5 NO MOLD, NO BODY PARTS

No Mold, No Body Parts Bean and Ivy hadn't found a way to stop global warming, but Bean was willing to bet big money that no one else had either. She was famous for her good ideas and excellent fish prints. Ivy knew more about dinosaurs and prehistoric stuff than anyone in the whole

school. If they couldn't figure it out, who could? Take poor Zuzu, for instance. She was going to be an ice skater when she grew up. What did she know about science? Nothing. There was no way she had come up with a good science idea. But she had. Zuzu and Emma had decided to plant trees all over the school lawn. In fact, they hadn't just decided it, they had started doing it, during recess. They were digging holes everywhere. "Trees clean the air because they eat car exhaust and make oxygen," said Emma proudly. Bean had to admit that was pretty good. She and a bunch of kids from Ms. Aruba-Tate's class sat under the play structure and watched Emma and Zuzu dig holes. They had to dig fast so Rose the Yard Duty didn't catch them. Rose the Yard Duty didn't care about global warming.

Eric leaned over the rim of the slide and said, "I'm going to make a garbage robot." "You mean a robot made out of garbage?" asked Bean. "How's that going to fix global warming?" asked Ivy. She was reading a paper called "Science Fair Rules." "It's not a robot made out of garbage; it's a robot that attacks people who litter," Eric said. "I'll hide behind a corner, and when I see some

guy drop a cup or something, I'll press the button and this giant robot will come out and crush him. He'll scream—AAAAHHHH!— but too bad, he's dead." "Wow," said Bean. It seemed rude to ask Eric how he was going to make the robot. "Isn't the dead guy kind of like litter?" asked Drew. Eric disappeared down the slide. "It says no

mold and no body parts," said Ivy, reading. "Yuck. Mold is gross," said Bean. "I kind of like it," said Ivy. "But that still doesn't help us think of an idea." "You guys don't have an idea yet?" asked Vanessa. "No," said Ivy. "What's your idea?" asked Bean. Vanessa was either first or best at everything. She even

had a retainer already. It was very annoying. "Okay," began Vanessa, sounding like a teacher, "you know how Shayna said that the earth gets warmer when carbon dioxide gas holds the heat in? Well, guess what? People make carbon dioxide when they breathe out. So, if everyone breathed less, there would be less carbon dioxide, right?" Ivy and Bean nodded. "My idea is I'm going to make all my brothers and sisters hold their breath for fifteen minutes a day. I've got three brothers and two sisters. That's a lot of carbon dioxide." She looked at Bean and Ivy. "Good, huh?" "No one can hold their breath for fifteen minutes," said Ivy. "Not all at once," said Vanessa. "A minute at a time, fifteen times in the whole day. I bet I win the certificate." Bean bet so too, but she didn't say it. She said, "That remains to be seen," in a mysterious voice. But after Vanessa left, she turned to Ivy.
