Student After students complete the worksheet have a class discussion products such to clarify their ideas. as CER, DI Menus Go over these points with the students: What did the toothpicks represent? What did the dots on the toothpicks represent? When you crossed the purple and the white flowers and got all purple offspring was it because the offspring only inherited the purple genes? What was the reason? Where are chromosomes found in a cell? What are chromosomes made of? Tell students: In your notebooks, look back at what you wrote at Explain the beginning of the lesson about how traits are passed from parents to children. Now write down what you have learned about the relationships between DNA, chromosomes, genes, and traits: Chromosomes are made of DNA. Sections of the chromosome are called genes. The genes determine traits in organisms. Heredity is the passing of the traits from one generation to another. Have students copy a diagram in their notebook similar to the one below to show the relationship between DNA, chromosomes, and genes: . You Do Research, To determine if students have a understanding of the Home concepts, have them create a model to show how they inherited Learning a trait from their parents such as tongue rolling, attached earlobes, or another of the traits that were discussed at the beginning of the lesson. Or have them continue to work with the purple and white genes in pea plants and answer these questions: Extend/ Elaborate What would be the possible offspring if you crossed a flower with a purple gene and a white one with a flower that had only white genes? Only purple genes? Could two white flowers produce plants with purple flowers? Why or why not? Exit Slip How are traits passed from parents to the children? If a child looks more like one parent than the other, does that mean that he/she inherited more genes from that parent than the other? Evaluate How are genes and chromosomes related?
