I also put up my Scientific Method Posters. I made a ribbon banner (?) - ribbon sign (?)....not sure what to call it! Here's a photo:
I have this kit up on TPT for only ONE DOLLAR and it includes the smaller posters - 1/2 sheet (like I used to make this) and the full size - whole sheet posters. It also includes activities!
My class is coming together! I'll post some photos soon :)
