Dear RiverRun
Families,
This week we saw how land heats faster than water and cools
faster than water. Two jars were
filled, one with water and one with sand.
Thermometers were placed in
both. We took them outside and measured
the temperatures as they rose, close to every five minutes over time. We did this again another day and then
brought both the jars in to room temperature and watched them cool; taking
readings about every five minutes again.
The children learned how to read a thermometer in both Fahrenheit and
Celsius. It seemed funny to the
children that 70 degrees Fahrenheit,
which we normally see as a pleasant temperature is called 21 degrees in Celsius.
Since we have been looking a lot at
numbers it seems like the right time to explore how numbers came to be (another of the Great Lessons). We all agree that numbers are important and
that we use them every day. The children found many ways even prehistoric man
used the language of numbers to communicate things like how many animals a
hunter brought back or how long until the fruit on the trees come back. We then jumped far ahead in time and talked
about the Sumerians and how they recorded numbers using a pointed stick and
clay. Using clay and sticks the children
copied the symbols (cuneiform) the Sumerians used.
The Physical Education trip to
Flight was a lot of fun. Mark, Tonya,
Rachel, Heidi and Stephanie jumped around with the kids. The rest of the adult’s walked around and
monitored the action. Thank you to all
the parents who drove.
