Grade 8 Micro:bit

Health Monitoring Systems

BK3 Interpret the healthy function of human body systems, and illustrate ways the body reacts to internal and external stimuli BK3.4 describe changes in body functions in response to changing conditions 

Micro:bit Being Active Design Challenge

Fitness friend: create a simple wearable device to give regular reminders to do some exercise.

Heart rate monitor: learn how to measure their heart rate and create a prototype of a heart rate monitor.

 Walking for water: learn how some children have a daily walk for water and create a step counter to track their steps.

Advanced challenge:

Can you combine 2 or 3 of the devices into one wearable system to make your own wearable fitness device like a FitBit?

1.  Fitness Friend (Fitness tracker)

Have you ever wondered how a Fitbit works?  Make your own reminder to get active!

Learn how to measure your heart rate and make your own heart rate monitor  

See other examples of a more advanced heart rate monitor HERE

3.  Walking For Water - Step Counter

What if you had to walk to get water every day?   Get some perspective and measure your fitness by creating a step counter to track your own steps.  Also see how to build a modified step counter here

Light Sensors

CK1 Investigate the nature of light and vision; and describe the role of invention, explanation and inquiry in developing our current knowledge 

1.  Getting started

Have a look at the grade 4 science to see how to build a light level sensor

Advanced challenge:

Use the grade 5 & 9 lessons to make a circuit and light up a bulb and use your light sensors!

Simple Machines - Make your own machines and devices

DK1 - Illustrate the development of science and technology by describing, comparing and interpreting mechanical devices that have been improved over time DK2 - Analyze machines by describing the structures and functions of the overall system, the subsystems and the component parts DK4 - Analyze the social and environmental contexts of science and technology, as they apply to the development of mechanical devices 

Water Quality Monitoring

EK3 - Analyze factors affecting productivity and species distribution in marine and freshwater environments EK4 - Analyze human impacts on aquatic systems; and identify the roles of science and technology in addressing related questions, problems and issues
