1-LS1-1. Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs
In this experiment, students carried out an investigation to determine the relationship between the shape of different bird beaks and the food each bird eats:
1-LS1-2. Read texts and use media to determine patterns in behavior of parents and offspring that help offspring survive.
