No, just sitting in a lower chair than usual. My injured hip was acting up, so I needed a different chair.
plz answer my question
so are bones the only thing that you can do this with?if not what are the other objects you can use?and was that vinegr or water?
Bones are the only thing that
Bones are the only thing that will give these results, and some bones work better than others. For the best results, use thin bones. It might be interesting to try bones from different animals. I suspect that fish bones would work very well.
Does the bone have to be cooked?
Does it matter if the bone is cooked or raw? We tried this last year with water as a control but then I was too scared to open the containers and "test" the bones. Ick.
collagen
is it possible to put collagen into a seashell?
No. Because the sea shell is
No. Because the sea shell is not a living part of the creature, collagen could not grow in it. The collagen requires nutrients to grow. In our bones, those nutrients are carried by blood that flows through blood vessels in the bone.
question
would a small seashell get squishiy if you soak it in vinegar?
No. Because the seashell
No. Because the seashell does not contain collagen, once the calcium carbonate dissolved away, nothing would be left behind. It would just dissolve away.
interesting
who new ??????

Bendable Bones
Love this experiment. This should help the students understand that bones are not dead! :)
