Question

Where do we use the process of recycling and when do we use it ?

Answer 1

Flip the bottle and time the water. Mark with a line at each minute. Flip and do the same on the other bottle so both sides have the minutes marked.



The water clock can be used as a regular timer for games or activities.  Add colored water to make it more interesting! My kids have been totally obsessed with this since I made it!
