Homework is due TOMORROW. It's the front and back multiple choice page. Make sure you use your strategies!
Today we learned about how to determine variables and constants in an experiment. We conducted an experiment with limonene, water, and packing peanuts. Limonene is found in citrus fruits and cleaning supplies. We asked the question, "You want to ship limonene in a box with cushioning. What is the best packing material to mail limonene?"
We observed that Styrofoam packing peanuts dissolved when they were touched by limonene but they were unaffected by water. On the other hand, the corn starch packing peanuts dissolved when touched by water but were unaffected by limonene. We are going to see what acetone does to polystyrene tomorrow and also practice identifying constants and variables in an experiment.

Grace has a cousin who has studied in Hawaii and Australia. Go to her cousin's website for interesting facts, info and pictures of aquatic life, reptiles and amphibians. He came and spoke at Assembly in the past. He's really cool!
