Solids, Liquids, Gases

Watch Study Jams: Solids, Liquids, Gases, then write in your copybook how they differ from each other.

Water

Watch Water: H2O Molecules Made Clear, then write in your copybook three things that you learned about water that you didn't know before.

Periodic Table

Why is the periodic table of elements arranged the way it is? Well...
elem_pertable2.png

The periods are the horizontal rows.
They indicate the number of orbitals (or shells) each element has.
The first row all have one shell, the second row all have two, etc.

The groups are the vertical rows.
They indicate how many valence electrons (or electrons in the outermost shell) each element has.
The first column has one valence electron, the second column has two, etc.
The elements in the eighth column are balanced and rarely combine with other elements.





The transition metals are the exception to this rule.
The common properties all metals share are that they are:
  • good conductors heat and electricity
  • very reactive (easily forms compounds and alloys)
  • malleable (ability to be shaped)
  • ductile (ability to form wire)
  • shiny
  • high melting points
  • high densities

Piece of the Periodic Table

Create your own piece of the periodic table on Print Shop, Word, or Open Office.

Instructions:
  • Find the information for the chemical assigned to you online at Environmental Chemistry.
  • Complete the information on the Information Gathering worksheet (extra copy: ) and use it to help you complete your Piece of the Periodic Table poster. Use the following guideline for you chemical's group: alkali metals (yellow), transition metals (green), nonmetals (orange), halogens (red), alkaline earth metals (brown), metalloids (purple), metals (blue), and noble gases (pink).
  • Notice that the name origin information and the properties information are written in complete sentences.
  • On the colored square that I will provide for you, place the following information as shown in the example below. The remaining information will be typed and glued to the back of the square.
  • You will also make an atomic model of your element in class using pipe cleaners and pony beads.

Example of Completed Form:

Example of Finished Project:
piece of periodic table A.jpg piece of periodic table B.jpg
Notice that the atomic weight is located in the top left corner and atomic number is in the top right corner. The location of each of the pieces of required information is essential.
This is the back side of the colored square. Notice that the remaining information about the element is typed in complete sentences with the student's name below it.

Things I will be checking for:
  • Content
  • Followed directions/example
  • Has at least 3 pictures for uses with brief description
  • Spelling/grammar
  • Atomic model has correct number of protons, neutrons, and electrons in the correct places.
