This morning we woke to this:
Lots of fog.
Although we are in a coastal area prone to fog, this is usually our sunniest time of the year.
So book work it was-- at least for the morning time until that fog burned off.
Graphing: We worked on graphing the average temperature's and distances of the planets in our solar systems. Not surprising the further away the planets are from the sun the cooler they get. Except for Venus and the furthest planets Uranus and Neptune, Venus suffers from a bad case of greenhouse effect bringing its average temperature to 482 degrees Celsius. Temperatures level off around Uranus and Neptune at -193 degrees Celsius because the sun's heat is no longer affecting their temperature.
Hands On: Next we moved on to learning about how to read an utility bill and figure out the different calculations one finds on their bill. Comparing our water bill to an average home of six, we found we love our hot baths and showers.
Experiment! Using these nifty little beads:
That change from white to colors in the sun
we tested the validity of waiting for waterproof sunscreen to dry before getting in the water.
First we applied sunscreen and let dry 15 minutes as instructed on the back of the bottle.
Beads with freshly applied sunscreen.
Next our beads took a 30 second swim.
Fifteen and Thirty minutes later we compared our sun-screened beads to beads without any sunscreen.
Turns out sunscreen doesn't stay put--waterproof or not.
Reading: While we were waiting for our experiment, we finished reading The Kids' Solar Energy Book learning about Active and Passive Solar Systems as well as Solar Cells.
Construction: Wanting to build something new with their Solar Power Kits, E-R and I-E went to work.
The models they built yesterday didn't move very quickly so they hoped that building one model and using two solar cells with it would speed things up.
Mission Accomplished.
