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.
This week and a few before we have worked on solar cars. A solar car is a solar panel attach to a motor on a base. we got to decorate it as well. how it works is the solar panel is attached to two wires that you have to clip on to the wires that are on the motor. when it sees/hits sunlight it will move. If you didn’t space the wood and stuff properly it will not go.
Who discovered solar panels?
When did solar panels become a thing?
Where were the made/founded?
Hi this is my first blog of this year!! This week was….. LOC! This year we spent two nights and this year I did the high ropes course. while I was doing the ropes course I was so so so scared. the post felt like the where swaying, you had to clip yourself in to like change it and it looked a bit old and rickety. I did have fun. I did cry. and I do want to go back! We played a game called protect the fort and you had to go through training and the protect the fort. No one person was the leader. Everybody was included and I hope every body had fun!
When was LOC made?.
Who made LOC?
Are the consolers names real?
This year was the…BEST YEAR EVER! In science at least ;). My favorite lab we did was figuring out who wrote the “sporking cat” note. What I liked about it was how you could see the colored ink move from the reaction. My least favorite lab was… none I liked them all! The most interesting topic was the ocean and how it is suffering, not that suffering is fun or anything but what is really happening in the word. It was really interesting to watch some videos on the ocean to get a better under standing. I also really liked the biomes. I liked to learn about different places and biomes to know that there is more then just city a country. there is a whole other world like the dessert, rainforest and a whole ocean!
I wish we spent more time on owl pellets just because there is still a lot I don’t know about owl pellets. How do they form? How long do they take to form? What is an owl pellet? Is an owl the only bird that has pellets? I also wish we spent more time on plankton! We did spend a lot of time on it but I thought it was so fascinating! I thought it was so cool how you can’t even see them but then how do they eat? I also wished we spent more time on elements but we also spent a lot of time on them this year. I wish we learn a lot more then 11 elements but 11 is a lot. I wish we learned about animals and there origins, that sounds crazy but cool! Science helped me out with learning what is pretty on the out side is ugly on the out side. Like invasive species. Look Out!
I HOPED YOU ENJOYED ALL MY BLOGS!
SEE YOU NEXT YEAR!
