Explore 30 worksheets related to sink or float worksheets currently available in our library. Sink or float worksheets help young learners predict, test, observe, and record what happens when safe objects are placed in water. These printable science activities include picture-supported predictions, sink-or-float sorting, hands-on experiment sheets, observation charts, prediction-and-result comparisons, repeated tests, tallies, picture graphs, evidence questions, independent practice, review, and assessment for Pre-K, Kindergarten, and 1st Grade.
Sink or Float?
Young learners make simple predictions about eight familiar objects by choosing whether each might float or sink before testing.
Will It Sink or Float?
Students predict whether ten familiar classroom objects will sink or float, with a reminder that testing is needed to find out what actually happens.
Sink or Float Picture Sort
Children cut and sort 12 object pictures into predicted FLOAT and SINK groups before a real teacher-supervised water test.
Make a Prediction
Students draw or name eight teacher-selected objects and record a FLOAT or SINK prediction before testing them in water.
Test It in Water
Children test six teacher-selected safe objects in water and record whether each object actually floated or sank.
Predict and Test
Students make predictions for six objects, test the same objects, record the observed results, and compare prediction with outcome.
Sink or Float Observation Chart
Students use an eight-row investigation chart to record each object, prediction, observed result, and a short note or drawing.
What Happened?
Students read eight clearly illustrated completed water tests and identify whether each specific object floated or sank from visible evidence.
Float or Sink Results Sort
Students sort 12 completed-test result cards into FLOATED and SANK groups using the water-test evidence shown on each card.
Prediction and Result Match
Students compare eight recorded predictions with pictured test results and decide whether each prediction and result are the same or different.
My Sink or Float Experiment
Students complete a guided five-object sink-or-float investigation with drawing, prediction, testing, results, and simple result totals.
Draw Something That Floated
Children draw one object that floated and one that sank based on the results of their own class investigation.
Find Objects to Test
Students choose eight safe classroom objects they would like to test and record a FLOAT or SINK prediction for each one.
Sink or Float Science Center
Students follow a simple Predict-Test-Record science-center routine for six safe teacher-selected objects with minimal writing.
Sink or Float Tally
Students use results from a fictional 12-object experiment to tally floated and sank outcomes and answer four simple count questions.
Sink or Float Picture Graph
Students interpret a two-category picture graph showing FLOATED and SANK results and answer five questions about counts and comparisons.
More Floated or Sank?
Students compare six small experiment records and decide whether more objects floated, more sank, or the results were equal.
Compare Two Tests
Students compare two six-object sink-or-float test records and answer six questions about floated and sank totals.
Same Object, New Test
Students compare two repeated tests of the same object in six examples and decide whether the observed results are the same or different.
Test It Twice
Students predict once, test four teacher-selected objects twice, and compare the two observed results for each object.
Does Size Tell Us?
Students examine six paired fictional tests and use the supplied results to see whether visual size alone correctly predicts sink or float every time.
Look at the Results
Students read eight fictional sink-or-float records containing an object, prediction, and result, then answer one evidence-based question for each record.
Sink or Float True or Not?
Students evaluate ten picture-supported TRUE or NOT TRUE statements about predicting, safe testing, observing, recording, and comparing results.
Sink or Float Evidence
Students use eight pictured water tests to choose the statement supported by visible evidence and distinguish observation from unsupported explanation.
My Sink or Float Investigation
Students complete a four-object investigation record with prediction, result, drawing, observation notes, and totals for floated and sank objects.
Sink or Float Practice 1
Students complete 16 mixed practice items covering prediction, result reading, prediction-versus-result comparison, and simple floated-versus-sank counts.
Sink or Float Practice 2
Students complete 16 new sink-or-float practice items with different objects, result illustrations, answer sequences, and simple comparisons.
Sink or Float Mixed Review
Students review sink-or-float skills in four sections covering predictions, supplied results, prediction-result comparison, and simple tally or graph data.
Sink or Float Challenge
Students complete 12 stronger questions using prediction-result comparisons, experiment records, repeated tests, counts, and visible evidence.
Sink or Float Check-Up
Students complete a 16-item final assessment covering predictions, observed results, comparisons, repeated observations, and simple experiment data.
FAQs About Sink or float worksheets
An object floats when it remains at or near the surface of the water during a test, while an object sinks when it moves down through the water and rests lower in the container.
Students can make a prediction, place one teacher-approved object in a container of water, observe what happens, and record whether that specific object floated or sank.
Yes. Making a prediction before testing gives children something to compare with the result and helps them practice early science thinking.
Yes. A prediction is what a student thinks might happen before testing. The important part is observing the actual result and recording what happened.
No. Simple size or weight rules do not reliably determine every result. Early learners should test specific objects and use the observed results as evidence rather than rely on one appearance-based rule.
Students can record the object, their prediction, whether it floated or sank during the test, a drawing of what happened, and simple totals or comparisons.
