Lesson Plans

Standard 4

Students will understand that genetic information coded in DNA is passed from parents to offspring by sexual and asexual reproduction. The basic structure of DNA is the same in all living things. Changes in DNA may alter genetic expression.

Objective 3

Explain how the structure and replication of DNA are essential to heredity and protein synthesis.

• Biological Balderdash
  In this fun activity to introduce students to the vocabulary of protein synthesis the students will play "Balderdash." They will then demonstrate their knowledge by passing a short quiz.
• Biotech Timeline
  Students will use a reading to trace the accumulation of scientific knowledge concerning biotechnology.
• Building Genetics Vocabulary
  This activity gives students practice using genetics vocabulary words by matching them to definitions, pictures and examples. The students will create their own definitions, pictures and examples for other words.
• CSI (Crime Scene Investigation)
  Students will use a model of DNA electrophoresis to solve a "crime" in their classroom.
• Extracting DNA
  Students will learn to extract DNA from different cells and see what it looks like. Students will understand that genetic information coded in DNA is passed from parents to offspring by sexual and asexual reproduction.
• Find a Gene
  Students will use a model in the form of a jigsaw puzzle and corresponding pedigree to learn how genes are located. They will then use another pedigree and a more realistic model using chromosomes and gene pairs to locate another gene.
• Making Sentences of DNA
  In this activity students will model protein synthesis using sentences for DNA/RNA codes and words for amino acids. They will transcribe and translate the DNA into a sentence.
• Mutant Radishes
  Students will germinate radishes that that have been irradiated and determine what dosage of radiation will affect them.
• Origami DNA
  Students will use paper models of DNA, RNA and amino acids to form a protein chain.
• Protein Synthesis Models
  Students will understand that genetic information coded in DNA is passed from parents to offspring by sexual and asexual reproduction by making a working model of protein synthesis and display for the class.
• Sally's Candy Factory
  Student will use an analogy to learn about protein synthesis.
