Graphing Jelly Beans

We’ve had lots of fun with our math standard these past two weeks.  From making our own survey on Google Forms and graphing the results to lucky charms and jelly bean sorting and graphing.  Here is a beautiful tally sheet and graph from our jelly bean activity.

Peep Mobiles

We experimented with ramps (inclined planes) earlier this week.  On Wednesday we switched gears (pun intended) and experimented with the simple machines, wheel and axel.  To do this we designed and constructed “peep mobiles” for our little chickie peeps.  The materials that we were able to use were: 3 straws, 4 life saver mints, one square of cardboard, paper, tape, and of course one chickie peep as the driver.  We wanted to see who could build a peep mobile that would travel the farthest on 3 puffs of air.  We quickly realized that in order for a vehicle to be, efficiently, propelled by air it needs a sail.  Here’s a little video from our peep mobile experiment.

Simple Machines

We started learning about simple machines this week.  Some simple machines are ramp (or inclined plane), lever, pulley, and wheel and axel.  On Monday and Tuesday we conducted an experiment to see which ramp would propel our toy race car the farthest distance.

First we made a hypothesis, an educated guess, about which ramp would propel the car the farthest (blue circle).  Then we conducted our experiment, testing each ramp and measuring the distance traveled.  Our result was the longer ramp with the smallest slope propelled the car the farthest (red circle).

Why do you think that ramp worked the best?

Happy St. Patrick’s Day!

Today we had lots of St. Patrick’s Day fun with Lucky Charms.  We checked the hypothesis that there are more clover marshmallow hats than any other marshmallow, in a box of Lucky Charms.  We sorted the cereal from the marshmallows.  Then we sorted and tallied each marshmallow.  Our results:

53 Green Clover Hats, 43 Rainbows, 38 Pots of Gold, 29 Hearts, 28 Horseshoes, 20 Balloons, 19 Moons, 16 Stars, and 189 Colored Clover Hats.  There was a total of 435 marshmallows in our one box of Lucky Charms!

SO … if you don’t count the fancy colored clover hats, our hypothesis was proven correct (at least in that one box).

We graphed our individual marshmallow data

Had some word puzzle races

We even solved a coordinate plane mystery picture!

We had a lot of fun!  What did you do to celebrate St. Patrick’s Day?  What ever you did we hope you had a wonderfully LUCKY day!
