This semester in Science 9, I learned many new things about the Periodic Table, circuits and electricity, cells and the reproduction cycles, and climate change.
Safety
During the start of Science 9, we learned about the health and warning symbols on daily and household products that we should be aware of, such as the corrosive sign, the health hazard sign, the compressed gas symbol, and the flammable symbol. Each symbol or sign has its own meaning of what it means and what it does so you can protect yourself and others around you.
For example, the compressed gas sign means that whatever is being compressed is a gas and can exploded out the material if not cautious with the product.
Chemistry
During our chemistry unit this year, we learned about the periodic table and their groups, families, and features. I also got to familiarise myself with the table and how it was arranged, some other compounds that weren’t on the periodic table, polyatomic ions, element features, and their chemical reactions to other substances.
For our final chemistry project, we had to choose an element and do some research on it as well. For example, the element that I chose to research was platinum which is made to make records with.
Physics
Throughout our physics unit, we learned about Ohms Law along with voltage, current, and resistance. We also learned how to read resistors with their different coloured bands, how to read a voltmeter and an ammeter with one, five, and ten volts for a voltmeter or amps for an ammeter.
For our lab, we did the Currents of the Kitchen Lab where we had to make a circuit with fruits from our home.
My group and I used half a lemon, half a potato and a whole banana. We then had to try and make an LED light turn on with only using the food that we had. We made series and parallel circuits and we learned how electricity moves through different objects.
Biology
Our Biology unit was full of new things that needed to be learned, such as mitosis, meiosis, the cell cycle, cell division, and reproduction. We learned all of this with the help of our may learning experiences along labs, worksheets, and group projects.
Here are some pictures of the projects we did during our biology unit of Science 9 with Mr. Robinson.
Climate Change
With climate change, we’ve learned about the carbon in our air, the four spheres to our Earth, biotic and abiotic factors, and what we can do to help make a change.
We also made our own innovation to help solve climate change called the Carbon Compressor and Collector in Minecraft with the help of Elandi and Emily.
Skype With Catherine
With Catherine, we learned how most girls can’t go to school because of pregnancies or because of the commute to the school itself.
That can be hard on them, especially without water or it being so far away to reach. Climate change is even a bigger factor in Uganda because of it’s rising heat temperatures nowadays.
Here is a picture of all the questions we asked Catherine:
