Topics Atoms Atomic Structure Isotope Symbols Atomic Nuclei Description Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas! Sample Learning Goals Use the number of protons, neutrons, and electrons to draw a model of the atom, identify the element, and determine the mass and charge.Predict how addition or subtraction of a proton, neutron, or electron will change the element, the charge, and the mass.Use the element name, mass, and charge to determine the number of protons, neutrons, and electrons.Define proton, neutron, electron, atom, and ion.Generate an isotopic symbol for an atom, given the number of protons, neutrons, and electrons.

Rock Candy - 3 Tips for Growing Sugar Crystals Video. Grow your own sugar crystals at home with this easy DIY chemistry experiment that's perfect for kids. Gather the few, simple ingredients and start experimenting today.See Transcript Hi, growing sugar crystals is a fun experiment, but it can be tough, so here are some tips to make sure your sugar crystals grow nice and big.
A Simple Recipe As with any crystal growing project, it is important to make sure your solution is at adequate saturation levels. A good recipe for a crystal-growing solution is three parts sugar and 1 part water. Cool Down Slowly The best and fastest growing sugar crystals can be achieved if the solution cools down very slowly. Use clothes pins or a bag clip to suspend a long wooden dowel inside the container. Once your solution is cool, you may even move it into the refrigerator to further help crystallization. Common Trouble Spots If crystallization is too heavy, pour the solution into a fresh, clean container, and move your dowel to that container. Batteries from Everyday Things.
