Students will complete a series of experiments designed on the process skills. By the end of fourth grade, students will develop the abilities needed to do scientific inquiry.
Students blow into a straw to observe the pitch of the sound produced.
Then students form a hypothesis about how the length of the straw will affect the pitch of the sound. Students test their hypotheses Students will observe a pencil using the senses of sight, touch, hearing, and smell. Students will record their observations, then observe the pencil after changes take place. Students then use a hand lens and a tape measure to make further observations. Students collect data on the hair color and eye color of their classmates.
