In this lesson, students join the Harvester on a farm to help pick ready crops using special blocks for navigation and collection. They learn to identify and harvest crops while also checking for sprouts, which require additional programming to determine their type before harvesting. This engaging activity emphasizes the importance of farming and the journey of food from the farm to our tables.
  1. What are the two types of blocks we use to help the Harvester on the farm?
  2. Why do we need to check for sprouts before picking crops?
  3. How does helping the Harvester teach us about where our food comes from?

The Harvester

Welcome to the farm! Today, we are going to help the Harvester, who is in charge of a big farm. She needs our help to pick the crops that are ready to be harvested. Are you ready to join in the fun?

How to Help the Harvester

To help the Harvester, we need to use some special blocks. These blocks help us move around the farm and pick the crops. There are two main types of blocks:

  • Move and Turn Blocks: These blocks help us navigate the farm. We can use them to move from one crop to another.
  • Pick Blocks: These blocks are used to collect the crops like corn, lettuce, and pumpkins.

In the bottom right corner of the screen, you will see how many crops are available at each spot. If there are more than one, we need to pick the crops multiple times in the same area.

Watch Out for Sprouts!

Sometimes, you might see sprouts. These are little plants that are just starting to grow. We won’t know what type of crop they are or how many there are until we run the program. So, our code needs to check what kind of crop is present before picking it.

Let’s Get Started!

The sun is shining, and it’s the perfect day to harvest. Let’s help the Harvester collect all the crops and have a great time on the farm!

Remember, farming is not only fun but also important. Farmers grow the food we eat every day. By helping the Harvester, we’re learning how food gets from the farm to our tables. Let’s enjoy this adventure and learn something new!

  • What do you think it would be like to be a farmer and take care of crops every day? Have you ever tried growing a plant or a small garden at home?
  • Why do you think it’s important to know what kind of crop is growing before picking it? Can you think of any other situations where it’s important to know what something is before you use it?
  • Imagine you are helping the Harvester on the farm. What would be your favorite crop to pick and why? Do you have a favorite fruit or vegetable that you like to eat?
  1. Farm Map Adventure: Create a simple map of a farm on a large piece of paper or a whiteboard. Use small objects like toy blocks or coins to represent different crops such as corn, lettuce, and pumpkins. Ask the children to use “Move and Turn Blocks” to navigate from one crop to another on the map. Encourage them to think about the shortest path and how many moves it takes to reach each crop. This will help them understand navigation and planning.

  2. Sprout Surprise: Plant a few seeds in small pots or cups and label them as “sprouts.” Ask the children to predict what type of plant each sprout will grow into. As the plants grow, have them observe and record changes over time. This activity will teach them about plant growth and the importance of observation and patience in farming.

  3. Harvest Count: Give each child a small basket and a set of toy fruits or vegetables. Hide different numbers of these items around the classroom or playground. Have the children use “Pick Blocks” to collect the items, counting how many they find in each location. Discuss with them why it’s important to know how many crops are available and how this helps farmers plan their harvests.

Here’s a sanitized version of the transcript:

This is the Harvester. She runs a large farm and needs your help to pick the crops that are ready to be harvested. Use the “move” and “turn” blocks to navigate the harvester from crop to crop. Then, use the pick blocks to collect all of the corn, lettuce, and pumpkins. The bottom right corner will show you how many are available at each spot. If you see more than one, you’ll need to pick the crops multiple times in the same area. Keep an eye out for sprouts! You won’t know what type of crop those are or how many there are until the program is run. So, your code may need to check what kind of crop is present before picking it. The sun is shining, and it’s time to harvest! Let’s get started.
