Science Activities for Kids of All Ages

Kids are super curious and science is the perfect way to entertain them while learning and having a really good time. These science activities are great for kids of all ages:

Science Activities For Toddlers

A lot of supervision and direction is needed from the adult and the toddler science activity is more about what will happen and less about why it did.

Science Activities For Preschoolers

Again, a lot of supervision and direction is needed from the adult and the preschool science activity is about what will happen and then playing with what did happen. Kids at this age may start to question how.

Science Activities For Kindergartners

Supervision is necessary, but the direction of what is happening is shifted more to the child. Let the child explore (safely) within the perimeters of the science activity and talk about what is happening and why.

Science Activities For Elementary School and Beyond

These activities make great inclusions into science lesson plans and the basis for science projects. Everything in science can be just the start of the exploration of knowledge!
