Biology (Stage 1)

CELLS AND ORGANISMS

LEARNING GOALS COMMON TO ALL SCIENCES

formulate a research question with a prediction
Recall that in a fair test only one factor/variable may be changed
Select a suitable method from a choice of different experimental methods

Identify independent, dependent and controlled variables in a given experimental procedure.

Organize data in a table and draw a bar and/or scatter graph
Describe the trend in a graph
Identify a mistake in a method that failed to allow for a fair test
Summarize the findings of an experiment
Apply basic scientific language correctly.

Identify and interpret the hazard symbols denoting harmful, toxic, flammable, oxidizing and corrosive.

State the uses of common laboratory glassware such as beaker, conical flask, measuring cylinder and test tubes
State the name of the equipment for measuring time (stop watch/stop clock), mass (electronic balance/ beam balance/Balance), temperature (thermometer), volume of liquid (measuring cylinder) and volume of gas (gas syringe/ inverted measuring cylinder)
