Science Lab write-up #1 Text pg.12-13
Context
·        Matter is anything that has mass and takes up space.
·        The study of matter and its changes is called chemistry.
·        Chemists often study matter in nature and imitate it i.e. artificial flavors, colors, fragrances, synthetic fabrics.
·        Through powerful microscopes, chemists can see that all matter is made up of tiny particles that are always moving, that attract each other and have space between them.
Purpose
We will conduct an experiment dissolving sugar in water at different rates to explain what we observe using the Particle Theory of Matter.
Hypothesis
1.  If we stir a spoonful of sugar in a ceramic coffee mug filled with water at room temperature (20˚C), then we think it will take 3-5 minutes to dissolve because it’s not too hot and not too cold causing the sugar particles to dissolve at a medium rate.
2.  If we stir a spoonful of sugar in a ceramic coffee mug filled with ice water (4˚C), then we think it will take 15-20 minutes to dissolve because the sugar particles are barely moving and attracted close to each other when cold.
3.  If we stir a spoonful of sugar in a ceramic coffee mug filled with hot water (85 ˚C), then we think it will take 30-60 seconds to dissolve because the sugar particles are moving quickly and spreading apart when heated.

bring in some materials to conduct lab.  I will bring in some and we will all share.
