1) explain, what technology are you using to complete this assignment, how does it work?
2) observe the view outside your window, ask the question about something you have seen (clouds, trees, buildings, moving vehicle etc.)
3) formulate hypothesis about object/fact you observed;
example: when I look at the cloud it changes its shape, because... (predict why)
4) list five (5) facts about your observation, using your five senses (see, smell, taste, touch/feel, hear), list constant or variable facts;
example: I see white clouds, clouds are wet (fog is a cloud), the rain falls from clouds, the air, after rain, smells fresh, some clouds make a
thundering sound, etc.
5) look around your room or your house; can you see a model? describe it.

Imagine you are a student in alfred hershey and martha chase's lab in the late 1940's. you are given five test tubes with the e. coli bacteria that were infected with t2 bacteriophage that have been labeled with 32p or 35s. unfortunately, you forgot to label the tubes and are now uncertain which were 32p labeled and which were 35s labeled. you place the contents of each tube in a blender and pulse it for a few seconds to shear off the protein coats from the bacterial outer membranes. you then centrifuge the contents to seperate the protein coats and the bacterial cells. you then check for radioactivity and obtain the results shown below. which tubes contained e. coli infected with the phage labeled with 32p? select all tubes that apply.
