lipstick

$ Store Activity Name:   Lipstick and Lips
Concepts / Skills addressed:   measurement (weight)
Approximate Grade Range:   4th - 6th
Materials:   Dollar store lipstick, 2 inch x 2 inch piece of plastic wrap, digital scale (most likely NOT from the dollar store), a copied sheet of ten identical pictures of lips. 
The General Idea:   Wrap the plastic wrap around the lipstick which has been carefully removed from its tube.  Leave a bit of the lipstick exposed.  Weigh it (in grams) on the scale.  Carefully apply the lipstick to the ten set of lips on the sheet so that all are covered.  Re weigh the lipstick and find out how much was used to cover ten sets of lips.  use this to determine the weight needed to cover one set of lips then figure out how many lips can be had from one tube of lipstick. 
Extensions: 
Cut out from magazines pictures of various celebrities (female and male) who have various sizes of lips (Include someone like Mick Jagger!)  Make ten copies of each picture and glue each celebrity group of ten pictures onto a large piece of paper (ten pictures per each celebrity).  Try to keep the size of the celebrity heads as close to one another as possible.  Do the same things described above, just using the celebrity lips.  Some celebrities will require more lipstick than others.  Predict who needs more/less and then find out.
