Warm Ups

Wednesday - 9/1 What do you think of when you hear the word chemical?
2. Make a list of any chemical you can think of. Are there any you would like to live without or any you cannot live without? If so which ones?

Thursday - 9/2 Look up the word property in your textbook glossary
2. Name some properties you would use to tell the difference between a banana and a ham sandwich. Try to think of properties that could be used to tell any banana from any ham sandwich.

Friday - 9/3 What is a law? What is a theory?
What is the big difference between the two?

Tuesday – 9/7 No warm up – LAB
1. Grab a lab w/s and READ the introduction 2. In your notebook write the TITLE of the lab at the top 3. Write a hypothesis for the lab in your notebook

Wednesday - 9/8 Identify the problem with the following experiment.
What would you do to fix it? Sponge Bob notices that his pal Gary is suffering from slimotosis, which occurs when the shell develops a nasty slime and gives off a horrible odor. His friend Patrick tells him that rubbing seaweed on the shell is the perfect cure, while Sandy says that drinking Dr. Kelp will be a better cure. SpongeBob decides to test this cure by rubbing Gary with seaweed for 1 week and having him drink Dr. Kelp. After a week of treatment, the slime is gone and Gary’s shell smells better.

Thursday – 9/9 Identify the dependent and independent variables in the following experiment SpongeBob noticed that his favorite pants were not as clean as they used to be. His friend Sandy told him that he should try using Clean-O detergent, a new laundry soap she found at Sail-Mart. SpongeBob made sure to wash one pair of pants in plain water and another pair in water with the Clean-O detergent. After washing both pairs of pants a total of three times, the pants washed in the Clean-O detergent did not appear to be any cleaner than the pants washed in plain water
