Track matter while ice changes to liquid water

Connecticut Grade 5 science: compare scale readings during melting in a closed container, explain measurement limits, and find lessons and NGSS references.

The Connecticut science standards directory identifies the state’s adoption of NGSS on November 4, 2015. Use the publisher’s complete NGSS document for performance expectations and their examples and boundaries. This activity selects a Grade 5 expectation. It is one part of a science course, not a complete curriculum.

Has matter disappeared when the ice melts?

Place ice in a closed, lidded container and allow it to melt at room temperature. Weigh the whole closed container before and after melting on the same scale; keep the lid on for both readings. Include the same tray if a tray is used. Here is an invented pair of readings for discussion: 132 grams before melting and 132 grams afterward. These values illustrate the comparison; a class should record its own measurements rather than treat these as expected results.

Explain the evidence or model

The ice changes from solid water to liquid water, but the matter stays within the closed container. The equal readings support conservation of the total amount of matter measured in this system. Draw two bars at the same height and label both 132 grams, one “ice + container + lid” and the other “liquid water + container + lid.” The labels matter: weighing ice alone first and a container of water later would compare different systems. A change in shape, appearance, or the level occupied in the container does not show that matter vanished.

What to check in the explanation

If a real reading changes slightly, first examine the measurement. Was the lid included both times? Did water leak out? Is condensation on the outside adding water from the surrounding air? Is the scale stable, and what is its smallest displayed unit? Dry the exterior consistently and repeat the reading. Do not force children’s numbers to match the example. A scale has limited precision, so the conclusion should take the instrument and the container boundary into account. This lesson does not require a technical distinction between mass and weight.

Plan the next activity

  1. Draw a boundary around everything being weighed and label what is included.
  2. Record the starting reading and scale resolution, then let the ice melt without opening the container.
  3. Record the final reading, plot the two measurements, and describe what the graph shows.
  4. If readings differ, check the procedure and repeat measurements before explaining the difference.

Ask what would change if the container were left open for a long time. Water could leave that chosen system through evaporation; it would still exist elsewhere rather than cease to be matter. Students can mark a possible pathway across the boundary without needing to measure a tiny change in a short lesson. Use the conservation lesson next, and compare its explanation with the class’s actual record.

Connecticut Grade 5 Science: useful planning questions

How does Grade 5 connect to Connecticut’s science assessment?

Grade 5 is a Connecticut NGSS summative assessment grade. The state lists science assessments in Grades 5, 8, and 11. Resources here are independently published practice, not official state assessments or predictions of a state score. Read the official guidance.

Must two classroom scale readings be exactly identical?

Record the actual readings and the scale’s resolution. Check that the same closed system was weighed, that nothing leaked, and that exterior water was handled consistently. Interpret small differences alongside measurement limits rather than changing the data to match an example.

Where should I check the complete science requirements?

Start with the Connecticut science standards directory and the adopted NGSS document. Read the Grade 5 expectations and their boundaries alongside the school’s curriculum plan. The selected investigation and resources here do not certify complete course coverage. Read the official guidance.
