DNA & Genes
Describe the double helix structure of DNA (base pairs, complementarity), explain how genes are sections of DNA that code for proteins, introduce the central dogma (DNA → mRNA → protein) conceptually, and discuss the ethical implications of CRISPR gene editing — including potential benefits (genetic disease treatment) and concerns (germline editing, 'designer babies')
Lesson
Set out your lesson
“DNA & Genes means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.”
Bring to the table
- A simple body outline printout or drawing
- Pencil and labels
Extra for the adult
Worked example. The brain sends signals so muscles know when to move.
Optional challenge. For DNA & Genes, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples DNA & Genes, not mastery.

DNA & Genes means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.
Materials: A simple body outline printout or drawing; Pencil and labels. 1. Say the goal of DNA & Genes in plain words once. 2. Adult points to one organ or system and names its job in plain words. 3. Child labels three parts and says the job of each. 4. Fresh check: one fresh organ/system job. Record and stop. Done: three correct labels with a job sentence each. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.

Check understanding
- Describes DNA as a double helix with four bases (A, T, C, G) where A pairs with T and C pairs with G
- Explains that a gene is a section of DNA that codes for a specific protein, and that proteins carry out most of the body's functions
- Describes CRISPR as a molecular tool that can cut and edit DNA sequences, and raises at least two distinct ethical considerations about its use in humans
“If your child heard that scientists have edited a human gene to prevent a hereditary disease, could they explain what DNA actually is, how genes work, and why some people think editing human DNA raises serious ethical questions?”
