Note: If your bug doesn't light up, turn the LED around and insert the long lead into the other side of the body. Turn on the battery pack and watch the bug glow!.Stick the red wire into the side with the positive LED lead put the black wire into the other. Insert the batteries into the battery pack.Remember which side has the positive lead. Pull the leads apart, and stick one end into each side of the body. The longer one is the positive lead, and the shorter one is the negative. (Make sure the side pieces don't touch each other or the bug won't light up.) Add eyes and antennae as you like. From Play-Doh, make the head and two separate, oblong sides place them on the paper base.Cut an oval cardstock base for the bug and two heart-shaped wings.(Find the bulb and battery pack wherever electrical supplies are sold.) And never touch battery-pack wires to each other or attach LEDs straight to the battery-pack wires. You're working with electricity, after all. There are a few extra rules for this activity, though: Adult supervision and safety glasses are required. Who knew that playdough could conduct electricity? In this STEM activity from Anne Carey of Left Brain Craft Brain, kids will create a simple closed circuit to make their bug glow. Place it across the top of the box just in front of the arm secure it in place by wrapping a large rubber band around one end of the pencil, under the box, and up and around the other end. Create a "stopper" for the catapult arm with the third pencil.Thread the tail of the slipknot (from Step 4) through the remaining hole, and knot a paper clip around the end to hold it in place. Place the ends of the horizontal pencil in the side holes.Wrap another rubber band around the shorter end of the arm using a slipknot.Tape or glue a small jar lid to the longer end of the arm as shown.Assemble the catapult arm: Join 2 pencils together perpendicularly to make an inverted lowercase t secure them with rubber bands.Punch a third hole on the opposite short side it should be centered and near the bottom. The holes should be large enough for a pencil to rotate easily. Punch a hole in a long side of the box, 3 inches from a short side.Play around with the position of the stopper to get the maximum angle and distance for your launch-and have fun with colors and decorations. This simple machine uses stored energy (the tension in the rubber bands) to release a projectile (called the payload). Note: If after some use, one of the straws cracks, simply replace it with a new one. Bend the flexible straw to aim and place the rocket straw over the end. To launch the rocket, inflate the pouch by blowing into the flexible straw.Add this to the top to seal the straw completely. Add washi tape to decorate the straw if desired. Tape one half-fin perpendicularly to each full fin as shown.Tape the full fins on each side of the straw.Make three trapezoids from cardstock, in the following dimensions: 3 inches (base) x 1 inch (height) x 3/4 inches (top).Insert the pointed end of the straw into the straw hole of the juice pouch.
