This one is a Jurassic KID Classic. Use cardboard or popsicle sticks to make a criss-cross extendable grabber, and then make it your own by adding paper dino jaws to the end. You will create a one-of-a-kind toy, while also learning about simple machines and cardboard engineering!
– Cardboard or thick popsicle sticks
– Pipecleaner, metal brads or paper clips
– Hole puncher or sharp pencil for making holes in cardboard
– Construction paper or paper plates
– Markers or colored pencils.
Tips and Thoughts
– Remember, this project has two parts: the mechanical grabber, and the dino head. You can do each individually, or put them together!
– If you are using cardboard, try scoring it first because cutting it into strips. This will make it easier to cut and avoid getting wrinkles in the cardboard, which make it weaker
– The video below used string to control the mechanical grabber Feel free to add this feature or leave it out! You can create a cool grabber mechanism with simply criss-crossing cardboard strips.
