Scientific experiments add to knowledge and emphasise critical-thinking skills. Simple science projects are a platform for channelling students' natural curiously for making observations and forming conclusions. With a few household items and a checklist for the scientific method, children can experience being scientists. Whether it is for a school project or a family-time endeavour, the egg-bounce-with-vinegar project is easy and affordable.

Place a raw egg in the 1-cup plastic container. Pour white vinegar into the container so that the egg is completely submerged in the vinegar. Screw on the lid loosely. Keep the egg submerged in the vinegar for four days.
Write two hypotheses. Form one about what you think will happen to the egg while it is in the vinegar. Form the other about how high you can drop your egg before it will break.
Observe the egg each day and record your observations or data on your notepad.
Use a plastic spoon to remove the egg from the vinegar on the fourth day. Record your observation of the egg and compare this to your previous data.
Record whether or not your data proved or disproved your first hypothesis. Write your conclusion.
Drop your egg from various heights. Start at two inches and drop one inch higher each time. Check the egg after each drop for evidence that it has not broken during the drop. Record your data after each drop.
Stop the experiment when the egg breaks. Check to see if your data proved or disproved your second hypothesis. Write your conclusion.
