Student Experiment: What Happens to Cut Apples Exposed to Oxygen?


What happens to the color of the inside of an apple that is exposed to the air (oxygen)?

That’s what first-grade students and teachers wanted to figure out, so they decided to check it out.

Teachers taught students to work through science inquiry – asking a question and coming up with a hypothesis.

Teachers cut the apples, and students observed over a two-week period what happened, while studying the effects of oxygen on the apples and discovered how the fruit changed during exposure to and after being exposed to the air. They also observed how the water (juice) evaporated from the apple over time – causing the apple to wrinkle and dry up.

The students drew the observations in their science journals during three separate class times throughout the experiment.

What scientists you are, first graders!
