We have done several activities this week to help celebrate President’s Day.

Monday, we played a game where we learned about heads and tails.  I made up my own version last year:

heads-and-tails-penny-graph

I have small 3oz. bathroom cups for each child and one penny.  They put the penny in the cup and shake a few times and dump it out on their paper.  They record on the graph; by cutting out the appropriate picture.  The penny side that gets its graphing column filled up first is the “winner”.

Wednesday, we played the water dropper game.  Each child made a prediction about how many water drops they thought it would take to fill up one side of a penny before the water spilled over the side.  They wrote down their prediction and then the actual number.  I used droppers–I got them from Steve Spangler Science (less than $10.00 for 100 of them).

(In this picture you see we are using plastic medicine droppers–this is from last year–I forgot to take pictures!!)

Thursday, we noticed that some of the pennies were dirty, so we started thinking about ways to clean them.  We made a list of things we could try:

hair spray

water (hot, cold, and soapy)

lemon juice

milk

vinegar

peroxide

Coke-a-Cola

baking soda

We will be trying these out tomorrow and letting them sit over the weekend, so we’ll see what the results are!!  Tomorrow, before we begin, we will make a hypothesis and some predictions about what will happen.
