An introductory presentation on grams and kilograms, defining each unit, providing common examples, and explaining the conversion between them.

Section role: This presentation supports the 'The Gram and the Kilogram: Small vs. Large' section, accompanying the teacher's explanation of mass units. The teacher will use the slides to visually introduce each unit, show concrete examples, and clearly illustrate the conversion between grams and kilograms. Slides: (1) Title Slide — 'Grams and Kilograms: Measuring Mass' with an engaging visual of a balance scale; (2) What is Mass? — bullet points defining mass as 'how much stuff is in an object' and clarifying its difference from weight; (3) Introducing the Gram (g) — defines gram as a unit for light objects, with visuals of a single paperclip and a grape; (4) Common Gram Examples — displays images of items typically measured in grams such as a cherry, a feather, and a pencil; (5) Introducing the Kilogram (kg) — defines kilogram as a unit for heavy objects, with visuals of a liter of water and a large dictionary; (6) Common Kilogram Examples — displays images of items typically measured in kilograms such as a cat, a bicycle, and a backpack; (7) Grams vs. Kilograms: Misconceptions — presents contrasting visuals like a large balloon next to a small fishing weight, prompting students to consider that size doesn't always equal mass; (8) The Big Connection: 1,000 Grams = 1 Kilogram — clearly states the conversion rule (1,000 g = 1 kg) with a visual representation of 1,000 small items equaling one large item; (9) Why Do We Need Both? — briefly explains that different units help measure different-sized objects efficiently; (10) Think & Discuss — 'Would you measure a pencil in grams or kilograms? How about a bicycle?' — this question hands control back to the teacher for an interactive discussion, building on the concepts introduced in the previous 'Heavy or Light?' section and setting up the 'Metric Unit Match-Up' activity.
