Question

What provides an electric current in an electromagnet?(1 point) Responses battery battery wire wire paper clips paper clips iron or steel core
Answer
Students built two electromagnets. The electromagnets are the same except that one has 20 wire coils around its core, and the other has 40 wire coils around its core. Which is the best comparison?(1 point) Responses The electromagnet with 20 coils will be stronger than the electromagnet with 40 coils. The electromagnet with 20 coils will be stronger than the electromagnet with 40 coils. The electromagnet with 40 coils will be stronger than the electromagnet with 20 coils. The electromagnet with 40 coils will be stronger than the electromagnet with 20 coils. The electromagnets will be equally strong. The electromagnets will be equally strong. The electromagnet with 40 coils will be exactly twice as strong as the electromagnet with 20 coils.
Answer
Samuel builds four electromagnets and tests them by picking up paperclips. Here are his partial results. Coils Paperclips 8 2 16 7 24 11 30 ? Which is the best prediction for the number of paperclips the electromagnet with 30 coils will pick up? (1 point) Responses 1 paperclip 1 paperclip 8 paperclips 8 paperclips 11 paperclips 11 paperclips 14 paperclips
Answer
Which scenario describes how students can work together creatively to explore electromagnets?(1 point) Responses Three students research an electromagnet in their science textbook. They then build an electromagnet exactly like the one in their textbook. Three students research an electromagnet in their science textbook. They then build an electromagnet exactly like the one in their textbook. Three students research different electromagnets at the library, then communicate what they have learned to one another. Three students research different electromagnets at the library, then communicate what they have learned to one another. Three students follow the directions of their teacher for building an electromagnet. Three students follow the directions of their teacher for building an electromagnet. Three students independently research and build their own electromagnet.
Answer
You are working with a team to improve an electromagnet. Which is an effective way to communicate your ideas?(1 point) Responses Tell other students that their ideas for improving the electromagnet won’t work without offering solutions. Tell other students that their ideas for improving the electromagnet won’t work without offering solutions. Build your own electromagnet and then tell other students how you did it. Build your own electromagnet and then tell other students how you did it. Listen to other students’ ideas and follow their suggestions for improving the electromagnet, without adding any input yourself. Listen to other students’ ideas and follow their suggestions for improving the electromagnet, without adding any input yourself. Listen to other students’ ideas, then get their attention and clearly explain your ideas about how to improve the electromagnet
