Learning Objective

Students will be able to explore plant cells vs. animal cells.

Today's Lesson

In this lesson, we'll explore plant cells vs. animal cells. Scientific inquiry allows us to investigate and explain natural phenomena.

A cell is the smallest unit of life—the basic building block of all living things. Some organisms, like bacteria, are made of just one cell. Others, like humans, are made of trillions of cells! Each cell has parts that do different jobs: the nucleus controls the cell, the cell membrane holds it together, and other parts help with energy and growth. Think of cells as tiny factories that keep life going!

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.

Key Terms
Investigate

To examine systematically through observation and experiment

Evidence

Observable facts that support or refute a claim

Activities
Instructions
1. Read the background information on plant cells vs. animal cells. 2. Form a hypothesis before beginning. 3. Conduct the investigation following procedures. 4. Record observations and analyze results.
Materials Needed
  • Lab notebook
  • Investigation materials
  • Safety equipment if needed
Practice Problems
1

Name three things all living things need to survive.

Hint: Think about what you need every day.
2

Is a rock living or nonliving? Explain your answer.

Hint: Does it grow, breathe, or need food?
3

How is a plant different from an animal?

Hint: Think about how they get food.

Teaching Tip

For this age group: Balance direct instruction with collaborative activities. Allow students to explain their thinking and make connections to prior knowledge when exploring plant cells vs. animal cells.
