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.
- correct the remaining fractions to divide, now that you have a better understanding
- continue working on area of irregular shape following strategy
