Welcome to the World of Heat! – Greeting and introduction to heat – Understanding what heat is – Heat is energy that makes things warm. – Observing heat from the sun – The sun gives off heat we can feel. – Discussing how the sun feels – When standing in sunlight, we feel warm. | Begin the class with a warm greeting and introduce the topic of heat, which is a form of energy. Explain to the students that heat is what makes things warm and can come from various sources, like the sun. Ask the children to share their experiences of feeling warm when standing in the sunlight, and use this to explain that the sun is a natural source of heat. Encourage them to think about and discuss the sensation of warmth, helping them connect the concept of heat to their personal experiences. This will set the foundation for further discussions on how heat affects the environment and objects around us.

Exploring Heat Energy – Heat is energy that warms – Heat sources: sun, lamps, bodies – The sun warms the Earth, lamps light up rooms, our bodies stay warm – Heat uses: cooking, staying warm – We cook to make food safe and tasty, wear coats to stay warm in winter – Some toys use heat to work – Like a toy car that moves after being in the sun | This slide introduces the concept of heat as a form of energy to first graders. It’s important to use simple language and relatable examples to help them understand how heat affects everyday life. Explain that heat comes from different sources, including the sun, which is essential for life on Earth. Discuss how we use heat in our daily activities, such as cooking food to make it edible and keeping ourselves warm. Highlight that some toys, like solar-powered cars, use heat from the sun to function. Encourage students to think of other examples where they have experienced heat and how it made them feel or affected objects around them.

How Does Heat Move? – Heat moves when objects touch – Like when you hold hands with a friend – Heat can travel through the air – Like wind blowing warm air around – Heat can come from light – Like sunshine warming your face – Making s’mores shows heat movement | This slide introduces the concept of heat transfer to first graders in a relatable way. Explain that heat can move in different ways. Conduction is when heat moves between things that are touching, like when you hold hands with someone and feel their warmth. Convection is when heat travels through the air, similar to feeling the warm breeze. Radiation is heat coming from a light source, like feeling the sun on your skin. Use the example of making s’mores to illustrate these concepts: the heat from the fire (radiation) cooks the marshmallow, which then melts the chocolate when they touch (conduction), and the warm air can make the surrounding area feel warmer (convection). Encourage students to think of other examples where they experience heat moving in these ways.

Predicting Heat Flow – Heat travels warm to cool – Like a car going downhill, heat moves from hot areas to cold ones. – Hot things can warm our hands – When we touch something hot, heat jumps to our hand like a frog to a lily pad! – Guess heat’s path with ice in water – What happens to the ice cube in warm water? Will the ice warm up or the water cool down? | This slide introduces the basic concept of heat transfer to first graders. It’s important to use simple and relatable analogies to explain how heat moves from warmer objects to cooler ones. Encourage the students to think about their experiences, like touching a warm cookie or holding a cold ice pop. For the activity, ask them to predict what will happen when an ice cube is placed in warm water and discuss the idea of heat moving to the ice from the water, causing the ice to melt. This will help them understand that heat flows to cooler areas and can change the state of objects.

Understanding Heat Flow: Examples – Ice cube melting in hand – Heat transfers from your warm hand to the cold ice, causing it to melt. – Warmth from hot cocoa – The heat from the cocoa makes your hands feel warm. – Steam rising from soup – Heat turns soup water into steam, which rises. – Heat moves to cooler areas | This slide aims to help first graders understand the concept of heat flow through relatable examples. Heat flow is the movement of heat from a warmer object to a cooler one. When an ice cube melts in a child’s hand, it’s because the heat from their hand is moving to the ice. Similarly, when they feel warmth from a cup of hot cocoa, it’s the heat transferring to their hands. Steam rising from a bowl of soup is another example of heat causing water to evaporate and move to the air. These examples will help students grasp the idea that heat flows from warmer to cooler objects, which is a fundamental concept in understanding temperature changes.

Class Activity: Feeling the Heat! – Experiment with water temperatures – Feel the warm and cold cups – Draw heat movement – Imagine how heat travels from warm to cold – Discuss our findings – Share your drawings and ideas with the class | This activity is designed to give students a hands-on experience with temperature and heat flow. Provide two cups for each student, one with warm water and one with cold water. Guide them to carefully feel the outside of each cup without peeking, and guess which one is warm. After the guess, they can look to see if they were right. Then, ask the students to draw their interpretation of heat moving from the warm cup to their hands or from their hands to the cold cup. This will help them visualize the concept of heat transfer. After the drawing, facilitate a discussion where students can share their drawings and describe what they think is happening with the heat. This will reinforce their understanding of heat flow. Prepare additional activities such as comparing room temperature objects to the warm and cold cups or using different materials to feel the heat transfer.

Understanding Heat Flow – Heat moves from warm to cool – We can feel and see heat – Like feeling the sun or a warm stove – Find warmth when you’re cold – Like a blanket or warm clothes – Heat is important in our lives | This slide concludes our lesson on heat flow. It’s important for students to grasp that heat is a form of energy that naturally moves from a warmer place to a cooler one. Give examples of heat they can feel, such as sunlight or the warmth from a stove. Also, discuss how we can see heat’s effects, like steam from a hot cup of soup. Remind them of practical applications, like using a blanket or putting on warm clothes when it’s cold. This reinforces the concept of heat transfer in a way that’s relatable to their daily lives. Encourage them to think of more examples where they experience heat.

Review and Goodbye: Heat Adventures – Recap: What is heat? – Discuss: How does heat move? – Heat can move in three ways: conduction, convection, radiation. – Celebrate our learning – Looking forward to next time | This slide is meant to wrap up the day’s lesson on heat. Start by asking the students what they learned about heat to refresh their memory. Encourage them to share one way that heat can move, reinforcing the concepts of conduction, convection, and radiation. Praise their efforts and participation throughout the lesson to boost their confidence. Let them know you’re excited to see them in the next class and encourage them to observe heat in action at home or in their environment.
