Lean, Mean Information Machine: Using a Simple Model to Learn about Chromosomal DNA
Source Institutions
Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.
String Genome
Source Institutions
In this biology activity (page 5 of the PDF), learners use yarn and sticky labels to build a model of a DNA strand. They discover that DNA is very long, very skinny, and packs well into cells.
DNA Modeling Activity
Source Institutions
Using pipe cleaners, straws, and beads, learners explore the building blocks of life by creating their own model of DNA.
Life Size: What's in a microbe?
Source Institutions
In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.
Inside DNA
Source Institutions
In this activity (on pages 34-39), learners make a fairly detailed model of DNA using licorice and gumdrops.
Breakfast Proteins
Source Institutions
In this activity, learners construct a cereal chain as a model of how proteins are made in the cell.
Gene Switches
Source Institutions
In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.
The Ladder of Life
Source Institutions
In this activity, learners identify the DNA base bars guanine, cytosine, thymine and adenine. Learners create a DNA model using colored paper clips to resemble these base pairs.
