- "Objects and substances in motion have kinetic
energy. Objects and substances may have potential
energy due to their relative positions in a system.
Gravitational, elastic, and chemical energy are all
forms of potential energy."
Here your students can learn about the changes
between potential, kinetic and heat energy through
text, a series of hands on classroom activities
and even an online "Monkey Swing" game.
Students are to work in groups to gather data
regarding the relationship between the length
of the pendulum and the length of the time it
takes for one complete period. Once the students
graph the data, they are then asked to predict
the appearance of the graph if the length of the
pendulum as 2X or 0.5X the original length. The
teacher may adjust the difficulty of this lesson
according to the level of the student.

- "Energy is transferred from a source to
a receiver by radiation, conduction, and convection.
When energy is transferred from a source to a receiver,
the quantity of energy before the transfer is equal
to the quantity of energy after the transfer."
The best parts about this lesson plan are
the links to interesting sites that explain about
energy concepts. The end product of the
lesson is experiments that students have developed
and conducted that answer questions about heat
This site contains general information about
energy conversions. It gives examples of the most
important forms of energy and gives some examples
of objects that convert one form of energy into
another (e.g. electric power plant, automobile
Energy Quest is an award-winning energy education
website. Students click on items in a
room to go to various areas such as projects,
library, energy and transportation, homework
help, and how things work. Each area also
list several links to other information.
There is also a link for parents and teachers.
This site helps students to understand the basic
structure of a wave. It gives students the opportunity
to adjust different parts of a wave such as amplitude,
wavelength, wave speed, and phase shift. This
first page could be used for middle school students
was well as the link entitled waves, while other
links could be used for high school students to
look at the physics of how waves behave and the
trigonometric realms of waves.
Interactive: Energy and Magnetism
This interactive student activity introduces
the basic concepts of electricity and magnetism.
Shockwave must be installed on the browser. It
can be downloaded from the Macromedia Web site
Resources in the U.S. Electricity Supply
This would be a good site for student reports
on renewable resources used for electricity production.
This site provides general information.
Outstanding - This site provides teacher
lesson plans, background reading material, and
student activities that show molecular movement
at different temperatures. The graphics are great,
the student or teacher can choose ability level
from K-12, and the activities are interesting.
Easy to follow directions for students and teachers.
- "Nuclear reactions take place in the
sun producing heat and light. Only a tiny fraction
of the light energy from the sun reaches Earth, providing
energy to heat the Earth, and providing energy that
results in winds, ocean currents, and storms. Light
is also the primary source of energy for living things.
In plants, light from the sun is transferred and stored
as chemical potential energy through a process called
and The Sun New
Site explores how we get energy from the sun.
The site also has additional links.

a wave and a lot of information concering the
topic of light.

- "Waves transfer energy when they interact
with matter. Examples of waves include sound waves,
seismic waves, waves on water, and light waves."
of Baseball Bats
This site has animated wave patterns to show the
acoustical vibration of baseball bats. Compares
the vibration of a wood and aluminum baseball
bat. Uses familiar objects to teach science concepts.
Science: How We See Things
This site allows students to investigate the
bending of light using mirrors. A quiz is included.
Actual text book that explains how sound travels
through water. It explains the history of the
first time it was discovered that sound travels
through water. Shows what the sound waves look
like as they travel through water. Cool site!
This is a PDF file.
Excellent discription of vibrations. Has a
link to get more information at the bottom of
the page. Click on: Where Do You Go From Here?
and you are on your way.
of Sound in the Sea (DOSITS) New
Oceanographers, submariners, whales, dolphins,
seals, in short, all working or living in the
ocean use sound to sense their surroundings, to
communicate, and to navigate. This web site will
introduce you to the science and uses of sound
in the sea. Includes a sound gallery of 60+ sound
recordings and vibration patterns of various ocean
creatures to show how ocean depth, temperature
and salinity affect sound quality.

sound and speed of objects and then watch two
waves vibrate and create interference patterns
in this interactive simulation.Gizmo can only
be used once a day without having to join.

Five thumbs up. This has audio and reads the text
to the kids. You could read it as a class off
the computer, or have the kids listen to the computer
read the text and discuss the information after
the reading. There is also a mini quiz and animated
visuals… How Cool!!!
Science "Snacks", Resonator lab
In this "Snack", wooden dowels of varying
lengths, each loaded with the same mass, are vibrated
at identical frequencies. When the vibration matches
the resonant frequency of one of the dowels, that
dowel vibrates with a large amplitude. Materials
are listed to make a resonance demonstrator, probably
best used as demonstration. Simple instructions
and explanations provided.
