Lesson: Observation Tubes (K-2) (This lesson covers many of your Nature of Science Benchmarks, but not all of them.
Big Idea 1: The Practice of Science
SC.2.N.1.1: Raise questions about the natural world, investigate them in teams through free exploration and systematic observations, and generate appropriate explanations based on those explorations.
SC.2.N.1.2: Compare the observations made by different groups using the same tools.
SC.2.N.1.3: Ask "how do you know?" in appropriate situations and attempt reasonable answers when asked the same question by others.
SC.2.N.1.4: Explain how particular scientific investigations should yield similar conclusions when repeated.
SC.2.N.1.5: Distinguish between empirical observation (what you see, hear, feel, smell, or taste) and ideas or inferences (what you think).
SC.2.N.1.6: Explain how scientists alone or in groups are always investigating new ways to solve problems.
