Easy plant parts experiment for first graders.

🌱 Easy Plant Parts Experiment for First Graders: A Teacher's Guide

This lesson plan helps first graders understand the basic parts of a plant (roots, stem, leaves, and flower) and their functions through a hands-on experiment.

🎯 Objectives

• 🔍 Students will be able to identify the four main parts of a plant: roots, stem, leaves, and flower.
• 🌿 Students will be able to describe the basic function of each plant part.
• 🧪 Students will be able to conduct a simple experiment to observe how plants absorb water.

📦 Materials

• 🌷 White carnations or celery stalks
• 💧 Clear glasses or jars
• 🌈 Food coloring (various colors)
• 🔪 Knife or scissors (for teacher use only)
• 📏 Ruler
• 📝 Observation Worksheet (see Assessment section)

☀️ Warm-up (5 minutes)

Start by asking students what they know about plants. Use questions like:

• ❓ What are some plants you see every day?
• 🤔 What do plants need to live?
• 💬 What parts of a plant do you know?

Write their answers on the board to create a foundation for the lesson.

🔬 Main Instruction (25 minutes)

1. Preparation (5 minutes):
• 🌈 Divide the class into small groups.
• 💧 Fill each glass or jar with water.
• 🎨 Add several drops of food coloring to each glass, using different colors for each.
• 🔪 (Teacher Only) Carefully cut the bottom of each carnation stem or celery stalk at an angle. This helps the plant absorb water more effectively.
2. Experiment Setup (5 minutes):
• 🌷 Place one carnation or celery stalk in each colored water glass.
• 📏 Use a ruler to measure the initial height of the water in each glass. Record this measurement on the board for later comparison.
3. Observation (15 minutes):
• 👀 Explain to the students that they will observe the plants over the next few hours or days to see what happens.
• 📝 Distribute the Observation Worksheets (see Assessment section).
• ✍️ Guide students to record their initial observations: What color is the water? What do the plants look like now?
• ⏰ Over the next few hours/days, encourage students to regularly check their plants and record any changes they observe (e.g., color changes in the petals or leaves).
• 💬 Facilitate a class discussion about their observations. Ask: What is happening to the plants? Why do you think the colors are changing?

✅ Assessment (10 minutes)

Use the following Observation Worksheet to assess student understanding. Adapt as needed for your class.
