With 80% of Australians living on the coast, for many of us seaweed are one of our neighbours! These incredible marine algae are vital to the survival of life on earth, helping produce up to 70 percent of the oxygen in our atmosphere and storing a quarter of the worlds carbon. In this virtual session, students will work with a Gardens educator to learn all about local seaweed species. By classifying and discovering how this living organism grows, survives and reproduces in its aquatic home, students will be inspired to take action and help save our coastal ocean habitats!
Group and classify seaweed
Discover the unique adaptations and lifecycles of a local seaweed species
Build scientific skills by accurately creating a Herbarium specimen and communicating their findings through formal representation
Consider how they can support the survival of seaweeds in their area

Please note: We have a minimum attendance for this session to run. If minimum attending numbers are not met, the session will be cancelled with 48 hours notice via email. A refund will apply in this instance.
If students are learning from home, they will need –
Own device with in-built microphone
If possible it would also be great if students could collect the following materials so they can follow along and prepare their own Herbarium specimen:
1 small piece of water colour paper (or plain white paper) cut to 10cm square in size
2 pieces of cardboard (approximately 10cm squared, cut from an old box)
1 rubber band
6 bits of newspaper cut to approximately 10cm sq in size
1 piece of Chux multi cloth (if available) cut to approximately 10cm sq in size
1 small piece of seaweed from your nearest beach or small branch or flower from the garden (no longer than 7cm in size)
a pencil or pen

The excursion will begin with an interactive presentation introducing what a seaweed is and why they are so important. This portion of the lesson will have students thinking about the coastal environments near them and the seaweeds that inhabit them.
The students will discover how to classify different types of seaweeds, the life cycle of a local seaweed called Codium fragile and the amazing interconnections seaweeds have with all the other living things found in rockpools, the ocean and the coastal environment around them.
Students will then explore the unique adaptations seaweeds have to live in the watery habitat, surviving crashing waves and surging tides and providing up to 70% of the oxygen in the earth’s atmosphere, something that is essential for our own survival!
Finally we will finish off building Scientific Skills by creating a personal Herbarium Specimen. Herbariums are like a warehouse of information about plant life. Plant samples are taken from the field by people with special collecting permits, then dried or preserved. These specimens, including information about them, are kept to learn more about the plants and their habitat. Today the students will learn to process of pressing, identifying and recording a species from their local area.
