Neat Images for Models and Designs
This page offers a compendium of video clips, animations,
photographs, examples of scientific illustration, or other
images that could complement your classroom explorations.
Clockworks from Sundials to the Atomic Second
This lovely site from Brittanica.com
offers an animated exhibition explaining the sundial,
clepsydra, astrolabe, candle clock, sandglass, weight driven
clock, spring driven clock, pendulum clock, quartz watch,
and cesium atomic clock. Requires Shockwave.
Escapements in Motion
This amateur clock enthusiast has put together this site
that features some amazing animations of different types of
clock escapements (the gears that keep the time). Using
these images could be a good way to show students what the
insides of clocks look like and what they do.
Batteries Movie
Check
out this animated movie from BrainPOP that explains and
illustrates exactly how batteries work. The explanation gets
a little complicated, so the visuals are especially helpful
in keeping it from getting too confusing.
Cars Movie
The
friendly animated science folks at BrainPOP offer this short
movie that explains how car engines work, carefully
illustrating the roles of the pistons, fuel, spark plug, and
more. This is a good movie for students learning about
vehicles and for adults who'd like to know more about how
their cars work.
Inclined Plane Movie
This animated BrainPOP movie uses a question about ramps as
a starting point to explain what inclined planes are, what
work is and how inclined planes can modify work, as well as
where inclined planes show up in everyday life.
Levers Movie
BrainPOP reveals how levers work through clever animation.
They explain how levers magnify effort, detail the parts of
levers (lever, load, fulcrum) and show real-life examples of
levers and their applications, all in an appealing, kid-
friendly way.
Phases of the Moon
From the Astronomy Department at the University of Maryland,
this simple page explains and illustrates the phases of the
Earth's moon. This is a handy, straightforward
reference.
Line and Point Symmetry
This teacher has created short and pictorial
descriptions and mini-lessons dealing with line and point
symmetry. This site is very helpful for illustrating exactly
what symmetry means.
Photo Activity for Symmetry
Here's a fun little activity that drives home the
idea of line symmetry, made especially easy if you have
access to a digital camera. Using a photograph, the activity
demonstrates what happens when you draw a vertical line of
symmetry though a picture of a face, and then use the halves
to make interesting composite pictures. Worth a look!
How Paper Is Made
The
Idaho Forest Products Commission's website for kids offers
this section that explains each step of how paper is made.
There's also a very nice short movie linked at the bottom of
the page that clearly explains how paper tissue (as used in
toilet paper, facial tissues, and napkins) is made.
From Pulp to Paper
This site, written for kids, walks you though each step of
how recycled paper is made. Each step has good animations
that illustrate the process. It features straightforward
language appropriate for adults and students.
Watermarks in Paper
The American Museum of Papermaking presents this fascinating
information and about how watermarks are created, including
the history of watermarks and some beautiful images. This
could be a neat site to show students working with the
Technology of Paper kit as they explore papermaking.
The Elements of Machines
Featuring photographs and brief text explanations, this
page from the Boston Museum of Science provides an overview
of the most common simple machines as well as machines that
build upon the elements of simple machines, such as gears,
cams, and chains and belts.
