Collect data with sensors for classroom exploration.
Involving students in the first step of the data collection process promotes engagement and interest.
It’s hard to collect accurate data in the real world. Students must learn to be aware of different variables that impact readings and to harness their critical thinking skills to troubleshoot often.
Raspberry Pi is a small, microcomputer processor with an average cost of $25-$35. This simplistic device can be outfitted with different sensors, including those that measure temperature, moisture, humidity, and so much more.
Without a keyboard or monitor, the Raspberry Pi can be set up in any location in a classroom and take measurements of sensor data at requested intervals.
Once collected, data can be downloaded and used for analysis.
Hawkes is using these devices to set up several experiments to provide a live data feed for free use, and you can too!
Here are 3 ideas for experiments that we have in the works using Raspberry Pi:
1. Bamboo growth
Follow how quickly different bamboo plants are growing and what impacts their growth. You can also check out the cool sensor data PiPlanter is collecting, including soil humidity and ambient light, to create a clever irrigation device!
2. Air quality control
Track carbon monoxide emissions and see how the readings change as distance to humans varies.
Assess temperature in different locations of the room. Watch out for variables such as air conditioning drafts, sunlight, and proximity to people and computers.
