This learning resource introduces students to the properties and changes of matter through engaging activities and discussions. Students take on the role of 'Chemical Detectives' to investigate how substances interact and transform during various chemical reactions. The mission emphasizes observing physical and chemical properties, differentiating between physical and chemical changes, and recognizing indicators of chemical reactions such as gas formation, temperature changes, and color changes. Students are guided through a hands-on experiment where they create a chemical change using baking soda, calcium chloride, and water, allowing them to see evidence of gas production and the irreversibility of the reaction. Emphasis is placed on collaborative discussions and reflection on their observations, reinforcing key scientific concepts and encouraging curiosity about the nature of matter.
