The Databot Game fired up an intense new challenge recently. We were in Salt Lake City at the NSTA Regional Conference attended by thousands of science educators. The Databot Game is a fun approach to exploring the invisible world of data that surrounds us. It facilitates learning about sensor data in a way that naturally engages students in learning core science concepts addressed by databot’s on-board sensors. Databot’s sensors were specifically designed to provide a plethora of options for educators to teach Earth Science, Physics, Chemistry, Life Science, and even Environmental Science.

Bubbles in tubes offer many advantages over spheres on ramps for velocity and acceleration experiments:
- The bubble stays in the tube! There are no escaped marbles to chase down.
- The bubble moves more slowly than a marble, permitting more accurate determination of elapsed time.
- Results are highly reproducible.
- Many data points can be collected in a short period of time.
A Speed of the Bubble Apparatus to hold and protect the tube is easy to construct from scrap and/or inexpensive materials. It enables even very young students to obtain highly reproducible data quickly. It also protects the tubes from being damaged if dropped or bumped. Plans and suggested materials are included in this blog. The following experiment is one I use with the elementary students in our after school science club. Read the rest of this entry »
