Groupwork:
Observation: The glowing wooden splinter catches fire because oxygen has been released.
Conclusion: Mercury oxide is a compound that decomposed as a result of heating. It broke up into oxygen (a gas) and mercury (a metal).
Mercury Oxide = mercury + oxygen
Group work:
Do the following experiment in your groups to determine whether mercuric oxide is a compound consisting of elements. Follow the different steps exactly:

Assessment
| MARK | LEVEL | COOPERATIVELEARNING SKILLS | VALUES AND ATTITUDES | CONTENT |
| 1-34% | 1 | Each learner learns individually. Participation in the group is destructive, e.g. domineering. | No respect for others. Destructive interpersonal relationships (actively negative). | Not able to come to meaningful observations and deductions. |
| 35-39 % | 2 | Does not contribute to the group and forms no meaningful part of it. | Not respectful towards others, but this does not affect interpersonal relationships (negatively passive). | Observations and deductions fairly sound. |
| 40-69% | 3 | Acknowledged as a member of the group. Sensitive to the needs of others. | Shows consideration for others and understanding of different points of view, but this has no effect on interpersonal relationships (positively passive). | Observations and deductions sound. |
| 70-100% | 4 | Creates opportunities for contributions by other members of the group. Always contributes positively to the group task. | Shows consideration for others and understanding of different points of view. Influences interpersonal relationships in a positive way (positively active). | Observations and deductions excellent. |
Learning Outcome 1: The learner will be able to act confidently on curiosity about natural phenomena, and to investigate relationships and solve problems in scientific, technological and environmental contexts.
Assessment Standard 1.2: We know this when the learner conducts investigations and collects data: organises and uses apparatus/equipment or sources to gain and record information;
Assessment Standard 1.3: We know this when the learner evaluates data and communicates findings: generalises in terms of relevant aspects and describes how the data support the generalisation.
