SC15.5.1

Science (2015) Grade(s): 5

SC15.5.1
Plan and carry out investigations (e.g., adding air to expand a basketball, compressing air in a syringe, dissolving sugar in water, evaporating salt water) to provide evidence that matter is made of particles too small to be seen.

Scale, Proportion, and Quantity

Knowledge

Students know:

Matter is made of particles too small to be seen Matter too small to be seen still exists and may be detected by other means.
Gasses are made of matter particles that are too small to see, and are moving freely around in space (this can explain many observations, including the inflation and the shape of the balloon, and the effects of air on larger particles or objects).
The behavior of a collection of many tiny particles of matter and observable phenomena involving bulk matter (e.g., an expanding balloon, evaporating liquids, substances that dissolve in a solvent, effects of wind).
There is a relationship between bulk matter and tiny particles that cannot be seen.

Skills

Students are able to:

Identify the phenomenon under investigation.
Identify evidence that addresses the purpose of the investigation.
Collaboratively plan the investigation.
Collect and analyze the data.

Understanding

Students understand that:

Natural objects exist from the very small to the immensely large.
