ClassX Video Lessons Youtube Channel Code.org Helpful Hints: Lesson 11.3 Part 2 – If At Flower Then Get Nectar
Hey there! Today, we’re going to learn something fun about coding. Imagine you’re a bee flying around, and your job is to collect nectar from flowers. Let’s see how we can do this using some simple coding blocks!
First, we have some blocks that tell our bee how to move. We can use blocks like “move forward” and “turn right” to guide our bee to the first cloud. But wait, we need to check if there’s a flower under that cloud!
This is where the “if” block comes in handy. The “if” block helps us decide what to do next. It says, “if there’s a flower, do something.” So, what should we do if there’s a flower? That’s right, we should get nectar!
Here’s how it works: if our bee is at a flower, it will collect nectar. If there’s no flower, the bee won’t do anything. It’s like a little decision-maker for our bee!
After checking the first cloud, we need to move forward and check the next one. If there’s a flower under that cloud, our bee will get nectar again. It’s like a fun treasure hunt for flowers!
Now, here’s a little challenge for you. My code is a bit long, and I bet you can make it shorter. Try to find a way to use fewer blocks to do the same job. It’s like solving a puzzle!
Happy coding, and have fun collecting nectar!
Flower Hunt Game: Create a simple board game using a piece of paper and some markers. Draw a path with different spaces, some with flowers and some without. Use a small toy or a coin as your bee. Roll a dice to move your bee along the path. When you land on a space, decide if there’s a flower (you can mark these spaces with a flower symbol). If there is, say “If at flower, then get nectar!” and collect a token or point. This will help you practice using the “if” decision-making process.
Real-Life Observation: Go outside and observe real bees or other insects. Notice how they move from flower to flower. Discuss with a friend or family member how you think they decide which flower to visit next. Try to relate their actions to the “if” block concept. For example, “If the flower has nectar, then the bee will visit it.”
Code Your Own Bee Dance: Use simple dance moves to represent coding blocks. For example, a step forward can be “move forward,” a spin can be “turn right,” and a clap can be “if at flower, then get nectar.” Create a short dance routine that represents a bee collecting nectar from flowers. Perform it for your family or friends and explain how each move relates to coding blocks.
Here’s a sanitized version of the transcript:
“As you can see, I’ve already added the blocks in the workspace to move forward, turn right, and move forward to the first cloud. Now we need to figure out how to check if there’s a flower underneath the cloud, and if there is, we will get nectar. That’s what we’re going to use this ‘if’ block for. You can see that this says ‘if at flower, do whatever is inside.’
So, what do we need to put inside? That’s right, get nectar! If you’re at a flower, you’ll get nectar; if you’re not at a flower, the code inside this block won’t run. Next, we need to move forward and do it again. If there’s a flower underneath that cloud, get nectar.
As you can see, my code is a little bit too long, so I’ll leave it up to you to figure out how to make it shorter. Happy coding!”
