Let's solve each riddle one by one based on the descriptions provided in the "Creative Lab" worksheet.

Riddle 1:
> I am a laboratory equipment with a flat bottom. I also have a conical body and cylindrical neck. I have a beaded mouth which means that a stopper can be placed into it. Who am I?
Analysis:
- Flat bottom → allows it to sit stably on a surface.
- Conical body → narrows toward the top.
- Cylindrical neck → straight tube-like top.
- Beaded mouth → has a ridge (bead) at the opening so a stopper fits snugly.
This is a classic description of an
Erlenmeyer flask (also called a conical flask). It’s commonly used in labs for mixing, heating, or storing liquids.
✔ Answer: Erlenmeyer Flask
👉 Draw: A flask with a wide base (conical), narrow neck, and a small bead around the rim where a stopper can go.

Riddle 2:
> I am a laboratory equipment that produces some kind of an invisible field. I can pull materials made of iron, steel, nickel, cobalt, and many more. I can attract or repel my siblings depending on which side I am facing. Who am I?
Analysis:
- Produces an invisible field → magnetic field.
- Pulls iron, steel, nickel, cobalt → these are magnetic materials.
- Attracts or repels other similar items → opposite poles attract, like poles repel.
- “Siblings” likely refers to other magnets.
This describes a
magnet.
In a lab setting, magnets are often used to separate magnetic materials, hold objects, or in experiments involving magnetism.
✔ Answer: Magnet
👉 Draw: A bar magnet or horseshoe magnet with labeled north and south poles.

Riddle 3:
> I am a laboratory equipment with a pear-shaped body. I also have a flat bottom and my neck is elongated yet narrow. Who am I?
Analysis:
- Pear-shaped → wider at the bottom, tapering upward.
- Flat bottom → stable base.
- Elongated narrow neck → long and thin top.
This is a
volumetric flask. It is used to prepare solutions of precise volume. The pear shape helps with mixing, and the narrow neck allows accurate volume marking.
✔ Answer: Volumetric Flask
👉 Draw: A flask that is wide at the bottom, tapers up, has a long thin neck, and a flat bottom. Often has a calibration mark near the top.

✔ Final Answers:
1.
Erlenmeyer Flask
➤ Draw: A conical flask with a flat bottom, cylindrical neck, and beaded rim.
2.
Magnet
➤ Draw: A bar or horseshoe magnet with poles marked (N and S).
3.
Volumetric Flask
➤ Draw: A pear-shaped flask with a long narrow neck and flat bottom.
