Students determine how cloth gets its color by using vegetables such as beets, spinach, and onion skins to make dyes. In the seasons unit, students observe the dangers of too much sun and experiment with the suns light rays. Using a globe with stickers marking where they live, students in a dark classroom shine a flashlight on the stickers, slowly turning the globe from left to right to demonstrate how day and night occur. The unit on sounds investigates musical pitch and how sound travels. Eight glass bottles filled with different levels of water are used to demonstrate how sound is controlled by changing the column of air in each bottle.
Students tap each bottle, listen to the notes, and observe and discuss the different sounds.
The night sky unit assigns library research to find other names for the Big Dipper and the Little Dipper and discusses myths about the constellations. Student review questions and a word list are included. ENC does NOT distribute this resource.
