One of the most cool things about science projects for kids has to be the ease in which you can set up so many experiments, even at home! The one thing that all of these science activities have in common is that they can be easily done in a bag. How fun is that? Science in a bag is a great way to get the kiddos engaged in easy to understand science concepts.

Science Experiments In A Bag?

Can you do science in a bag? You bet! Is it hard? Nope!

What do you need to get started? How about a simple bag? It’s not the only supply used, but it will get kids asking what the next science in a bag experiment you have waiting for them is.

These science activities below work well with many age groups from preschool to elementary and beyond. Our activities have also been readily used with special needs groups in high school and young adult programs! More or less adult supervision depends on your kids’ abilities!

Using The Scientific Method With Kids

The scientific method is a process or method of research. A problem is identified, information about the problem is gathered, a hypothesis or question is formulated from the information, and the hypothesis is tested with an experiment to prove or disprove its validity.

Sounds heavy… What in the world does that mean?!? It means you don’t need to try and solve the world’s biggest science questions! The scientific method is all about studying and learning things right around you.

As children develop practices that involve creating, gathering data evaluating, analyzing, and communicating, they can apply these critical thinking skills to any situation.
