Oxygen 3d Model Project. You can make a 3d model of oxygen atoms by using the colored styrofoam balls which are held together with some toothpicks or straws. The model should be triangular when you are done so keep this in mind when pricking the balls.
Prick two of the three balls with a toothpick making a small hole. Glue both colored craft balls into a ball alternating between the protons and neutrons as you glue this will resemble the nucleus 1 x research sourcestep 3 cut out the cardstock. Push the oxygen atom label into the top of the largest sphere.
Prick the third ball twice making one hole on each side of the ball.
Prick two of the three balls with a toothpick making a small hole. You will need glue scissors cardstock string 40 large craft balls 20 of one color for the protons and the other 20 for the neutrons that s a different color and 20 small craft balls for the electrons step 2 glue the protons and neutrons together.
