solvent • The part of a solution that is in the greatest amount, and is usually a liquid http://ellencarrlee.files.wordpress.com/2010/08/solvent-storage-in-flammables-cabinet.jpg
mixture • Two or more substances which are combined, but can be taken apart again easily aphschem.blogspot.com
solute • The part of a solution that is the lesser amount, and is usually a solid http://www.infoplease.com/images/cig/science-fair-projects/09fig01.png www.chem4kids.com
concentration • The amount of solute in a solvent determines this; the amount of material dissolved in a measure of liquid http://www.bbc.co.uk/bitesize/standard/chemistry/images/copper_sulphate_solutions.gif
chemical change or chemical reaction • Occurs when two or more substances are combined and create a new substance that cannot easily return to its original form http://www.chem4kids.com/files/react_intro.html (Just imagine how hard it would be to break water back down into hydrogen and oxygen!!)
solution • A type of mixture which has one substance dissolved in another http://www.weironline.net/chemcentral/labs/solutionstoichiometry.jpg
evaporation • Causes liquid to dry up – the liquid turns to gas and disperses in the air, leaving any dissolved material behind jxluvscience.blogspot.com www.uen.org
crystal • The solid form of a material that can be identified by its properties, such as shape, color, and pattern http://www.tumblr.com/tagged/salt%20crystals
property • A characteristic of an object; something you can observe such as size, color, shape, or texture http://www.setbc.org/curriculumset/resources/properties_of_matter/properties_of_matter.gif
dilute • To make a solution less concentrated, usually by adding more liquid http://biology.kenyon.edu/courses/biol09/tetrahymena/serial%20dilution.jpg
dissolving • A process in which one material disperses uniformly into another material, so that the first material seems to disappear pharmaceutical-technology.com
solubility • The property that substances have of dissolving in solvents; ability to dissolve www.ehow.com
saturated solution • When a solute has dissolved in a solvent until no more will dissolve http://water.me.vccs.edu/courses/env211/changes/saltsolution.jpg
precipitate • A solid material that forms as a product of a reaction dartmouth.edu chemistry.about.com
filter • a porous article or mass (as of paper or sand) through which a gas or liquid is passed to separate out matter in suspension (www.m-w.com) en.wikipedia.org walgreens.com mooremechanical.com
filtration • The act of changing a fluid by passing it through a filter synderfiltration.com
volume • The three-dimensional space occupied by something mathsisfun.com grc.nasa.gov
reactants • The chemicals that are changed when they are mixed in a chemical reaction sciencequiz.net chem4kids.com
thefreedictionary.com flotation • a process for separation of mixtures, used when one substance floats to the top of another year7hawkesdale.wikispaces.com goldorecrusher.com
sifting • separating materials through a type of screen or sieve bloatalrecall.blogspot.com
magnetic attraction • Force that causes a material with iron to move towards a magnet italiangirlingeorgia.blogspot.com
chromatography • A technique for separating mixtures; as the mixture flows across a surface, different parts separate and can be seen ljcreate.com
hypothesis/prediction: • You might hypothesize that an increase in mass increases downhill speed based on your experiences riding bikes with your friends. Hypotheses are often stated including both the manipulated and responding variables. • A statement about what you think the results of an experiment will be. This should be based on prior knowledge, not a wild guess.
Variables: • The manipulated variable is the thing you change to see what happens. This is also called the independent variable. It is graphed on the x-axis. *The weight on the bike.* • The responding variable is the thing that might change because of what you did. This is also called the dependent variable. It is graphed on the y-axis. *The speed at which the bike goes down the hill.* • The controlled variables are the things that you need to keep the same. *The bike.*
