Sarah’s Bread and Humidity Experiment

Today was the science fair at our local elementary school, and Sarah shared what she learned about humidity and the science of baking bread. I brought my iPhone and interviewed her (using iPadio) at her exhibit in the cafeteria, and took several photos as well.

Kneading bread can be messy!

Humidity makes bread dough rise less

Bread rising under dry conditions gets bigger!

It took about three minutes to upload this almost-four minute audio podcast to iPadio with my iPhone over 3G from the school cafeteria.

It’s great to have opportunities to talk about what the students have learned as a result of DOING science. I really enjoyed the opportunity to not only visit with Sarah but also several of her classmates about their projects and learning.
