Grade 4 Micro:bit Science
Sunlight Sensor
Light Level Sensor
4.9.7, 4.9.8 Opaque, translucent, transparent.
- Distinguish transparent materials from opaque materials by determining if light passes through them.
- Classify materials as transparent, partly transparent (translucent) or opaque.
In this program, students will test the opacity of different materials with a light sensor.
Students will create a reading variable for light level and have it display as a bar graph.
Test materials.
Recording and Graphing our Readings
To make an accurate record of our readings, we should record this information in a Google Sheet.
Math Specific Outcome 9
Represent and describe decimals (tenths and hundredths), concretely, pictorially and symbolically.
Soil Moisture Sensor
Are you growing plants in your classroom? Use this moisture sensor to let you know if your plants need water.
Totally dry soil will give a reading of 300-500. Damp soil will give a reading of up to 900. Anything above 900 is very wet.
See grade 7 for an advanced version
For more complex and accurate readings you purchase a sensor kit like this one: https://www.elecfreaks.com/estore/elecfreaks-micro-bit-tinker-kit.html,
