Step 1: Unit 5 Lesson 7

| Problem | Solution That Uses a Magnet | How Do Magnets Solve the Problem? | |----------------------------------|------------------------------------|------------------------------------------------------------| | Hanging a picture on the wall | Use a magnetic picture hanger | Magnets allow the picture to hang securely without damaging the wall. They attract the metal surface of the hanger. | | Organizing metal tools | Magnetic tool holder | The magnetism pulls and holds metal tools in place, preventing loss and clutter. | | Keeping notes on the fridge | Magnetic memo holder | The magnetic force attracts the holder to the fridge, allowing easy access to notes. |

Step 2: Unit 5 Lesson 8

Question 1: How does a doorbell solve a problem?
Answer: A doorbell serves as a signal for someone at the door, allowing the homeowner to know when visitors arrive without being in the same room.

Question 2: Think about a problem. It could be at your home. It could be in the world. How could you use magnets to solve the problem?
Answer: A common problem is organizing cables and wires. I could use magnets to create a cable organizer that holds wires in position without tangling.

Question 3: Design the solution. Write it down.
Answer: Create a board with strips of magnets attached. The wires can be held in position by magnetically attracting them to the strips, which reduces clutter and tangling.

Step 3: Unit 5 Lesson 9

1. A problem is identified: tangled wires.
2. Research was conducted on using magnets for organization.
3. Materials were gathered: a magnetic board and cables.
4. A design was drafted for the magnetic cable holder.
5. The cable holder was constructed and tested.
6. Feedback was collected on its effectiveness.
7. Adjustments were made based on the feedback.

Were you able to solve the problem using a magnet? If not, give possible reasons.
Answer: Yes, the magnet solution effectively organized the cables, but some heavier cables did not stay in place as well as lighter ones due to insufficient magnetic force.

Step 4: Unit 5 Lesson 10

Question 1: Think about the problem you worked on in the last lesson. Suppose the solution didn’t work. What could you do to improve it?
Answer: To improve the solution, I could use stronger magnets or add additional magnetic strips to accommodate heavier cables. This would help in increasing the pull force and keeping all cables secure.

Question 2: If your solution did work, can it be improved?
Answer: Yes, while the solution worked well, I could enhance its design by adding labels to the cables for better organization and making it easier to identify each cable's purpose.

Question 3: Present your work to a friend or family member. Show them your work. State the problem. Tell them your solution. Show how magnets solve the problem. Who did you present your problem to and what did they think?
Answer: I presented my work to my sister. I explained that tangled wires create chaos and my solution was to use magnets to hold them in place. She was impressed and suggested adding color coding to improve the organization even further.
