Sept.16

Today we are beginning to conduct our first experiment.  We will repeat the experiment to ensure our results are indeed accurate.  We will follow the scientific method as outlined below.  We will explain what we observe happening using the particle theory of matter chart text pg.12   Each team will submit 1 lab write-up by Friday Sept.19th handwritten or typed (saved to flash to print).

Science Lab 1: Particle Theory of Matter

Purpose:  In this experiment we will dissolve sugar crystals in water, make observations and explain our observations using the particle theory of matter.

Hypothesis (before conducting experiment):

If we dissolve sugar in water at room temperature, then we think… (what do you think will happen & why?)

If we dissolve sugar in cold water, then we think…

If we dissolve sugar in hot water, then we think…

If we dissolve sugar in room temperature water, then we think...

Procedure:  follow step-by-step instructions on pg.13 “Try This” box #1-4.

Observations: (you can create a table in MS Word click insert table, 3 columns, 4 rows, auto fit to contents and type)
