Creating a Ping Pong Game in mBlock

  Creating a Ping Pong Game in mBlock is a fun and interactive way for students to learn programming concepts like loops, conditionals, and events. Here's a step-by-step guide: Objective Students will create a basic ping-pong game where: 1.     A ball moves across the screen. 2.     Players control a paddle to bounce the ball. 3.     The game ends if the ball misses the paddle. Step-by-Step Instructions 1. Setup the Stage Open mBlock and switch to the Sprite Tab . Choose or draw a simple backdrop (e.g., a solid background or a sports theme). 2. Add Sprites Ball : Click "Choose a Sprite" and select or draw a ball. Paddle : Add a new sprite, like a rectangle, to represent the paddle. 3. Code for the Ball 1.     Initialize the Ball : o    Add the following script to the Ball: plaintext Copy code When Green Flag clicke...

Positional and Non-Positional Number Systems,

  In computer science and mathematics, number systems are fundamental for representing numerical values. They are broadly categorized into Positional and Non-Positional Number Systems , each with unique characteristics and applications. 1. Positional Number System In this system, the position of each digit relative to others determines its value. The value of a number is computed based on a base or radix, and each position represents a power of the base. Key Characteristics: Base/ Radix : The number of distinct digits used, including 0. For example: Binary (Base 2): Uses digits 0 and 1. Decimal (Base 10): Uses digits 0 through 9. Hexadecimal (Base 16): Uses digits 0-9 and letters A-F. Positional Weight : Each digit’s value is multiplied by the base raised to the power of its position. For instance, in decimal 432=4×102+3×101+2×100432 = 4 \times 10^2 + 3 \times 10^1 + 2 \times 10^0432=4×102+3×101+2×100. Examples in Computin...

STEM - Coding - Computing

Image
STEM stands for Science, Technology, Engineering, and Mathematics. In simple terms: Science : Exploring the world around us, like studying plants, animals, and space. Technology : Using tools and gadgets, like computers and tablets. Engineering : Building and designing things, like bridges and robots. Mathematics : Working with numbers and shapes to solve problems. Coding is like giving instructions to a computer to make it do things, like playing a game or creating an app. Computing means using computers to solve problems and complete tasks, like typing a document or searching the internet. Together, STEM-coding-computing for kids means learning how to explore, build, and solve problems using science, technology, and computers in a fun and creative way. MCQs Sure! Here are 50 multiple-choice questions (MCQs) for kids based on the STEM-coding-computing concepts: 1. **What does the "S" in STEM stand for?**    - A) Space    - B) Science    - C)...
