Anika and Ava are working on a science project. They need to break down big questions into smaller, manageable parts. What is this process called?

• Decomposition reactions

• Operationalisation

• Scientific method

• Hypothesising

Imagine Benjamin and Grace are conducting an experiment. The independent variable in their experiment is
