Hi I’m new to Science Olympiad, and I was just wondering if anyone participated in Science Olympiad before, please tell me all about it! I’ve already read the rule book manual and schedules, but I feel like there’s not enough information—for example, the highlighted blocks as listed below are the ones I’m choosing to participate in this year, but what exactly are we studying in there? In Block A, what do we study for in Rocks and Minerals? Do we identify rocks? Tell me everything about it, especially the block events and try-outs please! And for the try-out test, I would like to know what that’s mainly about as well :) Thanks!

Explanation:

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
