Science

On Friday we gathered data to graph the temperature during a change of state. Unfortunately, the ice was too cold, it took a long time to melt. The warm water wasn't warm enough to melt the ice! On Monday, we will still graph our data using a BROKEN LINE GRAPH. The last topic in this unit is chemical changes. We will see how much we can get done.... it's a busy but very exciting week!

What is the difference between a physical and chemical change? In a physical change, the type of matter (molecules that make up matter) are the same. They may be further apart or closer together, but they are still the same molecules. In a chemical change, the atoms rearrange to form new molecules and the change is IRREVERSIBLE. These are signs of chemical changes:

We will begin Data Management this week. We have already constructed and drawn conclusions from many tables and graphs in Social Studies and Science. It will be a fairly short unit, with most of the graphs and surveying done at school.

Continue to practice your times table. You will be given SHORT quizzes on your division facts this week. Try these for practice:

• Family of facts
• Relating multiplication and division facts
• Solving problems using multiplication facts

Grade 4 Test #2

• Unit rates
• Multiplying by 10, 100, 1000
• Dividing by 10, 100

Grade 4 Test #3

• Estimating products and quotients
• Multiplying 2/3 digit by 1 digit numbers (expanded form, algorithm)
• Dividing 2/3 digit by 1 digit numbers (repeated subtraction, algorithm)
• Solving multiplication and division problems (sharing, grouping, comparing)

Grade 5 Test #1
