Physical Science: Sink or float test
Written by Adi Ackerman, Head Teacher
"Physical Science: Sink or float test" is written for 1st Grade (Ages 6-7), and it covers NGSS 2-PS1-1. That standard sits in the 2nd grade band, so treat this worksheet as an early introduction rather than standards practice for this grade. If your little one is a year younger but already steady on material properties, the page still works. You may just need to read the instructions out loud. And if they are older and sink or float test never quite stuck, this is a short review rather than busywork.
1st grade science worksheet: Sink or float test. Circle float or sink to make a prediction. Then test each object in a tub of water and circle what happened. Part of our sink or float test material properties collection. Aligned to NGSS standards.
How do I use this worksheet?
Start with something students can look at or think about: a photo, a short video, a jar on the windowsill, or a question like "what do you already know about sink or float test?" Then let them work through the first item together as a class, then finish the rest independently or with a partner, keeping a word bank or anchor chart in view so the vocabulary stays available. When you review, ask students how they knew, and let them point to the part of the diagram or reading that told them. These sink or float test worksheets work well as a lead in before an investigation, as a way to capture what students noticed afterward, or as review before an assessment.

What does this worksheet teach?
⌄
These sink or float test worksheets for 1st grade give students a clear, visual way to work through one of the big ideas in material properties. Students label diagrams, sort and classify examples, read short explanations, and answer questions that ask them to say why, not just what. Each page keeps the science vocabulary front and center so students leave with the words they need to talk about sink or float test accurately. Working through sink or float test on paper gives 1st grade students something concrete to hold onto before, during, or after the hands on part of a lesson.
Can I use this sink or float test worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 1st Grade material properties, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with sink or float test. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.
