4-H STEM Lab is a good place to find hands-on STEM activities for students of all ages. Activities in the 4-H STEM Lab are organized according to topic and grade level. The topics are alternative energy, chemistry, electricity, engineering, and physics. As is often the case with resources like this, some of the suggested activities can be applied to multiple topics.
All of the activities listed in the 4-H STEM Lab contain materials lists and detailed directions for completion. Each activity page also includes a PDF that you can download to reference while completing the activity with your students. The PDF contains discussion questions that you can use to debrief after the activity is completed. For example, the Rubber Band Car activity PDF includes questions that ask students to consider other simple machines that could be powered by rubber bands.
Applications for Education
The 4-H STEM Lab's library of activities is still fairly small, but the activities that it does offer are well developed. I appreciate that the activities have possibilities for modification and extension based on your students' needs. The activities in the 4-H STEM Lab are a good fit for a summer or after-school enrichment program as well as being useful for traditional classroom settings.
