Hello everyone! For the past few weeks we did our soundtrack of our lives in English in which we need to introduce oursleves or a little about us. After that, we are then to choose five of our favorite songs that is very special to us, why is it important to us, and why did we chose those songs. Out of all the five songs, we only need to choose one song to present infront of our class and talk about why we chose that and why is it so special to us.

The song I’ve chosen for this presentation is the song ‘Pasilyo’ can be translated to english as ‘aisle’. As a Filipino this song will always be my favorite song.

What is Pasilyo all about?

– The song “Pasilyo” is all about marriage.
The lyrics behind this song explains and describes how the protagonist is deeply in love with their partner and feels joy, love, and thought of being with them forever. They imagine walking slowly towards the altar in a church to get married, and they can’t imagine needing anything else in life. They pray to God that they can spend their life living together until their old age, and even dreaming of taking their partner’s last name. Throughout the song, the protagonist emphasizes that their partner is the only one for them and that they love them truly and deeply.

Thak you for readng my blog post have a nice day!

Hello everyone,

Today we learned about mutations and selections for Science. We learned about what they meant and what they were.

There are three main types of mutations:

Substitution – A base is substituted/swapped for a different base.

Deletion – A base is deleted/removed.

Insertion – A base is added.

Mutations

Mutations, and alterations within DNA, lead to the creation of alleles. UV light, chemicals, dietary habits, and radiation exposure can induce mutations.

Thank you for reading my blog, I hope you have a fantastic day!

Aim: To observe conduction on a metal rod.

Equipment: Metal bar, tripod, bunsen burner, petrolium jelly, six drawing pins, a stopwatch.

Thermal conducters are all materials that heat up.

An example of conducters are metal, copper, steel.

As a science enthusiast, one of my favourite experiments to conduct is the Dropping Pins experiment. It’s simple to perform, requires minimal equipment, and provides a great opportunity to learn about gravity and the laws of motion. In this blog post, I’ll be sharing with you the equipment you need and the steps to perform this fun experiment.

Equipment:

– A ruler

– Bunsen burner

– Several pins

– Stopwatch or timer

conductors – Metals such as

copper, aluminium, iron, and silver

– Non-metals such as graphite and silicon carbide

– Carbon steel

– Brass

– Bronze

– Gold

– Silver

– Platinum

– Nickel

– Titanium

– Tungsten

– Zinc

– Mercury

– Sodium

– Potassium

– Water

– Glass

– Concrete

– Stone

Here is a list of non-conductors or poor conductors of heat:

– Wood

– Plastic

– Rubber

– Glass

– Air

– Styrofoam

– Paper

– Cloth/Fabric

– Wax

– Cork

– Insulating materials like fibreglass and mineral wool

Keep in mind that some materials may conduct heat to some extent, but are still considered poor conductors compared to metals, which are excellent conductors of heat.

Keep in mind that the degree of conductivity varies for each material, and some materials may have better heat conductivity than others.

Steps:

1. Begin by setting up the experiment area. Find a flat surface to perform the experiment on, and make sure there is adequate space to drop the pins.

2. Next, measure the height of the Bunsen burner you will be using to drop the pins. Use the ruler to measure the height in centimetres and record the measurement.

3. Take one of the pins and hold it at the top of the Bunsen burner. Make sure the pin is held perpendicular to the surface and is not at an angle.

4. Release the pin and start the stopwatch or timer as soon as it is dropped. Stop the stopwatch or timer as soon as the pin hits the surface.

5. Record the time it took for the pin to fall to the surface in seconds.

6. Repeat steps 3-5 several times, using different pins each time. Make sure to record the time it takes for each pin to fall to the surface.

7. Once you have recorded the times for each pin, calculate the average time it took for the pins to fall to the surface.

8. Using the height of the Bunsen burner and the average time it took for the pins to fall, calculate the acceleration due to gravity using the following formula: Acceleration due to gravity (g) = 2h/t^2. Here, h is the height of the Bunsen burner and t is the average time it took for the pins to fall.

In conclusion, the Dropping Pins experiment is a great way to learn about gravity and the laws of motion. By measuring the time it takes for pins to fall from a certain height, we can calculate the acceleration due to gravity. This experiment is simple to perform and only requires a few basic materials. So, what are you waiting for? Grab some pins, a ruler, and a Bunsen burner and try it out for yourself!
