Unit Goals/Objectives

�      Apply the conventions of measurement

�      Use tools to make accurate measures and represent measurements by using numbers and units

�      Plan a procedure, and use it to solve a problem

�      Weight materials to confirm conversion of matter

�      Investigate the relationship of simple mixtures; mix materials to observe solutions and reactions

The Measurement unit consists of four investigations �

1)            The First Straw
Key Content Establishes units; meter is the standard unit for distance; sub units are kilometer, centimeter, and millimeter

2)          Fact of the Matter
Key Content matter exists in 3 phases; phases have defining characteristics; liter is the standard unit for volume; gram is the standard unit for mass; graduated cylinders and syringes are used to measure volume; mass is measured with a balance and mass pieces

3)           Changing Matter
Key Content temperature is a measure of how hot matter is; Celsius is the unit used for temperature; solids melt into liquids; liquids evaporate into gases; water moves in the water cycle; earth materials heat up in the sunshine

4)          Mixtures
Key Content mixture is two or more material; mixtures can be separated; solutions result when a solid dissolves in a liquid; starting materials change into new materials during chemical reactions; mass is neither created or destroyed during physical and chemical interactions
