Have an Outdoor Cook-out. Perhaps it could be at a local park, and families could be invited to attend after the girls have prepared the food.

Go swimming, or have a big water fight at a park. Visit an aquatic center or community pool.

Make fire starters for Father’s Day gifts. Fill empty egg cartons with sawdust, pour melted wax over to bind.

Have a Court of Awards ceremony. Invite your families. Have a Pot-Luck dinner or dessert.

Have a backwards meeting. Have everybody dress in backwards clothes. Do everything in the opposite order that you usually do them.

Make a solar cooker. You can make three different kinds and have a marshmallow-roasting contest to see which one works fastest. For the first one, all you need to do is to line the inside of a large mixing bowl with aluminum foil, shiny-side up. You may want to try two or three bowls to see which works best. For the second cooker, you need a piece of cardboard thin enough to bend. (The backing of a legal pad works well.) Cover one side of the cardboard with aluminum foil, shiny-side up. Then bend the cardboard into a semi-circle, with the foil on the inside of the curve. Use string to tie the cardboard in this position. The is easier to do if you wrap the string around twice and tie the knot in back. Solar cooker No. 3 is made with an empty cylindrical oatmeal box. Cut a long window in the side of the box. Line the inside with aluminum foil, shiny-side out. Now it’s cook-out time! It is important to remind the girls of these rules: Never look directly into the sun. Be careful with the concentrated spots of sunlight your solar cooker will gather. It can burn your skin! Also, don’t look directly at any glaring or bright spot on your solar cooker. Set your three cookers in a bright sunny spot. Try to aim them so that the sun is shining directly on the foil. Put a marshmallow on the end of a long stick, and the race is on! The trick to toasting the marshmallows is to find out where the reflected sun’s rays are crisscrossing. For each cooker, this spot will be in a different place.

Make a sculpture: Set a plastic bag in a bowl. Pour 1 cup of water in the bag. Slowly sprinkle 2 1/2 cups of Plaster of Paris into the water. Hold the top of the bag closed with one of your hands. Squish the bag with your other hand until all the lumps of Plaster of Paris are mixed with water. Squeeze out all the air in the bag. Use a twist tie to close the bag. Put the bag on a smooth, flat surface. The mixture will look runny and won’t hold a shape. Suddenly, it will begin to harden and feel warm. Quickly form your sculpture. Pull the mixture into shapes. Or, press the bag around a bowl or other object to shape the mixture. As you work, keep pulling the plastic bag up, so it won’t get stuck in the plaster. Let your finished sculpture dry for 30 minutes. Then carefully cut the plastic bag. Strip it away from your sculpture. Use a plastic knife to draw criss-cross lines or other designs on your sculpture. After 24 hours, you can decorate your sculpture. If you want, you can smooth it with fine sandpaper.

Go to a local pond and watch the surface carefully. You may see insects on the surface or around plants on the water’s edge. Sweep a pond net quickly just under the surface of the water and lift it up. Empty into a tray and watch carefully. After awhile, you may see some movement. Use a magnifying glass to examine the life and record the different types of creatures. Be sure to return the creatures to the pond as soon as possible. Take plaster casts of any animal prints you may see at the water’s edge. Fill small jars with half sand and half water from the water’s edge. Leave 1/2” of air space at the top. Give the jars to the girls to shake. Watch the sand as it settles. Compare the various jars of sand to see if they are the same or different. Compare sand collected in different locations. Try various types of jars. Add objects to the sand to change the pattern.

Try some stargazing.

Learn about clouds. Go outside, lay on your back and study cloud formations. Use your imagination and make up stories to fit the shapes of different clouds.

Have a “movie appreciation sleep-over”. Be sure to include old and new, musicals, comedies, mysteries, drama, etc. Be movie critics. Don’t forget lots of popcorn!

Practice photography. Let the girls use the disposable cameras and take pictures of nature.  Arrange into scrapbooks. Before beginning, have someone who is a photographer (professional or hobbyist) talk with the girls about composition, distance, light, etc.
Make pinhole cameras and take some pictures.

Make a bug zoo. Needed are two 6 oz. tuna or cat food cans, a piece of 6”x12” piece of screen wire (like window screen), three round head brass paper fasteners, a stick or branch, plaster of Paris and a pop bottle cap. Roll the screen wire into a tube as big around as the inside of the can. Fasten screen together with paper fasteners : one in the middle, and the others equidistant from the edge to the middle. Mix enough plaster to fill the can 3/4 full, then press the screen down into the wet plaster. While the plaster is still wet, press a small stick or branch and the bottle cap (open side up for water) into the plaster. The lid (second can) sets on top so it can be easily removed and replaced for entrance and exit of the critters. Remind the girls that when they capture an insect alive and keep it for observation, they must remember to feed it and give it water. After a little while, it should be released.

Make tin can ice cream. Place a 3 3/4 oz. pkg. instant pudding mix (any flavor - this will be the flavor ice cream you get!) and two 6 oz. cans evaporated milk in a one pound coffee can. Stir well. Add enough regular milk to fill can 3/4 full, mix well. Cover with lid and tape securely with duct tape. Place one pound can in a three pound can. Add layers of crushed ice and rock salt, making sure to surround smaller can with ice and salt on all sides. Put lid on larger can. Tape securely. Form two lines and roll the can back and forth on table or ground for fifteen or twenty minutes. Carefully un-tape large can and remove small can. Be sure to wipe off all salt before removing lid. If ice cream is not set, push down from sides, re-tape and place back in large can with ice and salt for five more minutes. One makes enough for 5-6 girls.

Have an ice cream eating contest. Tie spoons together with a 6” piece of string. Partners have to eat together. First team done wins!

Do some leaf prints. For a shirt, paint leaves with acrylic paint and gently press onto shirt. Lift off gently. Acrylic paint will not wash out of clothing, so be careful!

Have a roller skating/blading party. Either go to a rink or use a playground.
