The ship appears to be able to float on water in numerous photographs. Have you ever seen a genuine ship on the water? Have you ever rode it before? What, in your opinion, makes ships float on water? Is it due to the ship’s modest weight? Let’s try this experiment to see why ships can float in water.
Tools and Materials of Simple Experiments; Floating Eggs in Water
- 1 raw egg
- 1 pcs glass or clear plastic jar
Instructions for Use of Simple Experiments; Floating Eggs in Water
- Prepare tools and materials
2. Put water into the glass until it is half filled
3. Add the eggs gently
4. Keep a watchful eye on what occurs.
5. Take the eggs from the glass and set aside in a safe place
6. Put 3 tablespoons of salt into the glass
7. Put the egg back into the glass
8. Re-observe what occurs to the egg, then season with salt and re-observe.
Explanation of Simple Experiments; Floating Eggs in Water
When placed in water, raw eggs with good conditions have a density greater than fresh water, causing the eggs to sink. When you add salt to the water, the mass of the water changes, causing the eggs to float. The higher the egg floats to the surface, the more salt you apply.
The egg has a watertight section and is totally filled with air, so as long as water does not enter the egg body, it will not sink. This is also consistent with what occurred with ships. Ships have an air-filled hull that prevents them from sinking as long as water does not penetrate that portion. Furthermore, the density of saline seawater makes it easier for ships to float on water’s surface.
Safety Instructions of Simple Experiments; Floating Eggs in Water
Because eggs are prone to cracking and are slippery when grasped, do it with parental guidance.
