In my project I wanted to find out which liquid would make the gummy bear the biggest and will color affect the growth. In this candy science experiment, we compared gummy bears left in water to those placed in salt water. 3. Hypotonic Solution (Gummy Bear Experiment). 4 Hypotheses: Circle your choices to create your hypotheses (2 points) 1. Procedure: 1. 3) They should then vote on what variable they would like to test. Circle your answer. They listed the dependent variable (mass and length of gummy bear), the independent variable (the solute – what was added to the cup of water) and the constants (amount of water, amount of solute, and time the gummy bear will be in the solution) It is what is held constant and is used as a baseline for comparison. Experimental variable is another name for dependent variable. So we added salt, a little bit at a time, to a cup of boiling water until no more salt dissolved. I thought that the sprite would make the gummy bear the biggest because of the carbonation.. When studying Egypt, or preparing for an extra spooky Halloween you might consider making a chicken mummy.But chicken mummies take about a month to create, so seeing the process of osmosis can be very slow.To see the process of osmosis quickly you can do a gummy bear osmosis experiment. I like to have the water already poured into beakers or plastic cups prior to the kids arriving. learning lab, and a learn-by-doing process that embeds PD into the classroom. - Represent the current, well-supported explanation about some aspect of the natural world. Since osmosis has to do with the movement of water in living things, we usually talk about water moving in or out of cells. This takes the place of individual lab reports which take a lot of time to grade. The variable being manipulated or tested in the experiment. Overview of activity:  This is a 3 day activity. The control group was the gummy bear soaked in regular water. ... if you open a faucet (the independent variable), the quantity of water flowing (dependent variable) changes in response--the water flow increases. 5) Have students convert their question in to an experiment. A merchant wants to mix gummy worms worth $7 per pound and gummy bears worth $3 per pound to make 30 pounds of a mixture worth $4.60 per pound. The dependent variable is the variable that changes in response to the independent variable. The gelatin makes the Gummy Bear act more like a sponge … See details for more info.
