In this activity, learners construct a cereal chain as a model of how proteins are made in the cell.

This laboratory exercise is designed to show learners how DNA can easily be extracted from wheat germ using simple materials.

In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.

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.

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.

In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

In this activity, learners use edible models of the DNA molecule to transcribe an mRNA sequence, and then translate it into a protein.

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.

In this activity, learners build edible models of DNA, while learning basic DNA structure and the rules of base pairing.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.

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.

This "concept demonstration" provides learners with a concrete example (a pair of shoes in a classroom "cell") of what homology means.

This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution.

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.

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.

This laboratory exercise is designed to show learners how DNA can easily be extracted from yeast using simple materials.

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.

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.
