Day 3 - Inherited and Acquired Traits
Make graphic organizer with 2 pockets for:
List traits on cards to sort into pockets:
|Inherited Traits||Acquired Traits|
|rolled tongue||how to ride a bicycle|
|widow's peak||chicken pox marks|
|free or attached earlobe||tooth with cavity|
|cleft chin||black eye|
|coloring (eyes, hair, skin)||sun tan|
|bushy eyebrows||ability to read|
Ten Questions on Inherited or Acquired Traits http://training.sedc.k12.ut.us/sci78/7/apr/acquired_inherited_traits.pdf
Discussion and Graphic Organizer
Experiment "Boy or Girl?"
Explain to students that gender is determined by chromosomes that are inherited from parents. If an organism inherits two X chromosome, it will be female. If the organism inherits and X and Y chromosome it will be male. Complete the following experiment. (Marked one lima bean with a Y on one side and an X on the other. On another mark an X on both sides. Shake the beans and drop them on a desk. Record the results on a chart. After 10 times discuss.)
