Ecosystems, food webs and energy flow SCIENCE · 5TH GRADE Name Date TAKE-HOME PRACTICE Science · 5th Grade 25 minutes WHAT THIS BUILDS Traces energy from the sun through a food web and predicts the effect of removing one species. 1 THE TWO-MINUTE CHECK ASK "If all the foxes disappeared, what happens to the rabbits, and then to the grass?" A SOLID ANSWER A two-step chain of consequences, not just the first one. Not yet Getting there Solid 2 WEB OF STRING You need: String or wool, Cards with local species names Write local plants and animals on cards and lay them out. Connect each with string wherever one eats the other. It becomes a web, not a chain. Cut one string — remove a species — and trace which connections fail. Ask what happens to the numbers of everything else, two steps out. Find a real example: wolves in Yellowstone, or a local invasive species. SAY THIS WHEN IT STALLS "That's what happens next. And then what? Keep going two more steps." A five-species chain rather than a full web. Add decomposers and nutrient cycling, and explain why the web needs them.

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!

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?

Coding — Variables — Part 1 SCIENCE · 1ST GRADE Name Date Fill in this page as you do your investigation. What are we finding out? What are variables and how do they store data? What we need: computer, code editor, practice exercises What I think will happen: Write your own: If I change ___, then ___ because ___ What I will change: Variable name and value assigned What I will watch: What the program outputs using the variable What to do: 1. Learn what a variable is 2. Create a variable and assign a value 3. Use the variable in your program 4. Change the value and observe 5. Try different data types What we saw: Variable Name Value Data Type score name Trial 3 What I learned: Variables are useful because... www.littleactivity.com 1st Grade · Science
