Plant graft_Pai.

Problem.

The plant will be using the water to grow, but when you switch the plant, they will be same species because they will grow. 

Hypothesis.

Plant not will grow because they hold by modeling clay not hold by solid. So, the plant will die.                   

Equipment.

                                                                     1. Plant.
                                                                     2. Knife.
                                                                     3. Scissors.
                                                                     4.  clay.
                                                                     5. Rope.

Method.

1. Set the tool.
2. Pick plant.
3. Use  knife to cut the 2 plants.
4. Switch between two plants.
5. Use the Modeling clay for hold plants.
6. After using the rope to hold between modeling clay and plants.










Question.

1.  why do we use clay?
     Answer.  because it will be a link between one plant to another plant.

2.  why do we cut at the node?  what is the node?
   
 Answer.  because the plant will be grown.

3.  why do we use string to tie it?                                                                                                                    Answer.  because it will be lock between one plant to another plant.                                                                                                                                                                                                                     4.  any observations?                                                                                                                                       Answer.  the plant is grown but then is same species.

Chemistry_Ice-Cream (Pai).

  Equipment.

1. Milk
2. Ice.
3. Salt.
              4. Koko crunch.
           5. Plastic box.  

Method.
1. Put ice to plastic box.
2. Put salt to ice in order to keep temperature steady.
3. Put milk to plastic bag.
4. Put the ice on one side of the plastic box and put the milk on the opposite side. another, spread the ice on top of milk.
5. Timming.
6. Let the  milk get set.
7. Put milk to cup and decorate.









Leaves structure and function____Bio.

Equipment
1.Leave - Monocotyledon.
                                                                           - Dicotyledon.
                                                             2. Microscope.
                                                             3. Water.
                                                             4. Glasses for microscope.



                                                                         Method.
                                                              1. Choose leave - Monocotyledon 
                                                                                        - Dicotyledon.
                                                              2. Knife to cut root,leave, twig.
                                                              3. Put on glasses and drop water.
                                                              4. Put on Microscope.
                                                              5. Wait for result.

Calorimetry 10 November 2016



Method.

1. Use the chip corn to put on weighing mach                                                                           
2. kindle on Alkahol.
3 drop water in test tube and touch on tool for hold test tube.
4. kindle for burn chip corn and control to test tube.
5. Wating to see the result.










Question and answer
1.The reaction is exothermic because heat final is greater than heat initial in the system.
2. chip corn is has gas to burn for water, water will be has oxygen and gas will has carbon dioxide.
3. water is led to secrete from chip corn burn.
4. only small percent of heat released is actually absorbed by the water in the test tube as shown by the huge percentage error.


Conclusion. 
  The chip will be led fire to burn for water on test tube. which the react water secrete oxygen and chip has carbon dioxide.

Reaction (Lab.....Time)



Question and answer.

1.  Is there a difference in reaction time between using your fingers and your arms to catch the ruler?

- Yes, it is different because the reaction of finger doesn't has many area to touch the ruler  and arm has many are arm. which, arm has chance 50% to touch more than finger.


2)  What do you think would happen to the reaction time, if you said the word monkey and then, dropped the ruler?

- The happened, dependent your brain not control the ruler, there will focus monkey.


3)  what would be the difference in reaction time, if the person was saying the alphabet and you dropped the ruler?

- We will focus alphabet more than focus ruler, which the reaction in every time has chance the ruler drop. 


4.  What is the different sensitivities of the forefinger, arm, and nape of neck?  
- The forefinger has the most sensitive more than arm and nape because sensory neuron in forefinger.
