Element Card Project

Elements Project
To help you learn more about a particular element and familiarize yourself with the Periodic Table of the Elements, you will select one element and research it. We will do all the research during science classes by using the laptops in the classroom. You will have to do the art work at home. Each student will research a different element, so have a second and a third choice ready. The work is due on, or by, ____________________

You may use paints, markers, cut paper, stencils, downloaded pictures, word processed writing, whatever you want in putting the information on your card. Make sure you are neat!

Make use of the following sources to help you:
· Periodic Table of the Elements in the back of your agenda.
· An encyclopedia.
· books that contain information on the elements.
· the 5 web sites contained on Edline.


1. On the front side of the card, centered at the top, put the name of your element.__________

2. In the center of the card, in big letters, put the chemical symbol. ______

3. Then place the following information anywhere else on the front of the card:
· Atomic number _________
· Atomic mass _________
· State of matter _________
· Metal, Metalloid, or Nonmetal ____________
· Number of protons, electrons, and neutrons ____________
· Density _________
· Color _________


4. On the back of the card, put the following information:
* Date of discovery ___________
· Discoverer ____________
· Natural or synthetic (man made) ______________
· Origin of name _____________________________________
· Obtained from _______________________________________________
· Uses _______________________________________________________
· Other interesting facts about the element___________________________
· Picture/drawing of the element

Model of an Atom Project

Model of an Atom Project

I would like you to make a model of an atom. It should clearly show the major parts of an atom: the nucleus which is made up of protons and neutrons, and electrons which travel around the nucleus in a “cloud”. Your model should show that there is empty space between the nucleus and the electrons. Label each part or make a key. Refer to the “All About Atoms” handout you received and use the Periodic Table of the Elements in your agenda for information.

Use your imagination and creativity in selecting materials for this project. It can be presented as a free standing model, or suspended from something like a coat hanger, or mounted on a poster board. Feel free to use gumdrops, mini marshmallows, jelly beans, Styrofoam balls, paints, fabric, cut paper, etc. to represent the parts of an atom.

Your grade will be based on:

* Demonstrating a knowledge and understanding of the parts of the atom
* A neat and creative visual presentation
* The model is original. It presents a familiar topic (the parts of the atom) in an unfamiliar way.

Element of the day - Wednesday, May 13th

Who am I? Under regular conditions I am a dark-purple/dark-brown solid. I am primarily used in medicines to clean and disinfect wounds, photography, and in dyes. Table salt is often fortified with me. I am rare in the solar system and Earth's crust, however, compounds with me in them are very soluble in water and I am concentrated in seawater. I am necessary for the proper functioning of the thyroid gland in the human body.
