STEM skills – to which the learning unit is related to

CORE STEM SKILLS

Asking questions

Analysing and solving problems

Designing experiments

Drawing conclusions based on results

Motivation to learn and engage

Self-discipline and self-regulated learning (cognitive autonomy)

ADDITIONAL SKILLS

Sharing ideas

Teaching methodologies/activity outline

1 – Designing experiments to prevent browning in apple.

2 – Talked about why apple brown and discussed the comparison with rusting (oxidation).

3 – Ask questions such as- How do you thing is the better to prevent browning in apple?

4 – Give them time to experiment with apples and different substances.

5 – Observe and record results of the experiment.

6 – Drawing conclusions based results.

Assessment of learning

Initial evaluation

Get to know the previous knowledge they could know about the same theme.

Continued evaluation

Progressively acquire basic habits of autonomy in everyday actions, to act safely and effectively.

Think, create, elaborate explanations and start the basic chemical skills.

Observe and explore the immediate, natural and chemical reactions, with an attitude of curiosity and respect and gradually participate in social and cultural activities.

Participate in the chemical experiment with a progressive understanding of the necessity of some norms.

Use the oral language for describe the chemical reaction with scientific vocabulary.

Drawing conclusions based on observed results

Final evaluation

To evaluate the learning objectives, use the chart in which the more important elements will be highlighted.
