Live Events

Live investigations


Putting into practice ‘working scientifically, Digital Explorer run seven live investigation sessions. The age-differentiated investigations run twice daily in the morning and in the afternoon. Students either actively participated by doing the investigation at the same time as the live broadcast or joined in by submitting their questions.

Monday, 29 October: Introducing corals

Wednesday, 31 October: The coral habitat 

  • Coral food chain mobile (ages 6+) introduces young people to a range of living things and animals on the coral reef and how they are connected. Through this food chain activity young people are introduced to some of  animals that they may come across during a coral expedition (30 mins).

Friday, 2 November: Coral in a high CO2 world

  • Ocean acidification in a cup (ages 10+) illustrates how the increase in carbon dioxide in the ocean is lowering pH levels, thus impacting marine life. This activity shows how water becomes more acidic when carbon dioxide is bubbled through it. It demonstrates the link between carbon dioxide in the atmosphere and a process called ocean acidification, a change in the pH, or acidity, of the ocean (15 mins).
  • Dissolving ‘coral’ and ‘shells’ in vinegar (ages 10+) demonstrates the ability of an acidic substance (i.e. vinegar) to ‘dissolve’ coral reefs and shells which protect ocean life. Although corals and shells are not dissolving as fast as demonstrated in this experiment, it is possible to reach these levels in the future (10 mins).

Tuesday, 6 November: Going deeper

  • Under pressure (ages 10+) shows the relationship between water depth and pressure such as when your ears pop when swimming into water (15 mins).

Thursday, 8 November: Adaptation on the reef

  • Streamlined sharks (ages 8+) asks students to investigate the relationship between shape and water resistance, answering the question ‘What is the best shape for a shark?’. Sharks haven’t evolved much for the past 100 million years. Is there a reason for this? This investigation will be followed by a discussion of what would make the ultimate coral animal with students tasked to ‘design’ their own.
