Lesson Plan for Toddler - Nature Study - Objects That Float In Water Ii

### Lesson Plan: Objects that Float in Water II #### Age Group: Toddlers (Ages 2-4) #### Duration: 30-40 minutes --- #### **Objective:** - Toddlers will explore and understand the concept of buoyancy by identifying objects that float and sink in water through a hands-on activity. #### **Materials:** - Large, clear plastic tub or small kiddie pool filled with water - Variety of objects (e.g., rubber duck, sponge, cork, plastic spoon, stone, metal spoon, coin, leaf, piece of wood, plastic bottle cap, small toy boat) - Towels or sponges for clean-up - Aprons or old t-shirts to protect clothing - Visual aid chart with "Float" and "Sink" columns - Stickers or markers for charting results --- #### **Preparation:** 1. **Setting Up:** - Fill the large plastic tub or kiddie pool with water. - Gather a diverse selection of objects. - Prepare the visual aid chart with columns labeled "Float" and "Sink". - Arrange aprons for the children to wear. 2. **Safety Measures:** - Ensure the water tub is on a stable surface. - Always supervise the children closely during water activities. - Have a first aid kit on hand. --- #### **Introduction: (5-10 minutes)** 1. **Greeting:** - Gather the children in a circle and greet them warmly. - Begin by reviewing the previous lesson where they explored objects that float and sink. 2. **Discussion:** - Ask the children if they remember any objects that floated or sank from the last lesson. - Explain that today, they will continue to investigate what kinds of objects float and which ones sink. --- #### **Activity: Experiment (15-20 minutes)** 1. **Hands-On Exploration:** - Show the children the tub of water and the variety of objects. - Explain the activity: One at a time, each child will choose an object, predict if it will float or sink, and then place it in the water to see what happens. 2. **Conducting the Experiment:** - Call on a child to choose an object and discuss or guess their prediction. - Help them carefully place the object in the water. - Observe the object together and note whether it floats or sinks. - Place a sticker or marker on the visual aid chart under the appropriate column (Float or Sink). - Repeat the process with each child and object. 3. **Discussion and Questions:** - As each child interacts with the objects, ask open-ended questions like: - "What do you see happening?" - "Why do you think this object floats?" - "Why do you think this object sinks?" --- #### **Conclusion: (5 minutes)** 1. **Review Results:** - Gather the children around the completed visual aid chart. - Review which objects floated and which ones sank. - Discuss any patterns or common characteristics noticed (e.g., lightweight objects tend to float, heavy objects tend to sink). 2. **Wrap-Up:** - Praise the children for their participation and curiosity. - Sing a relevant song or rhyme about floating and sinking. - Encourage children to try finding floating and sinking objects at home with their parents. --- #### **Clean-Up: (5 minutes)** - Guide the children in helping to clean up the activity area. - Ensure all water is properly discarded and the area is dry to prevent slips. #### **Follow-Up Activities:** - Provide coloring sheets of floating and sinking objects. - Engage in water play with floating and sinking toys during free playtime. - Read a related storybook about water and objects that float/sink. --- ### **Note to Educators:** This lesson plan is designed to be interactive and engaging for toddlers while ensuring it incorporates an educational exploration of basic physics concepts in a playful and accessible way. Always be mindful of each child's response and comfort with water activities. Adjust the pace and approach as needed to match the developmental stages and interests of the children.
