- Have a look at the new page called "Ask a Science Question".
- Do you like the new layout for Mr A's Science Blog---your comments please!
- Don't forget the Question of the week, at the moment Felix is in the lead!
- Year 7 Physics have a Web Quest Project---check out the page for details.
Mr A
I love the new layout, Mr Alan :) It's an improvement from the earlier one, because it's brighter and easier to read!
ReplyDeleteI think you a mistake - You said that Felix is in the lead, but it says that he has 8 points, and Ritish has 10. I think you forgot to update Felix's points? Just pointing it out :)
Thank me Felix :D
1. What is a paleoanthropologist?
ReplyDeleteA paleoanthropologist is someone who studies human fossils.
2.They analyzed what sort of bones from two early hominid relatives of humans?
The central wrist bone.
3. What are the names of the two ancient human relatives they studied and how long ago did they live?
Australopithecus anamensis and Australopithecus afarensis (the "Lucy" fossil). Australopithecus anamensis is 600,000 years older than Australopithecus afarensis.
4. Why did they study these sorts of bones?
To see how these bones differ between arboreal animals (animals that live in trees) and more terrestrial ones (animals that live on land).
5.What did their findings show and what reasons did Macho give for these results?
the fossilized wrist bones suggested that humans switched from trees to living on land between 4.2 and 3.5 million years ago.
Macho said this was because the wrist bones of the tree dwellers experienced more stress on the pinky side, while the terrestrial dwellers experienced more stress on their thumb side.
Thank you, :)
Hope they are right, my source was a news article.
Thanks for the comments on the new layout Kim.
ReplyDeleteThe final points list is on the Question of the Week page---I think its fully updated.
Great answers! Felix got them all except the last one, so you get 2 points for that one!
Mr A
Mr A, The new layout is very nice :)
ReplyDeleteAre you going to be putting information on the new Web Quest?
Just Asking,
Thank You :D
D.R
I like the new layout it is very nice and I am thinking about a question. Just quickly my dad was telling me thought you would be interested did you know that in the lab when doctors are researching cancer cell they play tic tac toe and other board games using the cells as counters. Just thought I would share
ReplyDeleteAlso one of the sites mentions foreseeing a wind storm in the USA sound interesting and I will try and answer next week's questions Kim beat me to it this time
ReplyDeleteThanks Danya.
ReplyDeleteThe info about your Web Quest is on the Year 7 page.
Mr A
Nayonica, I didn't know that about tic tac toe!
ReplyDeleteMr A
1)Only the top surface of the cat's tongue touched the liquid.
ReplyDelete2)Gravity.
3)Inertia is the tendency of an object to continue doing what it is, i.e. if it is at rest, it will remain at rest, or the same if it is in uniform motion. The cats use this force in order to overcome/balance gravity so the liquid continues its motion and comes straight into the cat's mouth when it whips its tongue back creating a column of the liquid.
4)The surface of the liquid.
5)The scientists tested their theory by first capturing cat's drinking with high-speed cameras and then slowing the video down to calculate the frequency and speed of the laps. They then tested this on other cats.
6)The lapping speed of bigger cats will be slower as they have larger tongues and must thus balance gravity and inertia to drink properly by slowing down.
My source:-http://web.mit.edu/newsoffice/2010/cat-lapping-1112.html (check out the video on this site!)
Brilliant Ritish! That was certainly a quick response to the question and all answers were correct. It is the tip of the cat's tongue that does the important work of pulling a column of liquid, working against gravity, into the cat's mouth.
ReplyDeleteEveryone should check out the video Ritish mentioned or you can access it here at http://news.discovery.com/videos/animals-cats-drink-differently-than-dogs.html
Ritish gets 7 points!
Mr A
Now I get why you are not supposed to oversleep on a a Saturday Ritish is going to have the question answered before me and I have made a start on the web quest
ReplyDeleteExactly Nayonica!
ReplyDeleteGood, don't forget to use the web links on the Web Quest to research your two energy sources.
Mr A
I am working on the question
ReplyDeletethis is in the order I figured it out in
ReplyDeletethe asleep: I fall asleep
sk8 is : I skate on ice
uction: reduction
1 square 2: square root
what must: waht goes up must come down
correctio for the first one back to square one
ReplyDeleteHow Long should our reports on our energy resources be because both sites have the same information and I am not saying the thing that are not related so maximum how much oh and did you see my correction on back to square one hope all the other questions were right we all had fun with those questions at home
ReplyDeleteand also that video on the web quest site is really helpful
ReplyDeleteNayonica, you got two of these right but the others are not (but you are close).
ReplyDeleteMr A
Mr.Alan i liket he new layout! LL
ReplyDeleteThanks Lea.
ReplyDeleteMr A
Did you get my ther comments where I said that the sqare root is back to square one and how long should our reports for the webquest be
ReplyDeleteI didn't receive that Nayonica.
ReplyDeleteMr A
that explains it I changed the square root to back to square one
ReplyDeleteNayonica, post all correct 5 answers to this question again.
ReplyDeleteMr A
i put them in order
ReplyDeletethe asleep: I fall asleep
sk8 is : I skate on ice
uction: reduction
1 square 2: square root
what must: what goes up must come down
.... did any one answer them?
Ok how about this
ReplyDelete1. Back to square one.
2.Falling asleep
3.What goes up must come down
4.Skate on ice
5. Reduction
Not quite right Lea. Nayonica is also very close!
ReplyDeleteMr A
Did you get my new answers
ReplyDeleteNo I didn't Nayonica.
ReplyDeleteMr A
1 square 2: reverse order
ReplyDeletethe asleep: falling asleep
what must: what goes up must come down
sk8 is : skating on ice
uction: reduction
1 square 2: reverse order
ReplyDeletethe asleep: falling asleep

(the previous comment is mine too)
Kim, good try but two answers are wrong.

Paleoanthropology which combines the disciplines of paleontology and physical anthropology, is the study of ancient humans as found in fossil hominid evidence such as petrifacted bones and footprints.

ReplyDeletefor the 2 question in the poem caxton is a book
ReplyDeleteGood Nayonica---but you've posted here why? Post to the post where the poem is!
