During this Unit, students will perform activities and conduct experiments that will introduce them to the concepts of using and making models and using symbols in the lab. Through their explorations, students will come to a better understanding that different types of models are used to help scientists observe and study objects that they can not easily see with their naked eye, results that are found in locations far from the lab, and objects that are too large to bring into the lab. In addition, they will have an opportunity to utilize scientific equipment as they perform their experiments.
As students complete this Unit, their experiments, observations, and participation in class discussion will aid them in better understanding that their natural curiosity, and declaration and recording of observations provide them with the procedures they need to conduct investigations of the biological and physical world and to share the findings of these experiments. In addition, this Unit will promote students’ awareness of the use of models and symbols in the lab as well as in their daily life, building continuity between laboratory investigations and real world applications and encouraging independent investigation.
