Transcript of Mr. Smet’s Scientific Studies March 17 th, 2011 CONSERVATION OF MATTER.
1. Place your homework on the table in front of you:
2. Complete the following on a loose-leaf sheet of paper:
1. Define matter.2. Define energy3. When heat is added to matter, what happens to the
temperature, speed of particles, and distance between particles.
4. When heat is removed from matter, what happens to the temperature, speed of particles, and distance between particles?
DO NOW
Objectives:SWBAT defi ne matter.SWBAT defi ne and recognize states of matter.SWBAT defi ne and recognize phase changes.SWBAT explain phases by the speed and position of
atoms or molecules.SWBAT draw molecular or atomic representations of
the phases of a substance.SWBAT defi ne energy.
SWBAT explain and diagram the outcome of adding energy to a substance.
REVIEW
For the following review, there will be 15 questions ton the Smart Board.
Your task will be to write down the answers to these questions onto a sheet of paper and be ready to share out when discussing the answer.
REVIEW
MEASUREMENT TOOLS
1. Name: Triple Beam Balance Measurement: Determine the mass of a
substance Units: grams (g)
*IMPORTANT REMINDER!
A triple beam balance has three separate lines (it’s like adding three rulers together)-you must ADD each of the lines together!
Step #1: Make sure all riders are placed at zero (on the
far left). The white line on the black arm should be level with the zero mark on the right side of the balance.
Step #2:Move the rider on the middle beam (largest
mass) to the right to the last notch before the arms dips down. When the white line on the arm dips below the zero mark, move the rider back one notch to the left.
STEPS 1+2
Step #3:Move to the next-largest rider (back beam) to
the right. Move it to the last notch before the arm dips down. When the white line on the arm dips below the zero mark, move the rider back one notch to the left.
Step #4:Slide the smallest rider (front beam) to the
right. Slide it until the white line on the arm dips below the zero mark. When the white line on the arm dips below the zero mark, slide the rider back to the left.
STEPS 3+4
