Veronika the cow uses a brush as a tool to scratch herself, revealing rare problem-solving skills and expanding what we know of tool use in animals.

Veronika, a cow living in an idyllic mountain village in the Austrian countryside, has spent years perfecting the art of scratching herself with sticks, rakes, and deck brushes. Now that scientists have discovered her, she has the distinction of the first cow known to use tools.

The unexpected observation of a cow using a broom to scratch herself isn't necessarily surprising, but it expands our knowledge about the biodiversity of tooling.

Students will apply their knowledge of physical science concepts to create a lunar lander game using Scratch. They will use Vernier force and acceleration sensors to understand forces and integrate sensor data into their game, enhancing realism and ...
