Reactions
This site gives an extensive overview of chemical reactions. Visit this site and describe three different types of reactions.
Photosynthesis Directory
This site explains how plants use photosynthesis to store energy from the sun. Visit this site and explain how you end up using the energy from the sun that the plants store with photosynthesis.
Perpetual
Motion Machines
This private home page details how the second law of thermodynamics prohibits perpetual motion machines. Visit this site and explain why perpetual motion machines are impossible
to build.
Your
Digestive System and How it Works
Visit this site to learn how our bodies use food. Which type of food is a source of high energy? Choose three different foods you have eaten in the past week and determine what
you got from them, whether it be nutrients or energy.
Air
Pollution: Halogens and Ozone Depletion
Chemistry Visualized offers several videos and pictures demonstrating the theory of ozone depletion. Visit this site and explain why ozone depletion, if true, is a concern.
Catalytic
Converters
Here you can find some detailed videos and images that describe how catalytic converters work. Visit this site and discover how these devices make our air cleaner.

How
Things Work
A site maintained
by A. Bloomfield, the author of "How Things Work: the
Physics of Everyday Life." Students can read old questions
or ask Bloomfield their own. As a group, formulate a question
for Bloomfield and ask it.
The
Particle Adventure Home Page
An in-depth description of particles; includes a QuickTime
movie and various links to a variety of nuclear subjects.
Go through the adventure and write a journal entry about your
experiences.
Chemical
Bonds
Visit this site to read a brief description of the
various types of chemical bonding. Scroll down to read about
covalent bonds. What type of covalent bond is formed when
three pairs of electrons are shared?
Chemical
Bonds
Go to this site to read about chemical bonds and the
formation of compounds. Scroll down to read about ionic bonding.
Click on a simulation of the NaCl reaction. What happens to
the sodium atom in this reaction?
The
Periodic Table
Go to this site by the Los Alamos National Laboratory
to see an interactive periodic table. Click on any element
in the table to learn more about that element. For example,
click on copper. What is the element copper used for?
