Introduction to Kindergarten Push Pull -Balloon

-Next Generation Science Standard* K-PS2-1

Jack and Lila got me this balloon for Mother’s Day and I decided to make a fun experiment using it.  I recently ordered a kitchen scale so that we could measure how much smaller items weigh.  It was perfect for this Kindergarten Push Pull -Balloon experiment! The scale measures items in grams and ounces.  We used the ounce setting for this experiment, the bottom line is that it is a very versatile scale.

One of the Kindergarten Next Generation Physical Science Standards* states that students should  “[p]lan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.”  For this experiment, we tested if different items would pull a helium balloon down or not.

Step 2: Choose an item and weight it, attach it to the balloon and see if it pulls the balloon down, if it does, choose an item you think is lighter, weight it, fill in the data table and repeat

We started the experiment by weighing this toy helicopter.  It was 1.16 oz. on the scale.

Here is a video showing what happened (sorry for the black bars, I accidentally forgot to turn the phone):

Then we tried this little dolphin, which weighed 0.25 oz.

Here is the video showing what happened with the dolphin:

Then we tried this play dough tool, which measured only 0.18 oz.

A strange little bounce happened with this one as you can see in the video:

This plastic handle only weighed 0.14 oz. so we tried that.

It pulled it down, but not very quickly so we were getting closer…

Finally we tried this monkey, which weighed in at 0.07 oz.

As you can see, the monkey was not enough weight to pull the balloon down.

Therefore the minimum weight to pull the balloon down is somewhere between 0.14-0.07 oz.
