Think Like an Engineer

What do engineers do when they have a problem to solve? They ask questions, imagine possibilities, build a model, test it, and improve the design. Children can practise the same process with simple household materials. Day 82 of the Solvera369 learning series introduces a friendly STEM challenge that makes engineering active, creative, and accessible.

STEM connects science, technology, engineering, and mathematics. In these activities, children predict what might happen, observe what actually happens, compare designs, and use evidence to decide what to change.

The Engineering Design Process

1. Ask: What problem are you trying to solve?
2. Imagine: Think of more than one possible solution.
3. Plan: Draw or describe your design before you build.
4. Create: Build a small model with suitable materials.
5. Test: Observe what works and what does not.
6. Improve: Change one feature and test again.

Challenge 1: Build a Tall, Stable Tower

Use paper, craft sticks, or drinking straws and tape to build a small tower on a flat surface. Predict whether it will stand, then test it gently. Notice the base, the balance, and where the structure bends. Try widening the base or adding supports. The goal is not simply to build the tallest tower; it is to learn why one design is more stable than another.

Challenge 2: Make a Paper Bridge

Place two books a short distance apart and lay a sheet of paper across them to make a bridge. With adult supervision, add a few coins or small blocks one at a time. Then try a new sheet folded into an accordion or a simple arch. Compare how the shapes behave and discuss why folds can make paper stiffer.

Challenge 3: Improve One Thing

Choose the tower or bridge and change only one feature. For example, widen the tower base, add a support, or change the paper folds. Test it again under similar conditions. Changing one feature at a time helps children make a clearer comparison and understand the relationship between design and performance.

Materials and Safety

• Use lightweight materials such as paper, straws, craft sticks, and tape.
• Have an adult supervise the activity and help choose age-appropriate materials.
• Avoid sharp tools, heavy objects, and small parts around children who may put objects in their mouths.
• Keep structures low, build on a stable surface, and stop if a structure becomes unstable.
• Clean up small pieces after the activity.

Questions to Encourage STEM Thinking

• What did you predict before you started?
• Which part of your design worked best?
• What happened when you changed one feature?
• How could you make the test fair?
• What would you try if you had another five minutes?

Mistakes Are Useful Information

A design that falls over or bends is not a failure; it is a chance to discover something. Encourage children to describe what happened without worrying about getting the first attempt right. With each cycle of building, testing, and improving, they practise persistence, reasoning, creativity, and clear communication.
