the level in the carboy when you are doing your readiness checks. If it looks like it’s getting low, let us know so we can replace it. If the students need to re-smash their candies, they can do so by gently tapping the candy with an iron ring while the candy

item sticker on the faulty unit. <b>When doing cart checks for this experiment, swap the entire bin of reagents regardless of fill level. Do not check individual bottles- it takes too long.</b></span><span style="font-size:11.0pt;font-family:"Buckeye Sans 2""><o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Buckeye Sans 2";color:#212121">There will be some rooms with a mix of old (black wire) and new (white wire) probes, and some rooms with only new (white wire) probes. The probes with the black wires
will need to be attached to the top of the meters whereas the new probes will need to be attached to the white cables that are already on the meters.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Buckeye Sans 2";color:#212121">The new probes will easily screw onto the cable (the other end is already connected to the meter), but the students may have issues with connecting the old cables
to the meters. The black wires are attached to the top of the meter by pushing and turning. Both pH probes will have either a black
<span class="spelle">o-ring</span> (old) or a blue rubber o-ring (new) at the top of the probe to cushion it from the glass storage tube and help seal in the storage solution. These can stay at the top of the probes while the students are taking readings. The
students should only remove the probe from the storage rack, not the tube. Students should replace the probe into a test tube filled with storage solution when done. Probe tips should not be allowed to dry out.</span><span style="font-size:11.0pt;font-family:"Buckeye Sans 2""><o:p></o:p></span></p>

be placed in the labeled bin so that one of the prep lab staff can check them and make any necessary repairs. If a student has a broken old probe, they will need to pick up a cable with the new replacement probe.
