Investigation Backpack is a column by Bob Albrecht and Brian Hanna in The Oregon Mathematics Teacher (TOMT), the journal of the Oregon Council of Teachers of Mathematics (OCTM). In TOMT, we briefly describe intertwingled math and science investigations, and we post additional information at www.curriki.org (search key: investigation)

Earth 2007: People living in Earth habitats are switching from energy-gobbling incandescent light bulbs to energy-miserly compact fluorescent lamps (CFLs). Investigate the above claim. Is the claim true? If yes, why is this happening? Are there cost benefits? Are there environmental benefits? If yes, explain why. Compare the cost of lighting using incandescent bulbs and CFLs in 2007 and beyond. This unit points to Internet sources of information about incandescent light bulbs and CFLs.

Grab your favorite dictionary and play WordsWorth. As you play, you'll learn about permutations of words called reverses, palindromes, semordnilaps, and anagrams. Assign a letter score to each letter in the alphabet, a through z, as follows: a = 1, b = 2, c = 3, and so on, up to z = 26. The WordsWorth of a word is the sum of the letter scores of the word's letters. Most of the play in WordsWorth is thinking: knowing words, learning more words, and devising strategies for finding answers. People are well equipped to do this type of play. Some of the play is more mundane: looking up letter scores and adding them to get the WordsWorth of a word. First grade students might start with base-10 blocks as their WordsWorth calculator, and then move on to mental math and paper and pencil math as their addition skills improve by playing WordsWorth.

Investigation Backpack 03 was published in the December 2007 issue of The Oregon Mathematics Teacher (www.octm.org/TOMT.html). We suggested two investigations: Adventurer's Handbook intertwingles math, science, geography, and other disciplines that you might like to add. Piracy and Triangulation uses geometry, algebra, and map skills to hide or find a pirate's booty. This resource is part of the Investigation Backpack collection.

In 1993, the Center for Technology, Environment, and Communication (C-TEC) was a project-based alternative learning community at Piner High School in Santa Rosa, California. December 9 - 17, the last days of school in 1993, C-TEC cancelled regular classes and designed a Mission to Mars. Students were divided among the nine teachers and worked with their teachers, coaches, and mentors for the entire seven school days. Each teacher had an appropriate mix of sophomores, juniors, and seniors. December 17, 1993. It's a carnival! The school library and two other large rooms bustle with activity. There are oral presentations, video presentations, computer animation presentations, original Mars music playing, posters, a Mars art show, very large format children's books about life on Mars written in Spanish. C-TEC students, teachers, and many visitors mill around, participating, enjoying, being boggled. Mission accomplished! This resource is part of the Investigation Backpack collection.
