Gummi Bears....Oh my!

We started an experiment today to see how soaking gummi bears in water and alcohol will affect their density.  In order to know the density we had to measure the volume and mass.  On Monday we will see how each measurement has changed to affect the density of the gummi bears.

STAY TUNED!!!


We also made some mini posters to ensure we knew the difference between biotic and abiotic factors.

BIOTIC

This category includes all living organisms.....even if that organism is now dead.

ABIOTIC

It doesn't mean DEAD.  If something is dead, it was at one time alive and therefore biotic.  These are the factors that were never living.

Could you list examples of each????

Post some pictures in the comment section to let me know you are 100% sure of the difference.

See you Monday!
