Exploring Materials – Learn about different materials – Compare their looks and feels – Is it rough or smooth? Hard or soft? – Discover how materials are used – Can you build with it? Is it for clothing? – Materials are everywhere | This slide introduces the concept of materials to first graders. It’s designed to spark curiosity about the everyday objects around them. Start by explaining that materials are what things are made from, like wood, plastic, metal, and fabric. Encourage the students to touch and feel different objects to compare textures and hardness. Discuss the uses of various materials, such as glass for windows or cotton for clothes. Highlight that materials have different properties that make them suitable for different purposes. Engage the students by asking them to name objects in the classroom and what material they are made from. This will help them connect the concept of materials to their daily lives.

Exploring Materials Around Us – What are materials? – Everything is made from materials like wood or glass. – Examples of common materials – Wood, plastic, metal, glass, and fabric are some materials we see daily. – Materials have different properties – Some materials are hard, others are soft. Some can bend, others cannot. – Why choose different materials? – We pick materials based on what we need, like glass for windows to see through. | This slide introduces the concept of materials to first-grade students. Materials are the substances from which objects are made. Start by showing examples of everyday items and discussing what materials they are made from. Explain that materials have different properties, such as hardness, flexibility, transparency, and strength, which determine their use in different objects. For instance, metal is strong and used for building structures, while fabric is soft and used for clothing. Encourage students to think about why certain materials are used for specific items and what properties make them suitable for that purpose. This will help them understand the importance of material selection in designing and making things.

Exploring Material Properties – Properties describe materials – Comparing hard and soft materials – Like rocks are hard and pillows are soft – Stretchy vs. stiff materials – Rubber bands stretch, wood is stiff – Discover uses based on properties | This slide introduces the concept of material properties to first graders, helping them understand that different materials have different characteristics and uses. Start by explaining that properties are special words that tell us what a material is like and what it can do. Give examples of hard and soft materials, such as rocks and pillows, and ask the children to touch and feel the difference if possible. Discuss stretchy materials like rubber bands and compare them to stiff materials like wood. Encourage the students to think about why certain properties are useful for specific purposes, like why stretchy materials are good for making bouncy balls. The goal is to help students start to observe and describe the world around them in terms of the properties of materials.

Let’s Compare Materials! – Comparing by looks and feels – Shiny or dull? Smooth or rough? – Is the material reflective like a mirror or not? Is it smooth like glass or bumpy like sandpaper? – Bendable materials – Can we fold it like paper or is it stiff like a rock? – Observing material properties | This slide is aimed at helping first graders understand the concept of comparing different materials based on their properties. Start by discussing how materials can look and feel different, such as some being shiny and others dull, or some being smooth while others are rough. Encourage the students to touch and see materials to notice these differences. Then, move on to the flexibility of materials, asking them to think about whether certain materials can be bent without breaking. Use everyday objects as examples to make it relatable. The goal is to make them observe and think about the properties of materials in their environment.

Activity: Material Hunt – Let’s explore materials in our classroom – Find items made of wood, plastic, metal, fabric – Discuss how these materials are alike – Are they all hard or soft? Can you bend them? – Discuss how these materials are different – Do they look the same? Feel the same? Are some heavier? | This activity is designed to engage first-grade students in a hands-on learning experience about the properties of materials. By searching for objects made of wood, plastic, metal, and fabric, students will learn to identify and compare the physical properties of these materials. Teachers should guide the students to observe the texture, flexibility, weight, and appearance of the items they find. Encourage students to think about why certain objects are made from specific materials. Possible variations of the activity could include grouping items by material, discussing the uses of each material, or even a scavenger hunt game to find as many items of a particular material as possible.

Group Discussion: Material Properties – Share your material findings – Discuss material properties – Is it hard or soft? Heavy or light? – Why materials are used for objects – Consider why a pillow isn’t made of wood – Think about material suitability – Why are windows made of glass? | This slide is meant to facilitate a group discussion among first-grade students about the properties of materials and their uses. Encourage the students to share the materials they found and describe their properties, such as texture, weight, and flexibility. Guide them to think about why certain objects are made from specific materials, like softness for comfort or transparency for visibility. The goal is to help students understand that the properties of materials make them suitable for different purposes. For example, a pillow is soft for comfort, and windows are made of glass to see through while keeping the elements out. This discussion will help students apply their observations to real-world objects and understand the practical applications of material properties.

Class Activity: Material Sorting Game – Sort objects by material – Create piles: wood, plastic, metal, fabric – Discuss why items go in each pile – Why is a spoon in the metal pile, but a cup in the plastic pile? – Think about material properties – Is it hard or soft? Heavy or light? Think about what the items are made of. | This activity is designed to help first graders understand the concept of categorization based on material properties. By sorting objects into piles of wood, plastic, metal, and fabric, students will begin to recognize the physical properties that define each material category. Encourage them to touch and feel the objects to determine their texture, weight, and rigidity. Ask guiding questions to stimulate thinking about why each object belongs in its respective pile, such as ‘What makes this block different from this spoon?’ or ‘Why would we use fabric for a shirt instead of metal?’ Provide a variety of objects for the students to sort and ensure that there are enough examples for each material type. This hands-on activity will enhance their understanding of materials and their properties in a tangible and interactive way.

Wrapping Up: Materials and Their Properties – Congrats on learning about materials! – Materials make our everyday items – Everything we use is made from different materials like plastic, metal, or wood. – Recall how we compared materials – Think about how we looked at color, shape, and size to see differences. – Sorting materials by their properties – We grouped materials based on hardness, flexibility, and more. | This slide is a conclusion to our lesson on the properties of materials. It’s meant to reinforce the concepts learned during the class and to celebrate the students’ understanding. Materials are the building blocks of everything we use, from our toys to our clothes. Today, we compared materials by looking at their color, shape, size, hardness, and flexibility. We also practiced sorting materials based on these properties. Encourage the students to continue observing the materials around them at home and to think about the properties that make each material unique and suitable for its use.

Homework Challenge: Exploring Materials – Take home your worksheet – Find objects for each material – Look for wood, plastic, metal, etc. – Draw or write about properties – Is it hard or soft? Heavy or light? – Share your findings in class | This homework assignment is designed to reinforce the concepts learned about materials and their properties. Students are to use their material worksheet as a guide to find objects around their home that represent different types of materials such as wood, plastic, metal, glass, and fabric. They should then observe and note the properties of these objects, like texture, weight, and flexibility. Encourage creativity in how they present their findings, either through drawings or written descriptions. This activity will help them apply their knowledge in a practical setting and prepare them to share and discuss their observations in the next class.
