Throughout our electricity unit third grade scientists have asked thoughtful questions. Recently, we sorted our questions into two groups. Some of the questions were "researchable." That means we could find the answers by asking someone, searching on the internet or searching in a book. The questions we focused on were "testable." That means third grade scientists could safely find the answers by using scientific equipment.
Third grade scientists are working in  pairs to answer some of those questions. They figured out which materials they need to use. They described the set up and wrote the directions so that any other scientist would be able to repeat the investigation.
Finally, they are giving it a try. Third grade scientists are using many different size batteries, different kinds of wire, light bulbs, motors, and switches to answer their questions. They are collaborating to set up circuits, ask questions and observe. It's exciting work that will be continued on Monday. 
Ask your third grader about their questions for an electrical investigation. :o)

Last week we practiced measuring things to the nearest 1/4 inch. It is tricky to identify those small lines that indicate fractions of an inch. But we reviewed our knowledge of fractions which helped us to understand. We also practiced measuring to the nearest centimeter. It's also important for third grade mathematicians to remember to line their measuring tool up carefully with the edge of what they're measuring. 
The more experience with measurement that children get at school and at home, the better. Encourage your child to estimate and measure distances. Typical questions that might come up at home include these:
How far is it across our kitchen table - and can we really reach that far?
How many children can sit comfortably on our couch? How many adults?
Will that extra bookcase really fit in the kids' bedroom?
These are good questions, and they're also very practical ones! Measurement questions come up a lot in our home lives, and it's exciting for children to be involved with real-world issues.
Here's how you can help during this unit:
Listen to your child's strategies for measuring.
Involve your child in your own measurement activities - hobbies like sewing or carpentry are a natural for this.
Happy measuring!
