Hi Eve! I actually run an afterschool Ecology Club for the 4th and 5th graders in my school! We just started it up in December, and this is the first club my school has ever had, so of course there are snags here and there.
Email me and we can talk more about it if you'd like!! firstname.lastname@example.org
I, along with our math teacher, am starting our school's first ever science and math club. I've been looking through competition sites along with sites that offer free kits and resources. I will post them as I get them all together. Maybe we could all find a way to collaborate on some projects. Maybe we could conduct similar challenges/investigations and then share our results.
