To design an electroplating kit for 5th grade learners, you would need the following equipment and sets:

1. Power Supply: A low-voltage power supply is required to provide a stable source of electricity for electroplating. You can use a battery pack or a small power supply unit (PSU).

2. Electrolyte Solution: You will need an electrolyte solution, which is a liquid medium that allows ions to move between the electrodes. Commonly used electrolytes for electroplating include copper sulfate, nickel sulfate, or silver nitrate.

3. Electrodes: You will require two types of electrodes—an anode and a cathode. Anodes are made of the metal you want to electroplate (e.g., copper, nickel, or silver), while cathodes can be any conductive material, such as a copper strip or a small metal object.

4. Electroplating Tank: A container is needed to hold the electrolyte solution during the electroplating process. You can use a plastic or glass container, ensuring it is wide and deep enough to accommodate your objects.

5. Connecting Wires: You will need wires to connect the power supply to the electrodes. These wires should have alligator clips or crocodile clips at the ends for easy attachment.

6. Safety Equipment: Ensure you have safety equipment, such as goggles and gloves, to protect the students while handling chemicals and working with electricity.

7. Objects to Electroplate: Finally, prepare the objects that the students will electroplate. You can use small metal objects like coins, keys, or nails. These objects should be clean and free from any dirt or grease.

It is essential to note that when working with electroplating kits, safety precautions must be observed, and adult supervision is recommended. It is also a good practice to emphasize the underlying science and explain the purpose and steps of the electroplating process to the students.
