Maps: Completed, Evaluated, Appreciated
Last week Fourth graders took time to evaluate each Washington State Map. When students evaluate another person’s work they better understand the importance of looking at grading criteria before, during and in the completion of an assignment. I have just completed my own evaluations so all maps can go home this week. I am very aware that no score can adequately represent the time and work each map represents. Thank you for all your work. This week fourth graders reflect on their map-making experience – source for insight.
Last week fourth graders observed how sound travels through three states of matter: solid, liquid and gas. They also explored amplification. We used a tuning fork, cylinder and megaphone to gather and direct sound through air. A stethoscope and a tub of water helped us explore sound underwater. Finally, tissue and a wooden dowel along with our classroom desks allowed us to receive sound traveling through solids. If you have a chance to swim in a pool, take a few minutes to find out a little more about how sound travels underwater and about underwater hearing. With your head below water, have your friend say words that sound the same, like “top,” “pop,” “mop,” “cot,” and “pot.” How does it sound? What do you think is going on?
Check out these online videos that help explain the physics of sound:
