Which liquid is the quickest?

In our science lessons we are looking at ‘States of matter’ so today year 4 planned an investigation to see which of our five liquids: tomato ketchup, water, cooking oil, orange juice or marmalade will be the quickest to reach the end of our slope. We made our predictions before carrying out the investigation. We discovered that water was the quickest because of its consistency- we are still waiting for the tomato ketchup and marmalade to reach the end. Which will reach the end first between the tomato ketchup or marmalade? Keep watching!
