Lesson Bridge:

Connect this lesson to Seeds (1) by asking students if they remember what a seed needs in order to have enough energy to grow big and strong. Demonstrate that the nutrients provided for the seed allow it to form six different plant parts that enable us to eventually enjoy it as food!

Lesson Overview:  

In this lesson, students will gain an understanding of the six plant parts and their individual functions. The class will then identify, harvest, and eat the six plant parts as garden tacos!

Learning Objectives by Grade:

• K:

• K-LS1-1 How do different parts of plants help them survive?
• K-ESS2-2 How do people and plants change their environment to meet their needs?

• 1:

• 1-LS1-1 How do different parts of plants help them survive?
• 1-LS3-1 How are young plants like--but not exactly like--their parents?

• 2:

• 2-LS4-1 How do different plants survive in different habitats?

Essential Question(s) that Connect CCCs and SEPs:

• What are the 6 plant parts that give the plants their structure?(Structure and function: Obtaining, evaluating, and communicating information)
• What are the functions of each plant part? (Structure and function: Obtaining, evaluating, and communicating information)

Vocabulary

Plant Parts- The different parts of a plant are roots, stems, leaves, etc. Just like our bodies have parts (legs, arms, hands) so does a plant.

Plant Life Cycle- The steps all plants go through in their life, beginning with a seed that grows.

Roots- The part of the plant that grows underground holds the plant upright and absorbs water and food from the soil.

Stem- The main part of the plant that grows straight up and supports the branches, leaves, and flowers that grow from it.

Leaves- The flat, green part of the plant that grows off of the stem. Its main function is to make food for the plant.

Flower- The part of the plant that blooms and attracts pollinators.

Fruit- When a plant makes a flower, that flower turns into a fruit that contains the seeds inside of itself.

Seeds- The part of a plant that can grow into a new plant.

Materials:

• Anything you can find in the garden that represents one of the 6 plant parts! Lettuce (leaves), celery  (stems), tomatoes, cucumbers (fruit) Sunflower seeds and/or cooked rice or quinoa(seeds), calendula or other edible flowers (flowers), carrots, radishes, or beets (roots).
• Compostable gloves + hand sanitizer
• Other garden fresh goodies (mint and other herbs, edible flowers, anything tasty to add to the tacos).
• Cooking Kits
• Optional Worksheet Parts of a plant Worksheet
• Sauce or guacamole (optional)
• Pre-cooked rice (optional)
• Series #2 Garden Journal (optional)

Prep:

• If you don’t have tables in your garden, check them out from the custodian at your school site to set up in the garden, or plan to do a portion of the lesson in the classroom.
• Buy any vegetables needed that you don’t have in abundance in the garden. Consider asking your food services staff, they may have extra!
• Sanitize all the table surfaces and the cooking gear.
• Take a walk through the school garden to know what is available for harvesting from each of the plant part groups!
• Set up a cooking station for part three of the lesson. Wash cooking surfaces well with soap and warm water, rinse, and dry.

Activity Procedure:

Engage:

Begin with a classroom discussion in the seating area in your garden or classroom. Write the following questions on the board, record answers, and discuss with the class:

What are some of your favorite fruits and vegetables that you eat (Think, Pair, Share)? What are some other foods you like to eat? As you call on students, write down or draw the things they say. Did you know that common components of our diets include roots, stems, leaves, flowers, fruits, and seeds? Take a look at the board. Does anyone see a fruit? How about a leaf or root? What about a flower? (broccoli, artichokes, and cauliflower). A fruit? (Tomato, bell pepper, etc). These are the 6 plant parts, and we can eat things from every category.  

Explore:

Go to the garden and have students observe the different plant parts they can find there. Harvest anything edible you might want to add to the tacos. To make this organized you can have separate bowls for the different plants that are in season at different times.  

Sentence Frame: When we eat celery, we are eating a plant’s _________.

Explain:

Think, Pair, Share: What do each of the parts of the plants do?

Flowers: attract pollinators which help the plant make seeds. Seeds: These are like the babies the plant has. Stems: Help hold the plant up above the ground so it doesn’t rot and get it closer to the sun so it can get energy. Leaves: Help the plant get energy from the sun. Roots: Help the plant get water and nutrients from the soil, and help it stand up tall. Fruits: Attract animals so they can help move the seeds inside the fruit to a new place.

Thumbs up/down: Who wants to make some tacos to help us go over the six plant parts?

Action: Taco Making!

*You can either divide and conquer or lead the cooking demonstration and have students contribute with their words and ideas.

1. Review your Garden Agreements
2. Divide students into groups to work on different parts of the plant taco.

Group 1: rinse lettuce- your taco shell!

Group 2: cut up the fruits.

Group 3: cut up celery

Group 4: grate the carrot or other root vegetable.

Group 5: Separate petals from flowers and/or tear up fresh herbs.

3. Once all the ingredients are ready, put them into separate bowls. Have students form a single file line and one at a time have them come up to choose what they want in their tacos (it is important that you do the serving to ensure that it can be done in a hygienic way!)
4. Incorporate some mindful eating concepts. Before students take a bite, ask them what their taco smells like, looks like, and feels like! Remind students not to ‘Yuck my Yum’
5. Remind students not to ‘Yuck my Yum’  When students are done eating their tacos, have them help with cleanup.

Reflect:

What was your favorite part of the taco(Think, Pair, Share)? Who can name all 6 parts of a plant(Think, Pair, Share)? What do the different parts do?

Extension Activities:

• Write or tell a story about your 6 plant part taco. What did you use for each plant part?  Use your 5 senses to describe your taco.
