Science Benchmark:  The weight of an object is always equal to the sum of its parts, regardless of how it is assembled. In a chemical reaction or physical change matter is neither created nor destroyed. When two or more materials are combined, either a chemical reaction or physical change may occur. Chemical reactions are often indicated when materials give off heat or cool as they take in heat, give off light, give off gas, or change colors. In a chemical reaction, materials are changed into new substances. In a physical change a new substance is not formed.
WEEK OF JANUARY 20-24
MONDAY- 
  • NO SCHOOL-Dr. Martin Luther King Jr. Day
TUESDAY-
  • SEE HISTORY

WEDNESDAY-​
  • VOLUME is the total amount of space that an object takes up.
  • In order to find VOLUME we have to find the LENGTH, WIDTH, HEIGHT of the solid and multiply those together to find the total volume. Use centimeters. We express total volume in cubic cm.
  • Students calculate VOLUME of box L x W x H. 

​THURSDAY-​
  • SEE HISTORY

FRIDAY-​ 
  • Students take objects and find mass and volume of each.
  • What if we wanted to find the VOLUME of a LIQUID? 
  • Students will measure the volume of liquids by using graduated cylinder that arks the level of the liquid. We express VOLUME of liquids in mL.
  • What about irregular solids? Do irregular objects have a volume? If so, how can we measure it? What is an "irregular" object? (1 cubic cm = 1 mL)
  • Measuring DENSITY (another physical property of matter) in solids, irregular solids, and liquids. DENSITY is the comparison of the amount of the space taken up-how TIGHTLY the MATTER is packed into a certain object.
  • How can we calculate DENSITY? In order to calculate density, you have to know the mass and the volume of an object first.  D = M divided by V. The amount of density that an object has is always the same, no matter how large or small the volume of that object gets.​​
STANDARD 1: Students will understand that chemical and physical changes occur in matter. Describe that matter is neither created nor destroyed even though it may undergo change.
  • Evaluate evidence that indicates a physical change has occurred. Investigate evidence for changes in matter that occur during a chemical reaction.
