NGSS Learning DimensionsThis Kid Spark lesson engages students in the following learning dimensions of the Next Generation Science Standards:

Scientific/Engineering Practice: Using mathematics and computational thinking

Crosscutting Concept: Scale, proportion, and quantity

Learning Objectives

Become familiar with the dimensions of an object including length, depth, and height.

Understand what components and objects look like from different points of view.

Calculate the size of Kid Spark engineering materials using the metric measuring system.

Become comfortable in the ability to use engineering materials to determine the dimensions of an object.

Building BasicsThe following tips will be helpful when using Kid Spark engineering materials.

Connecting/Separating ROK Blocks:

ROK Blocks use a friction-fit, pyramid and opening system to connect. Simply press pyramids into openings to connect. To separate blocks, pull apart.

Connecting/Disconnect Smaller Engineering Materials:

Smaller engineering materials use a tab and opening system to connect. Angle one tab into the opening, and then snap into place. To disconnect, insert key into the engineered slot and twist.

Snapping Across Openings:

Materials can be snapped directly into openings or across openings to provide structural support to a design. This will also allow certain designs to function correctly.

Attaching String:

In some instances, string may be needed in a design. Lay string across the opening and snap any component with tabs or pyramids into that opening. Be sure that the tabs are perpendicular to the string to create a tight fit.

Measuring:

The outside dimensions of a basic connector block are 2 cm on each edge. This means the length, depth, and height are each 2 cm. To determine the size of a project or build in centimeters, simply count the number of openings and multiply by two. Repeat this process for length, depth, and height.

Designing & Engineering in 3DAll objects that exist in physical space have three dimensions: length, depth, and height. Whether a given dimension of an object is classified as the length, depth, or height is determined by the perspective from which is viewed and measured.

These “dimensions” are identified as:

1. Length - How long the object is. 2. Depth - How deep the object is. 3. Height - How tall the object is.

InstructionsLocate a Green, Yellow, and Blue ROK Block to answer the following questions.

1. How many openings are there on the Length of the block? 2. How many openings are there on the Depth of the block? 3. How many openings are there on the Height of the block?

Understanding Multiview DrawingsIt is important to be able to understand what objects look like from different points of view. The primary views of most objects include the front view, the side view, and the top view. These views will give the length, depth, and height of an object.

Measuring with Kid Spark Engineering MaterialsKid Spark engineering materials are designed in metric units of measurement. This means that it easy to determine the dimensions of a object or design. Simply count the number of openings and multiply by two to determine dimensions in metric centimeters. On smaller engineering materials, there is a center mark in the middle of an opening that represents one centimeter.

InstructionsUse engineering materials to build two measuring sticks like the ones pictured below. Determine the length of each measuring stick in centimeters (cm). Then build a custom measuring stick to determine the dimensions of a desk, table, or object in the room. Make sure to measure length, depth, and height.

CleanupTo keep the ROK Blocks Lab clean and organized, students should have an understanding of how to correctly pack the lab once they are finished using it. Locate the ROK Blocks Inventory and Organization Guide that was included in the lab. Pack the lab back exactly as shown in the guide.
