Earth and Environmental Science – Week 9

The end of the course is just one week away, and the UNSW Earth and Environmental Science students are finalising their investigation of Sydney soil lead pollution. Three weeks ago they sampled soils from around Sydney, two weeks ago they analysed them using x-ray fluorescence analysis, and last week they decided on some hypotheses, and collected the necessary data to test them.

Earth and Environmental Science – week 8

It is week 8 in the UNSW Earth and Environmental Science course, and the class is working towards writing a lab report on Sydney soil lead pollution. Last week, students used a portable x-ray fluorescence analyser to test soil samples that they had collected from their homes or across UNSW campus. This week the focus of the class was hypothesis testing.

Earth and Environmental Science – week 7

After a mid trimester break, the UNSW Earth and Environmental Science class is back. To finish the term, we are investigating Sydney's soil lead pollution. X-ray fluorescence analysis being explained Each of the one hundred students is invited to bring a soil sample from home. For those living in campus or in apartments, they get to sample soils on campus.

Earth and Environmental Science week 4 – groundwater

This week was groundwater week, and Sydney turned on the fine weather. The UNSW students had previously investigated the local geology and the soil hydrology. Now to tie it all together with an investigation of the local aquifer and groundwater hydrology. Sydney's Centennial Parklands is a wonderful place to do this.

Earth and Environmental Science – week 3

It is week 3 already, and this week one hundred Earth and Environmental Science students learnt about hydrology. Soil hydrology in the lab The group got to explore the Australian Water Outlook model and to determine the near surface soil moisture that was forecast from the model. They then went out on campus to measure the actual soil moisture and learn about sampling strategies and hypothesis testing.

Earth and Environmental Science week 2

It is week 2 of term at UNSW Sydney. This week, one hundred first year Earth and Environmental Science class had an Earth and Environmental campus tour. They got to understand the geology of the Sydney campus, and how the geology allows groundwater replenishment. This is important for the university to be able to have a stormwater harvesting system which then allows sustainable groundwater extraction.

Bags of soil are starting to arrive in the lab

This time last year our UNSW first year Earth and Environmental Science students collected soil samples from their homes for analysis for their lead (Pb) concentration. The resulting database was analysed to understand what determines soil lead concentrations in the Sydney region.

The term starts again here in just over a week, and we are running the project again. This time we have invited staff in the School of Biological, Earth and Environmental Sciences to bring in samples from home for our free soil testing sevice. The trolley is starting to fill up.

More on this and some results at the end of term. #science #soilscience #urbanpollution #unsw #environmentalscience #lead #GEOS1211

A photo from today's UNSW Earth and Environmental Sciences class. 100+ students brought in 100+ soil samples for analysis for lead concentration. Thanks to the speed and ease of use of portable x-ray fluorescence analysers, 100+ samples is no problem.

Next week the students will develop hypotheses and start to analyse the data, before writing a report on Sydney soil lead concentrations.

Historically, lead in city soil comes from traffic pollution, lead paint and lead solder, and this persists in the environment today.

Some samples had high lead concentrations, we will retest those and offer advice.

Teaching and educating can be fun and rewarding, and today it was my favourite class of the year.

#UNSW #GEOS1211 Earth and Environmental Science students took part in 'The Sandstone City' field class. An exploration of the Triassic Hawkesbury Sandstone, how it formed, and why it makes such a great building and decorative stone.

Thanks to my fellow educators Dr Indrani Mukherjee and Di Li Qian.

It was groundwater week with the UNSW Earth and Environmental Sciences team. The GEOS1211 explorers investigated ground water recharge processes, spring discharge and groundwater contamination. And there was time for a labyrinth too....
