Science Assessment – Electricity Review
ELECTRICITY
April 26, 2010
*You will be able to use your Science notebooks during the assessment. Make sure you have this information in your books!*
For homework, you should be completing the electricity unit on Learning.com. There will be an assessment question taken directly from Learning.com
Electricity
* Electricity is a type of energy
* Electricity occurs when there is a transfer of electrons (the negative part of an atom)
* There are two types of electricity: static electricity and current electricity
Static Electricity
* Static electricity is caused when two different objects are rubbed together to create friction (one object becomes positively charged, and the other becomes negatively charged)
* Static electricity has a sudden transfer of electrons, which can result in a spark or two things sticking together
* Think of examples of static electricity in everyday life: lightning, shocking someone after you rub your feet on the carpet, rubbing a balloon on your hair
Current Electricity
* Current electricity is electricity that is moving or flowing through wires. Current electricity operates all of our lights, electronics etc.
* The flow of energy in current electricity travels through a circuit. In a circuit, there is an energy source, a path (wires) and an output device (lightbulb)
* A circuit is an unbroken pathway along which electrons travel. What would happen if there is a break in the circuit?
* A conductor allows electrons to flow through easily (metal), but an insulator does not allow electrons to flow through (wood, plastic)
Different Types of Energy
* Electrical energy can be turned into many different kinds of energy: light, heat, mechanical and sound.
* Think of our everyday appliances. What kind of energy does a toaster convert from electrical energy?
Electricity and the Environment
* In class, we have discussed several ways in which we can conserve electricity and why it is important to the environment
* Some examples include: turning off your lights when no one is in the room, unplugging appliances that aren’t being used, hanging your clothes to dry outside instead of using the dryer, etc.
Assignment – Writing Activity: Using your blog, write a narrative essay that persuades the reader to conserve electricity.
This will be done on Monday May 3, 2010.
Water Everywhere
In the following webite: Shambles.net The author lists many resources about WATER with topics ranging from the water cycle, water videos, water in schools, how we get our water, etc.
Think about WHY the author of this blog is posting resources about water. What is his motive? What is his interest? Investigate.
Your job is
1) to review 2-3 of the resources provided in this website. Pick one that relates to our unit on Electricity, Environment.
2) Post the link to the resource and explain WHY you feel this resource is worth investigating further or sharing with others.
3) Can you find one additional resource about Water?

What’s the Big Idea?
Students will collaborate and discuss our Big Idea for the Language/Science Unit -
Why is it important to study space exploration?
How can new discoveries help us in our own lives?
Collaborative Research
As part of our combined literacy and science unit, students in Grade Six will be actively researching and learning about the diversity of things, the classification system that scientists use to understand and group living things on Earth, and the characteristics of vertebrates and invertebrates.
As students read the informational reports and explanations, and magazine covers and contents, they will develop:
- Reading comprehension strategy of visualizing and inferring
- the writing strategy of planning for concise writing
- the ability to identify characteristics of magazine covers and websites and their contents
- an understanding of the characteristics of descriptive text patter
- word study skills
- using scientific knowledge to create a SCIENCE FICTION STORY
Through this collaborative language unit, students will use wikispaces to combine research topics.
