electrical and thermal conductivity. Some metals, such as aluminum (Al),
iron (Fe), nickel (Ni), copper (Cu), silver (Ag), and gold (Au), are pure
elements; others, such as steel and brass, are composed of a combination
of elemental metals.
• 1 d. Students know that each element is made of one kind of atom and that
the elements are organized in the periodic table by their chemical

properties.
• 1 f. Students know differences in chemical and physical properties of
substances are used to separate mixtures and identify compounds.
• 1 g. Students know properties of solid, liquid, and gaseous substances,
such as sugar (C6H12O6), water (H2O), helium (He), oxygen (O2), nitrogen
(N2), and carbon dioxide (CO2).
• 1 i. Students know the common properties of salts, such as sodium chloride
(NaCl).
Investigation and Experimentation:
• 6 b. Develop a testable question.
• 6 c. Plan and conduct a simple investigation based on a studentdeveloped question and write instructions others can follow to carry out
the procedure.
• 6 d. Identify the dependent and controlled variables in an investigation.
• 6 f. Select appropriate tools (e.g., thermometers, meter sticks, balances,
and graduated cylinders) and make quantitative observations.
• 6 g. Record data by using appropriate graphic representations (including
charts, graphs, and labeled diagrams) and make inferences based on
those data.
• 6 h. Draw conclusions from scientific evidence and indicate whether
further information is needed to support a specific conclusion.
• 6 i. Write a report of an investigation that includes conducting tests,
collecting data or examining evidence, and drawing conclusions.
Additional Information About the Day:
• Plan and conduct a simple investigation that others can follow.
