Binary Bracelets
Binary code relies entirely on just these two numbers to represent all data.
What are 0 and 1?
The acronym "SDG" stands for this phrase.
What are Sustainable Development Goals?
In Tinkercad Circuits, this component restricts the flow of electricity so your LED doesn't blow up.
What is a resistor?
This is the plastic board with a grid of pegs where you snap all your pieces together.
What is the base grid?
The brain of the Micro:bit has a 5x5 grid made up of 25 of these tiny lights.
What are LEDs?
A single 0 or 1 in binary is known by this tiny three-letter name.
What is a bit?
This global organization, made up of countries from all over the world, created the SDGs in 2015.
What is the United Nations (or UN)?
Electrical resistance is measured in this unit, symbolized by the Greek letter Omega.
What are Ohms?
This component provides the power, or the "push," to make electricity flow through your Snap Circuit.
What is the battery (or battery pack)?
In VEX Robotics, you connect these to the central Brain to make your robot's wheels spin and drive.
What are motors?
In a binary bracelet, you string together this exact number of beads to represent a single letter of the alphabet.
What is 8 (or a byte)?
SDG 13 focuses on taking urgent action to combat this global environmental issue.
What is Climate Change?
The colorful painted bands on a physical resistor tell you this piece of information about it.
What is its resistance value (or how many Ohms it is)?
For electricity to flow and light up a bulb, your Snap Circuit pieces must form this type of continuous, unbroken path.
What is a closed circuit?
Micro:bits have this built-in sensor to detect if you shake, tilt, or drop them, just like a smartphone does.
What is an accelerometer?
If your bracelet uses black and white beads, those two colors represent these two electrical states inside a computer's hardware.
What are "on" and "off"?
There are exactly this many Sustainable Development Goals designed to create a better future by the year 2030.
What is 17?
In Tinkercad's 3D workspace, you use this specific tool to combine multiple basic shapes into one solid object.
What is Group?
This component allows you to easily break or complete a circuit with your finger, turning your project on or off.
What is a switch?
The shiny gold strips at the bottom edge of a Micro:bit, where you can attach alligator clips for external sensors, are called these.
What are pins?
The standard code system that computers use to translate 8-bit binary numbers into human letters like 'A' or 'B' goes by this 5-letter acronym.
What is ASCII?
SDG 6 aims to ensure availability and sustainable management of sanitation and this vital natural resource for all.
What is clean water?
If you simulate a circuit in Tinkercad without a resistor connected to an LED, this cartoon symbol appears over the LED to show it took too much power.
What is an explosion (or starburst)?
In this type of circuit setup, components are arranged in a single path, meaning if one bulb goes out, they all go out.
What is a series circuit?
In a VEX robotics competition, this is the period where the robot must navigate the field using only pre-written code, without a human using a remote control.
What is the Autonomous period?
