The first science unit of the year will focus on matter.
Matter can be found in
3 states: solid, liquid, or gas.
We learned that all matter has physical properties.
We observed the physical properties of our inflatable globe. We posted adjectives that described the physical properties:
color, temperature, shape, size, texture, hardness, and
flavor.

Next, it was time to
investigate a liquid, grape juice to be exact.
Mrs. Yollis gathered the following materials: A jug of juice, 23 one-ounce cups, 23 popsicle sticks, and an eye dropper.
We studied the physical properties of the liquid. For example, we observed that the
color was purple, it took the
shape of the container, and was room
temperature. Mrs. Yollis used the dropper to give each student a 1 mL taste. We determined that the
flavor tasted like grapes and was sweet. The juice cups were filled and moved to the freezer.
What do you think happened?
Because the temperature in the freezer was 32˚ F, the liquid changed form! The juice was now a delicious
solid! Some
physical properties had changed. For example, the
texture was slippery and smooth, but quickly changed to rough. The
temperature was definitely NOT room temperature anymore.
Science is deliciously fun!

Science extra credit: At home, find one
liquid or one
solid to observe.
Please describe as many
physical properties as you can!
Remember: Physical properties are anything that can be
observed about an object by using your five senses.
