Bell-ringer: 7 minutes Evaluate the successfulness and effectiveness of the given procedure. What else could you include to improve the written procedure? Laura is studying a species of fish living around an ocean reef system. She lists the following observations: • Males have brightly colored scales to attract the females for mating. • Females are brown without brightly colored scales. • The fish species normally has few predators. • Within a few months, a species of carnivores enters the reef system area. • These carnivores prey upon the colorful fish. Laura measured the population size of the fish species a year after the introduction of the predators. Copy CCSS/Objectives/HW

Lab Safety Contracts 9/4/15 Guardian Version I acknowledge that my student, __________________, is collecting data for a science project for Miss Krichten’s Science class for the week or until completed. I may supervise if needed or will find someone else to if needed. I know that animals should not be harmed, chemicals are not required, and no one should be at risk for being harmed during the project. If there is any concern, I will call Miss Krichten at 215-595-3375 right away. Guardian Signature: ___________________ Date: __________

Lab Safety Contracts 9/4/15 Student Version I acknowledge that I, __________________, am only to be collecting data for a science project for Miss Krichten’s Science class for the week or until completed. I will ask to be supervised by my guardian. I have learned the lab safety rules in class and will follow them at home. I know that animals should not be harmed, chemicals are not required, and no one should be at risk for being harmed during the project. If there is any concern, I will call Miss Krichten at 215-595-3375 right away. Student Signature: ___________________ Date: __________

Your Turn Project #1: Lab Safety Cartoon This is an individual project. Create a cartoon which depicts any lab safety rule. Your cartoon must clearly explain what is happening and either how to prevent an accident or what to do if there is an accident Project #2: Lab Safety Skit You may work in a group up to 4 people to act out any lab safety rule. Your skit must clearly explain what is happening and how to prevent an accident. You may use different characters and scenarios to describe what is happening. Project #3: Lab Safety Poster Your safety poster must clearly explain the rule and how to prevent an accident. The brochure will need sketches, or pictures that will help aid in your explanation. The picture must fill at least one third of the poster board.
