1. Exploring Density: Fill different containers with water, oil, and syrup. Have students observe and predict which liquid will be the heaviest and which will be the lightest.
2. Sink or Float: Gather various objects and have students predict whether they will sink or float in water. Then, conduct experiments to test their predictions.
3. Magnetic Magic: Introduce magnets and let students explore different objects to see if they are attracted to the magnets. Encourage them to document their findings.
4. Planting Seeds: Let students plant seeds in small pots and observe their growth over time. Discuss the importance of sunlight, water, and nutrients for plant growth.
5. Volcano Eruption: Create a volcanic eruption using baking soda, vinegar, and a model volcano. Discuss the science behind the chemical reaction that causes the eruption.
6. Rainbow in a Jar: Layer different liquids with different densities to create a rainbow in a jar. Discuss how each liquid forms a separate layer due to its density.
7. Balloon Bounce: Inflate a balloon and have students explore how it behaves when rubbed against different materials like fabric, hair, and plastic.
8. Germination Experiment: Conduct a germination experiment using different conditions like light, darkness, water, and no water. Observe and discuss how the conditions affect the seed’s growth.
9. Melting Ice: Provide ice cubes and different materials like salt, sand, and sugar. Let students experiment with these materials to see which one melts the ice fastest.
10. Rainbow Milk: Pour milk into a shallow dish and drop food coloring in different spots. Then, add a drop of dish soap and observe the colorful reaction caused by surface tension.
11. Sound Science: Gather various objects and have students explore how different materials produce different sounds when struck or rubbed against each other.
These science projects aim to spark curiosity and engagement in first-grade students while introducing them to basic scientific concepts. Encourage discussion, exploration, and documentation throughout each project to enhance their learning experience.
