Aim/objective: To determine the effect of carbon dioxide concentration on the rate of photosynthesis.Problem statement :What is the effect of carbon dioxide concentration on the rate of photosynthesis? Hypothesis When the concentration of carbon dioxide increases, the rate of <span>photosynthesis also increases until the rate becomes constant.</span>VariablesManipulated : Concentration of carbon dioxideResponding : The rate of photosynthesis// The number ofbubble releasedper minute<span>Constant : Light intensity, temperature/ Size of plant</span> Apparatus and materials:Materials :Elodea/Hydrilla ,different concentration of sodium bicarbonate,distilled water Apparatus : Beaker, boiling tube, clip, table lamp, filter funnel Technique :Count and record the number of bubbles produced / released in 20 minutesusing a stopwatch.Procedure:1<span>.Diagram of experimental setup with at least 5 functional labels.</span><span>2.Fill a boiling tube with</span>150 ml of 1%sodium hydrogen carbonate solution. <span>3.Fix a paper clip / plasticine to a sprig of aquatic /</span>Hydrillasp. plant.4.Submerge / put the aquatic plant into the boiling tube containing1% sodium hydrogen carbonate solution.5.Put the boiling tube into a water bath at room temperature (20-30oC). 6.Place the boiling tube at distance of 50 cm from a lighted bulb. 7.Put aside the boiling tube for 5 minute (for the aquatic plant to adjust).8.Start the stopwatch.9.Count the number of bubbles release in 20 minutes.10.Record the result is a table.11.Repeat steps 2 until10 using 2%, 3%and 4%of sodiumhydrogencarbonate solutions. 12.Calculate the rate of photosynthesis.(Rate of photosynthesis = Number of bubbles/time)13.Precaution : Count the bubbles only after the rate becomesconstant. DataInclude the following titles with units:-Concentration of sodium hydrogen carbonates solution (%)-Number of bubbles released in 20 minutes -Rate of photosynthesis (number / minute) Conclusion:When the concentration of carbon dioxide increases, the rate of <span>photosynthesis also increases until the rate becomes constant. Hypothesis</span><span>is accepted.</span>
Well for me, I think i'd say <em>CAT TRAINING</em>.
Here's an example. My newest cat is still learning how to come to the food in the kitchen, and come at times when she needs to eat even if already eaten in the morning.
<u>So before today, I've been trying to get her to come just by placing the food down. But she doesn't give a response to it. Next I try a bell alone, and some other jingling or noise makers. Still no response of her coming to me at all. Then I tried placing the food down while ringing the bell, she's starting to understand, but still not a very good response. I assume in a few more days, she will understand that the bell/other noise means COME TO ME. That is a conditioned response i'm hoping to get soon. </u>

<h2>HAVE A GOOD DAY!</h2>
Similar results in multiple tests of the claim is an example of a scientific claim.
<h3>What is Scientific claim?</h3>
This is defined as statements which are made based on experimental results in the broad field of science.
The results gotten from the experiment is usually compared with that of others to check for similarity so as to ascertain its validity. This is therefore the reason why scientific claim comprises of different tests and observations.
