K2L12 Eggs-periment

Lesson Duration: 45 minutes

Grade: K2

Preparation Time: 15 minutes

Learning Objectives

- Children will explore the physical properties of eggs using their senses.

- Children will enhance their English vocabulary by describing observations.

- Children will make predictions and compare findings in a scientific manner.

Materials Needed:

- 4 eggs (2 raw and 2 boiled, unmarked)

- 2 balance scales

- A collection of blocks for weighing

- 2 tall transparent containers filled with water

- Worksheets for recording observations

- Song: I Love Science Song 

Preparation:

- Familiarize with the I Love Science Song to share in the children's joy.

- Familiarize with the related subject knowledge to ensure the smooth flow of the demonstration and explorations.

- Charge the atmosphere with a positive vibe, ready to encourage and assist the young explorers.

- Review the safety precautions and procedures for the experiment.

- Set up tables for children to sit in groups with the required materials.

- Prepare the materials on each table without indicating which eggs are boiled.

Lesson Procedure

1. **Warm-up Singing (5 minutes)**

   - Fill the room with music and excitement!

   - Play the I Love Science Song and guide our little scientists in song and dance. The I Love Science Song is our anthem for curiosity and joy.

2. **Engagement (10 minutes)**

   - Introduce the day's activity with a fun fact about eggs and their importance in science.

   - Assign 2 eggs to each table, without revealing which group has the raw or boiled eggs.

   - Emphasize the importance of handling the eggs gently and not tasting them during the exploration.

   - Guide the children to use their senses of sight, touch, smell, and hearing to examine the outside of the egg and describe its features.

3. **Exploration (15 minutes)**

   - Guide the children to use the balance scale to measure the egg's weight using blocks.

   - Instruct the children to record the weight on their worksheets.

   - Initiate a discussion on whether they think their egg will float or sink when placed in water, encouraging them to share their thoughts.

   - Proceed to test their predictions by gently placing the eggs in a container of water and observing the outcome.

   - Move on to examine the inside of the egg by cracking it open carefully into a provided box at the teacher's signal.

   - Encourage them to observe the differences between a raw and a boiled egg from the inside, using their observations to verify their earlier predictions about buoyancy.

4. **Observation and Discussion (10 minutes)**

   - Compare the recorded weights and visual observations from both teams.

   - Facilitate a discussion to help children understand the characteristics of raw versus boiled eggs based on their hands-on experiences.

5. **Tidy Up (5 minutes)**

   - Time to tidy up! Make it fun – who can be the neatest explorer?

   - Reflect on the day's journey with a simple recap of their scientific adventure.

   - Offer heartfelt praise for their efforts and the new knowledge they've gained.

6. **Ending (if time allows)**

   - As we close, sing once more. The I Love Science Song is our anthem for curiosity and joy.

## Teacher Note:

- Your positive energy sets the tone for the class; infuse each moment with encouragement.

- Prepare thoroughly to ensure you can confidently guide the children through the investigation.

- Safety is paramount; ensure all children handle the eggs and equipment carefully.

- Foster a spirit of exploration and experimentation, praising each child's efforts and discoveries.

- You're not just teaching facts; you're igniting a lifelong passion for learning. Your support is invaluable to their development.
