Water Cycle: Formation of Clouds

By

Water Cycle: Formation of Cloud @ Cradle Mountain

Common Primary 5 Science Question

Lee Xian sets up an experiment as shown below. She heated some stones to 150°C and placed them in the glass bottle as shown in the set up below.
After several minutes, she observed water droplets formed on the inside surface of the glass bottle.

(a) Explain how are water droplets formed. (2m)
The tap water gains heat from the stones and evaporates to become warmer water vapour which loses heat and condenses onto cooler inner surface of the bottle, forming water droplets.

(b) What would Lee Xian observe if she changed the hot stones to ice cubes? Explain why. (2m)
She would still observe water droplets but at the outer surface of the bottle.
The warmer water vapour in the air lost heat and condensed onto cooler outer surface of the bottle, forming water droplets.

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...
