"This lesson will introduce DNA, genes, chromosomes, the chemicals that make up DNA, etc. After the basic information, students will do an experiment in which they will separate out DNA from peas. Knowing that DNA can be separated will give them a base of understanding for future lessons in biology, evolution, biotechnology, and health technology."

"This lesson will encourage students to examine the trade-offs involved in our use of energy, a topic they will likely revisit throughout their lives. This lesson is built around an interactive called Power Up! in which students choose how to power a city. They will have to choose between various energy sources, taking into account the trade-offs between cost and the environmental impact of each choice. Discussions before and after the game will examine the various options and what students may want to take into account when making their decisions."

What is it like to work as a paleontologist? In Activity 1, students listen to or read an interview with paleontologist Paul Sereno, a National Geographic Explorer-in-Residence, to learn about his passion for science and his discovery of SuperCroc in sub-Saharan Africa. In Activity 2, students join a dig with paleontologist Mike Everhart to learn what happens when a scientist in the field suddenly discovers fossil remains. In the Closing Activity, students create a story or conduct an interview and present or record their work for an imaginary radio program.

"This lesson uses the four modalities of reading (reading, writing, listening, and speaking) on a math word problem to bridge the gap between reading and math. After a read-aloud from the book Math Curse by Jon Scieszka and Lane Smith, students create their own word problems with answers. Students solve each other's problems. As they reread the word problems, fluency and comprehension increase. Finally, students use the skills they've learned creating word problems to complete a crossword puzzle. As students read the math concept words presented in the puzzle and write the correct answers, their reading and writing math vocabulary skills increase."
