Big Science for Little Hands

Professional Development Workshops

Big Science for Little Hands is Science World’s professional-development workshop series for Early Childhood Educators. We provide two-hour workshops where participants try out a variety of fun, hands-on science activities suitable for children aged 3-5. We also spend time with the STEAM (science, technology, engineering, art & design, and math) concepts behind each activity and discussing ways to encourage scientific literacy in young children.

There are six workshops to choose from. Each one introduces two of our Big Science for Little Hands themes and includes small and large-group activities that can be adapted to any childcare setting.


Amazing Me/Super Sleuths

Explore how amazing the human body is, through a variety of hands-on — and toes-on — activities; discover how doing science is like being a detective.

Bubble & Fizz/Mysterious Mixtures

Conduct experiments with a variety of everyday kitchen ingredients, exploring concepts such as dissolving, mixtures, and separating, and how they are connected to chemistry.

Gadgets & Contraptions/The Air up There

Explore a variety of simple machines and how they work to make life easier; investigate things that fly and float and how they are connected to properties of air.

Rockin' Rocks/Salt & Fresh Water

Investigate the properties of rocks and salt and fresh water and how they are connected to the natural world!

Sticky Stuff/Wet & Dry

Why is glue sticky, and what happens when it dries? How is Velcro connected to nature? What do we mean by wet and dry? Investigate these questions with lots of hands-on activities.

Structures/Balance This

Lots of science takes place when building with blocks, but in this workshop, we use non- traditional building materials to explore gravity, structure, balance, and stability.
