Solar System Model

• Draw a circle measuring 8 inches in diameter on a sheet of thick cardboard. Do not remove the compass' spike and draw eight concentric circles, measuring 2, 2 1/2, 3, 3 1/2, 6, 6 1/2, 7 and 7 1/2 inches in diameter respectively -- these circles represent the planets' orbits. Cut out the 8-inch diameter circle. On a sheet of thin cardboard, design the eight planets of our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Don't design the planets' size to scale. Color the planets, cut them out and punch a hole near their circumference. Cut eight equal pieces of string, tie one end of each piece on a planet's hole and stick the other end on the planet's orbit using sticky tape.
  
  

Model of an Atom

• Draw a circle on a piece of paper measuring 2 inches in diameter to depict an atom's core. Keeping the compass' needle on the same position, design concentric circles to form rings representing the atom's energy levels. Each ring must be one-half-inch wide. Within each energy level, draw one one-third-inch diameter circle for each electron included. Write the number of protons and neutrons on the center circle with a black marker and color the core, energy levels and electrons -- use a uniform color for the electrons -- to complete the flat atomic model.
  
  

Paper Earrings

• Draw two 2-inch diameter circles on a sheet of thin cardboard. Color the earrings using markers. You can also decorate the earrings with glitter glue or cover them with acrylic gems. Punch a hole near the circumference of each circle to form a narrow section between the hole and the edge of the earring. Place the buckle of an earring hook around this narrow section to complete the paper earring craft.
  
  

Paper Clock

• Design a 6-inch diameter circle on a sheet of thick cardboard. Use the protractor to divide the 360-degree circle into 12 sectors measuring 30 degrees each. Teachers and parents can help children at this point. Cut out the full circle and place it on a flat surface, so that one sector faces upwards. Write "12" on the sector facing upwards and continue clockwise, adding numbers 1 to 11. Draw a 2-inch-long and a 1-inch-long arrow on a sheet of black construction paper. Cut them out and punch a hole on their nonpointed end. Also, punch a hole in the middle of the circle and attach the indicators on the clock using a brass fastener.
