DRUGS DAMAGE DNADate: • Drugs are substances that change normal bodily function. • All of the following illegal drugs damage DNA (can harm the person and/or the offspring) • Can cause unconsciousness, vomiting, brain damage and death • Examples: alcohol, heroin, marijuana • Can cause seizures, headaches, paranoia, cancer, and death • Examples: caffeine* (not too bad for DNA), nicotine (cigarettes), cocaine • Can cause panic, feeling of losing touch with reality, nervous system damage, death • Examples: LSD, mushrooms, XTC • Using drugs now can shorten your lifespan. Summary:
II. All Illegal Drugs Damage DNA • Why is DNA damage bad?

Summary:
Types of Drugs, and What They Do to you. A. Depressants slow you down • cause unconsciousness, vomiting, brain damage and death • Examples: alcohol, heroin, marijuana
DRUGS DAMAGE DNADate: • Drugs are substances that change normal bodily function. • All of the following illegal drugs damage DNA (can harm the person and/or the offspring) • Depressants cause unconsciousness, vomiting, brain damage and death • Examples: alcohol, heroin, marijuana • Stimulants cause seizures, headaches, paranoia, cancer, and death • Examples: caffeine* (not too bad for DNA), nicotine (cigarettes), cocaine • Hallucinogens cause panic, feeling of losing touch with reality, nervous system damage, death • Examples: LSD, mushrooms, XTC • Using drugs now can shorten your lifespan. Summary:
Types of Drugs, and What They Do to you. B. Stimulants speed you up. • cause seizures, headaches, paranoia, cancer, and death • Examples: caffeine* (not too bad for DNA), nicotine (cigarettes), cocaine

Summary:
GP: Think, Pair, Share 1. Melanie is at a club in the city. A stranger offers her some XTC. What scientific information could she use to help her make a decision about using this drug?
GP: Think, Pair, Share 2. Abraham is hanging out with some friends. A stranger approaches the group and offers them all some marijuana. What scientific evidence could Abraham tell his friends that could help them make this decision?
GP: Think, Pair, Share 3. Xavier is a miner in Chile. All of his co-workers use cocaine so they can stay awake in the mine and be less hungry. When he is offered cocaine, what scientific evidence could he use to help him make his decisions?
INP: 1. Frederick is hiking in the woods and finds some mushrooms. His friend tells him that eating these mushrooms will make him hallucinate. What scientific information could Frederick use to help him make a decision about using this drug?
INP: 2. A person is on a crowded street corner, where lots of people are taking a “cigarette break.” One of the person’s co-workers offers a cigarette to the person. What scientific information could the person use to help make a decision about using this drug?

Standards and Objectives Standard: II.II.II.6. Know that hereditary information is contained in genes that are located in chromosomes, including: -determination of traits by genes -traits determined by one or many genes -more than one trait sometimes influenced by a single gene. Content: SWBAT: Explain that inherited traits can be caused by many genes. Explain that inherited traits (more than one) can be caused by one gene.

Scientists found that genes do not always work like Mendel described. Mendel: One allele = one trait
Genetics Since G. Mendel Date: • Scientists found that genes do not always work like Mendel described. • More than one gene can cause one trait • Example: Eye color and height are caused by more than one gene. • More than one trait can be caused by one gene • Example: Chicken “Frizzle” disorder, Phenylketonuria (PKU) • The environment can play a role in gene expression • Example: Himalayan rabbits have genes that make their fur dark only at lower temperatures Summary:
A. More than one gene can cause one trait. Eye Color Human Height
