Here is a fun and very easy art project for any age and for anytime of the year. You can vary the subject matter to feature anything you like (flowers, boats, cats, dinosaurs, etc.).
The supply list is simple: tissue paper and some liquid starch.
The challenge here is to have the children think visually, not worry about creating a perfect dragon and basically, have fun with the cool textures of tissue paper and the starch.
To start, tear a piece of tissue paper in the shape of a dragon head. Of course, everyone's shape will look different. Now, dip a paint brush into a bowl of liquid starch (yes, the kind you find in the detergent aisle of the grocery store) and apply a little bit to the paper where you intend to place the head. Set down the "head" and brush again with the starch. Continue along this route with the body, tail, legs, spikes, etc. Smooth down any dry or rough patches with more starch.
Once dry, you can place the artwork between two heavy books to flatten out the piece.
If you want, you can draw a black line around the figure to create a more distinct picture. You can even add details like eyes or scales.
