This week we had to research a diesese or genetic condition. I picked color blindness to research.
Color blindness is a genetic condition caused by a difference in how one or more of the light-sensitive cells found in the retina, (light sensitive tissue) of the eye respond to certain colors. These cells, called cones, sense the waves in light and enable the retina to see different colors.
The symptoms for color blindness are, difficulty distinguishing different color, such as ,red and greens, blues and browns, light green and yellow, blue and grey, ect. Others symptoms include difficulty distinguishing different shades of colors.
Here are some
-Color blindness is much more common for men.
-It is estimated that there are 300 million people in the world that are color blind.
– Babies are born color blind, but when they’re 6 months old they are fully able to see colors.
Why is it the it is more common for men to be color blind?
How do you get tested for color blindness?
Where was the first case of color blindness discovered?
My topic is the hypsometer. A hypsometer is a measuring instrument that uses angles and trigonometry (the branch of mathematics with relations to angles and sides of triangles and relevant functions). The term hypsometer comes from the Greek meaning “altitude meter”. There are three types of hypsometers: scale, pressure, and laser. These devices are mainly used in construction industries and by arborists to measure trees. The hypsometer was invented in 1846 by a forester named Martin Faustmann. He made his hypsometer out of a wood base, three rulers, string, a washer, and a mirror.
I made my own hypsometer. What I used was a protractor, string, washer, straw, and tape and this is how it worked. It is basically a plumb line hanging from a protractor. You have to look through a straw that is mounted on top and look at the top of the object you’re trying to get the height of, then you have to mark where the plumb line falls on a piece of paper, that would be your angle/tangent. If you were measuring a tree and you were ten feet away from the tree your adjacent would be ten. I used a trigonometry table to find my tangent. If your angle was thirty degrees then your tangent would be 0.577. I used a calculator and multiplied my adjacent (how far away you are from said object) by the tangent and that’s how the hypsometer works.
Is it more acturate to be farther away from the object and get the angel?
How actuate is a one you can buy?
does a half an angel affect the whole thing?
This week we had a party! A virus party. We all had test tubes and pipettes and liquids. We danced, Swapped liquids, Repeat. We did this 4 times. At the end we put this chemical that made it turn pink. one of them turn hot pink.
Last week we cut opens fruits and vegetables. It was really fun because we got to eat everything. the potato was starchy. The cucumber was slimey. I learned a lot like the function of an apple. well my guess is reproduction the clue it gives the amount of seeds.
