Photo interpretation using Jigsaw planet

Learned this from Lesson posted on edumall by Gerald Tay. http://subjects.edumall.sg/cos/o.x?c=/subjects/pagetree&func=view&rid=6755 (you must login to edumall to see this) He actually made use of the jigsaw planet to create jigsaw puzzles online to stimulate the student's interest in the learning of the topic "Geography of food".

The jigsaw puzzle is quite an interesting tool - I will actually use this in photo interpretation for the topic on coastal studies - http://www.jigsawplanet.com/?rc=showpuzzle&pid=330ea41ef34d&ret=%2F The teacher create the puzzles online and the students will have to highlight the main features on the photographs and relate them to what is being taught - eg. landform, process, coastal protection etc.



Play the "FB IMG 1554079059390" puzzle! https://www.jigsawplanet.com/?rc=play&pid=38ebac73ffc7



What are the coastal features shown in the photograph? How are they formed? 
Which type of waves are associated with the formation of the features shown in the photograph?

Quite a number of teachers are also using it as clues for digital escape room!

Compass bearing simulation using Geogebra

Awesome sharing by Wei Sern from SGLDC on creating interactive exercises in Geogebra. This is useful especially when embedding html code is available end of June in SLS. You can also use the code to embed on Google sites and Blog (like the one below)

Reading compass bearing created by Wei Sern:

https://ggbm.at/hydx8tm2



1. Check the box next to "Use Protractor" so that the protractor will appear.
2. Read the question on where to measure the bearing from.
3. Select "Move compass to A or B" as shown in question.  E.g. point B
4. Drag the protractor and rotate it so that O points to the north. (If the angle is more than 180° then rotate the protractor with 0 starting from South and the read the angle. Add 180°to the reading.)
5. Drag the pin head so that the line intercept with the point it is measuring to e.g.point A
6. Read the angle from the protractor and enter the number into the keypad with the degree symbol.
7. Click on "Enter Check".



If you want to get the code to embed, you need to download the GGB file  (e.g from https://ggbm.at/hydx8tm2)and then upload as your activity in your GeoGebra account. Then in your GeoGebra account you can follow the following steps to get the code to embed in you blog or site:

I have commented earlier how I missed the earlier ETD game of using interactive game to learn compass bearing. Learned from him that compass bearing is also learned in O level E Maths and that he could create the simulation in geogabra.  Students kinestatically learn how angle bearings of one location from another is referenced. It allows the sttudents to move a virtual compass and then input the value of the angle.

The original exercise had some drawbacks when used on a mobile phone, hence he had improved on it by including a virtual customized keyboard which allows the activity to be run on phone browser with better graphics control and interface.

He also mentioned that the protractor tool can be made into a template file and inserted into any existing good quality Geogebra geometry activity resource without too much effort! It can be downloaded from

Interactive media for map reading on SLS

So happy to find that interactive media from ETD is now included in SLS. Would really hope that the older interactive e.g. grid reference - fun with building and grid bearing - flying a plane are also included! The only draw back with the existing one is the absence of 4-figure and 6-figure grid reference. However still love the games Sailing with bearing and Quest of Arudra Island.







Added the interactive media on lesson review - "How to read a map (part 2) features of a map."



Added the interactive media on the game  "Quest on Arudra Island"



Added the interactive media on the game  "Sailing with Bearing"

To overcome the issue of the lesson review not showing the 4-figure and 6-figure grid reference, thinking of using the thinking routine to get the students to draw it out.

Using Google Sheets to analyse and represent data for coastal GI

Sharing how I use Google Sheets to generate scatter graph, comparative line graphs and beach profile for the Coastal GI in helping the students to analyse and represent the data they have collected at ECP.

Creating Scatter graph with best-fit line






Creating a Comparative Line Graph using a Combo Chart with two Y-axis







Creating a Beach Profile graph by inserting a line chart.

Google Earth Game

Remember my earlier sharing on Google Earth? http://geogshare.blogspot.com/search/label/Google%20Earth?m=1 

Seemed a lot more exciting with introduction of a game "Where in the World is Carmen Sandiego?" using Google Earth shared by freetech4teachers Great for EL and Geog!

To play Where on Google Earth is Carmen Sandiego? simply go to g.co/carmensandiego and start "interviewing" witnesses by clicking on the magnifying glass.

When you click on an interviewee Google Earth will automatically zoom-in on the location of the interview. Just like in any other use of Google Earth, you can zoom and pan around the area of detail.
Great for learning about places around the world!

After talking to the witnesses, use the information to make your best guess as to where you should fly to next from a given list to pursue Carmen Sandiego.

I think using this concept it can be applied on virtual amazing race too. Tried that by place marking but this is more fun. Will try that with students one day!


      


      

Update:
Carmen Sandiego is back!
Another game to help Carmen Sandiego recover Tutankhamun’s Mask. Le Chevre, a master climber and her classmate of  at VILE Academy, has stolen the priceless artifact.

Coastal studies in Sentosa

A virtual fieldwork via a video captured by drone on Tanjong Rimau and rocks on the island in a workshop conducted by Sentosa Nature Discovery followed by a walk on Imbiah trail. Saw the Imbiah falls along the way. Thankful that we had a very enriching experience with our guide, Tammy, from SND.

The two programmes which we can embark on in Sentosa for Geography

Differential erosion - conglomerates and sandstones. Did not cross my mind to show the students the different types of rocks to show them that. Time to dig out my old collection! Indeed students can make connection to their learning if they can see it with their own eyes. 
Used to bring the students for fieldwork at this part of Sentosa in the 90s. Just realized it is called Tanjong Rimau.  The observation of fissures, the notch, the caves on the cliff, and the action of plant roots on weathering. The measurement of the height of the cliff and the gradient of the transect along the shore platform. Had a very good mentor, Alice, back in the 90s.

Where the rock beach is - didn't know there are corals too. Used to bring the students to the coralarium which had made way for the golf course. Students love the touch pool and learned more about the fringing reef.

Safe to swim!

Actually the waves are quite storm. Look at the swash

This was where the old coastline was with the spring water
