Seaweed Science – Stages 2 & 3

Live Event
05
Oct

With 80% of Australians living on the coast, for many of us seaweeds 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!

Students will

  • 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

Cost: $100 for 1 class up to 30 students/$175 for two classes up to 60 students/ $225 for three classes up to 90 students. Additional classes up to 30 students are charged at $50 per class

Capacity: 300 students per session

Instructions

Requirements for this excursion

If students are learning from home, they will need – 

Internet connection
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

If you are dialling in from the classroom, you will need – 

A microphone so the presenter can hear the class. Please note that some laptop microphones are difficult to hear, and the positioning of the laptop is important for capturing sound.
A projector or smartboard that allows the students to see the presenter – your classroom smartboard is perfect for this.
Adequate sound volume (usually from your smartboard or external speakers). Laptop speakers are inadequate for your whole classroom to hear the presenter
The above materials

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.

After the excursion individual collections can be brought together once students are back at school to start creating your own class herbarium! See what you can discover about the seaweed species near your school!
