5th Grade Mixtures and Solutions
Content Standard II: Physical
Essential Learnings:
What do students need to know and be able to do?
Big Ideas:
1. Experimental Design (observations, question,
hypothesis and design)
2. Scientific testing (conduct investigations, collect
and organize data)
3. Analysis and Conclusions (analysis trends, and
conclusions)
4. Structures and Properties of Matter
5. Sources and Properties of Energy
Students will…..
Observe objects have many observable properties, including size, weight, shape, color,
temperature, and the ability to react with other substances.
Identify a substance has characteristic properties, such as density, a boiling point, and
solubility, all of which are independent of the amount of the sample. A mixture of
substances often can be separated into the original substances using one or more of the
characteristic properties.
Observe substances react chemically in characteristic ways with other substances to form
new substances with different characteristic properties. In chemical reactions, the total
mass is conserved.
