On the 31st of October Moonee Ponds Primary School went to GTAC. GTAC is a program that includes problem solving from a crime, learning about microscopes and more. We were introduced to a lady called Jacinta and a Lady called Nicole. Nicole and Jacinta explained all about what we were going to be doing while we were at GTAC. I was placed in a group with Amelia, Rebecca, Astride, Jessie and myself Kaitlin. Our group leader was called Sen and he is a scientist and study’s biochemistry, which is like alsimosers.

I learnt all about microscopes and there were two I found really interesting they were called: compound microscopes and stereo microscopes. Compound microscopes are used for helping you see a thin item and small details. The stereo microscope is used for seeing things close up like a leaf, if you wanted to see the small details and patterns you use a stereo microscope.
We had to solve a problem that included evidence that had been collected. The evidence that was collected from the suspect was a dung beetle behind the ear of the suspect, drenched fur, leaf around neck, seeds in the suspect’s fur, and feathers in fur beard. We didn’t get to finish the problem as we had limited time to get everything else done.
After, our group had some evidence. The evidence we had been given was a leaf, dung beetle, seeds, feathers. We had a chance to put the evidence under the stereo microscope, and we got to see the really detailed patterns. The dung beetle was really interesting to explore. I got to see inside of the dung beetles head and it was gross but interesting. All of the patterns that were on the feather were amazing. Even the bits of were the feathers are coming out you could see and it’s literally impossible to see with your eye. The seeds were really interesting as well because they had fur and patterns that I had never seen before.
Also, we had dirty water as some evidence. Our group had to get into pairs and get a piece of glass to put our sample water on. Then we put an ultra-thin piece of glass on top. When we had done that we put it under a compound microscope and we saw all kinds of germs, bacteria’s alive moving around.
Facts: Compound microscopes are used for helping you see a thin item and small details. The stereo microscope is used for seeing things close up like a leaf, if you wanted to see the small details and patterns you use a stereo microscope. Using microscopes help you see and kind of detail or pattern.
Understandings: My understanding of microscopes is very good after having a whole day around them and learning about them. My first understanding of a microscope is that they are used to collect small patterns, detail, and evidence. My second understanding is that Spirogyra is commonly found in fresh water, also that euglena is found in fresh and salt water, Paramecium is only found in fresh water ponds.
Question: My question is that how many science jobs are there?
