Give each student a bingo card with the abbreviation of the elements on them. Include a center free space. Call out the full names of the elements and write these on the board. The students must cover the abbreviation that matches the element's full name if they have it on their card. Just as with regular bingo, the first person to have a row fully covered calls out, ''Bingo'', but they must prove that they have the correct abbreviations to the elements you called out.
Place the students in teams for a scavenger hunt of items from the periodic table. Over the next few days, have the students find these items, bringing in as many common household items as they can; this should be items that are either pure or chemically combined elements. Provide the students with guidelines that inform them not to bring any substances considered illegal, flammable or otherwise dangerous, in their current form. Students may bring in items such as water to represent hydrogen, an aluminum pot to represent aluminum, table salt for chlorine, and a gold necklace for gold. The team that brings in the greatest number of correct examples of elements wins a prize. You can also have each group give a short presentation on their findings.
Divide the class into two teams and create a jeopardy board with categories based on the periodic table such as "Household Elements", "Element Abbreviations", and "Compound Elements". The questions should be appropriate to what they have learned so far. You can start off the game by picking the first question. The class must consult with their team, then a chosen team member buzzes in if they think they have the correct answer. If they do not, the other team gets a chance to answer the question and get the points. Include one or two daily doubles with tougher questions.
Assign an element to each student and tell the students they must market it to the masses, letting everyone know why their element is the best and why they should buy it. Have the children come up with a brochure which should have information about the the origins and discovery of the element, its uses and why its important. On the day of presentation, have the students dress up and "pitch" their element to the class.
