Prepare for lesson:
- Review Breakfast Proteins activity guide
- Supplies:
- Small box of colored, donut shaped cereal like Fruit Loops or Fruity Cheerios
- Cups
- Chenille stems
- String
- Pencils
- Paper
- Identify what colors exist for cereal, think of ideas for a possible code with the colors
During the lesson:
- Show the class all the cereal colors. With them, decide on a code with at least 20 letters (or you can design a code beforehand).
- Note legend: Y is yellow, Red is R, Green is G, etc.
- Tape the code on a wall in the corner of the room. Provide pencils and paper near the code. Section the code area with string/rope.
- Give youth 15 minutes to complete using only the cereal they are given.
- Have youth work in small groups, one person writes the code down, another collects a cup of cereal and chenille stems.
- Together, or individually, youth replicate the code with cereal.
- As a class, youth compare their cereal chains.
- Is everyone’s the same?
- How many were able to successfully copy the code? Turn that number into a percentage. What percentage is that?
- What are some reasons for the errors? May share that the handwritten note was copied wrong, not enough cereal in the right color, not enough time.
- Share that this is a process our genes go through.
- The copying process is called transcription.
- The handwritten notes are RNA.
- When our DNA is copied, sometimes it’s not copied right, and we get something different. Ask if anyone knows what that’s called? (Mutation)
- Can anyone think of real-life examples of a mutation?
