Feb 25 - March 1

This week we are planning to incorporate all forms of energy into our study, not just Heat or Thermal Energy. Each form of energy will fit under either POTENTIAL or KINETIC energy forms.

We will use the phrase MRS CHEN to remember all the forms

M - mechanical (KE)
R - radiant (KE)
S - sound (KE)
C - chemical (PE)
H - heat (KE)
E - electrical (KE)
N - nuclear (PE)

This study is leading to the understanding that each form of energy transforms into other forms of energy very easily.

For example:
A blow dryer converts electrical energy into heat and sound energy.
A turbine converts heat into mechanical energy which in turn becomes electrical energy.

Our week was filled with mini labs using toys to demonstrate the energy changes when using toys and everyday objects.

February 10-22

In this time, we finished studying about kinetic and potential energy.

We also began and ended a focus on the energy form thermal or heat energy (a subsection of kinetic energy). We discussed the 3 ways that heat can travel: conduction, convection and radiation.

We had a lab using a curly cue to demonstrate convection and a lab melting chocolate chips to mainly demonstrate conduction, but we tied in all 3 ways to transfer heat.

February 4 - 8

This week we started studying Physics. This will be a long unit covering the states and forms of energy and how energy relates to matter in motion (speed).

This week we started with the two major groups of energy--kinetic and potential energy---and the Law of Conservation of Energy.

We demonstrated the greatest amount of potential energy differs by object, but it is based on the position and mass of an object. Kinetic energy is the energy of matter in motion.

Vocabulary and cover page
to be completed as we go through different forms of energy

notes on KE and PE

Jan 25-Feb 1

This week we reviewed for the Benchmark over Life Science.

Benchmark was Feb 1.
