Blood Moon - And P4 Science

By
Did you catch the blood moon/ blue moon/lunar eclipse on 31 Jan 2018? 


Picture from: Science centre
Were you are the science science?

I did. Accidentally. Didn't had time to watch the TV or see my social media, so I didn't know about the natural occurrence today! 

I was running with my colleague (more than colleague more than friends actually) around Novena area and we looked up at the moon and exclaimed: 

"The moon is red today! " 
Didn't bring my phone. My friend's photo. :) 








Sequence of events
At 10pm, when I was watching TV, it was all over the news. I also saw lots of FB post on it.  On the way home, I saw a crescent (moon partially blocked). I reached home about 11pm and it was a bright round 'normal' moon again! 


How did it happen?

P4 Science Question (Concept on light): 

Q: How do we see the red blood moon? 
Red light was reflected from the moon into our eyes.

Happens for a shorter time.
Can be seen only at smaller part of the world.

Happens for a longer time.
Can be seen by a bigger part of the world.



P4 Science Question (Concept on light): 

Q: Why is the moon 'black'?
Light from the sun cannot be reflected by the moon (as the Earth blocks the light from the sun) into our eyes, so the moon appeared 'black'.

Q: How are shadows (= lunar eclipse) formed? 

Light from the sun was being blocked by the Earth, forming a shadow.

Answers to PSLE Questions

Why do I write suggested solutions to Red Swastika 2018 SA1 Paper? - My students found it useful and requested for more!  - The parents who used it to help their child have found it useful!  That's why despite using 4 hours just to write ONE SET of the suggested solutions (Section B only) and doing the miscellaneous admin such as scanning, downloading documents, writing email to send out to our ISUN warriors, I do it.  Hope that all these will contribute to their learning :)  From the paper, there are quite a couple of questions from the PSLE Booklet: You can download the Red Swastika 2018 Paper here!  Red Swastika 2018 Q 30 Reproduction of Plants PSLE 2018 Q15 TEST IT OUT!  PSLE 2018 Q15 ANSWER  Red Swastika 2018 Q33 Adaptations PSLE 2013/ Specimen Paper Adaptions TEST IT OUT!  PSLE 2013/ Specimen Paper Adaptions ANSWERS Refer to other posts to learn more!

Respiration and Photosynthesis

By
Respiration and Photosynthesis With air quality going downhill, there may be chances that we need to carry plants around as our oxygen tank.  The working mechanism is based on 2 simple concepts of Primary 5 Science, Respiration and Photosynthesis.  As seen from the picture, the man is wearing a mask connected to the plant. As the man respires, it gives out carbon dioxide.  The carbon dioxide, together with water and light, the green plant with cholorphyll photosynthesises and produces oxygen for the man to respire and survive.   A summary of the both respiration and photosynthesis processes are below: Respiration Respiration is the breaking down of digested food with oxygen to produce energy. The equation of Respiration Sugar (from digested food) +  Oxygen (from inhaled air)   รจ  ENERGY (for body to use) +  Carbon Dioxide (to exhaled air) + Water Vapour (to exhaled air)  *NOTE* All living things respire includ...

3 Common Mistakes in P6 Forces

By
3 COMMON MISTAKES IN FORCES:  *Apologies that the alignment of this page is off & I can't seem to get it adjusted for now. If you want a downloadable worksheet, PM us at isuninfo@gmail.com *  1. Gravitational force (GF) vs Gravitational Potential Energy (GPE) Example 1 The ISUN warriors were playing at the corridor with a wooden ball. Xavier accidentally threw a ball and it travelled in the path as shown below rolling to a stop.   Which one of the following statements is correct? 1)       Gravity acted on the ball only when it travelled from Q to R. 2)       There are no other forces acting on the ball from P to Q except gravity. 3)       The amount gravity acting on the ball when it travelled from P to R is the same. 4)       The amount of gravity acting on the ball increased when the ball travelled from P to Q and d...
