Welcome to the World of Magnets!
– What is a magnet?
– Magnets pull certain objects
– Like paperclips, nails, and coins!
– Not all things are attracted
– Wood, plastic, and glass stay put
– Magnets have two poles
– North pole and South pole
|
Begin the class with a warm welcome to the fascinating topic of magnets. Ask the students if they know what a magnet is to gauge their prior knowledge. Explain that magnets have the ability to pull certain objects towards them, such as metal items like paperclips and nails, but not everything is attracted to a magnet; for example, wood, plastic, and glass will not stick to a magnet. Introduce the concept of magnetic poles, explaining that every magnet has a North pole and a South pole. Use simple language and real-life examples to make the concepts relatable for first graders. You can bring some magnets and a variety of materials to demonstrate attraction and repulsion.
What is a Magnet?
– Magnets pull certain things
– Like a magnet pulling paperclips
– ‘Magnetic force’ is this pull
– It’s like an invisible hand
– Not all things stick to magnets
– Only metals like iron are magnetic
– Fridge magnets stick because of iron
|
Introduce the concept of magnets to the students by explaining that a magnet is an object that can pull certain materials towards itself. This pulling force is known as ‘magnetic force.’ It’s important to note that magnets do not attract all objects, but are specifically attracted to certain metals like iron. Use simple examples like fridge magnets or a magnet pulling paperclips to illustrate these points. Encourage students to think of and discuss everyday objects that might contain iron and could be attracted to magnets.
Magnets: Attract or Repel?
– Magnets have ‘poles’: North and South
– Opposite poles attract each other
– Just like friends, North and South poles like to meet!
– Same poles repel each other
– North and North, like two stubborn mules, push away!
– Exploring attraction and repulsion
– Let’s see what happens when we try with different poles!

This slide introduces the basic concept of magnetic poles and their interactions to first graders. Begin by explaining that magnets are like special sticks with two ends, each called a pole. One end is the North pole and the other is the South pole. Use simple analogies, such as the idea of making new friends (attraction) or needing personal space (repulsion), to help students understand how opposite poles attract and like poles repel. Demonstrate with actual magnets to show attraction and repulsion. Encourage students to predict what will happen when different poles are put together. Plan a hands-on activity where students can experiment with magnets to see the effects of attraction and repulsion for themselves.
Let’s Explore Magnets!
– Activity: Find magnetic objects
– Use a magnet to test different classroom items
– Observe magnets attracting or repelling
– Bring two magnets close and see if they pull together or push apart
– Discuss why some objects stick
– Metals like iron stick to magnets, but plastic doesn’t
– Predict: Will it stick or not?

This slide introduces an interactive class activity to help first graders understand magnetism. Provide each student or group with a magnet and a set of objects. Guide them to use the magnet to test which objects are attracted and which are not, recording their findings. Then, demonstrate how two magnets can either attract or repel each other depending on their poles. Discuss with the class why certain materials like iron are magnetic, while others like wood or plastic are not. Encourage students to make predictions before testing each object to engage their critical thinking. The activity should be supervised to ensure safety and to facilitate learning through observation and discussion.
Magnetic or Not?: Exploring Magnetism
– Test objects for magnetism
– We’ll see which items are attracted to magnets
– Use common items like clips, coins, toys
– Paper clips are often metal, coins vary, and plastic toys are not magnetic
– Make predictions on magnetism
– Guess which items will stick to our magnet
– Observe and record results
|
This slide introduces a hands-on activity where students will explore the concept of magnetism by testing various objects. Provide a variety of objects for the students to test, including paper clips, coins, and plastic toys. Before the activity, ask the students to predict which objects they think will be magnetic. This will engage their critical thinking skills and allow them to apply their understanding of magnets. During the activity, encourage students to observe whether the objects are attracted to or repelled by the magnet and to record their findings. This will help them learn the properties of magnetic and non-magnetic materials in a practical setting.
Class Activity: Magnetic Hunt
– Let’s explore with magnets!
– Find magnetic objects around us
– Use a magnet to see what sticks to it
– Pair up for a magnetic adventure
– Two heads are better than one for this task
– Record your discoveries
– Use the worksheet to note down what you find
|
This activity is designed to be a fun and interactive way for students to learn about magnetism. Provide each pair of students with a magnet and a worksheet to record their findings. Encourage them to explore different areas of the classroom and test various objects to see if they are magnetic. Remind them to work together and share the magnet. As they explore, they should write down or draw the objects they discover to be magnetic. Possible objects they might find include paperclips, scissors, and other metal items. After the hunt, gather the class and discuss the findings. Ask students why they think some objects were magnetic and others were not, introducing the concept of magnetic materials such as iron, nickel, and cobalt.
Magnets: What We Learned Today
– Magnets can attract certain objects
– Some objects are attracted to magnets
– Examples: paper clips, nails, and coins
– Magnets can also push away, or repel
– Magnets have a magical force!
– Like the way opposite poles attract, same poles repel
|
This slide wraps up our lesson on magnets by summarizing the key points. We learned that magnets have a special force that can either attract or repel certain objects. Encourage the students to think about and name objects they learned that are attracted to magnets, such as paper clips, nails, and some coins. Highlight the concept of attraction and repulsion, explaining that just like friends can be drawn to each other, magnets can too, but they can also push away if they are the same kind (like two north poles or two south poles). Use simple language to ensure understanding and ask the students to share their thoughts on how magnets work in their own words.
Magnetic Hunt Review
– Share your magnetic findings
– Discuss magnetic vs non-magnetic
– Why did magnets stick to some things?
– Understanding magnetism
– Magnets attract iron, nickel, cobalt
– Celebrate our young scientists!

This slide is for reviewing the magnetic hunt activity. Start by having each student share the objects they found that were attracted to the magnets. Facilitate a discussion on why some objects were magnetic (made of iron, nickel, or cobalt) and others were not, helping them understand that not all materials are attracted to magnets. Praise their efforts and curiosity throughout the activity, reinforcing their identity as ‘scientists’ and encouraging a love for learning and exploration. For the activity, consider having different stations with a variety of materials for students to test with magnets, or a scavenger hunt where they search for items that will be attracted to magnets.
