Fluffy Bee

Did you know the first bees would have been flying around in the Cretaceous just as ‘Iggy’ our Iguanodon was snacking on leaves from tall trees? At the Sedgwick Museum we have two 20million year old honey bees trapped in amber. Found on Yarmouth beach in 1891.

Amy Smith studies bees Plant Sciences in Cambridge. In this activity Amy shows us how to make a bee-autiful fluffy bumble bee. You will need some card and wool. 

Vinegar Volcano

Volcanoes form when hot molten rock (magma) under the ground erupts at the surface, but what causes the molten rock to erupt? Eruptions are often driven by gases escaping…

In this experiment you can start a chemical reaction that creates a gas, and see how the gas escaping drives an eruption.

This experiment and video was devised by the Volcano Seismology group in the Earth Science Department, University of Cambridge.

Bubble escape and drag race

There are many different types of volcanoes. Shield volcanoes have a broad rounded shape and gentle splattery eruptions often described as fire fountains. Strato volcanoes are sharp and steep sided and have violent explosive eruptions. But what makes these two types of volcano look and erupt so differently? It is mainly controlled by how think (viscous) or runny the magma in the volcano is...

In this experiment you can use 3 different thickness (viscosity) liquids to see what differences runny or thick magma can cause in volcanoes.
