What is your experience with science labs?

• I have never scienced in my life

• I have done a few very simple lab activities

• I have done lab activities on a regular basis

• I'm a lab pro.

Labs

• In science, we often learn the most information by carrying out experiments

  • Science is a verb

• Experiments can be a great learning tool but need to be treated appropriately so that everyone gets the most out of them

  • Some experiments can be dangerous and need to be treated as so.

• Labs can be short activities or multiday experiments depending on the topic

Lab Safety

  • You and your parent/guardians must fill both out for you to participate in labs

    • One copy stays in your binder, One Ms. Fancsali keeps for the school records

• You must take a safety quiz and score a 100% before you can do labs for the rest of the year

• Failure to follow the rules set by the safety contract will result in:

  • A zero on the lab with no chance to redo

  • A detention

  • Ms. Fancsali Contacting your parents about it

• Permanent removal from lab activities will occur for Multiple/Extreme offenses

Lab Attire

• Different labs require different materials, but some things will be required in most labs

• At all times

  • Safety Goggles must be worn
