And some materials do not.

 

Water and oil don´t mix well.

• We can separate some mixtures:

We can separate rice and water by sieving.

I can heat an egg.


I can melt and ice cube.

UNIT 4: THE PLANT KINGDOM

Algunas mamás me habían pedido algunos consejos sobre cómo preparar los exámenes de Science, aquí os dejo algunas sugerencias que espero sean de ayuda.

¿Cómo preparo mi examen de Science?

-Repaso cada día lo que se da en clase.

-Practico en casa escribiendo varias veces las palabras en inglés.

-Puedo practicar haciendo ejercicios de unir con flechas, completar con la palabra que falte...

Por ejemplo:____________ absorb sunlight. -> Leaves absorb sunlight.

-Del libro hay que estudiar los cuadritos que vienen en cada página y los ejercicios que suelen ser muy similares a los del examen. En algunos temas también copiamos alguna cosita en el cuaderno, que también nos sirve para estudiar en casa.

-Antes del examen suelen llevar una ficha de repaso, también nos puede servir para repasar en casa.

-En el  resumen del blog de cada tema viene todo lo entra para el examen.

-Puedo traducir algunas palabras de las que no conozca el significado pero el examen es en inglés, por lo que hay que conocerlas en inglés.

Aquí tenéis un resumen del tema para repasar un poquito:

PLANTS ARE LIVING THINGS (PAG 55)
*Tenéis que saber escribir solos las partes de la planta y su ciclo de vida.

Plants are living things and they need air, water and sunlight to grow.




Lifecycle (CICLO DE VIDA)

ROOTS take up water.
 ROOTS

LEAVES absorb sunlight.
LEAVES

FLOWERS produce seeds.
 FLOWER


Plants grow, reproduce and die.





TREES, BUSHES AND GRASSES (PAG 56)
*Tenéis que estudiar los nombres y sus características.

Trees have a thick, hard stem called  a trunk. (Los árboles tienen un grueso y duro tallo llamado tronco)
TREE

Bushes have lots of woody stems.
(Los arbustos tienen muchos tallos leñosos)

BUSHES


Grass is thin and bendy.
(La hierba es delgada y flexible)

GRASS

WILD OR CULTIVATED? (PAG 57)
*Tenéis que saber diferenciar entre plantas cultivadas y salvajes.

Cultivated plants grow in pots, garden and fields.
People look after them.

CULTIVATED PLANTS
 
Cutivated plants grow in:

 POTS
 GARDENS
 FIELDS


Wild plants grow naturally.
WILD PLANTS


WE USE PLANTS IN DIFFERENT WAYS (PAG 58)
*Conocer los diferentes usos de las plantas en inglés.

We use plants.

  COTTON (ALGODÓN)-> CLOTHES (ROPA)

 WHEAT (TRIGO)-> BREAD (PAN)

 ALOE VERA-> SUN CREAM (CREMA SOLAR)

  PINE TREE (PINO) -> TABLE (MESA)

WE EAT DIFFERENT PARTS OF PLANTS (PAG 59)

We eat roots, steams, leaves and fruit of some plants.

 TOMATO-> FRUIT (del tomate nos comemos el fruto)

LETTUCE-> LEAVES

POTATO-> ROOTS
LEEK-> STEMS (TALLO)

UNIT 2

En esta unidad estamos copiando algo de teoría en el cuaderno para estudiar en casa junto con lo que viene en el libro. Sería recomendable repasar cada día lo que se da en clase para que cuando llegue el examen no sea tanta materia. Les recuerdo en clase a diario que el cuaderno y el libro debe ir a diario a casa para repasar, recordadlo en casa también para que no se les olvide.

Estamos aprendiendo lo siguiente:

- Helmet (casco) protects your head (cabeza).

- Skull (cráneo) protects your brain (cerebro).

-Ribs (costillas) protect your heart (corazón).

- Knee pads (rodilleras) protect your knees (rodillas).
-Gloves (guantes) protect your hands (manos).

A BALANCED DIET  (UNA DIETA EQUILIBRADA)

Tengo que saber cuales son los "FOOD GROUPS" y que tipo de alimento va en cada grupo.

Food Groups:

1. Carbohydrates: bread, potatoes, pasta...

2. Fats: butter, olive oil, sunflower oil...

3. Proteins: fish, eggs, meat...

4. Dairy products: milk, yoghurt, cheese...

5. Fuits and vegetables: carrots, peppers, spinach, tomatoes, grapes, pear, green beans...

MEALS

Tenemos tres comidas principales al día:

1.Breakfast: desayuno

2. Lunch: almuerzo

3. Dinner: cena

Si tenemos hambre entre comidas podemos tomar uno o dos SNACKS, pero recuerda que sean HEALTHY SNAKS (snacks saludables): apple, banana, juice...

Aquí os dejo algunos juegos para practicar el vocabulario y los conceptos de esta unidad. Haz click en estos enlaces para jugar:
