Are you looking for an easy prep winter science experiment? You probably already have these inexpensive supplies. Dangling ice on a string is an engaging lab that teaches the scientific method and freezing and melting points.

Students will use the scientific method to investigate how salt affects ice. The students will test if the amount of salt will affect the ability of a piece of string to pick up an ice cube. They will identify the independent and dependent variables, write a hypothesis, follow procedures, record observations and data, create a graph, and write a summary. By the end of this investigation, the students should understand that salt lowers the freezing point of ice. It is great for the winter season.

Teachers will love its' ease of use and simple supplies. They will enjoy watching the students hold the ice cube with the string. We used it for family science fair workshops, and the parents and students loved it.

Supplies needed: cup or Mason jar, ice cubes, salt, string, water, time

Included in the Hands-On Investigation and Teacher Guide:

  • Background Information
  • 6 Page Investigation Journal written at the student’s level
  • Rubric
  • Answer Key
  • Terms of Use

This investigation is great for a classroom, homeschool lesson, or a science fair project.

Digital and Distance Learning Approved. This is a great way to get students to use the scientific method at home. The supplies are simple and can be modified with what students have on hand. The file is a PDF but comes with a pre-created Easel by TpT overlay. We added text boxes and tips for completing it online. Click "Open in Easel" on each product page to get started. They can be added to your Google Classroom as an assignment. Students can also print and complete it. A science lab teacher can also assign all the grade levels, allowing families to conduct the experiment together.(See the Bundle.) You can send the overlay as a link to Google accounts if you don't have Google Classroom. If that is not possible, use the PDF in a program like Kami extension to create an online version with text boxes. We already did it for you in Easel. You could conduct the experiment as a demo for the students, and then they try it. Get creative!

This investigation is part of a series. The kindergarten and first graders focus on 1 trial and only one change. The 2nd/3rd-grade version takes it up with 3 changes, 1 trial, and more writing. The 4th/5th/6th-grade version expands by providing 3 levels, performing 3 trials, and calculating the mode. More writing is expected.

Make observations and measurements to identify materials based on their properties. Examples of materials to be identified could include baking soda and other powders, metals, minerals, and liquids. Examples of properties could include color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, and solubility; density is not intended as an identifiable property. Assessment does not include density or distinguishing mass and weight.
Develop a model to describe that matter is made of particles too small to be seen. Examples of evidence could include adding air to expand a basketball, compressing air in a syringe, dissolving sugar in water, and evaporating salt water. Assessment does not include the atomic-scale mechanism of evaporation and condensation or defining the unseen particles.
