Does anyone have one?
I was thinking about using this website if something isn't already made up.
Dairy Farmers - Dairy Farming Today
Also what dairy labs do you do, which one is the most economical?
I just got done with a dairy lesson with my students. For notes we did a flip book that had the following tabs: breeds, anatomy, improvements, products, and vocabulary. This flip book followed a powerpoint that i will add to this. For products I had the kids make cinnomon butter. it only cost like 12 per 10 jars. all you need is small mason jars, marbles, heavy whipping cream, and any spices you need. I had them shake the jars and as they did i told them about what butter was and other products milk makes. You could even have them watch a video of how its things are made. (its a little noisy so i just had a discussion) or even a discussion of how many jobs one gallon of milk supply. So as they shook their jar we would stop and look at the transformation. When the butter was done I had bread for them to try it with. The jar of butter they could take home to their parents or take to their favorite teacher. They loved the lab and it was a lot of fun.
here is the powerpoint
I've done a lab similar to the one Renee talked about, but instead of mason jars I just asked all the students to bring in their own clean water/pop bottle to use. Even cheaper It was a small class so I just cut the top off each of their bottles when the butter was ready. We used the attached Butter Lab sheet that I got from another teacher. Good luck!
Do I have to use round marbles, or would those flat ones for decorating work?
Either should work, its just so you are knocking the fat around so it wants to cling together......you can always do smaller batches with out flavor, I have done that before and use film cansters with nothing in them. Its fun doing that because you can hear the liquid, then you hear nothing, and then MAGIC! the butter thumps around.........
How much cream do you need per student for it to be effective?
I wouldnt do very much- keep in mind the more you use, the more you have to shake it. My kids complained with just using the film canisters filled 1/3 of the way full........hope that helps!
Yes it helps a lot!
Here is a lab I do in Ag Biology for pH.
I took the attached lab (science of ice cream) which I think I got on COP somewhere and turned it into the Science of Dairy Processing Lab. I would recommend doing the first part of the lab where you melt different brands of ice cream to show the relationship between air injection and price of ice cream. The second part I have not had much success with, specifically because we lack good thermometers. The third part is just a twist on making ice cream in a bag. I am also attaching the notes I lecture from prior to starting the lab. Good Luck!
