Gummy bear experiment

Instructions First boil some water to make it easier to dissolve salt into it.

Gummy bear experiment

By Courtney Veyrasset and Lauren Haus Abstract The purpose of this experiment is to examine the concept of osmosis, specifically, how osmosis works.

We will use gummy candies and place them in different solutions with higher osmosis. Our hypothesis, based on the mechanics of osmosis, will be that solutions with higher concentration of water molecules than the concentration of water molecules contained in the gummy candy will expand the gummy candy because water from a higher concentration will move towards an area where water is at a comparatively lower concentration.

Vice-versa, if we place gummy candies in solutions where there is less concentration of water molecules compared to the water molecule concentration in the candy, the candy will shrink. The type of solutions with varying water molecule concentration will represent our independent variable.

The measurement of the candy after several days soaked in the solutions will represent our dependent variable. Each candy and time duration it will soak in the solutions will be the same. As predicted, the candies increased and decreased according to the type of solutions in which they were soaked.

Specifically solutions with greater water molecules than that contained in the candies such pure as pure water and baking soda water solution created candies that were larger than the original size. We concluded that water molecules moved into the permeable candy membrane.

On the other hand, candies soaked in solutions with less water molecule than that contained in the tummies created candies that were smaller than the original size. WE concluded that water left the candy.

A solution with no water molecules isopropyl alcohol did not change the gummy size as expected. The alcohol served as our control factor. In conclusion, this short and easy experiment highlighted a natural process that is important to many biological and natural functions.

The experiment showed that osmosis does not require energy to occur which is important because in biology and the world in general, energy consumption is important key to determine if a process occurs spontaneously or not.

Osmosis is a process that people can take advantage of and we do and with man applications. Introduction Osmosis specifically, the diffusion of water, is an important natural process for cellular activity.

This experiment will focus on the concept of diffusion particularly how it operates. The experiment will use several different solutions to show various levels of diffusion.

The solution will act as the independent variable. The gummy candies will be soaked in the various solutions for an equal amount of time and ten they will be measured by length to see if they had shrunk or grown.Purpose: The gummy bear lab was completed in class because the class was practicing how to write a lab report and the class was also learning about the scientific method.

The problem for the lab was to find out what would happen to a gummy bear when it was placed in water over night.

Gummy Bear Experiment Gummy Bears do some interesting things when put into different liquids. In this experiment, we will find out what will happen when we put the Gummy Bears into water, salt water, vinegar, and baking soda water. Part A: 1. Fill out the Scientific Method Chart.

Candy Chemistry Experiments. The gelatin makes the Gummy Bear act more like a sponge by absorbing water instead of being dissolved in it. Take this experiment to the next level and check out all of the science fair ideas for the Mentos Geyser here!

Related Experiments. Observing Osmosis Background Information: Molecules are in constant motion, and tend to move from areas of higher concentrations to lesser concentrations.

Gummy Bears are popular candies made of gelatin, starch, and sugar. Gummy Bear Diffusion 2 M. Poarch – A gummy bear is dropped into the liquid and immediately begins to combust. The heated mixture ignites and oxidizes the sugar in the gummy bear in a violent, exothermic reaction.

The gummy bear explodes because the combination of one gummy bear which is composed mostly of sucrose with molten potassium chlorate the gummy bear explodes. Diffusion Lab Mitchell T. Heaton Introduction: This is a very basic lab that helps clarify the concepts of diffusion and osmosis.

Diffusion is the tendency for molecules to spread out evenly into the available space. Osmosis is the diffusion of water across a selectively permeable membrane. These concepts will be shown using the elementary example of water and gummy bears.
