5 Things I Learned About Preparing Bones For Display

So, I thought it would be a good idea to prep a duck head and feet set to display the bones.  Sounds like a good idea, right?  You can make comparative anatomy displays for the classroom.  Fabulous!

I started with this:

duck head and feet set from Dissection Connection
Duck Head and Feet Set

Threw the lot into a pot and simmered it for about two days. It didn’t smell as bad as I thought it would. Kind of like soup.

5 things I learned about preparing bones for display:

  1. THIS KID is awesome
  2. Take as much of the skin, muscle and viscera off the bones as you can BEFORE you start.  Now I have spent at least an hour picking bits of meat and skin off tiny bones and checking meticulously that I haven’t missed anything.
  3. Put the separate pieces into SOMETHING before you start.  Bags made of old pantyhose would have done the trick.  Now I have no idea which bones belong to the left foot and which to the right foot.
  4. Cleaning bones and laying them out on a tray made me feel just like Temperance “BONES” Brennan – even though I had no idea what I was looking at most of the time.
  5. It was a VERY good idea not to throw the chicken head and feet into the pot at the same time!

As this kid laments, there is next to no info on the web about articulating bird skeletons.  I will definitely post a picture of the finished product with some more tips and tricks for you because you are going to be hard pressed to find it elsewhere.  Stay tuned, Vivsters.

Top Tip: How to use live semen with digital microscopes and SmartBoards

This Top Tip comes from Tamara Daus, Science Operations Officer at Kingston State High School, in August 2013.  Thank you, Tamara!  This is a specimen we don’t see enough of in schools and the collective wisdom of lab techs is the best source of info for others to learn from.

Semen from Dissection Connection, new digital microscope… Movies worked really well too

I’m taking the semen into the first Year 8 classes tomorrow. We’ll be able to have the digital microscope up the front with the image on the SmartBoard for the whole class to see, and then the groups will be able to use their own microscopes to focus and check out their own slides.

Thanks Miss Vivi J

Got a Top Tip you are willing to share with other techs? Have a squeal to Miss Vivi and see your name in lights.

Top Tip: How to defrost brains for dissection in 1 hour

sheep brain for dissection

This Top Tip comes from Patricia Hugman, Senior Laboratory Technician at St Joseph’s College Toowoomba.  Thank you, Patricia!  This is something we get asked all the time and the collective wisdom of lab techs is the best source of info.

sheep brain for dissection mmmm...... brains!

Have you ever wondered how long it would take to defrost … brains for dissection?

I found the following method for defrosting brains to be very effective & efficient

To defrost brains ‘al dente’ in 1hr

1.       Straight from freezer

2.       Place brains in packet in suitable container & cover with water (4 litre icecream container works well) sitting ‘flat’ not ‘end on’

1pkt/ container defrosts faster that 2 in one container

3.       @20min – Change water

4.       @40min – discard water, remove brains from packet, sprinkle liberally with salt, just cover with water

5.       @50min – gently separate brains, being careful of brainstem/medulla

6.       @60min – carefully remove individual brains, pat dry with paper towel and ‘serve’ to students!

On a nice summer’s day (25deg C) this timing worked a treat. Producing brains that were still firm but not icy.

Sitting on the bench (in air) produced irregular defrosting >4hr
