How Much Water is in an Orange?
Easy
We're going to find out how much water is in an orange! We'll use a kitchen knife, paper plate, aluminum foil, and a weighing scale to measure the weight of the orange before and after drying it.
Hypothesis
The hypothesis is that there will be 50% or more water in an orange.
Method & Materials
You will weigh the orange, cut it into thin slices, spread the slices over the paper and aluminum foil, and keep it in a warm place until it is fully dry.
You will need an orange, a kitchen knife, a paper plate, aluminum foil, and a weighing scale.
Results
We found out that an orange is 81% water! This is an interesting observation because it shows that oranges are mostly made up of water.
Why do this project?
This science project is interesting and unique because it shows how much water is in an orange, which is something that many people don't know.
Also Consider
Experiment variations to consider include using different types of oranges, such as navel oranges or Valencia oranges, or using different drying methods, such as using a dehydrator or an oven.
