Grade 4 Micro:bit Science

Sunlight Sensor

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.

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.
