7. Working Scientifically Skills
7.1 Identify issues relating to reliability, accuracy and validity in designing fair tests for investigations.
7.2 Design, conduct and report on a fair test by:
a. writing an aim and hypothesis
b. identifying steps in a method and selecting appropriate equipment
c. writing a risk assessment
d. recording data and/or observations
e. presenting data in relevant tables and graphs
f. writing a discussion and conclusion to complete the experimental report.

Part 1:
1. Use a measuring cylinder to pour 20 ml hydrochloric acid in a test tube.
2. Place a thermometer in the test tube and note the temperature of the acid.
3. Leaving the thermometer in the acid, add a 5 cm strip of magnesium ribbon and swirl the test tube gently.
4. Hold the test tube to see how warm or cool it feels. Record any change in temperature.
Part 2:
1. Use a measuring cylinder to pour 20 ml vinegar in a test tube.
2. Place a thermometer in the test tube. Note the temperature.
2. Leaving the thermometer in the vinegar, use the spatula to add about a teaspoon of baking soda to the test tube.
3. Hold the test tube to see how warm or cool it feels. Record any change in temperature.
