Daddy and I took the Internet "could you pass 8th grade science test" test.
We got B+ (by getting 23 correct answers out of 26 questions).
This is pretty good for a seven-year-old stuffed elephant, and pretty poor for a Cambridge graduate. Isn't it Daddy!
Daddy got questions 2, 4, and 9 wrong. (And I got ALL of the other questions RIGHT!)
Q2 "This type of rock is buried deep within the earth's crust"
Daddy answered "Igneous", but the actual answer was "Metamorphic"
Igneous rock is made when molten lava cools, either on the surface after erupting from a volcano or deep underground. 95% of the Earth's crust is made up of igneous rocks, but generally covered with a thin layer of sedimentary and metamorphic rocks.
Sedimentary rocks are formed from layers of sand or mud or dust laid down over hundreds and thousands of years and squashed together
Metamorphic rocks are rocks that used to be igneous or sedimentary but have been transformed by huge heat and pressure at great depths in the Earth's crusts. Shifts in the Earth's crust and erosion then lead to metamorphic rocks turning up on the surface.
So TECHNICALLY Daddy is right, since both igneous and metamorphic fit the description in the question; the question should have been less ambiguous by saying that this rock is ONLY MADE deep within the Earth's crust.
Q4 "Which form of solar radiation causes sunburn?"
Daddy answered "Infrared" but the answer was "Ultraviolet"
This is called being too clever for your own good – Daddy knew that (a) infrared radiation carries heat and (b) ultraviolet causes skin cancer and thought is was a double-bluff. More fool daddy!
Q9 "What is the name given to water loss to the atmosphere by green plants?"
Daddy answered "Evaporation" but the answer is "Transpiration".
Well, transpiration, according to the wikipedia is "…the EVAPORATION of excess water from aerial parts and of plants…" which leaves Daddy feeling slightly better since at least the process is a specific example of the one that he identified.
Actually, Daddy thought that "transpiration" referred to the entire process where water that was absorbed in the plants roots is drawn up the stem to the leaves. (Evaporation of the water at the top causes a reduced pressure at the top end of the plants internal tubes and sucks the water up. Just like a straw.) Which is why he picked "evaporation" for the actual water evaporating part of the process.
I think that Daddy deservers an A-
That is he gets two extra marks for the AMBIGUOUS questions 2 and 9 but LOSES a mark for being a SMARTY-PANTS about it!
PSMy diaries DO seem to have been all SCRAMBLED recently but we are back up to date again now!
PPSIn reply to Mr Niles' comment... Daddy is OKAY at maths.
|You Passed 8th Grade Math|
Congratulations, you got 10/10 correct!
