- 5 Petri dishes 
1. 0 mL of water
2. 5 mL of water
3. 10 mL of water
4. 15 mL of water
5. 20 mL of water
- Each dish has 5 mung beans 
- One paper filler in each petri dish

Reasurch Question:
- Will the amout of water in each petri dish affect the amount of growth for the mung beans?

Hypothesis: 
- I do believe the amount of water will affect the growth of the mung beans because if one has to much water, it will drown. However if there is to little, the bean wont have enough nutrience to grow. ]]> 2019-08-29 18:16:48 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/378417636 CER ac23064 https://padlet.com/lisle202/r4qbrt16i6bb/wish/379710496 The amount of water given to the Mung Bean affects the height of the bean in a span of four days. The data shows that with 15 mL of water after a 4 day period, the bean will grow the heighest. With the graph showing the Mung Bean being shorter with less and more amount of water, there is a certain amount needed so it doesn't become dry or drown. We can predict that adding more water than 15 mL will cause the height to become even lower. We can conclude that more water does not necessarily mean that the Mung Bean will grow taller. In conclusion, the evidence shows that about 15 mL of water is the best amount to make the bean grow the heighest in four day. ]]> 2019-09-04 01:41:31 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/379710496 Pill Bug Prelab ac23064 https://padlet.com/lisle202/r4qbrt16i6bb/wish/381802847 Research Question: 
Do pill bugs prefer wet climate or dry climate more. 

Hypothesis:
When seeing pill bugs in their natural habitat, they seem to prefer moist soil more than dry soil. 

Set Up:
There are two optains for the pill bugs to go into. A wet section and a dry section. The bugs have the ability to go into both over a certain amount of time. The amount of pill bugs in each side is recorded after every minute. The average amount of pill bugs after the ten minutes was taken to see which side was preferded.

When conducting an experiment, we concluded that the average amount of pill bugs on the wet side was 6.5 while the amount of bugs on the dry side was 3.5. We took data every one minute for ten minutes. The line graph shows that by the end of the ten minutes, the amount of bugs on the wet side is very much greater than the dry side. According to the Missouri Department of Conservation the bugs have gills that must be kept slightly wet so they don't dry out. Also, the under part of them are pron to becoming dried out if not in a wet envirment. Because of this, we can predict that the bugs would rather live in the moister climate. ]]> 2019-09-10 18:01:25 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/382330487 Hatching Brine Shrimp Prelab ac23064 https://padlet.com/lisle202/r4qbrt16i6bb/wish/399210477 Research Question:
What amount of solinity do Brine Shrimp thrive best in?

Hypothesis:
Between 1.5 and 2.5 precent of solinity the Brine Shrimp are put into, the better they will live. 

Set-up/Procedure:
- Count out 25-30 Brine Shrimp
- Put the 25-30 Brine Shrimp into 5 different petri dushes with tape
- Fill each petri dish with either 1, 1.5, 2, 2.5, or 3 % of salt concentration
- Put cap on container

When conducting the experiment, we found that only .33% hatched when placed in the 1% solinity. The shrimp in the 1.5% solinity had a .63 hatching precentage. But when in the 2% solinity, .83% hatched. This is by far the greatest precentage of survival among the 5 tested. When the shrimp were placed in anything greater than 2%, it went down by about .35% at 2.5 and down more by about .25% when at 3%. All in all, the evidence concludes that when Brine Shrimp live in an environment of 2% solinity, the shrimp thrive the best. ]]> 2019-10-22 18:22:59 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/401061634 Light Lab ac23064 https://padlet.com/lisle202/r4qbrt16i6bb/wish/419259377 Research Question:
How does light affect the Net Pri Productivity?

Hypothesis:
The more light, the more primary productivity/photosynthesis

Set-up:
Materials- lamp, spinich, Co2 measurer, netting, aluminum foil, tube
1. Calibrate the sensor
2. Put the spinich into the tube
3. put lamp up to tube (2 cm) for 2 minutes
    (do this again but with an extra 5 minutes-- after the 2 minutes)
4. Record the amount of Co2 data
Repeat these steps but add netting to tube
After the netting, take off netting and put on tin foil]]> 2019-12-03 18:55:34 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/419259377 CER ac23064 https://padlet.com/lisle202/r4qbrt16i6bb/wish/420423504 The more light in an ecosystem means that Net primary productivity (NPP) increases. When conducting an experiment, we collected data that shows the different levels of light (high, medium, low). The high level shows that -84.78 co2 was recorded. In Medium level, -8.9 co2 was recorded and in the Lowest level of light, 39.86 was recorded thus, having the highest level of co2. The evidence shows that when having less amount of co2 means more NPP occurs. co2 is what is being taken in during the process of photosynthesis. NPP is photosynthesis - respiration.  All in all, as the amount of light goes down during this expirement, the less amount of NPP develops meaning the co2 levels go up. ]]> 2019-12-05 18:58:04 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/420423504 Multi-Colored Light Lab ac23064 https://padlet.com/lisle202/r4qbrt16i6bb/wish/420949172 Research Question:
Is green or white light more efficient for the process of Net Primary Productivity?
Hypothesis:
White light will be more effficient for the process of Net Primary Productivity
Set-up:
Materials- Green and White light lamp, spinach, clear bowl of water, Co2 sensor, tube
1. Calibrate the sensor
2. Put the spinach into the tube
3. put white lamp up to bowl of water for 2 minutes
    (do this again but with an extra 5 minutes-- after the 2 minutes)
4. Record the amount of Co2 data
Repeat these steps but replace white light with green light]]> 2019-12-06 19:08:00 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/420949172 CER ac23064 https://padlet.com/lisle202/r4qbrt16i6bb/wish/421811340 The white light is more effficient for the process of Net Primary Productivity. When conducting an experiment testing the levels of co2, we found after two minutes, the white light had 590 ppm and after another five minutes there was 160 ppm. When testing the green light, after two minutes there was 1,360 ppm and after another five minutes there 1,790 ppm. The white light had 72.8% decrease while the green light had 24% increase. The more co2, the less amount of NPP occuring. Photosynthesis can not occure with green light because the pigment in the spinach's pigment can not absorb the green light causing there to be no production of energy. NPP is photosynthesis-respiration. When putting the evidence together, we find that the white light has a better rate of NPP than the green light thus white light is more efficent.  ]]> 2019-12-09 19:20:05 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/421811340 Potato Lab ac23064 https://padlet.com/lisle202/r4qbrt16i6bb/wish/435324399 Research Question-
  a.)How does the solute concentration affect the movement of H2O across the membrane in potato cells?
  b.)What is the solute concentration of a potato cell?
Hypothesis- 
  a.)The higher sugar solute concentration, the more water in the potato will come out causeing the potato to shrivel. The potato with less amount of sugar and more water will cause the sugar to go inside the potato (in order to even out the concentrations- same thing is happening to the one with the higher sugar) allowing the potato to gain more mass.  
  b.)The solute concentration of the potato cell is going to be equal to the isotonic concentration cell

When putting three potato cores in 5 cups, and filling each with different sugar solute concentrations (0, .2, .4, .6, .8), we see that the mass precentage starts at 21.4% with .1 sugar concentration, then goes negative at .4 sugar concentration continuing to decrease being at its lowest at .8 with -28.7%. The evidence proves that the sugar solute concentration affects the movement of H2O across the membrane at a decently constant rate because of hypotonic and hypertonic movement. 

The solute concentration of a potato cell is at isotonic at .4 sugar solute concentration. The line going through the points crosses the x axis closest to .4 at a decreasing rate. All in all, the solute concentration of a potato cell is at .4 sugar solute concentration with only -2.22% decrease. ]]> 2020-01-24 19:17:38 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/435818920 Native Tree Research Project 3/30 ac23064 https://padlet.com/lisle202/r4qbrt16i6bb/wish/482657176 The tree I have identified is a White Oak Tree (also known as a Quercus Alba). When measuring the tree, the height is around 83 feet high while the diameter is 22 inches. The tree over all has a skinny trunk it seems for the height of it. There are very few leaves on the branches at the moment. The bark has a beige color that is more soft than rough. The tree has many branches as it gets taller and they begin to get skinnier. As the tree grows, the bark begins to look less smooth and starts to look more rough. ]]> 2020-03-30 16:31:28 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/482657176 Native Tree Research Project 4/7 ac23064 https://padlet.com/lisle202/r4qbrt16i6bb/wish/497427289 While observing the tree for 15 minutes I saw very little wildlife visiting my tree. I only saw one cardinal and no squirrels which I was very surprised about. There are normally a lot more organisms in my yard than there were today. There is however a little bit of moss growing on the branches from what I have seen fall from the tree. I would say it is only about 1-2% coverage however.   
The White Oak tree is mostly used for medicine. "White Oak bark is used as a tea for arthritis, diarrhea, colds, fever, cough, and bronchitis; for stimulating appetite; and for improving digestion." The White Oak also provides an important food source and shelter for animals. It also contributes very much to cleaning the air. ]]> 2020-04-07 18:35:05 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/497427289 4/7 ac23064 https://padlet.com/lisle202/r4qbrt16i6bb/wish/497460370 2020-04-07 18:55:57 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/497460370 4/7 ac23064 https://padlet.com/lisle202/r4qbrt16i6bb/wish/497460944 2020-04-07 18:56:15 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/497460944 Native Tree Research Project 4/13 ac23064 https://padlet.com/lisle202/r4qbrt16i6bb/wish/505245056 1. White Oak trees are Monoecious
2. Structures that are involved in its reproduction include male flowers (produce pollen) and female flowers. Acorns are the result of pollination. 
3. White Oaks reproduce both sexually and asexually. They do it sexually by the exchange of pollen between male and female reproductive systems and asexually by the ability to produce both male and female flowers 
4. yes
5. The strategies the white oak tree uses are waiting for the right time of year to reproduce. They rely on the wind to pollinate and germinate the acorns.

My tree exhibits alternate branching
2. My tree has a pinately lobed leaf shape
3. During gas exchange, there are 9 main parts of the leaf that are used. This includes the guard cell, stomta, upper epidermis, chloroplasts, and lower epidermis. First the gas is distributed throughout the stomata and will then go to places that is needed. "Stomatal opening and closing depends on changes in the turgor of the guard cells." When water flows into the guard cell by osmosis, the turgor (pressure)increases and they expand. ATP is required for the guard cell when it draws in water from the epidermal cells which is provided by the chloroplasts. The carbon dioxide goes through this process and comes out oxygen.
4. Advantages: Broad leaves usually grow more quickly and don't take as much energy for plants to grow. They are also very efficient at photosynthesizing because of their large surface area.
Disadvantages: Trees that have needles retain more water and seeds that could hang out until there was enough moisture to take root. They also have lower wind resistance than big, flat leaves so they're more sturdy when grown and less likely to fall down during a storm unlike broad leafed trees. ]]> 2020-05-04 21:27:23 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/550592620 5/5 ac23064 https://padlet.com/lisle202/r4qbrt16i6bb/wish/553374074 2020-05-05 22:27:12 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/553374074 5/5 ac23064 https://padlet.com/lisle202/r4qbrt16i6bb/wish/553374615 2020-05-05 22:27:41 UTC https://padlet.com/lisle202/r4qbrt16i6bb/wish/553374615
