Things like factories that send out greenhouse gasses and carbon dioxide into our atmosphere. Some other things like burning fossil fuels and cutting down trees are also causing climate change. Everyday things aswell, like using…

Biology lab – the cell cycle and mitosis
Early Prophase: the DNA in the nucleus starts to form chromosomes. Late Prophase: The nucleus then breaks and disappears and forms two stringy spindle poles that move to opposite sides of the cell. now the chromosomes are in the middle of the cell without a nucleus. The spindle fibers start to reach out for the chromosomes. Metaphase: The chromosomes line…
Edible DNA
Alexis Aragon My model: 1.This model shows that DNA looks like a double helix ladder. DNA reproduces and can be interchanged because the combinations (T and A, and G and C) are almost unlimited. It shows that DNA can be different for everyone and holds genetic information with the different “ladder steps” and order. This model of DNA shows how…
Currents in the Kitchen

Materials: 1 voltmeter, 2 wires, 1 nail, 1 copper strip and at least 3 fruits/vegetables. (More if needed) Procedure: Grab your fruits or veggies. Stick in your nail and copper strip…
OIl Fracking in BC
What questions did you need to research in order to create your sway? The questions we researched about oil fracking were: What is oil fracking, how is oil fracking bad for the environment, what do we need hydraulic fracturing for, is there alternatives for oil fracking, hydraulic fracturing in BC and, how does oil fracking produce energy. What new or…
Periodic Table Reflection
Alexis Aragon What do I know well about the periodic table? I know that in the periodic table, the elements are organized by atomic number and atomic mass. I also know how to find the number of neutrons in an atom very well now. I know about Ions, and how an atom becomes an ion. I also know about valence…
Fictional Safety Story
Alexis. A It was the last block of the day and me and my friend Fiona are in science class. Everyone was so excited about the science lab tomorrow and can’t wait. But first, we had to get through this science class which is all regarding an ethical dilemma. Our ethical dilemma that we were talking about was animal testing/experimenting.…
