How much do you know about the Solar System? Do we live on a terrestrial planet, or on a gas giant? Which is biggest, Neptune or Venus? What is the Milky Way? Do this quiz to test how much you remember. The quiz is based on material from Chapter 1 of LinguaFrame’s textbook Biology and Geology – ESO 1.
2a Rocks and Minerals
This quiz is all about rocks and minerals. Do you remember the main properties of minerals, and of the three types of rock? What is the Mohs scale, and where do different minerals belong on it? The quiz is based on material from Chapter 2 of LinguaFrame’s textbook Biology and Geology – ESO 1.
3a Water
Most of the Earth’s surface is covered in water, and without water it would be impossible for us to live on the Earth. But why is there water on Earth? And how does it move from one place to another in the water cycle? Start the quiz to test how much you remember. The quiz is based on material from Chapter 3 of LinguaFrame’s textbook Biology and Geology – ESO 1.
4a Atmosphere
What do you know about the Earth’s atmosphere? Do you know the difference between the troposphere and the stratosphere? How was the atmosphere formed, and what is it composed of? Do this quiz to see how much you really know. The quiz is based on material from Chapter 4 of LinguaFrame’s textbook Biology and Geology – ESO 1.
4b Weather and Climate
What are thunder and lightning? Why is it sometimes sunny and sometimes cloudy? Do you know how atmospheric pressure affects the weather? This quiz is all about the Earth’s weather and climate.
5a Living Things
Animals, plants, fungi and bacteria are all alive. But what is a living thing, and why do we divide them into five kingdoms? And what are autotrophs and heterotrophs? In this quiz you can see how much you know about living things, and about the differences between the kingdoms.
6a Microorganisms
Microorganisms are the smallest living things, but how much do you know about them?. Do the quiz to find out.
7a Invertebrates
This quiz is all about invertebrates. Most of the animals in the world are invertebrates, but there are many different groups, with a variety of characteristics.

9a Plants and Fungi
This quiz will test how much you know about plants and fungi. Do you know the stem from the roots, and the carpel from the stamen? There are many kinds of plants, and they all have their own characteristics. Can you tell the difference between a flowering plant from a non-flowering one?
10a Ecosystems
The first part of this activity is a listening exercise about ecosystems, while the second part is about food chains and food webs. The questions are based on the material in Chapter 10 of LinguaFrame’s textbook Biology and Geology – ESO 1.
12a Volcanoes
This is an activity about volcanoes. It includes a listening exercise about Mount St. Helens.
