The STEM Centre Collection
This is a series of resources created by STEM (Science, Technology, Engineering, and Mathematics) Learning to support the use of the BBC micro:bit in Science lessons.
Demonstrate the difference between acceleration and velocity with the BBC micro:bit
The difference between velocity (in metres per second) and acceleration (in metres per second squared) is key in science, but tricky to differentiate for students new to the concept.
Using a Micro:bit to detect acceleration rather than velocity gives students an opportunity to get first hand experience of the difference between these aspects of motion.
Astronaut Reaction Speed
Using the BBC micro:bit to measure changes in reaction speed
Human reaction speed is influenced by many factors in the environment, but also people’s reactions get slower as they get older. There's a difference in speed between subconscious and conscious reactions, but why?
In this activity we will be using a micro:bit device to measure reaction speeds, and investigate the effect of distraction on reaction speed.
Use the BBC micro:bit as a moisture monitor to grow perfect plants
Plants absorb large quantities of water from their environment. When plants are grown in artificial conditions it is important that water supply is regulated – too much and there is a risk of waterlogging; too little and growth rates will be restricted.
In this activity the micro:bit device is used as a moisture monitor for plants grown in containers.
Solids, Liquids and Gases
Program a BBC micro:bit to demonstrate the particles of matter
Using a particle model to explain the behaviour of matter is one of the Big Ideas of science education.
micro:bit devices can be programmed to simulate particle behaviour, and encourage an exploration of the effects of different conditions.
Just how good are we at discriminating small visual changes? Use the BBC micro:bit to find out
Visual perception is the ability of the brain to interpret incoming signals as information, which may then influence subsequent behaviour.
Using a micro:bit device to display different patterns on the LED display, we challenge the students to decide when there has been a change in pattern.
