Jupiter – 10/31/2012

According on the Stellarium, GRS will start to transit at around 3:00am but it did not happen until 4:00am this morning. I wish I could wait till 5:00 am but I felt tired already. T_T

Image was captured using Meade ETX 125 and Philips Toucam Pro. SharpCap, Castrator and Regsitax were used for acquisition and processing of pictures.

Modeling Activity on the Law of Universal Gravitation

In my desperate effort to my an inch away from traditional lecture method,  I tried to let my students do a modeling  activity on the Universal Law of Gravitation. Good thing PhET Gravity Force lab was available and as well lots of teacher made inquiry / modeling based activity can be reviewed and modified to specific use in class.

Steve Banasiak’s activity on the gravity force lab is one best and I recommend its use. The link of the activity can be found here.

The activity allows them simulate force of gravity between two objects then find the relationships of masses ( mass 1 and 2) to the distance and force of gravity through tables and graphs. Student are asked to find the formula in the relationships and also calculate for the gravitational constant (G).

You can also do differentiated instruction by doing homogenous grouping. Let the advanced group do an activity with less instruction, challenging them to think how to go through with it while have the less advanced group with a more detailed instructions and guide them as they do their work. I find it difficult at first but it really pays off well in the end.

Having them find the formula themselves (and the gravitational constant) is more meaningful than posting it on the board.

I’ll post student responses soon!

Jupiter – 10/13/2012

The sky was generous for a few moments until the clouds came rolling in. Luckily, we were able to capture a few frames of Jupiter.  The image was taken at Subic during the Philippine Astronomical Society Planning Session using Celestron C6 SCT on EQ5 mount using Philips Toucam
