Matter, Energy, and Organization in Living Systems
(9-12) * All matter tends toward more disorganized states.
Living systems require a continuous input of energy. * The
energy for life primarily comes from the sun. * The
chemical bonds of food molecules contain energy. * The
distribution and abundance of organisms in ecosystems are limited by the
availability of matter and energy. * As matter and
energy flows through the levels of life, matter and energy are
conserved. (NSES,
1996)

This "learning tool" is
called
Food Chain. One of the most innovative science education
companies is
Explorelearning.com, they call their simulations, Gizmos. They are a
subscription site,
but they allow you to see this Gizmo for 5 minutes.
Shockwave is required. |

The name of this "learning tool" is called
Photosynthesis.
The elegant and conceptually clean animations of
John Kyrk will lead your students
through the fascinating world of the energy source for most life on the
planet Earth. Just click the small green arrow on the left side to advance
the animations. The work of John Kyrk is really incredible, please visit
his web site to see more biology related visuals! |

NASA continues to be a leader in science
education! This "learning tool" is called the "Earth
Observatory: Data & Images". Here you can explore data sets in a very
visual way. Scroll your mouse over Atmosphere, Oceans, Land, Life on
Earth, and Heat & Energy to see the specific variables you can choose.
Select the variable and then build an animation to see it change over
time. In LAND , you might want to select Landcover Classification to see
ecosystems over time. |

This "learning tool" is an applet which
clearly explains the predator prey relationship in ecology. The name of
this interactive is
Predator and Prey, it uses the classic relationship of the Canadian
Lynx and the Snowshoe rabbit. On the second page make sure you hit the
"Graph" button to get to the interactive graph. This tool is brought to us
by McGraw Hill. |

NASA has always been a leader in science
education. The name of this "learning tool" is called
Predator-Prey.
This simulation is conceptually clean and clear. From NASA CT
Science Interactives. Thanks. |
