We will be finishing up state changes ( boiling, melting, freezing) on Monday and Tuesday , allowing us to move on to energy on Wednesday, and thermal energy on Thursday and Friday.

On Monday I will be sending home a sheet of homework, a few problems from which will be due every day. For more detail, as well as an uploaded copy, please visit the homework section of my site. I have uploaded copies of our reading, as well as some journal entries that we will be doing throughout the week. In addition, I have attached the word file of a card sort that we will be doing in class on Wednesday. Please remember, on Friday we will have our weekly assessment over what we learned this week, including the five vocabulary words from the vocabulary sheet sent home this Monday.

ENERGY: is very different from matter!

When we talk about matter, we talk about actual objects, whether it be a solid, liquid, or gas. Matter has mass and has volume- it can mix or dissolve.

Energy, on the other hand, does NOT have a mass or a volume. Energy is a force.

For our purposes, the official definition will be that ENERGY CAN CHANGE MATTER, or that it is the ABILITY to CAUSE CHANGE in matter.

The five kinds of matter that we will study this year are:

  • Sound Energy

  • Mechanical Energy

  • Light Energy

  • Electrical Energy

  • Thermal Energy

The first kind of energy we will study will be THERMAL ENERGY

Thermal energy is caused by fast moving particles. The faster the particles move, the more thermal energy, or heat, is created.

Some common sources of thermal energy would be:

    • candles

    • microwave

    • fire

    • oven

    • the sun

    • friction ( rubbing objects against one another such as a foot on a carpet)

    • electronic devices

Following is a variety of material that will help you explore these ideas further online:
