Gold Art Projects for Kids

Fruit Loop Rainbow Collage

Give each student a large piece of white paper. Add food coloring to paint to create the same colors as the Os in a box of Fruit Loop cereal. Paint a rainbow on the paper with clue and let the children sort through the cereal and match the Fruit Loops the glue and create a rainbow of cereal.

Rainbow Necklaces

Dye or spray paint macaroni in the colors of the rainbow: red, orange, yellow, green, blue, and purple. Let students string the macaroni onto yarn to create colorful, rainbow colored necklaces. You can also use Fruit Loops for a less permanent necklace.

Rainbow Wind Sock

Give each student a piece of light blue paper. Let them cut or tear out cloud shapes from white paper to glue to the blue paper. Then give each student strips of crepe paper in red, orange, yellow, green, blue, and purple and let them tape or glue the strips of paper to one of the long ends of the blue paper. When finished, staple the short ends of the blue paper together to create a tube. Staple a piece of yarn to one end to create a wind sock.

What are Rainbows Made of?

Demonstrate how rainbows are made out of fractured light beams by holding a prism in a sunny window and creating a rainbow out of light. Explain that sunlight shining through raindrops is what creates rainbows in the sky. Let students take turns playing with the prisms.

Rainbow Color Mixing

Fill three sections of a white ice cube tray with water and dye the water red, yellow, and blue. Give each student an eye dropper or pipette to mix the colors in the empty trays. Have them figure out what colors they need to mix to make the other colors of the rainbow: orange, green, and purple.

Rainbow Snack Kabobs

For a fun rainbow snack, give each student a red strawberry, a piece of orange, a yellow piece of pineapple, a green piece of honeydew melon, a large blueberry, a purple grape, and a kebob stick. Help them put their fruit on the kabob stick in the color order of the rainbow.

Recycled Rainbow Color Crayons

Preheat oven to 300 degrees. Let students choose several old crayons, peel the paper off of them, and break them into pieces. Have each student put his or her pieces in one section of a muffin tin that has been lined with foil sprayed with vegetable spray. Bake until crayons are completely melted and them cool until the crayons are hardened, several hours or overnight. Remove the new crayons and let students color with their new rainbow colored pan.
