Grow a Rainbow Experiment - such a fun and easy science experiment for kids! • You will need: • Paper towel • Washable markers • Water • Identical glasses • Instructions: • 1. Fold the paper towel in half. • 2. Draw the rainbow colors on one end of the paper towel in rectangular blocks. • 3. Repeat the same on the other end. Make sure the colors line up on both ends. • 4. Pour water into the two glasses until they are about 3/4 full. • 5. Place the two ends of the paper towels into the cups. 1/2 of the rainbow blocks should be in the water. Do not fully submerge the entire colored portion of the paper towel in the water. • 6. Watch the colors travel up the paper towel! • Science Behind: • The capillary action is what causes the water to move up the paper towel. Water adheres to the walls of the small vessels in the paper towel, causing an upward force on the liquid at the edge. Plants and trees use capillary action to live. Water is absorbed by the roots, and capillary action allows the water to travel up the plant. • ➜ Miry's Classroom on Facebook: / mirysclassroom • ➜ Miry's Classroom on Instagram: / mirysclassroom • ➜ Miry's Classroom on Pinterest: https://www.pinterest.se/Mirysclassroom/ • ➜ Miry's Classroom on TikTok: / mirysclassroom • SUBSCRIBE to Miry's Classroom: / @mirysclassroom2363 • #sciencekids #scienceexperiment #homeschool #kidsactivities
