http://bit.ly/2L9NH0b
An Activity for Preschoolers:
A STEM activity promoting Science.
Before You Begin:
Make sure to clear enough space on a flat surface for children to do this activity.
Activity Goals:
To support observation skills.
Furthermore:
Use the timer sets to indicate a time limit in the classroom. For example, turn a time over and challenge the children to have the room clean before the timer finishes.
1) Have each child select a liquid timer.
2) Let the timers drip and have children make observations.
3) As a group, ask each child to identify and discuss characteristics of their timers.
4) Write their responses down on a chart.
5) Repeat for various times.
6) Another option is to have children guess the amount of time each liquid timer set has. Use a stopwatch to determine real time.
