First Semester 6th Grade Exam Review Exam Schedule:
Tuesday, Dec. 18th -4th Period
Wednesday, Dec 19th - 2nd & 7th Periods
Thursday, Dec. 20th - 3rd and 6thPeriods
Friday, Dec. 21th -1st and 5th Periods
Test will be multiple choice/matching covering topics studied during the first semester.
Study Power Points and review games can be found in the documents section on the CRJH 6th grade
science web page.
Students should review previous review sheets/tests for study. Past tests/review sheets can be
located in student’s yellow binder in the returned test section or online in our Documents section.
Review lab safety rules and equipment
Scientific Method
Measure length using metric measurement (cm,mm)
Reading a graduated cylinder (mL) and triple beam balance (g)
Variables: Independent (change), Dependent (measure), and Constant (same)
The difference between mass and weight
Reading Graphs and Charts
Define volume
The formula for volume: V=LxWxH
Two ways to find volume: LxWxH and displacement (finding volume of an irregular shaped
object)
The density of water=1g/cm3 (Sink or Float)
Calculate density using formula D=Mass/volume
Read graphs/charts
Identify properties of Metals, Metalloids, and Non-metals
Define element
The periodic table- locate element’s name and symbol (first letter always capitalized)
Identify elements in a chemical formula
Understand the difference between an element and a compound
Identify chemical and physical properties
Identify chemical and physical changes
Potential and Kinetic Energy: Definitions and identify examples Energy transformations example: a flashlight = chemical electrical radiant In every energy conversion, some energy is always converted into thermal energy The Law of Conservation of Energy Kinetic energy depends on speed and mass Define and identify examples of Convection, Conduction, and Radiation Energy Resources: Geothermal, Solar, Hydropower, Coal, Wind, Petroleum, Natural Gas, Biomass, and
Nuclear

Explain the technique to properly read this piece of equipment:
Lab Safety & Equipment:
1. The appropriate technique to smell anything in the lab is wafting. Explain the technique of wafting:
2. Identify 5 lab rules that must be followed in the experimental procedure below:
The students were trying to determine if a chemical reaction had taken place.
1. Measure 20 mL of H2O into graduated
cylinder.
2. Find and record the initial temperature
of the water in oC by placing the bag with
H2O on the bulb of the thermometer.
4. Seal plastic bag containing the H2O,
leaving a small opening to place the
sodium bicarbonate.
3. Measure and pour 2 teaspoons of
sodium bicarbonate (NaHCO3) into plastic
bag and seal quickly.
4. Set plastic bag on thermometer and record
temperature in oC every minute for 5 minutes
on the data table listed below.
6. When the 5 minutes have passed, repeat
this procedure with 2 teaspoonfuls of calcium
chloride (CaCl2) and 20 mL of H2O.
7. Complete steps 1-4 using 1 teaspoon of
sodium bicarbonate (NaHCO3) and 1 teaspoon
of calcium chloride (CaCl2)..
