CLEVER PERSON'S QUIZ
Question:
When is titanium both gold and tin?
The answer will be in the next edition of the Rowe Scientific newsletter.
Did you know the answer to the last quiz question?
Aside from being the national flower of Ukraine, for what other reason would sunflowers be planted around the Chernobyl Exclusion Zone?
Answer:
Phytoremediation.
This is the use of green plants to remove pollutants from the environment, or to rend them harmless. Multiple studies have shown that certain plants, including the common sunflower Helianthus annuus, are Hyperaccumulators, helping remove heavy metals from the soil and groundwater. Sunflowers in particular have been noted for their hyper accumulation of Lead, Uranium, Strontium and Cesium, and weaker levels of uptake of Chromium and Cadmium.

Investigating Hall Effect through toroid electromagnet
The Hall Effect results in the formation of a potential difference perpendicular to the current, when a magnetic field is applied. Jerry wanted to investigate whether the Hall Effect voltage could be predicted accurately as the applied field was changed by varying the current through the toroid. He found that the theoretical and experimental values matched well.

Effect of artificial light at night on spotted duckweed
Totoro was curious about the effect of artificial light upon the growth of duckweed so carried out an investigation. He discovered that whilst duckweed leaves grow quicker under artificial light, compared to a control group, they were more likely to perish, most likely due to the stress they were in.

Mr Declan Breen – Encouragement Award in Chemistry
How Nitrogen Pollution is Changing our Waters
"The nitrogen content in the atmosphere and oceans around the world is increasing as global warming continues causing harmful nitrogen pollution. This is predicted to continue to rise to catastrophic levels causing harmful algal blooms, eutrophication and causes dead zones, meaning there isn’t enough oxygen in the water to sustain life. The hypothesis that was formed was the greater the molarity of the nitric acid, the quicker the calcium carbonate would dissolve. To test this, calcium carbonate was placed into dilute nitric acid of molarities of 0.1, 0.5, 1 and 2, then once the calcium carbonate had fully dissolved the timer was stopped. Faster times meant that greater nitrogen content in water resulted in faster dissolving of calcium carbonate. This experiment was repeated 5 times per molarity of nitric acid and an average time for each molarity was calculated. After the experiment concluded it was found that higher molarities of nitrogen in water result in faster dissolving of calcium carbonate. This experiment shows what will happen if nitrogen content in oceans continue to rise due to our actions.."

Mr Akhil Talapaneni – Highly Commended in Chemistry
Effects of Acid Rain on Calcium Carbonate
"Global sulphur emissions are one of the leading causes to the rising acidity of rain. When sulphur is released into the air it dissolves in atmospheric water particles, forming a dilute sulphuric acid, or acid rain. When this dilute sulphuric acid comes in contact with calcium carbonate in nature, usually through the form of rain, it begins to corrode much faster. As more and more sulphur is released in the atmosphere the concentration of this chemical in the rain will continue to increase, making it more and more acidic over time. The purpose of this experiment was to determine the effect of the rising acidity of rain on calcium carbonate in nature. This was done by placing 0.10grams of calcium carbonate powder in different molar concentrations of sulphuric acid, a compound mimicking the properties of acid rain. The concentrations of sulphuric acid used in this experiment was 0.1, 0.5, 1 and 2 molar. The results of this investigation indicated that as the molar concentration of sulphuric acid increases, the dissolution time of the calcium carbonate powder decreases (0.1 molar acid - 7 minutes 33 seconds, 0.5 molar acid - 5 minutes 13 seconds, 1 molar acid - 3 minutes 49 seconds, 2 molar acid - 1 minute 9 seconds), supporting the hypothesis. This experiment may contribute to the environmental science field as the results show that the rising acidity of rain also increases the rate at which it destroys calcium carbonate based objects in nature, such as limestone, marble and coral."

Mr Kiran Myutel-Mansur – Encouragement Award in Biology
Which Source of Bacteria is Most Resistant to Hand Sanitizer?
"Hand sanitisers gained momentous popularity in recent years. They are extremely popular because of the availability of its contents and its bacteria killing efficiency. However, different bacteria have developed different levels of resistance to hand sanitisers. This experiment investigated many sources of bacteria and their resistance to hand sanitisers. The process required the collection of different sources of bacteria on cotton swabs, such as tabletop, hand surface, sweat, and saliva. The cotton swabs were then put into test tubes filled with one type of hand sanitiser for different lengths of time. The bacteria were then swabbed onto an agar plate, and left in a safe, untouched environment for a week. Colony-forming units formed on the agar plates were then recorded. If the results were credible, they show that not only are bacteria from multiple different sources resistant to this type of hand sanitiser, but they have the ability to thrive in it."

SCIENCE TEACHERS’ ASSOCIATION OF THE NORTHERN TERRITORY ROWE SCIENTIFIC PTY LTD 2022 PRIZES
Congratulations to the recipients of the prizes sponsored by Rowe Scientific Pty Ltd in the 2022 Young Scientist Awards, run by the Science Teachers’ Association of the NT. The following are two examples of the recipients.
|
|
|
Ms Jocelyn Mayger
"This experiment aims to investigate the relationship between the strength of an electromagnet and distance from a ferromagnetic object.
Electromagnets are comprised of a magnetic core and a coil through which electric current passes through and are used when the magnetic field is to be controlled (Britannica 2022). The application of this type of magnet can be seen in generators, transformers, and loudspeakers.
There are several factors that affect the strength of an electromagnet including the shape of the electromagnet, the number of coils, voltage, and distance. In different applications of these magnets, different factors are changed. Ferromagnetic objects are comprised of a material that when placed in an external magnetic field are strongly magnetized in the direction of the field (BJUS 2019). Naturally occurring ferromagnetic materials include lodestone and iron, which are also used in generators, transformers, and loudspeakers.
Through identifying the relationship between the magnetic force and distance, the relationship between the strength of an electromagnet and distance will be identified."

Ms Zafeera Jahana
"The results of the investigation on the catapult project are of poor quality as the aim of the investigation is not accurately fulfilled. Hooke’s Law states that for small deformations of an object, the displacement of the deformation is directly proportional to the deforming force and if the force is removed, the object returns to its original shape and size (Britannica, 2022).
Before the investigation, the spring constant was 38.9 Newtons per metre whereas after the investigation, the spring constant was 29.7 Newtons per metre. The spring constant decreased: the rubber band was deformed – stretched – by a large amount, which prevented it from returning to its original shape and size.
The rubber band was stretched during the investigation, when the spring constant was not measured, as it was assumed to remain uniform throughout the experiment, which means the trials were conducted with a rubber band with different spring constants. The independent variable is the variable that is purposely changed (Thought Co, 2022). In this investigation, the aim was to observe how the independent variable (I.V) - the number of degrees that the catapult arm is pulled back affected the distance travelled. However, the decreasing spring constant is an unintentional changing variable. While the I.V was changing, so was the spring constant. The distance travelled is facing both these changes, yet only being measured for the independent variable.
This is unfair and prevents the aim being fulfilled. As the spring constant of the rubber band changed during the investigation and the distance travelled did not take the changing into account, the accuracy of the results of the investigation was affected and thus the results are of poor quality as they do not accurately display how the number of degrees the catapult arm was pulled back affects the distance travelled."

Optical Glass Sorting Device
Mr Peter Cadman-Thompson, The Friends’ School
First Place, STEM Challenge, Division 5
"The aim of this STEM Challenge is to create a prototype which will differentiate between two different colours of glass. This will be done using my understanding of arduinos, 3D modelling and printing, construction, sensor technology, coding, troubleshooting, bug fixing, soldering and wiring.
All types of glass can be recycled, however clear glass is made up of silica, limestone, and soda ash, while coloured glass includes additives such as iron, sulphur and dyes. This means that different coloured glass can not always be recycled together. The project was chosen to assist with the process of recycling glass.
This machine will make the recycling of glass much more efficient and cost effective and will mean that less glass has to go to landfill. Recycling is far more sustainable than constantly making new glass. Sorting glass by colour is a crucial element of the recycling process and this device can help a recycling plant to automate colour sorting and take away the manual sorting process which is time and labour intensive.
The prototype was able to clearly identify at least two different colours and sort them accordingly for the vast majority of cases."

A Big Small Problem in the Mersey River (Microplastics Investigation)
Ms Aimee Smith, Ms Matilda Fidler, Ms Annabel Leary-Burke, Reece High School
First Place, Environmental Science Project, Division 5
"The aim of this project was to investigate the amount of microplastics in the Mersey River in the north of Tasmania. It was hypothesised that the amount of plastic would be higher closer to the harbour or other developed areas compared to more rural locations.
During the experiment, the results significantly differed depending on the population of the places, the area in which was examined, and the historical events which occurred within the locations. Each location examined within the experiment was found to have different physical characteristics which affected the samples taken, and the results that were found. Overall, it was found that more populated areas had a greater number of micro- and nano- plastics, as well as larger plastics."

Too Late for Tea Time – Bacterial Growth in Tea Samples
Ms Emily Schipp, Launceston Church Grammar School
First Place, Research Investigation, Division 5
"An investigation was conducted into the impacts of production and consumption on bacteria naturally grown in tea samples. This was done with the intention of divulging the effects of the oral microbiome on the morphology of bacterial colonies grown in four different tea varieties in relation to their oxidation levels where applicable.
Tea leaves are typically produced using one of three techniques depending on their type: leaves originating from the plant Camellia sinensis are oxidised, herbal tisanes are steeped, and lesser-known varieties such as pu-erh and kombucha are fermented.
This investigation intends to compare the number of bacterial colonies grown, as well as the qualitative characteristics of these colonies, in four different tea samples both before and after being inoculated by the oral microbiome. Several days after being partially ingested, a swab of each sample was spread on a nutrient agar plate so that colonies could form for observational purposes. The results reveal that the bacterial colony count in tea decreases and that the species of bacteria present change after consumption."

Mr Hamish Grant
“My name is Hamish Grant and I am entering my final year at the University of Sydney, studying a Bachelor of Science, majoring in Chemistry and Data Science.
I’m fascinated by the intersection between research and practicality where most chemistry resides. The theory of chemistry, when broken down into constituents, is logical while also having a wide range of practical uses. I like that theory can be put into practice on the same day when one has access to a lab.
I find physics and math very interesting but too reliant on other variables for application. This scholarship has enabled me to focus on my studies without the threat of my living situation crumbling and I am truly thankful for your generosity.”

WESTERN AUSTRALIA
Dear Clients.
We are (almost) over the annual price increases, and unlike last year, do not expect to receive “mid-term” corrections. Hopefully the supply chain steadies, though freight is still a significant proportion of the cost of goods.
As with most companies, we have been looking for new staff to fill vacancies through both movement and new hires. The market seems to be easing and we have added some fantastic talent to the team.
In manufacturing this month we welcome Kathy and Rozarna, to internal Account Management, Kim Charlton (returning to Rowe Scientfic Pty Ltd after “external training”) and in external Account Management, soon to join, Ayman Fawzi to call on our Kal clients. As always, we appreciate your support every day, and please look to us when in need.
All the best from:
Peter Sommers and the Western Australian Team.
