Solar still activity

In this activity students create a solar still and use a predict-observe-explain strategy to investigate how coloured salty water transforms into clear unsalted water. This activity is useful for exploring changes of state (evaporation and condensation) and water cycles.

Why is water sticky?

In this lesson sequence, students use a range of hands-on activities to explore what water is and how it behaves as it changes from ice to liquid water to water vapour. They explore the structure of water molecules and how these molecules behave when water is heated and cooled to help them to understand how the water cycle works.

Food innovation and molecular gastronomy lesson

In this lesson, students explore connections between science, design, and technologies through the lens of food innovation and food science. Students look at interesting and unusual food products, using food textures as a jumping off point to explore the relationship between chemistry and food. Students then experiment ...

Awake the mind with caffeine chemistry

Caffeine is the world's most popular drug, but what is it and how does our body respond to its presence? Watch this clip to see the chemical structure of caffeine and the three compounds it metabolises into. Find out which receptor in the brain caffeine binds to, and the overall impacts it has on brain function and activity.

Bromine monofluoride molecule

This is a colour image of a model of a molecule of bromine monofluoride, BrF. In this model, atoms are represented by coloured spheres held together by grey rods, representing covalent bonds. The bromine monofluoride molecule contains one bromine atom (the brown sphere) and one fluorine atom (the blue-grey sphere).

Hydrogen molecule

This is a colour image of a model of a molecule of hydrogen, H₂. In this model, two hydrogen atoms are represented by grey-white spheres held together by a grey rod that represents a covalent bond.

Image

Iodine molecule

This is a colour image of a model of a molecule of iodine, I₂. In this model, two iodine atoms are represented by deep red spheres held together by a grey rod that represents a covalent bond.

Image

Oxygen molecule

This is a colour image of a model of a molecule of oxygen, O₂. In this model, two oxygen atoms are represented by red spheres held together by grey rods that represent a double covalent bond.

Ethanol molecule

This is a colour image of a model of a molecule of ethanol, CH₃CH₂OH. In this model, atoms are represented by coloured spheres held together by grey rods that represent covalent bonds. The molecule contains two carbon atoms (the black spheres), one oxygen atom (the red sphere) and six hydrogen atoms (the grey-white spheres).
