Science 7 - Chemistry Notes on Mass, Volume, Density

Study Notes for Chemistry Quiz on Mass, Volume and Density

The quiz will consist of short answer, true and false and some volume and density problems. 

Know these definitions:

Matter	Anything that has mass (not weight) and occupies space (volume)
Mass	A measure of the amount of matter in an object
Volume	A measure of the amount of space that is occupied by matter
Density	How close together the molecules of a substance are

Know the formula for calculating density:

Density = Mass                   Volume

Know the units for how to record the measurements for the following:

Mass	Milligrams (mg), grams (g) or kilograms (kg)
Volume	For liquids - Millilitres (mL), or Litres (L) For solids – cubic centimetres (cm3)
Density	For liquids – g/mL For solids – g/cm3

Know the 3 ways to calculate volume.

For a rectangular solid	Volume = length x width x height
For a liquid	In a graduated cylinder
For an irregular solid (weird shaped)	Displaced Water Method

You will be asked to calculate volume. Go to ixl.com, grade 7, O.36 (Volume) to practice.

You will be asked to calculate density.  Here is a place to practice some problems: Density Practice Problems  The first 2 problems are easy and will be similar to the ones on the quiz.  The problems definitely get harder as you go along and those kind WILL NOT be on the test, but then you like a challenge, right?

Weekly Challenge: I know it was really hard for some of you to ask for sponsors for the bowlathon, but the results were FANTASTIC!!  The school raised approximately $17,000 for our Financial Assistance Program.  This allows many families to be able to attend HCS even if they aren’t able to financially afford it.   This week, with the warmer weather, let’s try the water challenge again.  This means drinking 8 cups of water a day.  Be sure to track this every day, not just estimate. 

KCC  Relate Youth – Small groups this week.  Check with your leader to find out what’s going on.

Extra Math Help – From 3:00 to 4:00 every Wednesday in the Library.

 

Math – Please have all the ixl.com integer work completed by Thursday as we will be having an Integer Quiz on Thursday afternoon before electives.  (Gr. 7 D.1, D.2, D3, D.4, D.5, D.6 and E.1 and E.3)

 

 

Homework Sheet April 13th to April 17th

Grade 7 Homework Sheet

Monday, April 13^th - Friday, April 17^th

Announcements:

·         Be sure to get some sponsors for the Bowlathon coming up on this Friday, April 17^th.  I have been disappointed to hear rumblings of students who are thinking that this is optional.  It is NOT!  If you do not raise $20 in sponsorship for the bowlathon, there is still school for those left behind.  They will also need to bring a lunch as the Hot Dog Barbeque is only for those who have the $20 sponsorship.  If a student is unable to attend the bowlathon due to an appointment or acceptable excuse, then I would still encourage them to try and raise sponsorship for the school. The bottom line is that we are raising money to help support those MANY FAMILIES who require financial aid.  The objective of this fundraiser is NOT for students to ask their parents for money.  It is to earn the money or ask people outside our school community if they would like to support the school.  Many people are willing to do that.  Even if they choose public schooling, they support the belief that families should have the choice to send their children to a Christian School regardless of their finances. 

Weekly Challenge: How did the abstaining from some aspect of technology go last week? This week, the challenge is to ask at least one person outside of the school community to sponsor them.  (There are 3 days to do this – Tuesday, Wednesday, Thursday.  The challenge is to ask, not get a donation, so if you ask 3 different people on 3 different days, and get 3 “No thank you’s”, then you have still met the challenge.)

KCC  Relate Youth – Come on over to Mrs. Robideau’s house for yummy soup before Youth on Tuesday.  We will be doing the Bottle Run beforehand so bring your bottles in that day.  Thanks!  

Extra Math Help – From 3:00 to 4:00 every Wednesday in the Library.
