[ccp4bb] Demonstration for 2nd graders?
Hi everyone, Slightly off topic here but I got myself volunteered by my 2nd grade son to do a show and tell at his class. I have the rock candy experiment ready with some background info on what I do. Can anyone direct me to some resources or your personal demo's that you have done? Thanks a bunch -John

This one is probably above second grade, but the equipment setup is pretty easy http://ipl.physics.harvard.edu/wp-uploads/2013/03/15c_s07_5.pdf Measuring the wavelength of light with a ruler On 01/08/15 13:35, John Lee wrote: Hi everyone, Slightly off topic here but I got myself volunteered by my 2nd grade son to do a show and tell at his class.

Re: [ccp4bb] Demonstration for 2nd graders?
When my daughter was in Kindergarten, her class took a trip to our facility, and I showed them some of my crystal trays (What do you see here? Do you see anything? Clear drops ..., they effectively said). Then I showed them through the microscope several crystals, and I was pleasantly surprised by their awe (oooh! Jewels!). Then I showed them some loops by-eye and by-microscope. I'd have liked to show them how I manipulate a crystal with that loop, but I wasn't set up to project it for everyone to see real-time. I then told them about protein machines that line up in a particular way to form that jewel they'd just seen. ...I imagine you cannot bring a good enough microscope into the classroom with you without some hassle, but I thought I'd share at least that 5-6 year olds, even, can find protein crystals very fascinating.

I like the sodium acetate crystallization from Dr. Shakhashiri’s Chemical Demonstrations. I prepare the supersaturated solution ahead of time, then seed it with crystals during class. It’s fast, simple, entertaining, and the flask gets warm, showing that heat is being released by the reaction. Here’s the link: http://lecturedemos.chem.umass.edu/solutions13_3.html.

Re: [ccp4bb] Demonstration for 2nd graders?
I have had young ones grow lysozyme crystals in just a few minutes, using eye droppers and petri dishes. The crystals grow very fast, you can watch them grow in the microscope. Also they grow large enough you can see them by eye. Some izit dye would be fun to add (never did that). Then I let them take the setups home with them (nothing toxic in it). They all wanted to take them home. Stock solutions: 100 mg/ml sigma lysozyme in 50 mM sodium Acetate pH 4.5 4 M stock NaCl 50% w/v MPEG 5,000 1 M stock sodium acetate pH 4.5 Reservoir MasterMix for 60 reactions 9 mL water 22.5 mL NaCl 4.5 mL sodium acetate 54 mL MPEG with transfer pipette into small 35X10 mm Petri dish 1 drop protein + 1 drop reservoir Mix equal amount of lysozyme with reagent. Dilute protein and/or MPEG and/or Sodium Chloride for less nucleation, larger, and better shaped crystals.
