Lab Report On Gummy Bear

Variables:

Independent: the type of water we use.

Dependent: is the size of the gummy bear after it was soaked in regular water, salt water,baking soda water, and vinegar.

Constant: the dependent variable was the size of the gummy bear after it was soaked in regular water, salt water, baking soda water,and vinegar.

Evidence:

In my data table it shows that the gummy bear put in water grew 0.5cm more than the other ones put in the other liquids.

Resonong:

The gummy bear in water grew bigger because the water has minerals in it so it can grow more, I know that the one in water is bigger because in the data table it showed the amount of change and the gummy bear in the water grew 0.5cm more than the other gummy bears put in liquid.

Reflection:
I wasn’t surprised when the results showed that the gummy bear in water grew bigger.

In the 1st day it showed that the gummy bear put in vinegar was getting bigger but over time the gummy bear in water grew even more bigger as the gummy bear in vinegar started disintegrating slowly, and parts of the gummy bear started falling off.

Next testable question:

Does the gummy bear change if it gets put under a lamp?

Does the gummy bear gelatin affect the process of the gummy bear experiment?

Hypothesis:

If you put the gummy bear in Vinegar it will not get bigger also if you buy it in the baking soda it will also not get bigger. The water will make the gummy bear get bigger because of the material that it made by the gummy bear.

Procedure:

1.In each of the four - 100 ml beakers or cup:

Pour 50ml of WATER into into one beakers or cup

Pour 50ml of VINEGAR into one beaker or cup

Mix 50ml of WATER with 15ml (1 tbsp) of BAKING SODA in one beaker or cup

Mix 50ml of WATER with 15ml (1 tbsp) of SALT in one beaker or cup

2. Drop a gummy bear into each of your prepared beaker or cup and place the beaker or cup

Onto the labelled sheet of paper under the correct heading. Let sit for one

day
3.on day 2, remove the gummy bears from each mixture and use a paper towel to dry it off to prevent it from dripping all over the place. Make sure to keep the liquids in the same beaker or cup.
4. Measure and fill out the data table, measure each gummy bear. Put back the gummy bears into the liquids.
5. On day 3, remove the gummy bear from each mixture and use a paper towel to dry it off to prevent it
From dripping all over the place. You may throw away the liquids.
6. Measure the gummy bears and put it into your data table then compare and see which one grew the most.
