This unit is a great way to introduce
younger students to the properties of matter and an excellent
physical-science unit for primary grades. In a series of fun
and fluid activities, young students explore the ubiquity and
properties of liquids using introductory language and simple
concepts. They play a classification game, observe how food
coloring moves through different liquids, and create secret
salad-dressing recipes and an "Ocean in a Bottle."
The Raindrops and Oil Drops activity
can prompt discussion of environmental issues such as oil slicks,
and was used in many Alaska schools to educate students about
the 1989 Exxon Valdez oil
spill. Literature connections, resources, and assessment
suggestions are provided to help teachers make the most of the
Time: Five or more class sessions.
