Bridge Building Experiment Concepts

Sam from Science Time guides children through fun experiments with bridges using household items. The video explores building bridges with paper, cardboard, and other materials, emphasizing the importance of shapes like arches and triangles for strength. Sam demonstrates how to conduct fair tests by changing one variable at a time and encourages viewers to experiment with different materials and designs. The session concludes with a call to share findings with Science Time.

What is one of the main reasons bridges are fun to experiment with?

• They are only found in cities.

• They are always very long.

• They are always made of metal.

• They come in various shapes and sizes.

What was the main issue with the initial paper bridge?

• It was too short.

• It was too wide.

• It was not strong enough.

• It was too colorful.

What shape was introduced to strengthen the paper bridge?

• Arch

• Rectangle

• Circle

• Square

Why are triangles considered strong shapes for building?

• They are easy to draw.

• They are very flexible.

• They distribute weight evenly.

• They are colorful.

What shape is a toilet roll, and why is it useful in bridge building?

• Triangle, because it is strong.

• Cylinder, because it can be used as a column.

• Rectangle, because it is long.

• Square, because it stacks easily.

What is a key difference between paper and cardboard when building bridges?

• Paper is more colorful than cardboard.

• Paper is stronger than cardboard.

• Cardboard wobbles less than paper.

• Cardboard is lighter than paper.

What is important to remember when conducting a fair test in experiments?

• Change everything at once.

• Only change one variable at a time.

• Use different materials each time.

• Test with different toys each time.

What was the result when more columns were added to the long bridge?

• The bridge fell down.

• The bridge wobbled a lot.

• The bridge became shorter.

• The bridge became stronger.

What can you do to test the strength of your bridge at home?

• Avoid using any toys.

• Only use small toys.

• Try different orders of toys.

• Use only one type of toy.

What should you do after conducting your bridge experiments at home?

• Only remember the failures.

• Record and share your findings.

• Keep the results a secret.

• Throw away the materials.
