STEPS TO SOLVE A SCIENTIFIC  EXERCISE

(Natural Sciences: PHYSICS) 2º ESO

  1.  Read the problem carefully
  2.  Write the formula that you need.
  3.  Use the data that you know.
  4.  Calculate.
  5.  Write the result with the correct units.

Last september I started teaching the level 2º ESO in the bilingual programme for my first time. Sincerously, me (as the kids) I also prefer animals and plants to physics, but we must start the school year speaking about density, matter, energy, and stuff like that. Anyway, it happened to me that as introducing the topic of “Mass Vs Weight all my students turned excited and started to mumble a strange song. Thanks to their last year´s great teacher (my colleague Julia Ara) they had very well learned the differences between mass and weight with a song from youtube while having fun.

With this post I want to thank Mr Edmonds´ work and share with you these  great science song parodies available on his  youtube channel:  .

Don´t miss it.

And now, Mr Edmonds´Hit Parade: Mass versus Weight

Lyrics:

Mass versus weight — two measures for an object.
They’re not the same, let’s all see why!
To determine the mass, we use a balance to do it.
We use a scale to measure weight.

Mass, measured in grams, or in kilograms,
It’s all about how much stuff – the object has!

Grams or kilograms (ba! ba! ba!)
They’re the units we use for mass. (for mass, for mass, for mass).
Newtons are for weight (ba! ba! ba!)
Weight’s the measure of gravity’s pull on the ob-ject.

So you can see, mass and weight aren’t the same thing.
Weight is the measure of gravity’s pull!
In contrast to weight, mass tells us how much matter,
How much matter the object has.

Mass, measured in grams, or in kilograms,
It’s all about how much stuff – the object has!

Grams or kilograms (ba! ba! ba!)
They’re the units we use for mass. (for mass, for mass, for mass).
Newtons are for weight (ba! ba! ba!)
Weight’s the measure of gravity’s pull on the ob-ject.

Mass and weight, mass and weight, they’re not the same.
Mass and weight, mass and weight, they’re not the same.
Mass and weight, they’re not the, not the same.

Grams or kilograms (ba! ba! ba!)
They’re the units we use for mass. (for mass, for mass, for mass).
Newtons are for weight (ba! ba! ba!)
Weight’s the measure of gravity’s pull on the ob-ject.
Yeah!

“Eureka! is a series of humorous, and information-packed programs that bring “boring” physics concepts to vibrant, vigorous life.”

I want to remark this Eureka! TV Series where you can find very good didactic videos to explain physics concepts such as the forms of Energy, mass, weight, inertia, heat, etc. (you can watch them at  the EurekaTutoring’s channel)

Give a look for example at his one explaining Potential Energy with some references to Kinetic Energy too.

I present this classification with some of the most remarkable videos to be watched in 2º ESO, Natural Science ordered according to our program:

Matter

Eureka! Episode 1 Inertia

Eureka! Episode 2 Mass

Eureka! Episode 6 Gravity

Eureka! Episode 7 Weight vs Mass

Eureka! Episode 25 – Volume & Density.flv

Eureka! Episode 23 – Electrons.flv

Eureka! Episode 22 – Atoms.flv

Energy

Eureka! Episode 9 Kinetic Energy

Eureka! Episode 10 Potential Energy

Eureka! Episode 8 Work

Heat

Eureka! Episode 28 – Heat as Energy.flv

Eureka! Episode 21 – Temperature vs. Heat.flv

Eureka! Episode 16 Molecules in Solids

Eureka! Episode 17 Molecules in Liquid

Eureka! Episode 18 Evaporation and Condensation

Eureka! Episode 19 – Expansion and Contraction.flv

Eureka! Episode 20 – Measuring Temperature.flv

Eureka! Episode 26 – Buoyancy.flv

Eureka! Episode 24 – Conduction.flv

Eureka! Episode 27 – Convection.flv

Eureka! Episode 29 – Radiation Waves

Light

Eureka! Episode 30 – Radiation Spectrum

There is a total of 30 episodes and none of them lasts more than 5 minutes, ther were made in 1980, but physics have not changed so much at this level so far.

You can find the whole chapters list at  http://www.rickstv.com/tvo/eureka.html
