LEARNING SITUATION CHALLENGES THAT LEAVE AN IMPRINT

Learning Sequence

RESEARCH GROUPS.

1.1 Get into groups of 4 or 5.

1.2 The first challenge is to brainstorm ideas about what a volcano is. In your group, create a mind map to show everything you know about this natural phenomenon. Try to answer the following questions: What does a volcano have to do with physics and chemistry?

• Are there any pure substances or mixtures in lava?

Next, research on the Internet how people are working to improve the quality of water in your city, or measures they are taking to reduce the amount of pollution in lakes, rivers or oceans. Finally, look up targets 6.1 and 6.3. How do they relate to the images and your research?

Writing

In the history of science, even though a person was on the right track to find something meaningful, many times other theories and ideas imposed on the correct one. For instance, when Gregor Mendel (1822-1884) explained how the laws of genetic inheritance work, nobody listened to him and he died without being recognised. It wasn’t until the next century that his ideas were accepted.

The following shows other three similar cases. Use the word prompts to create sentences that describe the ideas of each of them. In each case, you must write at least two sentences in past simple by conjugating the underlined verbs in that tense.

1 Ignaz Semmelweis, handwashing, discover, infection, doctor, hospital, reduce.

2 Gregor Mendel, inherit, experiments, plants, peas, carry out, genes

3 Aristarchus, the Sun, mathematician, the Earth, is, orbit, propose

• What properties of matter do the materials expelled by the volcano have?

WHAT COMES OUT OF A VOLCANO?

It’s time to organise your ideas and search for any missing information.

• What is a volcano?

• What does a volcano expel?

• Is the material in solid, liquid or gas form?

• What happens when the mass of magma reaches the sea? Have you heard of neutralisation?

• What is the chemical composition of lava?

• What about gases? What gases does a volcano expel?

Do some research.

SCIENTIFIC POSTER.

Use the online tool to create a poster to explain your model. Create an outline with all the information from activities 1 and 2. Don’t forget that the information has to be related to the volcano you are going to design.
