Two-year-olds are like little scientists, eager for sensorial insights that help them answer questions like, “What is this?” “How does this work?” Your curious toddler may love to compare objects that are heavier and lighter than one another. You can introduce comparative and superlative vocabulary, too, by labeling items “heavy, heavier, heaviest” and “light, lighter, lightest.” Try this activity next time you head outside with your little one!
