Little Gummy Worm Lab Report

The independent variable for the experiment was the paper towels. The dependent variable was the absorbency and strength. The constants for the experiment were the size of the paper towels that were used, the amount of water, the size of the beaker, the size of the cylinder and the amount of the weight.

For the second part of your assignment, you will apply the scientific method to a real-life situation. You will select a problem that leads to a testable question, similar to the scenarios presented in Part I and explain how you would follow each step of the scientific method to try and answer the question or solve the problem. Note: you are describing only what you would do at each step; you will not be conducting the experiment.

In this experiment there were many possible errors. One of the big errors that was made was that instead of using the plastic water holder to hold the warm water, the experiment was done by putting a wet room temperature paper in one chamber and a another paper dipped in warm water for the other chamber. The data was recorded half way through the experiment but unfortunately it isn't present as of now. Another error that was present was that when the time was started, the isopods were interrupted with a paint brush trying to move them. That could have slightly skewed the start of the data. One other error could have been not paying attention to the time and counting the isopods at different time

One of the most significant errors was the cups used in the experiment. The water in the paper cups leaked out, resulting in the candies not being fully submerged and not reaching full size. The cups were not large enough to fit the gummy snakes, so they ended up breaking into multiple pieces after the experiment was done. The information gathered on the gummy snakes was not accurate because it was difficult to measure the broken pieces. There was also limited time measuring the results due to the fire drill, so the measurements may not be completely

I love gummy worms I been in a gummy worm factory I fell in love with it just the flavors and sweet texture just grab my attention not in that way. I use to buy gummy bears a lot everyday I had a little bit of a sweet tooth my mom just always buy me some gummies at dollar the store. It's kinda funny how i just always on my birthday my mom would ask me what i want for my birthday I would just say money and gummy worms. My mom would just be cool with it she really didn't even care she wasn't buying expensive things that's why.

The Effect of Tonicity and Osmosis on Gummy Bears Introduction Gummy bears work the same as a cell’s plasma membrane because they allow the movement of water molecules in and out of the gummy bear. The plasma membrane is known as selectively permeable because it allows movement of certain molecules and blocks the movement of others. Active transport is an example of a movement that requires a carrier protein and the use of energy to move against the concentration gradient. Passive transport is simply the movement of molecules without the use of energy.

For instance, the light, even though it was on the lowest power, was too strong for the planarians. The flatworms would try to move away from the centre of the dish, where they were less sensitive to the light. This made finding and drawing the planarians very difficult, especially for the faster ones, which resulted in inaccurate observations. Additionally, it is possible that Wormy 2.0’s tail was disposed of while changing the pond water. Because of that, the observations for Wormy 2.0 were incomplete, and therefore the hypothesis was unsupported. As well, there are some factors that contributed to the experimental error that were uncontrollable. Such as the temperature of the classroom which may affect how the worm behaves and it’s survival, or even organisms that may harm the planarian, that live in pond water. There are many more errors that definitely happened, but some may have just gone unnoticed or were simply not taken into

Hypothesis: Mealworms will prefer darker environments over lighter environments because they live underground their eyes(if they have any) will be very sensitive to the light.

In our experiment, we tested the effect of tobacco on the heart rate of worms. We discovered that tobacco does affect the heart rate of Planaria worms. Our data from the experiment proves this. When the Planaria worm was exposed to various amounts of water and various amounts of tobacco extract, the worm moved different distances. Focusing on the amount with the greatest change (2mL), we can see that the worm moved an average of 3.33 squares for 2 ml of water compared to an average of 7.67 squares for 2 ml of tobacco extract. That is a 4.34 square difference. This range provides strong evidence to support our answer because when the worm is exposed to the tobacco extract with the same amount of liquid, the worm moved around faster than

During the paper worm lab, My group worked to solidify our lab data and detect how the worm engages with the universal solvent, water. The experiment focuses on determining whether the paper worm is straight or curvy. Personally, I believe the tightness of the worm prior to conducting the experiment affect your overall data. My data was very distinct from the others in my group because my worm seemed more compact in comparison to other individuals. The independent variable of this lab is the number of drops given by the pipette and the dependent variable of the overall length of the paper worm and the radius change, using both the rating system and just a simple determination (straight or curvy). You may alter the independent variable by for

Universal Statement: There are three phylum of worms. There are the flatworms (Platyhelminthes), roundworms (Nematoda), and the segmented worms (Annelida). Flatworms have long, flat bodies and are usually parasites. An example of one is the Planarian, which are free-living and feed like a vacuum cleaner. Roundworms have long, round bodies and unlike cnidarians or flatworms, have a digestive system that is like a tube, open at both ends.

In the writhing test, administration of acetic acid to control mice produced 56.9+1.2 writhes within30-minute observation period. Pretreatment with the PtE at 50 and 100 mg/kg b.wt. reduced the number of writhes up to 37.3+0.9 (34.45% inhibition) and 22.8+0.6 (60% inhibition), respectively. The standard drug indomethacin reduced the number of writhes to17. 6+0.5 (69% inhibition) at a dose of 20 mg/kg body weight this means that PtE significantly inhibited the number of writhing responses in a dose dependent manner within 30min of injection of acetic acid. The writhing number of the mice given the high dose of PtF (100mg/kg) was even equal that of the mice received indomethacin as depicted in Table

The paper with the fastest time was the crumpled piece of paper with the average time of 0.61 seconds. The second fastest paper was the paper folded in fourth with an average time of 1.10 seconds. Last but not least, the paper that fell the slowest was the regular piece of paper with an average time of 2.52 seconds. Throughout the experiment, a pattern became noticeable. On every single experiment, the crumpled paper tended to fall the fastest, and the regular piece of paper fell the

For instance not every one of the autos were given the same beginning speed when pushed toward each other such that they would impact and the autos were not generally began from the same separation far from each other. (Irregular Error). Extra mistake originates from the way that the attractive guards were put on while the Velcro was (forever appended to the autos) so when playing out the versatile crashes segment of the trial the Velcro would in some cases associate each self by the very tips (insufficient to Take full hold but rather enough to bring about the crash to lose some dynamic vitality). This lone happened2-3 times in any case keeping in mind it is conceivable that this error is the reason the information did not turn out it appears to be improbable since whatever is left of the trials were executed appropriately. (system mistake). Another little mistake could originate from the way that the Xplorer gadget had numerous issues where it would just haphazardly quit taking information. So for this situation the system would be restarted and re-setup. It is conceivable that when utilizing the scale apparatus to see the different vi and vf of truck 1 that the most noteworthy or least

The purpose of this experiment is to test how location affects whether or not the clay caterpillar models will get pecked by birds. Twenty-one clay caterpillars were made and they were made to be 5 cm ± 0.01cm long and 1 cm ± 0.01cm in diameter. Seven caterpillar models were placed in each of the three locations. The three locations are my backyard, the park, and my community garden. As a control variable, all the caterpillars were placed 300 cm ± 50 cm above the ground. An equal amount of caterpillars were glued, to prevent them falling off, in similar areas such as trees, bushes, and fences. This experiment went on for three weeks. Each week is considered one trial. Each caterpillar that was pecked or not was recorded and the data was placed
