Students from 2nd and 3rd period were testing today and did not attend my class.
Students from 4th period did not participate in the lab today. Not a single student complete their Pre-Lab and Teacher Demo sections (class work from Tuesday and Wednesday). Students were given the entire period to complete this work so that they could participate in the hands-on activities of the lab tomorrow. This lab can be completed by watching videos on YouTube. The Videos and Links have been provided below.
Today students participated in four student-led experiments to help them solve our problem and explain our phenomenon.
WEDNESDAY 5/22/19 - I#21: PROPERTIES OF WATER TEACHER DEMONSTRATIONS AND ISN CHECK 12 OFFICIALLY ASSIGNED
Students from 2nd and 3rd period were testing this morning and did not attend my class.
Today students watched a video to familiarize themselves with Water Striders. We then introduced the phenomenon around which our investigation centered - Why are the Water Striders falling into the river?
I then demonstrated two simple experiments (the Toothpick Star and the Water and Oil experiments). Students were asked to document their observations by modeling. They were given links to Web research to help them make sense of the experiments, label their modeling, and pinpoint the property of water that they were observing in the experiments.
Students will be participating in several student-led experiments tomorrow to help them complete this lab.
Today students watched a short BrainPop! video about the properties of water. I asked them to complete a Pre-Lab for our properties of water lab scheduled for 5/22 - 5/24. This assignment was due by the end of the period.
Today students read about historical development/discovery of the concept of the Mole. We also practiced calculating Moles of molecules. Students were then asked to design an experiment that could answer the question, "Can a Mole of peas fit inside your home?"
friday 5/17/19 - ISN check 12 clean-up, creative outputs, and individual student conferences for late work submissionRead Now
FRIDAY 5/17/19 - ISN Check 12 clean-up, CREATIVE OUTPUTS, AND INDIVIDUAL STUDENT CONFERENCES FOR LATE WORK SUBMISSION
*****No Tutoring on Monday, 5/20/19 (due to a meeting at the DO) Make-up TBA*****
Today students were given the entire period to work on late work (and have it graded on the spot) as well as getting their ISN prepped for our last ISN Check of the year.
Students had access to the ChromeBooks to help them complete their work.
thursday 5/16/19 - i#20: investigating the mole (using water as an example to model how matter is organized and quantified by scientists)Read Now
THURSDAY 5/16/19 - I#20: INVESTIGATING THE MOLE (USING WATER AS AN EXAMPLE TO MODEL HOW MATTER IS ORGANIZED AND QUANTIFIED BY SCIENTISTS)
Today students participated in an easy investigation of the how matter is organized and quantified by scientists.
We began by taking guided notes that reviewed our previous learning about elements, the periodic table of elements, atoms, molecules, and modeling molecules. The guided notes were completed by having a whole group discussion while reviewing prior notes. I projected a copy of the notes and wrote down the answers with the students.
We then measured out 18 grams of water using the Triple Beam Balance and modeled our observations on lour lab worksheet.
Next, students watched a BrainPop! shot video (5 minutes) that introduced the concept of the Mole (Avogadro's Number) and how it is used to quantify matter.
After the video, we completed our notes about the Mole by writing out Avogadro's Number with all 21 ZEROES!
Students then had 5 minutes to write a 3 - 5 sentence answer to the Essential Question for the day, "How do Scientists organize and quantify matter?"
This Investigation was due at the end of the period.
Today students were guided through using the PhET Sim to create a final model of Acids, Bases and Neutrals, on the macro and molecular scale, for documentation in their ISN.
Students were asked to turn-in their completed model by the end of the period.
Today students completed their PhET SIM Investigation of Acids, Bases, and the pH/pOH Scale. Students were asked to submit their completed lab by the end of the period.
Today students were asked to complete I#18 by researching the actual pH of the substances they tested and then creating a final model. Students worked in their groups to research and complete the final two columns of their data tables, their final models, and the to answer the three reflection questions. This lab was to be completed by the end of the period and turned-in.
