In this activity, students review how human physical traits, such as eye color, are determined by specific segments of genes. Students will use basic crafts materials to build a simplified model of a pair of chromosomes that represents some of their own physical traits. Then students will compare and contrast their models, to determine which traits are most frequently found among their classmates and therefore can be called high frequency traits.
In this activity, students will assemble a small saltwater aquarium to raise and observe brine shrimp. Then students will observe and record the growth of brine shrimp through various stages of their life cycle, and examine their various anatomical features.
In this activity, students will learn about the two main types of fossils, body and trace fossils. Students will observe and examine a set of fossils to classify them as body fossils and trace fossils. Students also will act as paleontologists and try to identify each fossil.
Use household materials to investigate and explore your ability to smell an odor, then compare and contrast results to determine if some individuals have a better sense of smell than others. Observe the Maillard reaction and how different odor molecules are released into the air.
