Using https://juxtapose.knightlab.com/ you can generate the image slider for easy comparison of the 2 images. You can embed it with the html code generated like below. Or just copy the link and give to the students
Students can easily compare the 2 images. How effective is the breakwaters in protecting the East Coast? You can see that there the beach has grown bigger, probably due to the greater amount of beach deposit.
A great way to compare the images in terms of spatial and temporal scales.
Changi beach is a popular place for beach and water activities for many. However, the waves are strong and coastal erosion has taken place.
The Changi beach is a place where many families visit to relax and take part in water activities.
However, the coastal land is so badly eroded that it will give way soon.
Sand bags have been placed to protect it from erosion. How effective do you think this will be?
The erosion is so bad that the roots of trees are exposed.
Seawall protecting the another stretch of the coastal land and chalet behind it in Changi. However, you can still see the erosion at work in the foreground.
Look at the coastal erosion threatening the footpath behind it.
Weep holes on the seawall to allow the ground water to be drained so that the soil will not be too saturated and put pressure on the wall and damaging it.

Imagine the waves were so strong that it allowed for surfing on 15 Jan 2021!
Super excited to finally see Tanjong Rimau @ Sentosa again after 28 years! Brought my first batch of students from Rangoon Sec for fieldwork. We were measuring the beach profile and making observation of the cliff features such as the notch and cave. Before the hotel opened next to Tanjong Rimau. Managed to be there via my staycation as I accessed this part of the beach from the hotel's nursery.
Sentosa Nature Discovery has developed a lesson plan based on a video of this area using a drone. I have posted this earlier.
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 strong. Look at the swash
