Separating Mixtures: Key Concepts and Techniques

The video tutorial guides students through an online activity on separating mixtures. It begins with instructions to access the FOSS website and navigate to the 'Mixtures and Solutions' section. The activity involves using different tools to separate components of mixtures, such as iron filings, sand, and salt. Students learn to use a magnet to remove iron filings and experiment with various tools to separate sand and salt, emphasizing trial and error to achieve correct results.

What is the first step to access the online tutorial on separating mixtures?
