Adopt-An-Element - One of the favorite projects of the year! (T.(Trimpe) Tomm, Havana Junior High, Havana, IL)
Illinois Learning Standards: 12.C.3b

For this project, students are required to research an element, create an advertisement, and complete an element fact sheet. They may use the Internet (see Chemistry Links at the Kid Zone), CD-ROM's, encyclopedias, science books, or other reference sources. The advertisements are used to create a large periodic table on a wall outside my classroom.

The advertisement must be colorful, neat, and contain the required information - atomic number, atomic mass, symbol, element's name, advertising slogan, and cost. Students must create a slogan that is related to the their element's uses. Pictures related to the advertising slogan must be included. Advertisements may be done on a computer or hand written/drawn.

The fact sheet must be neat, written in blue/black ink, and contain all the information requested. Students are required to provide a list of sources (at least three) on the back of the fact sheet.

NOTE: For pricing information, visit the Chemicool and Los Alamos sites! I have also listed other periodic table sites for this project on the Chemistry links page of the Kid Zone.

Atoms Family (Lesson created by Kathleen Crawford, 1994)
Illinois Learning Standard: 12.C.3b

I use this lesson to introduce the fifth graders in my school to the basics of atomic structure. The members of the Atoms Family correspond to protons, neutrons, and electrons to help students remember their charges and locations in an atom. In addition, students learn the basics of electron configuration with a tour of Matterville. At the end of the lesson, students sing the Atoms Family song to the tune of the Adams Family. Need the Adams Family song? Visit this site and turn up the volume -!

Lesson Worksheets: Atoms Family - Atoms Family Worksheets (pdf) - Includes student worksheets and answer keys.

I've also created an Atoms Family Atomic Math Challenge (pdf) to help students determine the number of protons, neutrons, and electrons for each element.

Element Trading Cards (T.(Trimpe) Tomm, Havana Junior High, Havana, IL)
Illinois Learning Standards: 12.C.3b

I created this project for fifth grade students in my school. After completing the Atoms Family lesson and Atomic Math Challenge, students use their knowledge of the elements to create trading cards. Students are also challenged to find pictures that illustrate the various uses for the elements. The pdf download includes project directions as well as templates for the cards. The templates may be copied on cover stock or glued on 3" x 5" index cards. Our students create cards for 5 elements. The worksheet provided does not include such a requirement to allow you to modify the project to your classroom.

Periodic Table Basics (T.(Trimpe) Tomm, Havana Junior High, Havana, IL)
Illinois Learning Standards: 12.C.3b

I developed this lesson to build on the activity called Element Trading Cards (pdf) (see above) and allow my students to explore the periodic properties of the Periodic Table of Elements. Students complete fact cards on the first 18 elements. They use Internet sites or printed resources to find basic information (atomic number, atomic mass, and phase), melting and boiling points, physical and chemical properties, and common uses as well as draw Bohr diagrams and Lewis structures for each element. Students also color code the fact cards before cutting them apart and arranging according to atomic number. After students have created a "mini" periodic table on a large sheet of construction paper, they use the information they have collected to answer questions related to periods, families, and properties.

There are two versions available. Version 1 includes atomic number, atomic mass, number of subatomic particles, Bohr diagram, and Lewis Structure. Version 2 is the one I use with my 8th grade students and includes all of the items in Version 1 as well as phase (solid, liquid, gas), melting/boiling points, discovery information, properties, and common uses.

NOTE: I have listed periodic table sites for this project on the Chemistry links page of the Kid Zone.

Student Worksheets:
Version 1 (Basic) - Periodic Table Basics (pdf) - Includes all the worksheet and cards
Version 2 (Advanced) - Periodic Table Basics 2 (pdf) and Periodic Table Basics 2 cards (pdf)

Done with the lesson? Challenge your students with the Periodic Table Crossword Puzzle (pdf) . The Periodic Table Answer Key (pdf) is also available.

Bond with a Classmate (Gail Sanders, Monroe Middle School, Wheaton, IL)
Illinois Learning Standard: 12.C.3b

In this activity from Gail Sanders, a member of the MidLevel Science Teachers group in Northern Illinois, students are given a tag (or necklace) to wear with the symbol of an ion and its oxidation number. Positive ions are green and the negative ions are blue. The students are instructed to "bond" with other ions and keep a record of their bonds. Students had to work with their bonding partner to agree on and write a formula and name for the compound they formed. Once that was done, they could break the bond and find a different ion with which to bond. After 5 bonds, students switch tags with another student and start bonding again.

Balancing Act (T.(Trimpe) Tomm, Havana Junior High, Havana, IL)
IL Learning Standards: 12.C.3a

During this introductory lesson, students learn the concepts behind balancing chemical equations. I instruct my students to make a list of the atoms on each side of the equation to help them keep track of their progress. As they add coefficients, they increase the numbers for those atoms in their lists. The students can easily see if they have balanced each equation.

Playing with Polymers (T.(Trimpe) Tomm, Havana Junior High, Havana, IL)
Illinois Learning Standard: 12.C.3b

Explore the world of polymer chemistry with your students! My students loved learning about polymers and playing with their slime during a unit on petrochemicals. After the students make a batch of slime, they do a variety of tests and write their data/observations in a chart. After everyone has had a chance to test the slimes, I provide 3 samples of mystery slimes. The students do the tests with the mystery slimes to determine which ingredients were used to make each one.

Amazing Marshmallow's Lab (Boyle's Law) (T.(Trimpe) Tomm, Havana Junior High, Havana, IL)
Illinois Learning Standard: 12.C.3b

NOTE: A worksheet that combines Boyle's law and Charles' law is available - Gas Laws Lab (pdf)

Materials: Syringe & fresh small marshmallows

Procedure: To demonstrate Boyle’s Law, give students a syringe and 3 small marshmallows. Instruct them to place the marshmallows in the syringe and replace the plunger. Push the plunger as far down as possible without squashing the marshmallows. Place one finger on the end of the syringe and pull the plunger out to the end of the syringe. Observe the marshmallows. Students will notice that they get larger, or expand. As the plunger is pulled out, the volume of air inside the syringe increases causing a drop in pressure. This can be seen by the expansion of the marshmallow.

Next leave the plunger at the end of the syringe and place a finger on the other end. Push the plunger into the syringe and observe the marshmallows. Students will notice that they “shrink”. As the plunger is pushed into the syringe, the volume of air inside the syringe decreases, causing an increase in pressure. This can be seen by the compression, or shrinkage, of the marshmallows.

Bursting Balloons (Charles' Law) - Best done on a cold day! (T.(Trimpe) Tomm, Havana Junior High, Havana, IL)
Illinois Learning Standard: 12.C.3b

Materials: Helium balloons (mylar type) & tissue paper strips

Procedure: To demonstrate Charles’ Law, obtain two helium balloons of about the same size. Cut tissue paper into strips and wrap tightly around each balloon. Place one balloon in a warm spot, such as in a car on a warm day or near a heater. Leave for several minutes. Students should be able to observe the balloon increasing in size (or volume). If you are lucky, the tissue paper will tear! As the temperature of the gas increases, the volume also increases as the gas expands. A good reason not to leave helium balloons inside a car on a hot day! Place the other balloon in a cold spot, outside on a winter day or in a freezer. Leave for several minutes. Students should be able to observe the tissue paper becoming loose on the balloon - it may even fall off or slide off easily. As the temperature of the gas decreases, the volume also decreases. Many places that sell helium balloons in the winter time will warn you that your balloons may shrink when they are in the cold, but will return to normal size once they are back at room temperature. Charles’ Law should help explain this phenomenon.
