Rainbow Science Experiment Worksheet

Science experiments lesson 5: Make a rainbow with water and sunlight · Set 99 · 40 questions

What you do (Bend and split): 1. Fill a clear glass with water and set it on a steady, sunny windowsill. 2. Put white paper on the floor where the sunlight passes through the glass. 3. Move the paper or glass slowly until a rainbow appears. 4. Never look straight at the Sun.
