It’s a pizza! It’s a bagel! It’s a Pizza Bagel! Cut the bagel in half. Bagels are hard to cut so you might want an adult to help you. Spread a spoonful of tomato sauce on it. Don’t use too much sauce because it might get goopy. Sprinkle some shredded cheese over the sauce. Have an adult pop the bagel into a toaster oven or microwave until the cheese melts. Let it cool and take a big bite.
You can add stuff like mushrooms, basil, and oregano to put some pizzazz into your pizza. Make a pizza tortilla or pita pizza. Or invent your own. Bon appetit!
Many thanks to John K. of Womelsdorf, PA; Jon B. of Camden, AR, and Taquilla M. of Joliet, IL, for their yummy pizza recipes.

You can use a salt pendulum to make cool designs. What else do you think pendulums can be used for? Back in the 1500s, Galileo found that each swing of a pendulum takes the same amount of time, so a pendulum can be used as a clock. How do you think it works?
What You Need construction paper • tape • scissors • string • several sheets of black paper • salt
Roll and tape the construction paper into a cone shape. Make sure there’s a small hole at the tip of the cone. Cut three same-size pieces of string and tape them to the inside of the cone.Tie the three pieces of string into a knot.
Cut a piece of string and tape it across the top of a doorway. Cut a long piece of string and tie it to the middle of the string that’s across the doorway. Tie the cone’s strings to the long piece of string hanging from the doorway. Make sure the cone isn’t touching the floor. Put black paper on the floor across the doorway. Pinch the bottom of the cone together and pour salt into it. Lift the pendulum toward you and gently let it go. sent in by Andreas C. from Cincinnati, OH D
The swing of a pendulum is affected by gravity. Gravity is a force that pulls objects down toward the Earth’s center. When you pull the pendulum back, you give it energy. When you let it go, gravity pulls it down, but the pendulum has enough energy to keep swinging back and forth. What else can you find out about your salt pendulum? Think of a question you want answered, like what would happen if you changed the length or number of the strings? Be sure to predict what you think is going to happen.Then test your question and tell us about it at ZOOM, Box 350, Boston, MA 02134, or www.pbs.org/zoom.
