3 October–Return Reports, Data on bottle experiments, STP conference prep, conservation of mass videos

Find the mass of the following bottles.

  • Vinegar and steel wool.
  • Steel wool and moist air.
  • Moistened paper towel and mung beans.

Enter data on the class spreadsheet. You need two “after masses” for the vinegar and steel wool; steel wool and air; and mung beans. Will mark data collection as formative assessment.


Do not open the bottles. Record any observations of the bottles themselves and the contents. Think about what might be happening.

If you did not set up the experiment, do so. You may need to restart an experiment. If the paper towel looks dry and your beans have not sprouted, set this experiment up again. You need enough water–but not too much.


Open powerschool and read the comments on your Mixing Ethanol and Water Report. You now have 2 weeks if you want to resubmit. In order to resubmit, you should read the comments and compare to your self-assessment. Ask any questions you have. Revise according to the comments. Resubmit with a copy of the comments, the original paper, and the revised paper, and a new self-assessment that considers the first self-assessment and what you have done in the revision. All of these documents should also be loaded properly in the digital science notebook. Due in two weeks if you want to resubmit.

Prepare for Student Teacher Parent conferences:

  • Create a document to hold links to various artifacts. Do not create a presentation or create a script. We only want you to have quick access.
  • Have your digital science notebook up-to-date.
  • Describe what you have found the most interesting so far this year.
  • Have examples picked out (linked) from your digital science notebook.
  • Pick out the most complete entry.
  • Pick out the entry where you feel you learned the most.
  • Pick out the entry where you were surprised, puzzled, or uncertain.
  • Have these three entries available for quick access (save the links an put them in a Student-Parent-Teacher document).
  • Pick out your most thoughtful blog post and have the link ready for easy access.
  • Be prepared to explain why you think it is most thoughtful.
  • Have your ethanol and water available with a link.
  • Have a copy of your self-assessment ready.
  • Have a copy of the power school comments ready.
  • Be prepared to discuss your revisions.
  • Your chart of observations of matter–linking evidence–behavior and structure of atoms and molecules (see: http://rfrazier.msblogs.aes.ac.in/2016/09/01/3246/ and http://rfrazier.msblogs.aes.ac.in/2016/08/28/29-august-science-8/
  • What have been the greatest challenges.
  • Why do you think they are challenging?
  • Be prepared to share a plan for how you hope to work in science for the rest of the year.
