Cell Division & Genetics
Organisms reproduce either asexually or sexually. Asexual reproduction produces offspring that are genetically identical. Sexually reproductive organisms produce offspring that are different. Gregor Mendel, the "father of genetics", discovered how heredity works and how traits are passed on by breeding pea plants. He said that the different forms of a gene, or alleles, can be either dominant or recessive. You can use a Punnett square to show the probability of an offspring having a certain trait by crossing the alleles of the parents.

Work, Power, & Simple Machines
Students are learning how to make work easier by using simple machines. All complex machines are made up of combinations of the six simple machines working together.
