Physical and Chemical Change

Changes everywhere!!

Physical Change- change to matter in which no new kind of matter is formed

• Examples:
• Origami (art of folding paper)
• Cutting Paper
• Ice Melting

• Mixture- a substance that  contains two or more different types of matter
• These types of matter CAN BE SEPARATED!! That is very important!
• Examples:
• Alphabet Soup
• Trail Mix
• Marbles and Beads in a bag
• Solution- a mixture in which the particles of the different kinds of matter mix together evenly.
• This is different from a regular mixture because you CANNOT SEPARATE the different kinds of matter BY HAND!!
• Examples:
• Salt Water
• Sweet Tea
• A Penny (this is a solution of two metals called an alloy. A penny is made of zinc and copper)

Chemical Change- change that forms a different kind of matter

• Examples:
• Cooking Food
• Rusting Nails
• Burning Wood
• What are some ways we use chemical changes in our lives?
• Burn fuel to power our cars.
• Cook food so we can eat it.
• Digestion
• FUN FACT: Plants use chemical changes to make their food!

Perimeter of Regular and Irregular Shapes

Perimeter---the distance around  a figure

Regular shapes-- squares, rectangle, triangles

Irregular Shapes--any shape that does not have equal sides

To find the Perimeter of shapes that provides side lengths...ADD ALL THE SIDE LENGTHS.

4 + 5 + 8 + 3=  20                The perimeter of the shape is 20 inches.



To find the Perimeter of a shape that does not provide side lengths, but does provide units...COUNT THE UNIT SEGMENTS.

UNIT SEGMENTS---THE OUTSIDE OF EACH UNIT

Area and Distributive Property

Area-  The surface of a shape or the region of a shape.

Distributive Property--Break up the larger factor/number

Light Report Confusion!

There has been some confusion about the light report.

This is an in class assignment that does not need to be worked on or completed at home. We are working on the students' informative writing abilities to better prepare them for the writing test. Due to this we are not accepting "Final Drafts" from home. 

We will be meeting with each student to read and edit their rough draft in order to explain the writing process and correct any misunderstandings they may have about how to write the report. 

Thank you and sorry for any confusion! If there is ever any project or assignment to be completed at home, information will be included in the newsletter.

Have a wonderful evening!

-Ms. Mason

Light

There are no real notes for light this week because the students are watching light videos and taking notes on the information provided. The students are sharing their information by interviewing each other, and using these facts to complete a 5 paragraph report on light for their test.

The videos are The Magic School Bus Gets a Bright Idea which can be found on Netflix, and Science Video for Kids: How Does Light Travel? which can be found on YouTube. I will also post the link to the second video on the fun videos and websites page.
