Nelson Rural: Amber, Kate, Chase and Jaden. Purpose- How much salt does it take for an egg to float in water?

Hypothesis- We predict the egg will float after 30 ml of salt is put into the water.

Porcedure- Step 1: Weigh an empty beaker. Step 2: Add water into the beaker and measure it. Step 3: Subtract the weight of the beaker from the weight of the water. Step 4: Add the egg into the water. Step 5: Add salt( by 10 ml) into the beaker until egg is floating at the top. Step 6: Record your observations.

Analysis- When we first put the egg in the beaker of water the egg went straight to the bottom. When we begun to add the salt the egg gradually raised. After around 20ml of salt the egg was floating near the middle of the beaker. Once we added about 20 more ml the egg was floating at the top of the beaker and could be seen out of the water.

Conclusion- When we did our experiment to see how much salt is needed for an egg to float in water we came to the conclusion that our hypothesis was incorrrect, we predicted that it would take 30 ml of salt for the egg to float but it actually took 40 ml. When we began our experiment the egg was completely floating at the bottom of the beaker, when we added salt the egg gradually began to float to the top, when we finally added the 40th ml the egg was completely floating at the top of the beaker. We this happened because the salt made the water more dense making it easier for the egg to float on the water.
