Get two black balloons. Inflate one of the balloons fully; inflate the second only half way. Duct tape the tied ends of the balloons together so they form the body of a bat. Instruct the child to cut out two oval eyes and two triangular fangs from white construction paper. Have her cut two small pupils to sit in the center of the bat's eyes, two triangular ears and a pair of wings out of black construction paper. Assist her in attaching these features to the body of the bat with black duct tape. Use the tape to attach a ribbon where the balloons meet. Attach the ribbon's other end where you'd like the vampire bat to hang.
After your kindergartner chooses a balloon, inflate it. Direct the child to form a face by decorating the balloon with markers or stickers. Cut out a base shape to resemble a pair of feet from construction paper. Ask the child to color and decorate these feet with markers. Place a small hole in the center of the feet-shaped base, and thread the tied end of the inflated balloon through the hole. If the balloon does not stand up correctly, tape a coin to the bottom of the feet to balance it.
Cut up several colored drinking straws into 1-inch lengths. Direct your kindergartner to thread these straws over eight separate pieces of string. Tie a bead at the end of each string to prevent the straws from falling off. Next, inflate a balloon. Assist the child in taping the strings around the balloon to act as arms of the octopus. He can then draw a face on the balloon to complete this fun octopus.
Blow up a balloon to stretch it, then allow it to deflate. Attach a funnel to the balloon neck, then allow your child to pour in dry lentils until the balloon is completely full. Tie the neck of the balloon in a knot, then cut off any excess. Get a second deflated balloon. Cut off the neck completely and throw this away--making sure to save the bottom half. Using the bottom half of the second balloon, stretch it over the lentil-filled balloon. Make sure you are covering the knot you tied on the first balloon. Add more layers for extra security.
Place two long pieces of ribbon crosswise on a flat surface. Tie a knot where they meet. As your child to decorate a paper cup with paints or markers. It will act as the hot-air balloon's basket. Pierce four equidistant holes around the paper cup's rim. Thread the four ribbon ends through these holes and fasten with knots. Position an inflated balloon inside the ribbons. Glue the ribbons to the balloon surface to fasten.
