You scratch my back and I’ll scratch yours! The phrase means doing something for someone and expecting a favor in return. Scientists showed animals can behave the same way. Norway rats are more likely to share food with rats who groomed their necks, and vice versa. It pays to be nice to each other!
Piiig Labs: Science Experiments for Kids
By Piiig Inc.
Piiig Labs is a digital playground for your child to explore science concepts in an old fashioned way, by putting together mini projects and learning through interaction and sometimes trial and error. By being “hands on” in the building process, kids get an inside look at how things work!
This is a great way to bring science into your home without the mess!
