Tree Party • Autumn and Summer are outside painting pictures of trees. They notice differences in the color of the leaves. Autumn thinks that temperature may cause leaves to change color. The girls work together to see if she is correct. • IDENTIFY THE IV AND DV.
Morning Madness • Bailey does not like to get up in the mornings and never gets a chance to eat breakfast. Brittany loves to wake up early and never misses a meal.

Freaky Feet • Kat and Billy do not like other people’s feet. They begin to wonder if the sex of a human can be determined by only looking at their feet.

They decide to perform an experiment to see if they are correct. • IDENTIFY THE IV AND DV.
