Aiden calculated the speed of sound for each of the distances in his "Echo, Echo" lab. He used the formula: distance = 25 hand claps x distance to wall x 2 as his numerator, and divided it by the seconds taken for the 25 hand claps. He read a chart showing the speed of sound for different states of matter. He began the lab "Breaking Waves" by creating a data table and watching the lab video.
Aiden completed the lab "Echo, Echo" where he measured the distance and time of an echo at 30, 40 and 50 meters. The objective was to observe how distance affects rate of sound travel. He recorded his data in a table and answered the follow-up questions.
Jason completed his interactive calendar. He put together his daily sentence puzzle. He read and discussed his vocabulary words. He made a reindeer ornament.
Chris watched a video about how different types of animals protect their offspring and we discussed each: dolphins, orcas, wolf spiders, crocodiles, and toads. He read a passage describing how different types of animals protect their offspring. We discussed.
Aiden read about reflection, absorption and transmission. We discussed. He completed the Investigation "It's All Material" where he watched an animation of different room sizes made of different materials and how they affected sound waves. He wrote down his observations.
Libby completed her interactive calendar. She put together her daily sentence puzzle. She read and discussed her vocabulary words. She made a reindeer ornament.
