Science Task


Today's Science task is based on a really FUN experiment! It's called...

'Soaking Gummy Bears!'



Over this half term we will be looking at working scientifically and developing skills based on this aspect.

Over the next two weeks we will begin looking at the 'Gummy Bears' experiment. Today will be predicting what we think will happen first and then do the experiment. We will observe and see what happens using the record sheet to note down observations made. Next week, we will review what happened smiley


Have a look at the experiment below...


*If you are unable to carry this out, don't worry as you can still predict what you think will happen and then we will post the results next week! 



This experiment is open for exploration and discovery, so kick things off by asking your child what they think will happen to a gummy bear in water. Will it dissolve? Will it shrink or grow? Will it fall apart? How long will it take? Don’t forget to use the sheet below to write down ideas so you can compare what was predicted with what actually happens! You’ll start to see results in just a few hours, and you’ll definitely see big changes in size in just a day. 


You will need...

  • gummy bears
  • water (3 cups)
  • salt
  • sugar
  • bowl (3)



1. Heat 1 cup of water over the stove. Slowly add salt to it and stir. (You’ll need around 7-9 tablespoons.) Continue adding salt until it no longer dissolves and a few salt crystals remain at the bottom. You now have a supersaturated salt solution. 


2. Pour the salt solution into a bowl. Let the mixture come to room temperature.  Repeat steps 1 and 2 with sugar instead of salt to get a supersaturated sugar solution. 


3. Finally, fill the last bowl with normal water. You now have three bowls filled with different solutions. 


4. Take your gummy bears and place a few in each bowl. Remember to save a few as control tests. Let the bears sit in the bowls for 12-72  hours. How do you think the bears will react with each solution?



Now observe the bears! (Take a picture of what the bears look like at this stage) 

Are some bears more jiggly than others? Did the colour change at all? Can you find a way to shrink the largest gummy? Continue to experiment by soaking your bears in different liquids and different concentrations!


Use the record sheet below to keep track of your bears! We will review this next week smiley



I'll be available to contact through our class email -

So please do contact me for advice or if you simply want to share what your child has done! smiley
