Meiosis: Making Sex Cells (Part 3).
🎯 Your mission
Predict it first. Then prove yourself right (or wrong).
⚡ The twist
Nature loves to surprise the careful watcher.
Mind = Blown
🔬 The more you look, the more nature shows you.
Make a hypothesis first
Before you start: write down what you think will happen, and why.
What You'll Learn
Meiosis is a special type of cell division that produces sex cells (gametes) with half the normal number of chromosomes. When egg and sperm unite, the full number is restored.
Key Words
- gene
- chromosome
- mitosis
Materials Needed
- microscope (or magnifying glass)
- slides
- onion skin
- iodine stain
- paper
- colored pencils
Safety First
- Keep small objects away from young children.
- Work in a well-ventilated area when using vinegar or other strong-smelling substances.
- Dispose of materials properly after the experiment.
Steps
Read about Heredity and write down three key facts.
Create a Punnett square to predict the offspring of two parents. Use a trait like eye color or seed shape. Calculate the probability of each outcome.
Compare the before and after states.
Write your conclusion: did the results match your hypothesis? What would you change next time?
