MATTER AND ENERGY |
GOALS
The Matter and Energy Module consists of four sequential
investigations. Students experience a variety of forms of matter and
energy. They investigate the properties of light, observe the
conversion of energy from one form to another, and explore properties
of the three common states of matter (solid, liquid, and gas).
Students use metric tools to measure the properties of matter—mass,
volume, and temperature—and observe that starting substances can
change into new substances as a result of a chemical reaction.
FOSS EXPECTS STUDENTS TO
• 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 takes 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 refl ect from the surface of a mirror.
• Learn that white light is a mixture of all colors of light, that
matter can absorb and refl ect 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 refl ects; observe that the apparent color 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.
• Learn that all matter is made of particles.
• 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.
