Theres a hair in my dirt!!!
Today I learned that I should leave animals alone and in their natural habitat. If you change something in the environment it will effect other things. I also learned that worms are decomposers (because I didn't know that) and that Harriet is dumb. We need to be aware of our surroundings and not mess anything up! -
Abiotic and Biotic
Today I learned what abiotic and biotic mean, and what the difference is between them! Abiotic is something living or that was living, and Biotic is something that is not living and never was such as air, rocks, metal, etc. A few things that are classified in the Abiotic section would be, a person, hair, wood, trees, etc! -

Physical Properties 1
Today I learned how to classify. Me and my group classified things into these two groups: Symetrical and Non Symetrical and Toys and Tools! -
Physical/Chemical properties
I'm not quite sure what chemical properties my book has, but I'm pretty sure it on water. . . but I don't know what thats called! -
Physical/Chemical properties
Wind is a Chemical Property of air. (or atleast I think) -
Chemical/Physical properties
How can you tell what chemical properties a substance has????? they can only be observed during a chemical reaction!!!!! -
phase change!
3 things i know about Physical Changes:
It does not form a new substance
It always stays the same substance!
If ice cream melts, it is still the same substance! -

Atomic Structure
What is a rule for making a positive ion? You have to have more protons than electrons because protons are positive and electrons are negative. -
isotopes and ions
what particle determines an ioin?A proton because when you add one, it imballances the atom. What one determines an Isotope? A Neutron determines an Isotope because it doesn't effect the element but it does effect the mass. -
Periodic Table
the rows stand for the period that the element classifies in.
