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

Next, it was time to investigate a liquid,
grape juice, to be exact!
Mrs. Ranney gathered the following materials:
a jug of grape juice, 22 one-ounce cups, 22 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 it was room temperature.
Mrs. Ranney used the dropper to
give each student a 1 mL taste.
Most of us determined that the flavor was sweet and tasted like grapes.
The 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!
We observed some physical properties had changed.
For example, the texture was first slippery and smooth,
but quickly changed to rough and crunchy!
The temperature was definitely not room temperature anymore!
Science can be 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 using your five senses.
