Experiment with coins in different drinks
Hi friends, it's Esther. Today on this experiment we are going to see what happens when we put a dirty coin in different drinks.
00:00:02
What's your favorite drink?
00:00:10
Here we have some water, milk, lemonade and cola. You also need cups, labels and dirty coins.
00:00:12
First, label your cups like this and pour each drink in each cup.
00:00:21
water, milk, lemonade and coke. Place a dirty coin in front of each label drink
00:00:27
and take a photo. We will do another one at the end. Now put the coins in the
00:00:40
drinks and make a hypothesis. What do you think is going to happen? Which drink
00:00:47
will give us the best results? Write your hypothesis on your lab report. Now we are
00:00:51
going to wait 12 hours. Okay let's take the coins out and check and see what's
00:00:59
happened. Let's start with the coin in the water. This coin hasn't changed at
00:01:16
all. It is still really dirty. What about the coin in the milk? The coin in the
00:01:22
milk hasn't changed much. It's still dirty. What about the coin in the
00:01:29
lemonade. Wow! It's definitely changed. It's a lot shinier. Last of all, the coin in
00:01:33
the cola. Wow! The coin in the cola looks new. It's really shiny and clean. This is
00:01:41
where the camera helps. If you take another photo now, you can compare the
00:01:50
coins before and after. Water hasn't changed the coin at all. Soft drinks
00:01:55
contain lots and lots of sugar and a little acid. The acid gives it a fruity
00:02:09
flavor and stops the sugar from going bad. These drinks are very corrosive. The
00:02:15
acid breaks down the dirt from the coins. Drinks like these are good for cleaning
00:02:20
coins but not too good for our bodies well this experiment was interesting now
00:02:26
you should try write the results and your conclusions in your report bye
