About a month ago a colleague told me about a website called Mystery Science. The site has great lessons with hands-on activities. You can search for topics or browse by grade level. Best of all, it’s free!
Earlier this week I used a lesson with my students to explore how sound travels. They used paper cups, string, and paperclips to make telephones. Students “talked” through the phones to learn about sound waves. It was an engaging, hands-on activity that really helped them understand how sound travels.
If you teach elementary school, you should definitely check out this website.
