Sink or Float Science Journal Experiment Worksheets Pre-K K

Turn a simple water test into an exciting science journey without preparation.

The Sink or Float Experiment Journal comes with 32 printable pages covering everything from prediction to reflection, including observing, recording findings, and understanding them all. Emphasizing hands-on science learning, the journal makes use of a childhood activity to make it a complete science experience that your students will never forget.

It is perfect for busy educators who want to ensure quality, standards-aligned science lessons without spending countless hours preparing lessons. Print and teach immediately!

WHAT'S INCLUDED (32 pages):

Science Vocabulary Sheets — Simple worksheets introducing terms such as sink, float, density, buoyancy, hypothesis, and prediction. Ideal for early elementary students.
Experiment Recording Pages (20+) — Detailed pages for predicting, observing, and reflecting. Everything children need to lead them through the entire experiment.
* Orange Mystery Experiment – An engaging buoyancy experiment using both peeled and whole oranges. Complete with observation sheets and discussion prompts.
* Critical Thinking Activities – Group items based on characteristics, weigh objects to determine which are heavy or light, and experiment with some practical cut-and-paste activities involving classification.
* Be the Scientist – Encourage students to choose their own materials, make predictions, conduct experiments, and document observations. The key is developing independence and confidence in scientific exploration.
* Data and Graphing Activities – Improve basic data handling skills through creating a simple bar graph and comparing class information.
* Science Discovery Certificate – Award certificate to recognize your young scientist’s efforts.
* Printer-Friendly – White pages designed to save ink and simplify printing.

PERFECT FOR

Science centers and STEM stations
Group science experiment and inquiry lessons
* Preschool and kindergarten science
* Science homeschool units
* Project-based learning science curriculum
* STEM summer camp
* Students who finish early
* Substitute science plans

SKILLS STUDENTS LEARN:

Make and record predictions
Observe and write observations
* Learn the concepts of buoyancy and density
* Collect and analyze basic data
* Expand science vocabulary
* Build science and engineering skills

STANDARDS ALIGNMENT:

Aligns with Next Generation Science Standards (NGSS) for kindergarten:
* K-PS2-1 - Plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.
* K-2-ETS1-1 - Ask questions, make observations, and gather information about a situation people want to change.

You will notice that this resource aligns with early science investigation skills that you can find in most states' science standards!

WHAT MAKES IT UNIQUE:

This is not your typical sink or float printable activity. Students get to follow the full scientific process by making hypotheses, testing those hypotheses, recording what happens, and finishing off by drawing conclusions of their own.
