Slide 1

´╗┐fifth Grade Science Mrs. LaRosa Matter Study Guide www.middleschoolscience.com 2008

Slide 2

Matter Anything that has a mass and a volume

Slide 3

States of Matter Solid Liquid Gas Plasma Close up perspective of iotas and their conduct Animated pictures are from http://www.chem.purdue.edu/gchelp/

Slide 4

Physical versus Concoction Change Changing starting with one state then onto the next is a Physical Change. In the event that another substance is framed it is a Chemical Change. Pictures are from http://www.chem4kids.com

Slide 5

Atoms The building squares of Matter Consists of Protons (+), Electrons (- ), and Neutrons (N). Components Consists of stand out sort of iota , Cannot be separated into a less complex kind of matter by either physical or synthetic means Can exist as either iotas or particles . Pictures are from http://www.chem4kids.com

Slide 6

Molecules A particle comprises of at least two iotas of a similar component, or distinctive components, that are artificially bound together. In the movement above, two nitrogen iotas (N + N = N2) make one Nitrogen atom .

Slide 7

Compounds Atoms of at least two unique components bound together . Can be isolated into components artificially , but not physically. In the movement above, water (H 2 0) is a compound made of Hydrogen and Oxygen . Enlivened pictures and notes from http://www.chem.purdue.edu/gchelp/particles/elements.html

Slide 8

Solutions are gatherings of atoms that are stirred up in a totally even appropriation. Homogeneous Uniform Distribution. Case: Sugar and Water Images are from http://www.chem4kids.com

Slide 9

Solute The substance to be broken up. Dissolvable The one doing the dissolving. Pictures are from http://www.chem4kids.com

Slide 10

Making a Solution

Slide 11

Colloids Particle sizes are in the middle of the extent of particles found in arrangements and suspensions . Can be blended and remain uniformly appropriated without settling out.

Slide 12

Mixtures They are substances held together by physical strengths , not synthetic. Can be isolated physically. Arrangements are likewise blends. Heterogeneous The substances are not consistently blended. Illustration: Sand in a glass of water. Pictures are from http://www.chem4kids.com

Slide 13

Mixtures Suspensions Are heterogeneous blends comprising of parts that are unmistakable to the exposed eye. Substances will settle after some time . Illustration: the fixings in plate of mixed greens dressing

Slide 15
