Breakfast Proteins
Source Institutions
In this activity, learners construct a cereal chain as a model of how proteins are made in the cell.
Wheat Germ DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from wheat germ using simple materials.
A Simply Fruity DNA Extraction
Source Institutions
In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.
Home Molecular Genetics
Source Institutions
In this activity, learners extract DNA from their own cheek cells, then create a rudimentary DNA profile similar to those seen on crime scene dramas.
Life Size: Line 'em up!
Source Institutions
In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.
Close, Closer, Closest
Source Institutions
In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.
Reading DNA
Source Institutions
In this activity, learners use edible models of the DNA molecule to transcribe an mRNA sequence, and then translate it into a protein.
DNA and Histone Model
Source Institutions
In this activity, learners construct a 3-D paper model depicting how histone, acetyl and methyl molecules control access to DNA and affect gene DNA expression.
Have Your DNA and Eat It Too
Source Institutions
In this activity, learners build edible models of DNA, while learning basic DNA structure and the rules of base pairing.
Onion DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.
Virus Lander
Source Institutions
Can you avoid the body's immune system and make someone sick? Play this online game in which you go inside a human body to explore how viruses attack cells in the body.
Homologous Shoes?
Source Institutions
This "concept demonstration" provides learners with a concrete example (a pair of shoes in a classroom "cell") of what homology means.
Restriction Enzyme Digestion: How does it work? Why is it useful?
Source Institutions
In this activity related to plant biotechnology, learners use restriction enzymes to cut up DNA from a virus called Bacteriophage λ, a process known as restriction digestion.
Yeast DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from yeast using simple materials.
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.
What Sort?
Source Institutions
In this activity (on pages 22-33), learners do the kind of work genetic scientists do, sorting and comparing (images of) genetic material strands called chromosomes.
Microarrays and Stem Cells
Source Institutions
In this activity, learners use microarray technology to determine which genes are turned on and off at various points in the differentiation of pluripotent stem cells on their way to becoming pancreat
Exploring Structures: DNA
Source Institutions
In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.
Protein Factory
Source Institutions
In this activity, learners take on the role of various parts of the cell in order to model the process of protein synthesis.
Born of Blood: Craft Stick Chromosomes
Source Institutions
In this activity, learners work in groups to match craft sticks that represent chromosomes. Learners must define critical attributes of their chromosomes as they look for matching chromosomes.
