Grade 4 ELA Module 3A, Unit 2

student with teacher

In Unit 2 students read the extended science text Simple Machines: Forces in Action by Buffy Silverman (870L) to learn about simple machines while also examining the structure and text features of scientific writing. Several sections of this science text are structured as close-reading experiences, and students continue to learn to use context clues to determine the meaning of new words. They write routinely in order to explain how various simple machines work. Students also experience the scientific method in several simple experiments. They develop hypotheses, document steps in experiments, and synthesize their learning about how simple machines work in scientific conclusions. In the mid-unit assessment, students are asked to read an on-demand text about a simple machine, the screw, and answer text-dependent and multiple-choice questions. The end of unit assessment also has the students read a scientific text about a simple machine, the wedge, and answer text-dependent and multiple-choice questions. In addition, the students read an experiment, answer text-dependent questions, and conduct the experiment. They are asked to explain in writing their observations and conclude about wedges and their impact on work from the experiment.
