Lesson Q1 L1 – The Petal Pail Garden Adventure

Lesson Overview

Quarter 1 · Unit 1: Our Petal Pail Garden Begins · Week 1 · Grades 1–2 · Lesson length: 40 minutes

Essential Question: What do plants need to grow?

Lesson Focus: A mystery tub covered in question marks is full of clues about how plants grow.

Why It Matters: This launch builds wonder and gives students their first scientific habit: observe before you explain. Sorting the tub items into Water, Sunlight, Soil, and Care becomes the class Garden Needs chart that every later lesson refers back to.

Teacher Note: The Talking Tub is inspired by Claire Warden’s approach (cited in the original lesson). Keep the tub closed until Explore so curiosity builds.

Standards & Learning Targets

Standards Alignment

NGSS Performance Expectations (builds toward): 2-LS2-1 — Plan and conduct an investigation to determine if plants need sunlight and water to grow.

ISTE Standards for Students: 1.3 Knowledge Constructor (1.3d: build knowledge by actively exploring real-world issues and problems)

Student Learning Targets

Learning Targets — students will be able to

• Name the gardening items in the tub and tell how each one helps a plant.

• Sort items to show four things a plant needs: water, sunlight, soil, and care.

• Draw and label a prediction of what their Petal Pail will look like.

Key Vocabulary: observe · predict · soil · seed · sunlight · care

Materials & Teacher Prep

Materials Needed

• Talking Tub (cardboard box covered with question marks)
• Small pail with drainage holes, small bag of potting soil, seed packets (marigold and garden cress)
• Watering bottle with a pinhole cap, garden gloves, plastic magnifying glass, paper cutout of the Sun
• Four table-tent cards: Water, Sunlight, Soil, Care
• Chart paper; crayons; Student Workbook page 1.1

Teacher Prep Checklist

• Decorate the tub and load the items listed.
• Make the four table-tent cards and place them where everyone can see.
• Start the class Garden Needs chart (four boxes) and a Question Wall.
• Pre-assign shoulder partners (A and B) for Timed Pair Share.

Safety: Seeds, beans and other small items are choking hazards for young children: hand them out in counted sets, keep them away from mouths and noses, and collect them at the end. Children wear gloves or use scoops for soil and compost, keep hands away from faces, and wash hands with soap for 20 seconds afterward. Moisten dry soil before digging to keep dust down.

Lesson Flow & Timing

Phase 1 · Engage — The Hook

Teacher Talk

PCM: Curiosity. “Today we have a mystery tub filled with objects that hold clues about how plants grow. Like real scientists, we will use our eyes, hands, and curiosity to investigate each item. What do you think we might discover inside?” Teach the words seed and care: you say them, children echo, and everyone points to an example.

Ask Students: “What do you think is inside?” “What clues might help a plant grow?”

PCM Differentiation

Thinker Students: “If you could only pick one item to help a seed grow, which would you pick? What is your reason?”

Harmonizer Students: “Who in your family takes care of plants or pets? What do they do to help them grow?”

Phase 2 · Explore — Kagan Cooperative Activity

Cooperative Structure

Kagan structure: RallyRobin. Partners take quick turns naming what each item might be used for, so every child talks during the reveal. (See the Teaching Reference for the structure’s steps.) Hold up or point to an example as children say soil with you.

Step-by-Step

• Step 1 — Reveal (4 min): Remove items one at a time: pail, soil, seed packets, watering bottle, gloves, magnifying glass, paper Sun. Hold each up and pause: “Look closely. What do you think this is?”

• Step 2 — RallyRobin (5 min): After each item, partners RallyRobin ideas for two turns each: “What do we use this for when we garden?” Record a few ideas on the board.

• Step 3 — Draw and label (6 min): Students draw three items on Workbook 1.1 or in their journals and copy a label (seed, Sun, soil).

Teacher Moves During Explore

• Model the sentence frame: “I think this is for ___ because ___.”

• Accept every idea; record exact student words on the Question Wall.

• Notice who names water, light, and soil on their own — this is baseline data.

Phase 3 · Explain — Direct Instruction

Mini-lesson — Garden Needs Sort. Ask students what each revealed item is for and why a plant might need it; use their words first, then add the science words as you sort the items together.

• Sort: Hold up each item and ask, “Where should we put this?” Students place it by Water, Sunlight, Soil, or Care.

• Why: For each item ask, “Why do you think plants need this?” Connect: a watering bottle gives thirsty plants a drink; soil is a cozy home; the Sun helps plants grow.

• Think: “Could a plant grow with water but no sunlight? Why or why not?” Accept predictions — the class will test this idea later.

Key Message: Plants need water, sunlight, soil, and care. Scientists look closely before they explain.

Check for Understanding — Ask Students: “Which card does the watering bottle go with?” “What would happen if we forgot to care for our plants?”

Phase 4 · Elaborate — Student Product & Differentiation

Student Product

Each student draws their future Petal Pail and shows one thing they will do to help it grow. (Student Workbook page 1.1.)

Differentiation by Grade

Grade 1: Draw the pail and circle one need on the workbook page; dictate a label to an adult if needed.

Grade 2: Draw the pail and complete the frame “I will help my seeds grow by ___.”

ELL Support: Point to the real object while saying the word; post picture cards for water, sun, soil, and care.

Phase 5 · Evaluate — Closure, Exit Ticket & Assessment

Exit Ticket

Ask each child (oral, show-me, or drawn — no reading required):

1. Point to one item that gives a plant a drink.

1. Tell your partner one thing a plant needs.

1. Draw one thing you will do to care for your Petal Pail.

Answer Key / Look-Fors: (1) Watering bottle. (2) Water, sunlight, soil, air, or care. (3) Watering, keeping in light, checking soil, being gentle.

Expanding Circles — how does this connect to… Self — What do you need to grow? • Classroom — How will our class share plant jobs? • School — Where could plants grow at our school? • Community — Who grows plants in our neighborhood? • World — Why do people everywhere grow plants?

Formative Assessment

• Meets (3): Names at least three plant needs and matches tub items to them.

• Approaching (2): Names one or two needs; matching needs prompting.

• Not Yet (1): Cannot yet name a plant need — revisit the Garden Needs chart with the real items before Lesson 1.2.

Extend & Looking Ahead

• Extension: Optional: the original activity sheet asks students to match pictures to Water, Sunlight, Soil, and Care (Workbook 1.1).

• Harvesting Wisdom connection: Harvesting Wisdom podcast with UFE founder, Episode 1: Urban Farming Education (pairing from the 2024 Petal Pails lesson plans; preview it and choose a short clip that fits this lesson).

• Looking Ahead: Lesson 1.2 looks closely at soil, the plant’s home.
