Tums lab

Goals: The goal of this lab was to find out if the generic brand tums was better or worse than brand name tums.

Step 1: grind up the tablets generic and brand name of tums
Step 2: get 25ml of vinegar and poor it into a cup
Step 3: pour the powder tums into the vinegar
Step 4: use a ph paper and put it in the vinegar
Step 5: record the data

Data: this data shows the tums the purple is generic and the name brand is green

Claim: With The lab we did we found out that the name brand tums was better than the generic brands and that generic brand is the purple would be less effected as the the name brand tum


Reflection: the thing that i would of changed in the lab was that how many more trials i would of done

carbohydrate I.D lab

Question: What kinds of carbohydrates are food we eat

Procedure: milk powder, coffee creamer, gold metal,flour maltose 1220 ice cream cone garlic crackers and we just added water in all of those and put iodine in one and benedict in the one


Test 1: Benedicts
        1. Add your sample into a test tube
        2. add Benedicts solution
        3. Heat in a hot water bath


Test 2 : Iodine
        1. add your sample to a test tube
        2. add iodine














                                        Carbohydrate Identification Lab Analysis Questions

Use your results from the carbohydrates identification lab and any notes or resources about carbohydrate to answer the following questions:

 1. Name the three categories of carbohydrates studied in this investigation
Polysaccharide disaccharide and a monosaccharide

2. What three chemical elements are present in all carbohydrates
Carbon Hydrogen and oxygen

3. Give two examples each of the names of sugar molecules from our discussion or the textbook/online that are:

A: monosaccharides - glucose,fructose
B: Disacharides-sucose,jactose
C:polysaccharides-starch,glycogen

2: How many times larger is the number of hydrogen atoms than oxygen atoms:
 
     a: water hydrogen-2   oxygen-1
     b: carbohydrates?  2 times

3 "Mono means one, "di" means two, and "poly" means many. why are these terms used in describing the three types of sugars?

It means how many sugars are in it

6. How can you tell by using Benedicts and iodine solutions if a sugar is a
                     
          A: monosaccharide? Iodine-nothing benedict- turned green
          B: Disaccharide ? Iodine-nothing benedict-same
          C: Polysaccharide Iodine-black benedict-nothing

7. A certain sugar has no change in color when tested with benedicts solution
     
         A. Can you tell what type of saccharide it is?- disaccharide and polysaccharide
         B. Explain. Because our evidence shows that on our graphy poly reacts to iodine and di reacts   to neither

8. A certain sugar has a color change in Benedict's solution
     
         A. Can you tell what type of saccharide it is? yes
         B. Explain. It is a monosaccharide because it turned yellow-green in the benedict

9. Give a examples of foods that contain
   
         A. Monosaccharides-milk powder
         B. Disaccharides-coffee creamer
         C. Polysaccharides-gold medal flour

Claims: In this lab i thought that all of the colors would change colors when we have heated the liquids up and then add iodine i thought they would all stay the same but only had really changed a color

Reflection: nothing really changed colors in the lab but one tab and it went from light brown to darkish brown all of the other tabs stayed the same

Water Lab

Introduction:
 what has a stronger surface tension of cohesion bonds between water and alcohol

Step: 1 you want a pipette full of water
Step: 2 need a penny
Step: 3 you want to drop as much water droplets on the penny as much as possible
Step:4 you want to record the data of how many droplets of water you put on the water
Step:5 Try to put as much alcohol as you can on the penny without it falling off the penny
Step6: string stretch it as much as you can poor down water on it and see how much water can go into the cup by pouring the water on the string and see how much water the piece of string it carry alongside it

The graph below shows the amount of drops each penny was able to sustain and that it also shows that water has a better surface tension i have other data recored and it shows that water does have the better water tension than alcohol and the cohesion bonds in the water are greater 

Reflection: what i have learned is that water droplets on a penny does not cover as much as the alcohol droplets the penny is able to carry more alcohol droplets than water droplets 

Claim: i found out that alcohol will have more balance on the penny then the water will on the penny 

corn lab

Questions does genetically modified corn grow better than non genetically modified corn when its infected with bugs ?

Procedure

I went to this site and grew some corn that was infested with bugs and grew some corn with few bugs and grew corn with no bugs

 Step 1: You want to pick the corn you first want to experiment with
 Step 2: You then decide if you want plain corn to grow or the corn to grow while being infested with a small amount of bugs or a large amount of bugs
 Step 3: Push the grow button and write and record what is happening is the corn growing fast with or without the infestation of bugs or is it the same ?
 Step4: Then record the data and put it into a graph data and see which corn grew the fastest and which did not and how was the corn affected by the bugs if affected at all ?

http://www.mhhe.com/biosci/genbio/virtual_labs/BL_01/BL_01.html

This is the data i have collected while during the corn lab each level of ECB infestation is High some of the data increases than slightly decreases but increases within time the corn was logically not affected by the bugs to have a positive effect on the corn anyways when it was infected with large amounts there was little corn and didn't weigh much but when put with little bugs or no bugs the corn will have a positive growth and be like regular corn

Evidence 

Research: In my research the good corn was the corn that had few bugs and the super corn had lots of bugs the bt123 had lots of bugs and the bt456 had few bugs and you can see that the corn grew just fine with small bugs but with a larger amount its growth decreased

Claim In the graph above, it shows that BT 456 is the one that weighed the most out good corn super corn and BT123

Reflection: My hypothesis for this lab was correct i knew that having few bugs on the corn while it grows would not effect the growth of the corn
