Elements in living things (CHNOPS)
Content is AI-assisted and continuously improved through educator review
Learning Objective
Students will explore elements in living things (chnops) through guided practice and application.
In this lesson, we'll explore elements in living things (chnops). Scientific inquiry allows us to investigate and explain natural phenomena.
Living things, also called organisms, have special characteristics that make them alive. All living things: 1) Need food, water, and air, 2) Grow and change over time, 3) Reproduce (make more of their kind), 4) Respond to their environment, and 5) Get rid of wastes. Plants, animals, and even tiny bacteria are living things. Rocks, water, and toys are not living because they don't do these things.
As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.
Take notes on key points and make connections to what you've already learned in previous lessons.
To examine systematically through observation and experiment
Observable facts that support or refute a claim
Instructions

- Lab notebook
- Investigation materials
- Safety equipment if needed
Name three things all living things need to survive.
Is a rock living or nonliving? Explain your answer.
How is a plant different from an animal?
Teaching Tip
For advanced learners: Encourage deeper analysis and real-world connections. Consider extension activities that allow students to apply elements in living things (chnops) to novel situations.
