MOTION

In the physics activity, we determined the material of a coin (peseta) by measuring its mass and volume and calculating its density. We then compared the calculated density with known densities of materials to identify the coin's composition.

PROCESS

In this motion experiment, we calculated the average walking speed of four individuals. Each participant was recorded while walking, allowing us to analyze how time and distance are related to speed.

MEASURING A FORCE

In the physics activity, we worked on force measurement using Hooke's law, which describes the relationship between the force applied to a spring and its deformation.

To measure this force, we performed an experiment based on this law.

BUT, FIRST...

WHAT IS FORCE?

Heat

MEASURING TEMPERATURE

In this physics class, we participated in two key activities related to temperature measurement and thermometer calibration. We began by exploring the concept of heat, which is the transfer of thermal energy between objects or systems due to temperature differences. This form of energy can be transformed into other forms, such as mechanical work, and is intrinsically linked to the motion and kinetic energy of particles in a substance.

Measuring Waves

In physics class recently, we worked on wave measurement, specifically focusing on the reflection and refraction of light. We used various equipment and materials to conduct experiments that allowed us to better understand these phenomena.

Electricity

Electricity, as a fundamental branch of physics, encompasses the study of electric charge, current and their associated phenomena, focusing on the movement and interaction of charged particles in conductive materials and electrical circuits. In our activities, we explore electrostatic phenomena by transferring charge between objects such as an ebonite rod and an electrostatic pendulum, as well as evaluating conductive and insulating materials by connecting electrodes and observing their ability to light a lamp. In addition, we experimented with measuring voltages and currents in simple circuits, establishing the relationship between them using Ohm's law and exploring series and parallel circuit configurations to understand their effects on lamp brightness.

Arduino

In physics class we worked with Arduino, a microcontroller that connects to a computer and allows us to acquire data and program simple circuits. We performed two main activities:Activity #1: Setting up simple electrical circuits with Arduino, such as a circuit with a switch, a resistor and an LED, and series and parallel circuits with two switches and an LED. Activity #2: Programming with Arduino, where we created a control panel with a switch and lights that turn on when the switch is pressed. It was implemented by connecting LEDs and a switch to Arduino, and a program was written that controlled the lights turning on and off based on the signal from the switch. In addition, we learned about programming in Arduino, using functions such as setup() and loop(), and understood the use of digital pins to read voltage states (HIGH or LOW) and control the turning on and off of LED lights.

Pressure Matters

Atmospheric pressure influences heat transfer by affecting the boiling and melting points of substances. At higher pressures, such as at sea level, more energy is needed to boil water, while at higher altitudes, where the pressure is lower, water boils at a lower temperature. This relationship between pressure and phase change points is fundamental to understanding how heat is distributed and transferred in different environments and everyday situations.

LET'S SEE THE RESULTS

The Experiments:

We pointed the laser through water and observed how the light bent as it passed from one medium to another. We changed the angle of the laser to see how this affected the path of the light. We also recalled reflection using a mirror and a beam of light, confirming the law of reflection by measuring the angles of incidence and reflection. It was a hands-on class where we explored how light behaves as it passes through different materials such as water and a mirror.
