Objective
By the end of this lesson, you will be able to follow a planned procedure to undertake safe, ethical, valid, and reliable investigations in science.
Materials and Prep
Materials needed: pen, paper, ruler, various household items for experimentation
Prep: Find a quiet workspace with access to water and a flat surface for experiments.
Activities
- Experiment with Density: Use different household items to explore density. Predict which items will sink or float in water based on their density.
- Build a Homemade Volcano: Create a chemical reaction using baking soda and vinegar to make a mini volcano eruption. Observe the reaction and explain the science behind it.
- Investigate Light Refraction: Fill a glass with water and place a pencil inside. Observe how the pencil appears bent due to light refraction. Try different angles and depths to see how light behaves.
Talking Points
- "Today, we will learn how to conduct scientific investigations in a safe and reliable manner. This will help us understand the world around us better."
- "When conducting experiments, it's important to follow a procedure step by step to ensure accurate results. This helps us draw valid conclusions."
- "Always consider the ethical implications of your experiments. Treat living organisms and the environment with respect."
- "By being thorough in our investigations, we can ensure that our results are reliable and can be trusted by others."
- "Remember, science is all about curiosity and discovery. Don't be afraid to ask questions and explore new ideas."
