The blue piece had always been loose. And drops easily. Didn’t noticed it drop as I was on my way to class yesterday. Unfortunately, couldn’t find the piece as I retrace my step.
RIP. Had it since my practicum days… time to buy a new one.
Bought this years ago… with other tools for this chapter is a stethoscope (which really works!) and an oxymeter (clipped to finger to measure oxygen level and pulse rate). Those were the days being a young, enthusiastic teacher 😛
Oh, btw this model is the same size of a typical child’s heart.
Artifacts from a project years ago after I taught them parts of a flower and adaptation of insect and wind pollinated plants. So proud that quite a number of them actually put in so much effort for it. The final products were so good that I placed them on display at the back of the Bio lab. The Bio lab is one of the venue for guests whenever we have school visits, so it’s definitely a good idea to put them on display there.
Their task was to design their own flower using any materials. Then, we had show and tell for them to describe the features of the flower they had created, using ideas of pollination.
This is an activity I usually carry out for lesson on part of respiratory system- Model making using straws.
Straws of various sizes and Q-tips are provided foe them to make the model. Straws that I use are bubble tea straw, regular straw and coffee stirrer.
They simply cut the items and tape them to a large piece of white paper provided.
Here’s a sample of the final product.
Did a simple role play to demonstrate the transport of blood through the heart, to the lungs and body. As the “blood” move along, he also exchanged coloured magnet which represent oxygenated and deoxygenated blood.
Earlier this year, whitish discharged was reported at Whampoa River.
There was no update about it about until today. Investigations by National Environment Agency (NEA) shows that the source of the water pollution is chemical illegally discharged by a construction firm, Singbuild. The firm was fned a total of $7,000 for illegal dumping industrial waste and debris into drains.
