Combo Chart using Microsoft Excel

Creating combo chart using Microsoft excel is simple especially when you have two sets of data for the Y axis. As shown below - air temperature and relative humidity

This is especially so with climatic graph.

Download from the link below a template which you can use to generate the climatic graph.

Data representation in tourism

Data representation in tourism
We created Scatter graphs and other graphs using infogr.am. 

You can use the following link to calculate how far the country of origin of the tourist is from Singapore:

http://www.happyzebra.com/distance-calculator/farfrom-Singapore.php
We created an account @ http://infogr.am/ - click on "create" and then click on any of the infographics template. 

Double click on the text box and type in your title

Delete the chart and add a new one by clicking on "add chart" as shown below.

 Choose the type of graph you want your data to be represented.

Double click to edit the chart.

Clear all the data.

After you cleared all data,  open the excel file as shown below. Copy and paste the data back to infogr.am

You can also create a map with the same data - click on "add a map"

Demo on land transect using Google Map engine - use the polygon to create the polygon indicating the landuse. you can locate the place by using Google map in which you can refer to the street scene to confirm the area which you are plotting is correct.

Geographical Investigation of Water Quality

How to use the water test kit to check for turbidity, PH value and dissolved oxygen.

Turbidity

Definition:

Turbidity is the measure of the relative clarity of water. 

Importance:

Murkiness can give some clues to what may be in the water. There may be dissolved pollutants or bacteria. However, murky water does NOT necessarily mean there is pollution.

Steps for measuring turbidity:

1.Pour the collected sample water into the white container.

2.Compare the appearance of Secchi disk icon in the container to the chart.

Precautions taken to ensure accuracy of readings:

•Fill up the container to the turbidity line located on the label. Record the result as turbidity in JTU.

Dissolved Oxygen

Definition:

The dissolved oxygen is the amount of oxygen dissolved in a given volume of water, at a given temperature and atmospheric pressure.

This can be measured in milligrams per litre (mg/l) or parts per million (ppm).

Importance:

The amount of dissolved oxygen needed

     to sustain fish life is about 4 mg/l or 4 ppm.   

Steps for measuring dissolved oxygen:

1. Fill the vial with the water collected.

2. Ensure no bubbles visible

3. Insert 2 tablets for dissolved oxygen testing

4. Close the cover

5. shake continuously for 10 mins

6. Observe colour change and compare colour against the dissolved oxygen chart.

Precautions taken to ensure accuracy of readings for dissolved oxygen:

•Vial must be submerged into the white container while filling the vial with collected water. This is to avoid introducing bubbles in the vial.

•Always place the vial or test tube against the white background when comparing collected water with the given chart. 

PH value

Definition:

It is a measurement of acidity or alkalinity of an aqueous solution.

Importance:

Most aquatic animals prefer a range of pH 6.5 to 8.0.

pH can be affected by acid rain or wastewater discharges

If the living conditions have a pH value away from this range, these aquatic animals will either flee or die.

Steps for measuring PH value:

1. Fill the test tube up to the 10 ml mark 

2. Insert a PH tablet into the test tube.

3. Observe colour change and compare colour against the PH chart.

Precautions taken to ensure accuracy of readings:

•Always place the test tube against the white background when comparing collected water with the given chart. 

Kahoot

Kahoot is very similar to Socrative as a free online assessment tool - just that the element of gaming is stronger as the player is given a score based on accuracy and speed. As there are more students who own smart phones nowadays, using Kahoot to do a quick check on understanding with the element of game will definitely engage the students.

It is very easy to create the quiz. Just login to https://create.kahoot.it/

The following screen shoot shows what the students will see on his/her handphone.

The score is updated after every question!

 The winner is announced!

Quizlet

I was introduced to Quizlet http://quizlet.com/ by the ICT mentor community. It's quite simple to create and is great to create flash cards. I have used it to create a set of flash cards to better  sec 1 Geography and water resources.
The students can click on the text and it will be read to them. You just have to input the word/image and its definition/meaning or the question and answer once and the whole study set of flash cards, test and games will be generated.

Choose the mode of study by scrolling down the menu at the bottom right hand corner. I love the scatter game and space race - try it out!
