## Interactive Measurement Practice

As we begin the school year in the wake of Covid-19, traditional labs and hands-on activities are very limited. Therefore, we need to find ways to do things virtually. I developed this interactive measurement & scale-reading activity using Construct 3. Students can use this to practice reading the scale on a ruler and reading the volume in three different-sized graduated cylinders.

### Length Measurement Features

- Draggable ruler
- Checks accuracy of measurement and provides feedback.
- Accepts measurements within ±0.015 cm of the actual length.
- Provides encouragement to estimate as accurately as possible for measurements within ±0.03 cm of the actual length.

- Requires input of units (cm) for each measurement.
- Challenges users to measure five lengths in a row. Any mistakes will cause the count to start over.
- Button to download a screenshot when finished.

### Volume Measurement Features

- Practice reading scales on 500-ml, 100-ml, and 10-ml graduated cylinders.
- Checks accuracy of measurement and provides feedback.
- Accepts a small range of estimates for the final digit in the reading.
- Requires recording volumes to the level of precision/resolution of the graduated cylinder.

- Requires input of units (ml) for each measurement.
- Requires users to correctly measure 6 volumes to complete the activity (2 for each of the cylinder sizes).
- Button to download a screenshot when finished.
