# Volume Container Block

> Learn how to use Volume Container blocks to create interactive liquid measurement displays.

The **Volume Container** block creates an interactive container that can be filled with liquid to demonstrate volume and capacity concepts. Learners can see the liquid level change and read measurements from graduation marks.

## When to use Volume Container blocks

Volume Container blocks work well for:

* Teaching volume and capacity measurement
* Demonstrating liquid measurement units (mL, L)
* Reading graduated scales and estimating volumes
* Exploring fractions and percentages of a total capacity
* Visualizing addition and subtraction of liquid amounts

## Settings

### Volume settings

<ParamField path="Total volume" default="1000" type="slider">
  The maximum capacity of the container (0 to 1000).
</ParamField>

<ParamField path="Initial volume" default="500" type="slider">
  The starting amount of liquid in the container (0 to 1000).
</ParamField>

<ParamField path="Volume unit" default="mL" type="text">
  The unit label displayed alongside the volume (e.g., mL, L, cups).
</ParamField>

### Display settings

<ParamField path="Show volume" default="true" type="switch">
  When enabled, displays the current volume as a number.
</ParamField>

<ParamField path="Show percentage" default="true" type="switch">
  When enabled, displays the fill level as a percentage.
</ParamField>

<ParamField path="Show graduation values" default="true" type="switch">
  When enabled, displays numeric labels alongside the graduation marks.
</ParamField>

<ParamField path="Show number sentence" default="true" type="switch">
  When enabled, displays a number sentence representing the current volume.
</ParamField>

<ParamField path="Graduation count" default="10" type="slider">
  The number of graduation marks on the container (1 to 100).
</ParamField>

<ParamField path="Liquid color" default="#0000FF" type="color">
  The color of the liquid in the container.
</ParamField>

## Tips for teachers and parents

**Best practices:**

* Start with a total volume of 1000 mL for standard metric measurement activities
* Use 10 graduation marks for easy reading, or increase the count for more precise measurements
* Hide the volume display to create estimation activities ("How much liquid is in the container?")
* Show the percentage alongside the volume to connect fractions, decimals, and percentages
* Change the liquid color to match the context of your activity (blue for water, orange for juice)
* Use multiple containers side by side to compare volumes
* Change the volume unit to match your local measurement system
