Gummy Bear Lab Report

1. The volume of the gummy bear increased when we put it in water for twenty four hours. Originally, the volume of the bear was 1.75cm3. After the bear was in the water for twenty four hours, its volume increased to 10.5cm3. So, to find the change in volume, you subtract the new amount from the original. 10.5cm3-1.75cm3= 8.75cm3. The change in volume is 8.75cm3.

First, each table received 2 gummy bears. Each gummy bear was measured for their height, width, and thickness in mm. Secondly, 150 ml of water was poured into a cup with your group number on it. Then after we recorded our measurements of the gummy bears, one gummy bear (A) was placed in the 150ml cup of water, while the other gummy bear (B) was placed in the Ziploc bag. The gummy bears were measured again after 24 hours. When we checked the gummy bears after 24 hours, gummy bear B in the bag stayed the same, while the height and width of the gummy bear A in the water grew and the thickness shrunk. Originally, the gummy bear A in the water weighed 2.57 grams, measured 12mm thick, 10mm wide and 17 mm tall. After the experiment, gummy bear A

There are four main characteristics of the scientific method: observation/measurements, make an assumption, test the assumption, and revise the assumption. The first stage we make an observations. For instance, I notice that my peppers in my garden are not growing well. I am going to assume this is because I did not water that area well enough. So I am now going to test my assumption. This is done by watering the peppers in my garden more frequently. Lastly, I am going to see if my assumption was correct. If my peppers only needed more water, they will begin to grow more rapidly. It is also possible that my assumption was wrong, and that my peppers were getting enough water; however, there could be something wrong with the soil, temperature, etc. These are the four main characteristics of the scientific method; it is important to note that our assumptions sometimes be wrong, thus it is always important that we test our assumptions to make sure we are correct.

Purpose: The purpose of this gummy bear lab is too figure out what different types of osmosis and diffusion can be seen during the lab. Also too see what solutions will cause the gummy bear to be isotonic, hypotonic, or hypertonic. This will benefit people that may eat a lot of gummy bears along with drinking sodas and juices, or water this may cause you to become more dehydrated. This will help people who like to eat gummy bears but don’t know what's best to drink with them.

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.

According to the scientific method, I should create a new experiment by making another hypothesis.

When the different gummy candies are placed in water for 24 hours, the size and appearance changes due to osmosis. The mass, volume, and length of the three different gummy candies were measured before and after the experiment, and the changes shown after the experiment were significant. Out of the three gummy candies used in the experiment, the gummy bears showed the least amount change in mass, volume, length, and in average changes. The gummy fruit had the most consistent results out of the candies. The results gathered showed that the gummy fruit had changes that were in the decimals, such as in the average change.

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.

The purpose of this experiment was to investigate the effect that different liquids would have on gummy bears. To do this we brought in different liquids, such as Fanta soda, salt water, water, and baking soda water. My hypothesis is, If you put gummy bears in different liquids then they might dissolve or enlarge. This experiment was tested on 9-14-17 and my group and I started gathering data, we started with 1 minute, 5 minutes, and then 24 hours. There wasn’t much change in the 1 and 5 minutes, the real change happened overnight. The next day of this experiment the gummy bears had mostly enlarged and softened, there was one that accomplished to do the exact opposite, the salt water gummy bear decreased and hardened. I believe that the salt

In this project, C. Elegans are hermaphrodite worms that will be used since they are easy to maintain in lab, as well as have short life cycles. The gene that the project attempted to knockdown in C. Elegans with RNAi treatment is the unc-22 gene. RNAi disrupts gene expression in the presence of double stranded RNA (dsRNA) that is complementary to target gene sequence. The unc-22 gene codes for a muscle protein called twitchin in wild-type worms. The Unc-22 is required for muscle regulation and maintenance in C.Elegans. To verify that the RNAi treatment worked, would check the unc-22 mRNA levels in the worms, in addition to phenotype observation.

In this experiment I used green gummy bears, 2/3 cup of water, 2/3 cup of milk, and 2/3 cup of Dr.Pepper. I soaked the gummy bears in Dr.Pepper, milk, and water three different times for two hours each. On my first try soaking a gummy bear in water it measured 3 quarter of an inch; second try soaking it in water the gummy was an

First we measured two gummy bears and figured out their mass. We put one gummy bear in a ziplock bag and sealed it. Then we measured out 150ml of water and placed it in a cup. We left the gummy bears out for 24 hours. The next day we took the gummy bear in the bag out and measured it to see if it had changed. we then drained all the water out of the plastic cup and attempted to get the measurements. We found the mass for the two gummy bears and then figured out the change in volume. The change in volume for our gummy bear was 121mm for the gummy bear in the plastic bag. Then 4492 mm for the gummy bear in the water. The reason the gummy in the water expanded is that the movement of the water molecules into the gummy bears made it expand. Osmosis

Question: Will changing the water temperature affect how quickly a gummi bear dissolves in water? Hypothesis: If the temperature of the water is warmer, then the gummi bear will decrease more quickly in size than compared to cooler temperatures. Materials: Gather the following materials including: •safety equipment including: goggles, gloves, and apron •two 25 mL beakers •one graduated cylinder •one thermometer •one hot plate •8 red gummi bears from the same brand •20 mL of normal tap water in each beaker •one balance measured in grams •forceps •paper towels Procedure: 1.Gather all the materials listed above. 2.Include data tables in your experiment by doing two trials.

The purpose of this experiment is to conduct what happens to gummy bears when we put them into different liquids. When we were done we gathered data and saw that the gummy bears ended up with different textures and sizes. There were only some minor differences. For water after a day, the length changed, the width, height, and mass. For salt water only the mass changed, before it was 2.6 and after it was 1.5 grams. The next liquid is sugar water, and for that liquid all the of the data changed. The length was 3 cm before, after it was 3.5 cm. The width of the gummy bear was 3 cm before, after it was 1 cm, and after it was 1.5 The height was 2 cm, and changed to 1 cm. Lastly is the mass, it was 2.6 and the after it changed to 5.1. The
