Students will be able to:
use information from internet access and classroom discussions to
-solve density problems.
-use power writing to write up laboratory experience.
The do now was to solve density problems.
Students completed the write up of the lab on density using the power writing technique.
Students reviewed information on physical and chemical changes. This included that during a physical change, a substance changed only size, shape or state but that during a chemical change, a substance changed into something different with new chemical characteristics. Physical properties are those properties that can been seen: such as color, size, shape, state, density, boiling point, melting point, etc.
Chemical characteristics are only visible as they change into new substances. Evidence of a chemical change include:
giving off heat or removing heat from a system, color change, production of a smell, change in state, formation of a gas or a solid (precipitant).
Students also received HL #10, which can be found at the top of this blog.
