A Challenge at the Science Museum

Read the challenge. Use the details to choose each answer.

Six Cubes, One New Model

At a science museum, visitors try a building challenge beside a robot display. A small model robot is made from six blue plastic cubes. Each cube is the same size. The cubes snap together. A museum helper gently pulls two joined cubes apart. Both cubes stay whole. The helper snaps them together again.

The challenge is to take apart the model robot and build a different model. Visitors may use the six cubes from the robot. They may not add cubes, break cubes, or leave any cubes unused. Two plan cards show choices: model steps and a model gate. Each cube picture on a card stands for one cube. After choosing a plan, visitors will build it and check their work. The helper puts an empty tray nearby to hold loose cubes.

What should a visitor do first to use the robot's cubes for a different model?

A. Turn the whole robot to face the other way.
B. Gently pull the robot's cubes apart.
C. Set the whole robot on a taller shelf.
D. Put a new name card beside the robot.

Select TWO details that show the cubes are suitable for taking apart and building again.

The joined cubes separate when gently pulled.The model sits beside a robot display.The separated cubes can snap together again.The tray is beside the building area.
