What happens when an apple is cut and left out? This apple oxidation experiment gives Pre-K and early elementary students a simple way to observe what happens when apple slices are treated with different liquids.
Students will compare apple slices treated with salt water, vinegar, water and lemon juice to an untreated apple slice. After soaking the apples for five minutes, students will observe them over time to see which ones turn brown and which stay looking fresh.
This experiment is designed specifically with younger children in mind. Rather than getting into the more complex science behind why certain liquids slow down browning, the focus is on observing, predicting, comparing and talking about what students notice. Children can even explore how the color and texture of the apples change over time.
The experiment can be completed in one school day or extended overnight for an even more noticeable comparison.
Included:
- Easy-to-follow experiment instructions
- Apple treatment labels
- Student observation recording sheet
- Two observation opportunities
A simple, hands-on addition to an apple theme, fall science center or preschool science lesson!
