Guided Discussion:
"How might an understanding of DNA be incorporated into a unit about animal
life cycles in a meaningful way at the K?6 level? "
Create a book of instructions for building a Lego man. Make one for each
child, but have them be slightly different, such as different hats, shirts,
heads, etc. Maintain a set amount of characteristics. Have 2 students pick
half of their characteristics and copy them to a new book. Bind the 2 half
books together, and use it to create a new Lego man.
Of course the book is the DNA, the characteristics are genes. The combining
of 2 books is the reproduction.
- wow. That is a great idea, I amaze myself sometimes !
Is this possible?
The students may understand the symbolism, mostly only the 4-6 grades
 Why or why not?
Young children have difficulty with symbols because it is abstract thinking
and their brains are not fully developed yet.
DNA isn?t something with which K?6 students are likely to have had any
direct experience (the Kiwi fruit extraction can help here).
I agree - use the Kiwi fruit extraction too.
