The Matter and Energy Module consists of four sequential investigations
to introduce the multiple forms that matter and energy can take and to
give students experience with the transfer of energy from one form to
another. Light absorption and reflection is the focus of an entire investigation.
Students also conduct and observe chemical reactions and are introduced
to atoms and elements.
Students will
|
• |
Learn that light from the Sun is the source of most
of the energy on Earth. |
| |
• |
Observe energy sources doing work and learn how energy
(light, heat, motion, chemical, electric) can be converted from one
form to another. |
| |
• |
Learn that stored energy take many forms; machines
and organisms can convert energy into motion and heat. |
| |
• |
Describe how energy can be carried from one place
to another by waves, electric current, and moving objects. |
| |
• |
Learn that light energy travels in straight lines
from a source. |
| |
• |
Find out how light can reflect from the surface of
a mirror. |
| |
• |
Learn that an object is seen only when light from
that object enters an eye. |
| |
• |
Learn that white light is a mixture of all colors
of light, that matter can absorb and reflect light, and that a shadow
is the dark area behind objects that block light. |
| |
• |
Learn that the apparent color of an object is the
result of the light it reflects; observe that the apparent colors
of an object is affected by the color of light striking it. |
| |
• |
Explore properties of the three forms of matter (solid,
liquid, and gas), including change of state. |
| |
• |
Use metric tools to measure mass, volume, and temperature
and make multiple numerical observations to improve accuracy. |
| |
• |
Observe and analyze a chemical reaction. |
| |
• |
Collect and analyze data to develop logical conclusions. |
| |
• |
Predict the outcome of an event and compare the results
with the prediction. |
