Sensing data…

The children brought their investigations on Costa Rica´s climate and topography… we discuss the different conditions that affect the weather and how we can measure them. We started a project using the Gogoboards to measure temperature and light and to explore things that affect weather conditions.

We program the Gogoboards to record data using different sensors, and we upload the data on a Microworlds project. During the first activity we used a light sensor. The children recorded data for five minutes (a data point every 30 seconds), and we used a simple linear graph to annotate the recordings. They repeated the experience with different sensors and talk about the readings. We discuss the readings and how the different sensors work and how they can be used for different things.

The children wanted to investigate the temperature in their houses, so they programmed their Gogoboards to record light and temperature reading over night. They decided to run the same experiment to compare their experiments. We will talk about the data they collected tomorrow.

The issue of different data representations came up today, so we are talking about those tomorrow... more to come!
