Those stainless steel are thin and have a ferromagnetic underneath. However, the newly designed ones are supportive. Stainless steel dishwashers also cannot hold magnets.

They tend to ruin the surface by scratching. Some stainless steel with fingerprint resistance features is not safe from magnets. Nickel is mixed with stainless steel to get a sturdy structure that prevents magnets from sticking. Most stainless steel fridges do not feature a magnetism character. Do not put magnets on them as they may damage the finish of the surface. Some stainless steel is fingerprint-resistant. Most new stainless steel appliances after the year 2017 are made magnetic. Again, the faux ones are magnetic as well. Nevertheless, some appliances contain thin sheets of stainless steel over magnetic metal, which support magnets. However, it prevents the steel from holding magnets. Nickel, for example, in stainless steel, gives a sturdy structure. It implies why some are magnetic while some are not. They have various other metals mixed with them. Investigate the metals that make up this group of materials.Stainless steel appliances prevent magnets from sticking. What do you think is different about the metal items that stick to magnets compared with those that don’t? (They are all made out of the same kind of metal.)Įxplain to the students that there are certain materials that magnets stick to, namely ferromagnetic materials. Is there anything you noticed on your results list that is the same about all of the things that stick?Īre any metals in the “things that don’t stick” column? (aluminum foil) Instruct them to include any thoughts about items that acted in ways they didn’t expect.ĭid any of the items you tested surprise you? (Students may mention the aluminum or brass objects that didn’t stick to the magnet.) Students should compose a conclusion indicating which objects they were correct about in the hypothesis and which incorrect. Make a new list based on your results with columns labeled as follows:ī. Separate the objects into the two tubs based on whether they are attracted to the magnet or not. Remove the objects one at a time to test. Once all of the students (or groups) have composed their lists, tell students that it is time to complete the experiment and give each student a magnet. Students should separate the groups into the two tubs first and then make the lists. This should be done using a braillewriter for braille students so that this list can be easily accessed while looking at your results later.

Based on your experience in the past with magnets and the warm up activity, compose two lists of items. You’ll first be composing a hypothesis before testing the magnets. They might stick to a magnet or they might not. Introduce the bags to the students as follows: We will be looking at various objects in today’s lab. Question: Which items in the bag will stick to the magnet? More independent groups of students may work alone while younger students and less independent students should work as groups of two.

Give each student or lab group a bag full of common objects. Pick up the magnets before the following activity. Begin by having students determine what their magnet can stick to without leaving their seats.ĭiscussion: What did the magnets stick to? Share ideas about what is similar about the items that stick to the magnet

It may be necessary to gather enough braillewriters for the class if many of your students use braillenotes. Students should use braillewriters rather than braillenotes for this activity if possible. Try to include several metal items that do not have any iron (like aluminum foil).Ģ small tubs for each student group (I use the tubs from mushrooms.) – Prepare a bag of common objects for each group. Repel – to act with a force that drives something away Magnetic field – the area around a magnet in which magnetism can affect other objects Magnetic pole – one of the ends of a magnet where the field of the magnet is most intense Magnet – a substance which has a magnetic field and is able to attract iron and steel Please see review at In this activity, students discover what materials attract a magnet and which don’t. This simple yet elegant activity is adapted from the FOSS Magnetism and Electricity kit and book.
