Series & Parallel Circuits SCIENCE · 8TH GRADE Name Date Read the passage, then answer the questions below. In a series circuit the components sit one after another on a single loop, so the same current flows through every one and breaking the circuit anywhere stops everything. In a parallel circuit each component sits on its own branch, so each has the full supply voltage and one can fail without stopping the others. That is why household lighting is wired in parallel — a blown bulb leaves the rest working. Adding more bulbs in series dims them all, while adding more in parallel does not. Questions: 1 What happens if a series circuit is broken at one point? 2 Why is household lighting wired in parallel? 3 What happens when you add bulbs in series? www.littleactivity.com 8th Grade · Science

Coding — If & Then — Part 1 SCIENCE · 1ST GRADE Name Date Learn the concept, study the code, then try the challenge! Coding Concepts Coding means writing instructions that a computer can follow step by step. Code Example: // Every program has: // 1. Input — data going in // 2. Process — what to do with it // 3. Output — the result Steps: 2. Plan your solution (algorithm) 5. Debug and improve 3. Write the code 1. Understand the problem 4. Test your code Try It! Write step-by-step instructions to make a peanut butter sandwich. Be specific! Debug Challenge: Your instructions say 'put peanut butter on bread' but the robot puts the jar on the bread! R… My Fix: www.littleactivity.com 1st Grade · Science
Coding — Events — Part 1 SCIENCE · 1ST GRADE Name Date Learn the concept, study the code, then try the challenge! Events & Control Events start your code. Control blocks like loops and if/then make decisions. Code Example: when [space v] key pressed if <touching [edge v]?> then turn (180) degrees end repeat (10) move (10) steps end Steps: 5. Test different event triggers 4. Try 'when key pressed' events 3. Use 'if...then' to check conditions 1. Start with a 'when green flag clicked' event 2. Add a 'forever' loop to keep code running Try It! Make a sprite bounce off the edges using events and if/then blocks. Debug Challenge: My sprite only moves once instead of forever. What's wrong?
