Today ISN Check 06 was officially assigned (the requirements for this ISN Check were written on the board in the classroom since Wednesday, 1/24/18).
We went over the ISN Check requirements line-by-line and discussed the expectations for completion.
Students had AT LEAST 30 minutes to work on any incomplete assignments for ISN Check 06. While students worked on ISN Check 06 Clean-Up, I passed back QUIZ #3 and QUIZ #4 and conferenced with individual students.
Today students collected the overnight (24 hour) data from LAB #9. They worked in their extended groups and completed all four data tables (1st Attempt Light Data and Dark Data, and 2nd Attempt "My Group" and "Sister Group").
We then began answering the 5 Lab Questions on the LAB #9 worksheet. Students have already been verbally assessed several times during the lab experience so I will post the answers here (by Sunday- hopefully sooner - NOW POSTED as of 1/28/18 at 12:13 PM) so that they may double check their answers on the lab worksheet.
Homework will be to answer their reflection questions and to make sure all parts of their lab are complete.
Today students were given the opportunity to redo Lab #9 using their revised procedures.
Students (if on-task and working effectively in their groups) should have been able to get their lab set-up in 15 minutes or less. This left students with at least 30 minutes of class time to work on completing the classwork that will be due with ISN Check 06 on Wednesday 1/24/18.
Today the students debriefed about their lab experience yesterday. We discussed our results (data), watched some video examples of similar labs, discussed our possible sources of error, and then worked in our (extended) small groups to decide upon at least three procedural changes to be made for our second run of this lab scheduled for tomorrow.
Here are the video links:
Today students performed LAB #9: The Carbon Cycle. This is a difficult lab to actually do correctly in our very short 48 minute periods. The students really did a fantastic job even though we did not get fantastic data. Tomorrow we will debrief and discuss what happened and what our possible sources of error were. I will give them the option of changing some of their procedures and redoing the entire lab on Thursday in hopes that we can get it set-up much more efficiently and collect better data.
Unfortunately, I erased our board today before I took a picture!
Learning Target: I will investigate the color changing properties of Bromothymol Blue (BTB) to help me design my procedures for LAB #9.
HW: Make sure Pre-Lab #9 Cornell Notes are COMPLETE!
Today I performed a demonstration of the color changing properties of BTB in the presence of Carbon Dioxide and in the absence of Carbon Dioxide. The students then worked in pairs to replicate this demo. The goal for students today was to understand how to use the BTB (and the other lab supplies we practiced with today) and why we use the BTB. This understanding will then help them design a lab to test their assigned scientific question.
I will be out tomorrow due to a mandatory all-day conference (YAWN!) that I must attend. Students will work in their groups to write down detailed lab procedures for their specific LAB #9 scientific question. While we discussed these procedures as a whole group today, I expect that this will be a difficult task but believe that the students are up to the challenge and am excited to see what they come up with when I return on Monday.
Today students were given their Individual Student Report which lists their grade for each assignment for Trimester 2 so far. Students copied down instructions into their ISN on how to submit any remaining latework. We discussed every assignment and how to submit late assignments for grading consideration.
Students were told today that I WILL NOT take latework at this point if they do not get their ISR signed by their grown-up. This is imperative because parents/guardians need to be aware to what extent their student is not doing the work required.
As discussed in my Classroom Policies, I take latework at full credit as a courtesy to my students and their families which I provide to them out of respect for the sometimes chaotic modern lives we lead. This privilege should not be abused. Latework should be the exception for your student, not the rule.
After this, students had 15 minutes of class time to either continue working on their latework or completing the Pre-Lab #9 (which should have been completed yesterday in class). There will be a QUIZ tomorrow on the articles for Pre-Lab #9.
