LESSON OVERVIEW

Content: Understanding how rigid and soft objects change/move in shape

Question/Problem: How do the rigid and soft objects change or move in shape when we use them in different activities?

BIG IDEA

4. Changing the movement of an object requires a net force to be acting on it.

CONTENT STANDARD

Science processes help in observing and predicting how things move

LEARNING COMPETENCY

1. Participate in guided activities to discover and predict how rigid and soft objects can be moved and/or changed in shape.

Laude, M. - REVISED

DISCUSSION OF THE CONCEPT

Let's explore the properties of rigid and soft objects and how these can be moved and changed in shape using the link attached.

Next Generation Science Standard (NGSS) Alignment

K-PS2-1. Plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.

Science and Engineering

Practices

Planning and carrying out investigations

Planning and carrying out investigations to answer questions or test solutions to problems in K-2 builds on prior experiences and progresses to simple investigations, based on fair tests, which provide data to support explanations or design solutions.

With guidance, plan and conduct an investigation in collaboration with peers. (K-PS2-1)

………………………………………..

Connections to Nature of Science

Scientific Investigations Use a Variety of Methods

Scientists use different ways to study the world. (K-PS2-1)

Disciplinary Core Idea

PS2.A: Forces and Motion

Pushes and pulls can have different strengths and directions. (K-PS2-1),(K-PS2-2)
Pushing or pulling on an object can change the speed or direction of its motion and can start or stop it. (K-PS2-1),(K-PS2-2)

PS2.B: Types of Interactions

When objects touch or collide, they push on one another and can change motion. (K-PS2-1)

PS3.C: Relationship Between Energy and Forces.

A bigger push or pull makes things speed up or slow down more quickly. (secondary to K-PS2-1)

Crosscutting Concept

Cause and Effect

Simple tests can be designed to gather evidence to support or refute student ideas about causes. (K-PS2-1),(K-PS2-2)

Math Connections

Mathematics helps students to analyze, compare, and measure how objects, whether rigid or soft, change/move in their shapes when force is applied.

Compare the amount of force acquired to rigid and soft objects.
Measuring the estimated length of changes before and after moving or changing an object's shape.

TLE Connections

In the TLE connection, practical application is important as it helps students understand the concept effectively, by identifying the appropriate materials for various crafts and projects. Aligned with the EPP/TLE Curriculum Guide, helps students to practice proper handling of materials and tools, ensuring its safety in various activities.

Identify the tools to be used based on their physical properties.

Choosing suitable materials for rigid and soft object activities depending on their purpose.

Government Thrust

Promotes SDG 4: Quality Education that fosters inquiry-based learning and hands-on activities where students explore the physical properties of objects and how it reacts to movements. It also aligns with SDG 12: Responsible Conduction and Production focusing on identifying and recycling materials.

TPACK INTEGRATION

In this lesson, the teacher will be able to integrate various technology tools to enhance and support students and teaching learning process - such as Simulator for introducing the concept, PowerPoint Presentation for engagement and creative discussion, a Youtube video for expanding the information, printed worksheets, and other components of media. This utilizes engaging, effective, and interactive discussion that includes collaborative learning, inquiry-based learning, problem-solving learning, and STS approach learning.

GRP INTEGRATION

In this lesson, all students regardless of their gender are given equal opportunities to share their ideas and insights with the class. The learning process promotes fair treatment by applying equal participation and turn-taking. Activities are designed to ensure balanced roles among students, avoiding assigning tasks based on gender norms. Lastly, every student is engaged in a more inclusive and gender-responsive learning environment, where their opinions are recognized and valued, ensuring that all students feel heard and respected when sharing their observations about the rigid and soft objects and how they change/move in shape.

7E's Detailed Lesson Plan

Objectives

At the end of this lesson, the students should be able to:

A. Describe the difference between rigid and soft objects based on their physical properties;

B. Explain the importance of selecting appropriate and suitable materials for different activities; and

C. Create eco-friendly items using recycled materials suited to the properties of rigid or soft objects.

ELICIT

In this phase, the teacher activates the students' prior knowledge about rigid and soft objects by connecting the lesson to their prior experiences. The teacher will start to ask questions:

Have you ever tried to hold rigid and soft objects? If yes, give some examples.
What do you know about soft and rigid objects?
Can you give some objects that are easily bent?
How about those objects that do not bend easily?

After that, students will be answering a KWL Chart and thinki about (W) what you already know and (W) what you want to know about how rigid and soft objects move or change in shape.

KWL Worksheet

ENGAGE

The teacher stimulates the curiosity of the students by introducing the concept through an engaging activity called "Guess Me". The teacher will show a mystery box filled with different items that correspond to the physical properties of rigid and soft objects. The teacher will ask a student to pick one item inside the box and complete the following tasks:

Feel the item and describe its characteristics.
Identify which property the item belongs to.

Followed by asking questions:

What makes an object rigid or soft?
What do you think are the different ways to make an object move?
How does a movement make an object change in shape?

EXPLORE

Next, the students will be divided into two groups. Each group will explore their surroundings within the classroom to observe and identify objects that are either rigid or soft. The students will record their findings using a table that classifies the properties of different objects and will test each object by applying forces and movements.

First, the students will need to (1) identify the item and its property, (2) describe the items by identifying its size and shape using the worksheet.

Followed by a question:

Which objects were the easiest to change or move its shape?
How did each object respond to applied movements? Explain.
What do you think causes an object to change or resist movement in shape?

Explore Worksheet

EXPLAIN

To further explain the topic, both the teacher and students will actively participate in a discussion to deepen the understanding of the concept.

First, the students will present their findings from the exploration phase by sharing the information they have gathered and observed. Starting by answering the guide questions:

How did you classify the objects, and why?
What kind of movements did you apply to each object?

Next, the teacher will facilitate the discussion by playing a short video clip and presenting a powerpoint presentation to explain the topic in a detailed flow that inputs the ideas of the concept. The discussion of the information will focus on explaining the concept of rigid and soft objects, the different ways of movements and how these objects respond to different movements applied.

Rigid and Soft Objects

PowerPoint Presentation

ELABORATE

In this phase, students apply and deepen their understanding by working in groups to create eco-friendly materials using recycled objects that match assigned physical properties (soft or rigid). Guided by a key question, they will:

Choose and justify materials,
Sketch and label their design,
Measure materials,
Explain how the properties affect shape or movement, and
Discuss the creativity, safety, and functionality of their product.

After presenting, students reflect on the importance of choosing safe and appropriate materials for creating or building innovations.
