toxic lab

poison: The poison i will be talking about is hemlock or known as conium it is a highly toxic flowering plant

Location: Found generally in Europe 

Usage: 100mg of conium or about 8 leaves of the plant is fatal 

Symptoms: Death will come in paralysis your mind is wide awake during the process but your body doesn't not respond to what is happening eventually your respiratory will start to shut down 

Burning this plant can make it difficult to breath and people with asthma should be very cautious of this plant 

Treatment: The only treatment is to be rushed to the hospital for it will first attack the respiratory system and odds are you won't know how to treat that nor have the equipment so the only known treatment is to be rushed to a hospital

Dry Lab

Procedure:
1. we cut out 10 circle liked spinach leaves
2.Then we filled the syringes half way with baking soda
3.Then oxygen was sucked out of the leaves and we waited for them to sink
4.Finally we put them in front of the light and waited for them to float up

Research:
Photosynthesis is a procedure used by plants and other organisms to covert the light energy it gets and into chemical energy that can later be released to fuel the organism. in the lab i saw photosynthesis accrue  during the lab when we have put the leafs in front of the light the spinach leafs had floated to the top of the syringe because of photosynthesis because when the light hit the syringe the leaf would react to the heat produced from the light and rise up but it did take a while for it to rise

Materials
1. syringe
2.spinach leaf
3 Baking soda
4. Red and Blue plastic cup
5. bright light
6. hole puncher or material that can make circled leafs

Graph:

When we put the leafs in the syringe surrounded by the red film and put it in front of the light photosynthesis occurred faster than baking soda and the blue film we originally thought adding a lot of baking soda would increase the thought of photosynthesis but it ended up being the 2nd best at photosynthesis and the reason the blue film was the lowest was because the film its self is darker and it is harder for the light to penetrate thought the dark blue film and its a lot easier for it to go through the red film

Reflection: The thing i would do differently is add a more intense light to see an increase in time for photosynthesis to happen it took around almost ten minutes for the first leaf to rise up next time i attempt this lab i am aiming for a shorter time and faster rise of leafs

Photosynthesis Dry Lab

In this “dry lab” you will be working backwards from what you would normally do in a lab situation. In this case, you will be given a set of observations that were made in a lab and you will be asked to reconstruct the procedure that could have generated this data. You will also be given a set of facts that you will use to explain this set of observations in the analysis and conclusions section of your lab write-up. As you create the procedure for this lab, please remember all the rules that you have been learning about good experimental design.

Your lab report begins below. Fill in the missing sections of the lab report using the observations and facts given. You may assume that you have access to as many test tubes, snails, Elodea plants, light sources, dark places, and as much pond water and BTB as you need.

My Most Awesomest Photosynthesis Lab Report

by

Question(s):

Background Research Facts About Photosynthesis and Respiration:

• Carbon dioxide in water produces carbonic acid.
• Bromothymol Blue (BTB) is a blue-green liquid which changes to a yellow color in acid and back to blue-green when returned to a neutral pH.
• Carbon dioxide plus water yields sugar and oxygen when chlorophyll and sunlight are present.
• Animals respire.
• Green plants photosynthesize in the light and respire all the time.
• Sugar plus oxygen yields carbon dioxide plus water and energy.

Materials:

1. water

2. blue Btb

3.beaker

4.snail

5.plant 

Procedure:

1. put room temperature in beaker
2. put four drops of btw in beaker with water 
3. stir the beaker till btb is mixed with the water
4. put a snail in beaker that has water and blue btw
5. then follow step 1,2,3 with a new beaker
6. put plant in the new beaker 

Results/Evidence:

1. Water plus bromothymol blue is blue-green.
2. Water plus bromothymol blue plus an aquarium snail turns yellow.
3. Water plus bromothymol blue plus Elodea (an aquarium plant) is blue-green in light.
4. Water plus bromothymol blue plus a snail plus Elodea is blue-green in light and yellow when left in the dark for three hours.

Analysis of Results (use your Research Facts to explain each result):

1. Water plus bromothymol blue is blue-green because... bromothymol (btb) is a blue looking liquid which later turns into a yellowish color in acid and back to blue- green when returned to a neutral ph

2. Water plus bromothymol blue plus an aquarium snail turns yellow because... when you put a snail in water then the acid of the snail and the carbon dioxide react with btb which changes to yellow

3. Water plus bromothymol blue plus Elodea (an aquarium plant) is blue-green in light because... when you put the plant elodea in some water it turns to blue-green

4. Water plus bromothymol blue plus a snail plus Elodea is blue-green in light and yellow when left in the dark for three hours...

Enzymes

Enzymes: A substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. Enzymes are protein molecules that are manufactured by all plant and animal cells. All Cells require Enzymes to survive and function. Enzymes are catalysts, which means that they make chemical reactions to go faster but are not changed by the reaction research has shown that people who have a chronic disease or have low energy levels also have lower enzyme content in their blood , urine, and tissues

Why Are enzymes important:
Enzymes are on of the most essential elements in our body enzymes are more important than the air you breathe the water you drink and the food you eat why is this ? Enzymes are required for your body to function properly because without enzymes you wouldn't be able to breath swallow drink eat or digest your food to do all of these things your body needs some help. you must have enzymes to help perform these tasks. Enzymes are an absolute necessity to live.

Procedure:
1. Fill a pan almost full of water
2. lay the 50 ml graduated cylinder on its side in the pan so that it fills with water completely
3. we put 10 ml of peroxide and 1 ml/ 2ml in a test tube
4. Then put a plug in the test tube
5. after that we placed it in the pan sideways
6. observed it for 10 min

Reflection:
Next time we should put more yeast to see if it bubbled faster or we could have put it in warm water instead of cold water, to see if there was a change in the time of the bubbles

Claim:
The more yeast you have the more bubbles you get

Question:
What circumstances did the enzymes react faster we tested it with 1 ml of yeast then we did it with 2ml and we could clearly see that the 2ml of yeast made it react faster

Pku

Intro: Phenylketonuria (pku) is an inherited disorder that, left untreated, changes in cells inside the brain and leads to mental retardation. This dramatic change in behavior can be traces to a tiny mutation in a single gene on chromosome 12.

How it is Inherited: PKU is not a contagious disease but an inherited disorder. Inheritanceof pku starts with the parents. Each parent has two PAH (phenylalanine hydroxlase) genes, one on each chromosome 12 one of their genes is mutated ( as represented by the red chromosome)

How is it diagnosed: Most babies in the united states and many other countries are screened soon after birth for high levels of phenylalanine in their blood. in the initial step, the doctor pricks the heel or hand of the newborn and collects a few drops of blood on a piece of filter paper (a.k.a gut hire cards.)

What its like living with it: If you have Pku eating can be a problem for you they can eat things like dairy products meat, fish chicken eggs beans and nuts these foods cause high blood phe levels for people with pku
