testing for simple sugars

this week in science we done a experiment to test for simple sugars

aim:to test for simple sugars

equiptment: bunsen burner, test tube tongs, benedict's solution, a food sample

Method: put about 2 ml of the food sample then add around 5 drops of benedict's solutions then place over the flame (do not boil).

Results:a positive test for a simple sugar benedicts should result i a colour change from blue to orange

concusion: it is just easyer to just read the label on the back

how i used a 3d printer for the first time

the first thing i did was make a 3d model on tinker cad which is a 3d modelling website once i had done that i downloaded on to the computer that was connected to the 3d printer then i open the 3d printing software and got the printer all sorted and started printing it took 40 minutes

here is a picture of what happens when it go's wrong when trying to remove it from the base and it removes the bottom of the print and to much comes off

this is when you have just taken the back off

    once i had got the back off i sanded it down 

it was at its final stage

 

the changes i made was the colour of the 3d print and the size i made bigger because it was smaller than i wanted it to be and to bendy

writing (warning descriptive)

warning very descriptive










 There was a note in my fortune cookie that said, "Leave now don't say anything to anyone and never come back!. these cookies are uncooked and will give you food poisoning enjoy” i did not believe this was true  but the next day i was sitting down vomiting and filling the toilet with runny slimy feces i was sitting for 3 days filling the toilet and bucket about six times a day. The 10 litre bucket had turned yellow a did not help me stop vomiting it just made it worse the smell. I went through 5 cans of air freshener a day and that barely masked the smell it seemed like it would never go away. Once i was better i thought about cleaning the toilet instead i just replaced it and incinerated it in to ash using magnesium rods and 6 kilograms of thermite . but the bucket that was a whole different story i left it to itihsa to fix since she only had 3 braincells she thought it would be a good hat she put her head in it and licked clean she is still doing it today she only has 1 braincell left and there is almost not bucket left

disection of cow eye (warning graphic content)

Aim: to find out the structure of a eye ball
Methot: first we cut off the fat and meat off the out side of the eye 2. then we stabed the scalply in to the cornea that turned blue because it was dead the cornea is to protect your eye  3. we squeased the liquid in the cow eye. 4. then we opened the whole in the eye with sizzors to remove the pupil 5. then the lens that looked like hair gel it was a gelitene like subjets its purpose is to focus the light in to a image 6. then we cut it in half and looked at the retina with is senseitive to light .
results:

 

 

  
what eye learnt: 1. that fish have very smelly eye balls
the different parts of the eye. that there is a liquid in the eye the liquid is called the vitreous humor its purpose is to keep the retina in place
would you disect a cow eye

Waves and energy

telephone cups
aim: find out how well it can get a message from point a to point b
equipment: styrofoam cup x2, fishing line or any string, sissors
method: put two small holes in the bottom of the cups
2.cut a picece of fishing line to your desired length
3.put one end through a hole in the cup and tie a knot big enough that it wont go through the hole
4. do step 3 again on the other end
5. put the string tight and talk in to it on one end then and have someone listen on the other end and try tell them something and see if they can get it correct
