How-to 1. Find a print in the mud or make your own by press- ing pinecones, sticks or other object into the mud and then removing them (you should be able to clearly see the print). Remind the children not to step on the prints they’ve found or made.
2. Remove debris (leaves etc) from your print area. 3. To make a hanging-hole in your plaster-print, stick the piece of straw into the mud, so it is standing upright, just above your print (when smoothing your plaster-mix over your print, be sure that it surrounds the straw).
4. When your print is made, make your plaster-mix in your mixing container. Mix the plaster and water together. The consistency should be like toothpaste. Add plaster/ water as needed.
5. Pour the plaster-mix over your print and smoothen it with the back of a spoon, remembering to surround the straw (but do not cover it). The plaster should be thick enough so that you cannot see the mud through the plaster (ide- ally, about half a centimeter).
6. Let the plaster harden - do not disturb it for 40-60 min- utes (time depends on the consistency of both the mud and the plaster). Plaster prints should be handled gently for min. 2 hours after being made. After 2-4 hours, they are fully hardened.
7. After the print has fully hardened, use the toothbrush (or other similar soft brush) to gently remove the remaining dry mud. If you plan to paint your print, thin water paints, applied
lightly to pieces of sponge and dabbed gently onto the plas- ter print, will give beautiful results.

From Egg to Frog Go on a pond adventure and learn about a frog’s lifecycle with this curiosity-driven activity. Can you find the different stages of a frog’s life and the resources it needs for survival? Find the illustrated clues and put them in order, from egg to frog. Then ask yourself what a frog needs in order to survive during each stage of its life. Important notes: wash sunscreen/bug-repellant off your
hands before going on an adventure that may include han- dling amphibians. Walk gently. Catch-and-release rule for frogs and tadpoles is 2 minutes. Do not disturb frog eggs. Leave-no-trace.
What you need • A marshy area or a pond • Rubber boots • Net and bucket • Camera
