Dissolving By Olivia Belcher
In this Homework I will be showing you my experiment and how I found out if the following powders dissolved in cold water and hot water, I hope you enjoy it.
I’ll be using: • Hot chocolate powder • Washing powder • Flour • Sugar • Salt • Paprika • Spoon • Glasses (pots)
I Predict: • I predict that the Hot chocolate will dissolve easily • I predict that the washing powder will not • I predict that the salt will get stuck to the bottom • I predict the sugar will break up but not dissolve • I predict the flour will go lumpy • I Predict the Paprika will dissolve
What I’m going to do • I will test all of the powders in the same amount of water and see what happens. I will be doing hot water and cold water and other.
Sugar Sugar before water in Sugar, after 20 stirs and water in
Hot chocolate Before water in Water in
Paprika Before water in Water in and 20 stirs after
Washing powder then flour After water in and 20 stirs Water not in then water in and 20 stirs
Were my predictions correct? • I predict that the Hot chocolate will dissolve easily • I predict that the washing powder will not • I predict that the salt will get stuck to the bottom • I predict the sugar will break up but not dissolve • I predict the flour will go lumpy • I Predict the Paprika will dissolve • Wrong, it dissolved a bit but most lumpy • Wrong, the washing powder did but some didn’t • Correct the salt went down and stuck together • Wrong the sugar did dissolve AND break up • Correct, the flour did go lumpy • The paprika did dissolve but most didn’t and floated on top What I predicted What I found out
No picture were taken during the hot water experiment, but I did record My results.
Have some fun! I did a small experiment with lemonade and sugar and salt
Sugar and salt.... WITH LEMONADE Salt Sugar
My Results • I found that the salt dissolved the most and the sugar took a while but it dissolved in the end! (looks the same but there is change!)It look like nothing but there is something there but the picture is a bit blurred
What I learnt • I learnt that even though it is paprika and salt and things you wouldn’t expect, doesn’t mean that they can’t dissolve. I thought that only hot chocolate was going to dissolve so I was surprised. I enjoyed doing this and it was quite fascinating as I found out the results! It’s better than sitting down and writing: what is dissolving... I’m glad I could do something. I would like more homework like this
Well done! • You have observed closely, good • You have presented your findings on a chart, good recording • You have devised a fair test • You have predicted • You have extended your test and discovered something new. • Excellent science ! • AAA ( 3 stars)
