About this resource
Make learning about apples fun with this apple science experiment. Students will practice making predictions, conducting an experiment, and recording their results with this apple sink or float experiment.
What is Included:
There is a detailed instructional page that provides detailed instructions for the experiment, a materials list needed, and any special tips or optional activities to complete with this experiment.
There is a recording page with easy to follow directions for students to draw or colour their predictions and record the results of the experiment.
There are two journaling pages students can use to record their results and write about what they observed during the experiment. One journal page includes picture clues to guide students in their responses, while the other is a simple journal page for students to draw whatever they wish and then write their responses.
What is the Experiment?
This experiment is an apple sink or float experiment. Students will use a whole apple as well as different parts of an apple to see if they sink or float in a bucket of water. This experiment allows students to learn about buoyancy.
How to Use:
Students can work in small groups of 2 or 3 to complete this experiment. The teacher may also choose to lead the experiment with the whole group of students. Each method allows students to make predictions and record results on their own.
This science experiment is perfect for young learners. The easy to follow instructions and scaffolded recording and journaling pages help students through completing the experiment.
While setting up the experiment does take material and time to do, the recording pages and journaling pages are no-prep, making this an easy activity to prepare for students. The low prep experiment is a great addition to any busy classroom or home school environment.

Teaching tips & learning objectives
Learning objectives
Predict whether different parts of an apple will sink or float in water.
Test each prediction through a hands-on experiment and record the actual result.
Compare a prediction to an observed result and explain in writing why an object sank or floated.
Teaching tips
Pre-slice the apple ahead of time to speed up the experiment during class, as the directions themselves suggest as an option.
Run the experiment in small groups of 2-3 students, or lead it as a whole-group demonstration, since the directions note either approach still lets each student make individual predictions and record results.
Have students complete their prediction column on the recording sheet in full before testing any apple part, so the Yes/No 'Was I right?' column reflects a genuine before-and-after comparison rather than a guess made after seeing the result.
Skills covered
Predicting — students record a sink-or-float prediction for each of six apple parts before testing.
Observing and recording — students test each apple part in water and record what actually happened.
Comparing prediction to result — students mark whether their prediction was correct for each apple part.
Explaining findings in writing — the journal page has students describe and explain why each piece sank or floated.
Good to know
Questions teachers ask about this resource
Can this experiment be done in small groups, or does it need to be teacher-led?
Both work. The directions support running it in small groups of 2-3 students with the teacher supervising, or leading it as a whole-group demonstration while each student still records their own predictions and results.
Does the experiment test just a whole apple, or different parts of it?
Different parts. Students test a whole apple, half an apple, an apple slice, the peeled flesh, the peel, and a seed, recording a separate sink-or-float prediction and result for each.
