Plants

This issue of Big Picture provides lots of interesting information about flowering plants and their uses. 

The plant hormones animation explores the action of indole-3-acetic acid (IAA) and shows how scientists used experimental evidence to explain the role of auxins in a phototrophic response.

Surveying populations

This animation demonstrates the range of methods that can be used to investigate different populations in a woodland ecosystem.

Light sabers presentation and experiments

Presentation on science of lightsabers and comparing them to lasers and plasma torches. Looking at uses of lasers. Experiments on light and colours

Populations

What’s the first thing that pops into your mind when you read the word population? Most likely it’s the ever-increasing human population on earth. The term population isn’t just used to describe humans; it includes other animals, plants and microbes too. These resources will help you learn more about how...

Sliding filament theory

This animation shows muscle contraction and the sliding filament theory

The involvement of cells in hearing

This animation shows how cells enable us to hear.

What’s up buttercup? Population sampling techniques

This video demonstrates population sampling techniques by investigating whether the number of buttercups in our chosen field differs from the top of the hill to the bottom.

How IAA, the most common form of auxin, works

This animation explores the action of indole-3-acetic acid (IAA), the most common form of auxin, and looks at how scientists used experimental evidence to explain the role of auxins in a phototrophic response.

Do we favour fatty foods?

Watch our short film, in which we conduct a curry-tasting experiment, and then use the data generated to test whether the findings are statistically significant

Fat

Fat is a word that carries a lot of weight, conjuring up topics as diverse as obesity, hibernating animals, and what we eat and how we cook it. This issue of the Big Picture looks at the fats and lipids to find out what they do, not just inside us and other organisms but also in the world around us.  Curriculum...
