DNA Extraction: Look at your genes!
Source Institutions
Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.
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.
Gene Switches
Source Institutions
In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.
Not Just A Bag Of Beans
Source Institutions
In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.
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.
Multifactorial Inheritance
Source Institutions
In this biology activity (page 6 of the PDF), learners roll a die to create a simple model that teaches them about the factors contributing to heart disease.
Risk Continuum
Source Institutions
This activity is a whole-group kinesthetic demonstration that shows learners what it means to be in a "risk group" for developing heart disease based on family history and genetics.
Pick the Risk: The Polygenic Pedigree Challenge
Source Institutions
In this activity, learners are challenged to track and record the passage of colored pom poms (representing genes) through generations of a family using a pedigree.
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.
Scavenger Hunt: A Group Collection
Source Institutions
In this activity, learners are divided into teams.
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.
The Beaks of the Finches
Source Institutions
In this simulation, learners become birds different beak types. Learners use various tools to represent beaks to pick up seeds and place them in a petri dish.
Wear a Chimp on Your Wrist
Source Institutions
Learners construct a bracelet containing two strands of beads, which represents a double strand of DNA that codes for a gene. They match beads to the bases in a section of a chimp's DNA code.
Yeast DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from yeast using simple materials.
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
What's the Risk?
Source Institutions
To discover the risk and protective factors involved in substance addiction, learners play a game of chance to determine whether a fictitious child is likely or unlikely to abuse drugs.
Making Babies
Source Institutions
This activity is designed to introduce learners to genes, genotypes and simple inheritance patterns.
