Bottle bottom turtles - too cute! Just need a turtle shape and the bottom of a 2-liter bottle! (for a big turtle) or you can use smaller bottles for smaller turtles. Make it fun and let the kids decorate their turtles with glitter and stickers too!!
Such simple items can be transformed into a cool activity that blends both science and art. If you have an empty water bottle, water, vegetable oil and food coloring, you can make this fascinating kid's activity! As a bonus, it also teaches kids about liquid density (and an explanation about that is included in this post!).
