Carbohydrate Lab

Question: what carbohydrates are in certain products?

Procedure: Have any product you want to use and test it but first test if monocacoride polycacoride and dicacoride has Benedict and iodine. Have Benedict, Iodine, Test tubes, and a dropper to first have your products for example a Tic-Tac, Tootsie roll, and a hot cheeto put all 3 things and put it in a separate test tube and grab your dropper and get benidict and pour it into the test tubes after that put the test tubes in a water bath and leave the tubes in there for a few minutes and if it changes color it has benidict. For iodine have the same products and pour iodine in it and if it changes color there is iodine in it.

Claims: Everything has a type of carbohydrate in it.

Evidence:
The picture of the tubes with blue liquid is Benedict and the tubes and it is in a water bath to heat up the Benedict causing it to react and change color, but it only changes if the product has Benedict in it with the red liquid is Iodine and it only changes color when the product has Iodine in it.



Research:

Reflection: If you are eating something right now you might be eating something with benedict or iodine in it or it can be both.

Water lab

Question: What is adhesion and cohesion and why is water sticky?

Procedure: have a penny, water, and a water dropper, drop as much water as you can on the penny until the water over flows. Then for the next experiment have two beakers and a string dip the string in water and grab the beaker filled with water and put one end of the string into the string and same with the other beaker and try to pour all the water into the other beaker by trying to pour it on the string with out spilling anything and the same amount of water should be in the other beaker.

Claims: Water is very sticky 

Evidence: The picture with the pennies is of water droplets stacking on each other.

 The bottom three pictures are of the transferring water from a beaker through a string to another beaker.


Research: (I got this information from http://water.usgs.gov/edu/adhesion.html) The reason why water is so sticky is because of Adhesion and Cohesion. Adhesion is water attracted to substances and                      
Cohesion is water attracted to water. Oxygen and hydrogen are attracted to each other causing water to be in clumps when it is dropped on things.
Reflection: I didn't know water could just flow onto a string and not fall out.

Ph Lab

Question: Tums vs Equate Which Is Better

Procedure:  Grab some Tums with different strengths or type and some Equate with different strengths or type, then have a Ph strips (a tester for Ph) and vinegar smash a Tums and a Equate poor the vinegar into a beaker put the Tums in one beaker stir it and test it with the Ph strips and repeat this with Equate.

Claims: Tums has the highest Ph so the Tums is more basic

Evidence:
Research: The Ph scale shows what is acidic and basic the higher the number the more basic it is and the lower the number the more acidic it is.

Reflection: I was thinking that the name brand would be more neutral but it turned out to be more basic than Equate.

Corn Lab

Question:  If you were to add bugs to your corn then will it cause the corn to grow better?

Procedure: I did all this in http://www.mhhe.com/biosci/genbio/virtual_labs/BL_01/BL_01.html what you do is grab the put it in the ECB infestation press Grow then repeat this two more times and this time add in low and then high bug infestation then you would weigh it and compare it to the other corn and compare how the bugs effected the corn then weigh one corn then the other and then add them up and divide it by three and you will get your average and the average will tell you wether or not bugs help it grow better or not. Bt is a bacterium soil that is found worldwide and it creates crystalline proteins that is stomach poisons for some insects so they inject it into the corn to kill off the bugs so they won't destroy the corn.

Claims: Corn with infestation helps corn grow better.

Evidence:






Research:

Reflection:  My thoughts on this experiment were wrong because I thought having a higher infestation will make the corn better but as you can see from my research and evidence my claim was wrong.
