Objective

By the end of this lesson, you will understand how the reproductive system works, how babies are made through genetics, and the role of DNA in the process.

Materials and Prep

• Pen and paper
• Internet access for research
• Basic knowledge of human anatomy

Activities

1. Research and Draw

   Use the internet or any available resources to research the reproductive system. Take notes on the different parts and their functions. Then, draw a labeled diagram of the male and female reproductive systems.

2. Create a Baby

   Imagine you are going to create a baby with specific traits using genetics. Write down the traits you want your baby to have, such as eye color, hair color, and height. Use Punnett squares to determine the possible combinations of traits based on the parents' genetics.

3. Explore DNA

   Learn about DNA and its role in determining our traits. Research how DNA is passed down from parents to children. Create a simple model of a DNA molecule using colored beads or paper strips to represent the different nucleotides.

Third Grade Talking Points

• "The reproductive system is responsible for creating new life. It involves different parts in both males and females."
• "Babies inherit traits from their parents, such as eye color, hair color, and height. These traits are determined by our genes."
• "Genes are small units of information that are passed down from parents to children. They are located on structures called chromosomes."
• "DNA, or deoxyribonucleic acid, is the material that carries our genes. It is like a set of instructions that determines how our bodies grow and develop."
• "DNA is made up of four different building blocks called nucleotides. These nucleotides form a double helix structure, like a twisted ladder."
• "By understanding how the reproductive system, genetics, and DNA work together, we can learn more about how babies are made and why we look the way we do."
