Identify a problem, test a possible solution to the problem, and communicate the results. Use instruments to extend the senses. Learning can come from careful observation and experiments. By the end of fourth grade, students will develop the abilities needed to do scientific inquiry. Students write a hypothesis about the effect of viscosity on the amount of time it takes a marble to fall through a liquid and design a controlled experiment to test their hypothesis.
Students perform their experiment, record data, and state a conclusion.
Students will complete the Process Skills blackline master on Lab Manual pages 111-112 as they do the activity. Students will observe a hand bell by using the senses of sight, smell, and hearing, but without touching or tasting. Students will records their observations. Students then ring the bell and record their observations. Finally, students compare the tone and dimensions of their partner's hand bell with that of their own.
