RESEARCH

We are new scientists and we would like to know more about matter.We have many questions to make and solve. Our world is in danger and we must look for new solutions. Could we help our world? Could we find new answers? Go!!!!

Basic properties of matter: all matter has these!

MASS

DENSITY

VOLUME

TO FIND OUT THE DENSITY OF AN OBJECT, WE DIVIDE ITS MASS BY ITS VOLUME

THE AMOUNT OF SPACE THAT AN OBJECT OCCUPIES. WE MEASURE VOLUME IN CUBIC METRES (m3)

THE AMOUNT OF MATTER IN AN OBJECT.WE MEASURE MASS IN KILOGRAMS (KG.)

other properties of matter: depend on the material

ELECTRICAL CONDUCTIVITY

SOLUBILITY

HARDNESS

Most metals are hard materials. Sponge is a soft material

Copper is an electrical conductor, it allows electric current to flow through it. That's why leads are made of copper.

Ability to dissolve inwater. Salt and sugar are soluble and sand is insoluble.

LEAD: PLOMO

Try your luck!

2nd research: PURE SUBSTANCES AND MIXTURES

PURE SUBSTANCES

They consist of only one component. for example: gold, diamond

hETEROGENEOUS MIXTURES

MIXTURES

We can see the components very clearly. Example: pizza

They ARE THE COMBINATION OF TWO OR MORE COMPONENTS. MOST OF THE OBJECTS AROUND US ARE MIXTURES

homogeneous MIXTURES

We cannot see the components clearly. Example: strawberry smoothie

separating mixtures: different ways

magnetism

evaporation

FILTRATION

When a solution, like seawater, is heated, the water evaporates and transforms into a gas, but the solid doesn't evaporate. SOLID-LIQUID

Solids can be separated from liquids by passing the mixture through a filter. SOLID-LIQUID

To separate metal objects (iron) with magnets SOLID-SOLID

decantation

To separate liquids with different densities LIQUID-LIQUID

instrument:separating funnel

3RD RESEARCH: experiment time!

colorful tower

Materials for the group:

• Long glass container/ Frasco de vidrio trasparente (vaso de tubo, vaso largo, etc.)
• Honey/Miel
• Colored liquid soap/ Jabón líquido de color (jabón de manos, gel, jabón de lavavajillas)

• Oil/ Aceite
• Alcohol/ Alcohol
• Coloring/ Colorante de DOS colores distintos (alimenticio o no)

experiment time!

ORDER OF THE LIQUIDS:

colorful tower

TAKE OUT YOUR MATERIALS FOR THE EXPERIMENT

ALCOHOL

OIL

We pour the liquids we have selected into the container. The densest liquid is at the bottom of the glass/container, and the others are ordered from highest to lowest density. They do not mix because of the difference in their densities.

WATER

LIQUID SOAP

HONEY

homework: a lab report

SECTIONS -Materials - Directions: How did we do the experiment? -What happened?: In this case, have the liquids been mixed or not? Have new colors been created? How have the liquids been ordered?

Chemical changes

VS

Physical changes

• No new substance is produced.
• Physical changes are REVERSIBLE. We can get back the original substance after the change.

• Most importants examples:
• Changes of state
• Changes in shape (applying a force)

• A new substance is produced
• Chemical changes are IRREVERSIBLE. The new substance can’t be changed into its original form.
• Most important examples:
• Oxidation, combustion, fermentation.

4TH RESEARCH: States of matter

Matter can be in three states:

SOLID

LIQUID

GAS

physical changes in matter: CHANGES OF STATE

How does matter change from one state to another?- When we apply thermal energy (heat) -When the substance cools down, it changes back to its original state.

SOLID

GAS

LIQUID

CHEMICAL changes in matter

oxidation

fermentation

Rusty

combustion

This reaction produces light and heat in the form of fire.

oxygen + substance

In this reaction, molecules are converted into other simpler molecules.

It takes place when oxygen combines with a substance.
