Oil exploration – Science Experiment

September 9th, 2014

Tags: ,

Yesterday, we read about oil exploration and so, we pretended to be one of the oil explorers.  I found the directions online: https://suite.io/alexandra-matiella-novak/1fnw20n

We filled a shoebox with sand and small stones and somewhere in between, I hid a small plastic box with green colored water to represent oil.  We closed the shoebox and we taped a graph paper on it.  Marked the directions for North, South, East and West.  Then the kids started exploring for oil by digging into our pretend earth with skewers.  When they hit the spot, we used a big dropper to suck out the oil.  Kids really had fun doing this.



Comic Strip – Lego Club September 2014

This month’s Lego quest was inspired by one of the creations of John Gannon.  He made a comic strip for Lego fair.  Basically, he made different scenes to tell a short story.  I loved the idea so much that today we divided the kids in groups to let them create a story and use Legos to tell their story.  Everyone did amazing job.


Conductor or Insulator – Science Experiment

September 5th, 2014

After reading about conductors and insulators we went online to find exciting experiments to reinforce our lesson for the day.  I found the following conductor and insulator experiments online.  Our first experiment was to wrap warm water glass jars in different materials and note the amount of reduction in temperature from the water in about 20 minutes.  We warmed each glass jar filled with water in microwave for 1 minute.  Here is a visual tour of all the steps of our experiment.

We found that highest reduction in temperature (15 degree F) was from the glass jar wrapped in bubble wrap and least (0 degree F) from the one wrapped with aluminum foil.  The amount of reduction in temperature from both the glass jars wrapped in cotton cloth and plastic Ziploc bag was 5 degree F.  The amount of reduction in temperatures from the glass jar wrapped in brown paper bag was 10 degree F.

Conclusion: From all the various materials that we tried, aluminum foil will keep the food warm longer as the reduction in the temperature is the least.  So, in this case, aluminum foil is the best insulator.

Our next experiment was to note the temperature when the water starts boiling (212 F).  Then we put a steel spoon, plastic spoon and a wooden craft stick in the boiling water for about 20 min.

We noted that the steel spoon was the most hot to touch and the wooden craft stick the least.

Conclusion: Steel is the best conductor and wood is the best insulator amongst the three.  Plastic falls between steel and wood.

We’re Going on a Bear Hunt

We thoroughly enjoyed reading We’re Going on a Bear Hunt.  After reading the story we ate berries and honey.  Also, I made an edible bear for Arjun using crackers, olives, raisins and fruit loops.  Kabir made his own edible bear including grass (olives), river (blue fruit loops), mud (brown mushed bread), forest (olives), snowstorm (almonds) and cave (meatballs).

I printed out printables from Homeschool Creations.  We enjoyed playing the game based on this book.

Arjun did a good job sequencing the events.


The most memorable moment was to act out the entire book using props.

Then, we went back to:

We’re not going on a bear hunt!

Measuring Time – History of Clocks

August 23rd, 2014

We read about the history of measuring time.  Kabir chose to make two types of clocks out of all the different types of clocks we read in history – candle clock and water clock.

Candle Clock

First, Kabir made a mark on a candle for every centimeter.  The candle was 8cm long.

We lighted the candle at 2:00 P.M.  The first two centimeters of the candle burnt in 10 minutes each.  The subsequent centimeters burnt in 20 minutes each.  We realized that this was because of the shape of the candle was much narrower for the first two centimeters than for the subsequent ones.  It took longer than 20 minutes for the last few centimeters of the candle to burn.  We forgot to register exact time for the last few centimeters of the candle.  It took 3 hours and 40 minutes to burn the whole candle.

Conclusion: Assuming all candles have exact same height, we can use candle to measure time.  We will know that it should take little more than about 3 and a half hours for each candle to burn completely.

Water Clock

We marked inside of a tin container in inches.  The container was 6 inches high.


We made a very small hole at the bottom of the container.


We poured in the water up to the rim at about 11:00 A.M.  1 inch of water got out through the hole in three minutes.  The whole container, though, took 21 minutes to get empty.  It should have taken 18 minutes.  This was because the hole was a bit too high, and we didn’t realize that until the water in the very bottom was the only water left and was not coming out.

Conclusion: If we have a standard marked container with a tiny hole at the very bottom, it is possible to tell how much time has passed using this water clock.
