About this worksheet

What students practice

Students use observations to model air as matter made of particles too small to see.
Students develop and revise particle models showing air moving between places.
Students use particle models and evidence to predict how trapped air affects water movement.

How to use

Read the investigation and graph together. Have students evaluate and draw particle models, then use their models to predict a new test.

Farm Irrigation Bench: Predict the Bubbles

Use evidence and particle models to predict where air and water will go.

1. Follow the Irrigation Investigation

Read the investigation. Use the observations and graph to explain what happened.

A Cup in the Farm's Water Trough

At a farm's irrigation repair bench, workers sometimes notice bubbles when they lower an empty hose into water. A visiting fifth-grade group wondered what the bubbles could reveal about matter they could not see. Their farm guide, Nia, helped them investigate with a clear plastic measuring cup and a shallow trough of clean, room-temperature water. The samples were not for drinking.

Step 1: The group checked that the cup was dry inside. It could hold 250 milliliters up to its rim. A student turned the cup upside down, with its opening facing down, and slowly lowered it straight into the water. The rim stayed level and just below the surface. The cup's clear sides allowed the group to watch its inside.

Step 2: The student held the cup steady. To the nearest 25 milliliters, the group measured no water inside it. Water surrounded the cup outside. The students could see through the cup, but they could not see anything moving in the space inside it. They recorded this as the 'Held level' stage.

Step 3: The student slowly tilted the same cup. Bubbles rose from its opening, and water entered. The student paused when the cup held 125 milliliters of water. The group recorded this as the 'Partly tilted' stage. The cup was not squeezed, and no material was added.

Step 4: The student continued turning the cup until its opening faced up underwater. More bubbles rose. Water filled the cup to its 250-milliliter rim. This was the 'Opening up' stage. Throughout the test, the group used the same cup, trough, water, and measuring marks. They changed the cup's position and measured how much water entered.

The group then planned particle models. In a particle model, drawn symbols represent pieces of matter too small to see with our eyes. One symbol may represent many particles. A key identifies what the symbols represent. The drawn sizes, shapes, and spaces are not photographs or measurements of real particles.
