Super Spider Facts and a Sticky Web Science Activity

Whether you love them or loathe them, spiders are hugely essential creatures. Without spiders, there would be a LOT more insects eating our crops, which would seriously affect our food supply.

Spiders are invertebrates ( they have no backbone ). The biggest group of invertebrates are arthropods, including spiders. Arthropods are further subdivided into other groups, including arachnids and insects. Spiders are arachnids!

Super Spider Science - make your own sticky spider web

This very simple science activity illustrates how insects stick to spider webs. Spiders produce a sticky substance, so their prey gets stuck in the web. We can't make a web like a spider, but we can make our own version.

This is a great activity for learning about how different materials have different properties and starting to understand a spider's place in food chains.

You'll need

Hula hoop

Different types of sticky tape - duct tape, sellotape, masking tape

Small light items such as pom poms, strips of wool and ribbon, small plastic insects

Instructions

Stretch two or three different types of tape across the hula hoop and fix them securely in place.

Gently throw small items towards the web and record how well they stick on each type of tape.

Was the stickiest tape the one you expected?
