This column discusses resources and science topics related to students in grades preK to 2. This month’s issue provides sound explorations.
This article describes the importance of child exploration. The author makes it clear that even from a young age, children are engaged and enjoy investigating through exploration. When children get the opportunity to explore on their own, they are more likely to understand the material because they can make connections. I enjoyed how the article was linked to one of the NGSS standards in which students must, "Plan and conduct investigations to
provide evidence that vibrating materials
can make sound and that sound
can make materials vibrate”. The article gave a great example of an activity that can be done following this standard. I liked how the author emphasized the importance of the learning component by the teacher but also the exploration as well. I found the questions the teacher would ask for reflection to be interesting to assess the student's knowledge on the topic. Overall, I found this article to be extremely helpful in preparing my own science lesson.
This article was extremely helpful in providing ideas on how to turn the specific standard on sound and vibration into a lesson that is compatible for first graders. The article suggests using a musical instrument such as a triangle for students to understand how the sound is created by the motion of the vibration that occurs when we strike the triangle. This would be an activity that would work well for first grade students because it is hands on and they are able to complete it on their own. I also like the idea presented here that has students draw what they are seeing and also answer open-ended questions. This is a helpful way to assess what students are taking in from the information we are teaching them.
Young children cannot understand the technicalities behind sound, but they can understand vibration and pitch (low and high sounds). This article gives a very detailed lesson about sound using simple materials of rubber bands and milk cartons.
