to dive into the box and start building. He put it together all by himself. The two ferris wheels spin in opposite directions and the motor is strong enough to put a few small toys (he used imaginext knights)in the seats and watch them go around. The ferris wheel is huge though, so when left together, it takes up a lot of space.

An excellent toy for careful children
This toy is like a puzzle. You do it the first time and it takes you time and you have a lot of fun. The secound time you do it much faster and the fun doesn’t last so long. Plus if you haven’t been careful with the tinny pieces, you won’t be able to finish it because there is almost exactly the number of pieces you need.
