Investigating gases

In our solids, liquids and gases topic, we have been investigating whether gases weigh anything. The children identified the different states of matter within a bottle of lemonade. They then made their predictions and stated if they thought the gases within the bottle weighed anything. To carry out the investigation they weighted their bottle of lemonade and then shook them vigorously for 10 minutes. Following this they weighed the bottle again and found the results rather surprising…The gases did hold a weight!
