Using multiple models in science | 14–16 years

Use this activity to reinforce the idea of multiple models being used in science, and enhance your learners’ skills to interpret and evaluate different models of the same concept. This can also promote retrieval practice of keywords such as atom, molecule and a covalent bond through discussion. Classroom slides, a student worksheet and teacher notes including advice on differentiation and example answers are provided. 

Learning objectives:

1. Use a variety of models to develop scientific understanding of a molecule of hydrogen.
2. Discuss limitations of models in science.

The student worksheet contains five different models and representations of a hydrogen molecule. The questions will guide learners to evaluate each model.
