Web Strength Unraveled

Science · 30 min · Any age · You and your child together

This Spark challenges curious minds to discover the incredible strength of spider webs by testing everyday materials. Children will design their own experiments, explore the concept of tensile strength, and uncover why a tiny spider's silk is an engineering marvel.

What your child gets out of it

• Predict and test the strength of different materials.
• Understand the concept of tensile strength.
• Compare the strength of everyday items to natural materials like spider silk.

What you need

• Various thin strings or threads — Gather a few different types to compare their strength. (or Dental floss, Fishing line, Yarn, Sturdy sewing thread, Shoelace, Even a single strand of hair)
• Small weights or objects — You'll need a way to gradually add weight to test strength. Aim for at least 10-15 similar, light items. (or Paperclips, Coins, Small toy blocks, Washers)
• Ruler or measuring tape — To ensure you use similar lengths of your 'super strings'.
• Scissors
• Tape — To secure your string during testing, or to hold weights. (or Clothespins, Binder clips)
• Yarn
• Dental floss
