3/13 - If you place an ice cube in a plastic bag and take its mass as 10 g, will the mass after the ice melts be greater than, less than, or equal to 10 g?
Unit 3 - Cells
10/17 - What kinds of differences did you see on Friday between the plant cells and animal cells you looked at under the microscope?
10/19 - Explain this statement: Cells are the basic units of structure and function in organisms.
10/20 - What would happen to San Francisco if the power stations stopped working? What would happen to a cell if all of its mitochondria stopped working?

12/9 - In fruit flies, the allele for red eyes (R) is dominant and the allele for white eyes (r) is recessive. If a red-eyed fly and white-eyed fly have only red-eyed babies, what is most likely to be the genotype of the red-eyed parent: RR, Rr, or rr?

8/17 - Turn to page 13 in the textbook and complete the 'Standards Warm Up' activity. Make your own observation and Inference, then share your thoughts with the table group.
8/19 - Describe in detail the bathroom and drink procedures for science class.
8/22 - For the photo below, make a qualitative and quantitative observation. Then make an inference.

8/24 - Use the data table below to make an appropriate graph. Graph the averages.
8/25 - Write a hypothesis for the experiment below.
If __________________, then _________________.
I think this because__________________________.
9/1 - Write a scientific question for the procedure below.
9/7 - What are the similarities and differences between an inference and a hypothesis?
9/8 - Write the procedure for an experiment using the following question:
How does walking up a flight of stairs affect your heart rate?
9/15 - How do people use examples from nature to design technology?
(Example: Velcro was inspired by burrs (seeds) from plants that stick to animals in order the spread the seed)
9/16 - (Just answer this Warm Up, Do Not Copy)
Scientist Jared is testing some brands of batteries to see which one lasts longer. He uses AAA Energizer batteries for a flashlight, and AAA Duracell batteries in a digital camera. He leaves them both on for 24 hours, then measures how much charge each battery has left. Scientist Jared concludes that Energizer batteries last longer, because they have more charge left. Do you agree with him? Why or why not? Is there anything you would change about this experiment?
