UP2B

Research method. Chemical laboratory


Rīgas Pārdaugavas pamatskola

Participants:

Olga Gubkina - teacher testing the methodology.

3C class students

   

Activity title:

Research method. Chemical laboratory

Group size:

1-2 groups of 10 -30 students

 

Group age:

In native language the age is 8-10years,

If we speak about learning topic Jobs in foreign languages-the age is 8-13 years old

 

Activity duration:

20

 

Overview and objectives:

This knowledge will help us! I want and can, studying chemistry and natural history, be a drug maker, a doctor, a nurse, a technologist in a cafe, a cosmetologist, a hairdresser, a creator of paints for decorating houses.
We form children's elementary ideas about the properties of water: "push" air to the surface.
We develop scientific thinking: we conduct classes through research; through mistakes we learn to analyze.
We promote the interaction of independence and activity, motivate interaction with classmates and adults.

 

Materials/equipment needed:

3 copies of the list of professions

 

Preparation:

Worksheets, book - algorithm, water, aquarium, balls, water, magnifying glass.

 

Tips/comments/recommendations:

 

This knowledge will help us! I want and can, studying chemistry and natural history, be a drug maker, a doctor, a nurse, a technologist in a cafe, a cosmetologist, a hairdresser, a creator of paints for decorating houses.

Detailed instructions:

We treat you to an orange, but it must be peeled.
Oh, bad luck, the orange falls into the aquarium. Plunging to the bottom of the tank, he lies quietly.
Weird! After all, when mom sows oranges, they pop up.
What is the secret?
The secret is in the orange peel. Examining the peel through a magnifying glass, we noticed air bubbles. It is the air in the peel that prevents the orange from sinking into the water.
Air is lighter than water, which pushes the air to the surface, so the peeled orange floats on the surface of the water.
The main thing! So that future chemists, technologists, pharmacologists understand or guess about the reasons.
If you take a balloon and inflate it, you will get an air bubble.
We are all together trying to sink the ball to the bottom of the aquarium.
We, like people who lived centuries ago, noticed this property of water and air - to push air to the surface!

This knowledge will help us! I want and can, studying chemistry and natural history, be a drug maker, a doctor, a nurse, a technologist in a cafe, a cosmetologist, a hairdresser, a creator of paints for decorating houses.
All listed?
Probably not, but we still have time to think.
After the 9th grade, you can enter Olaine College, which trains technologists for the food industry.
You can enter after the 12th grade at the Riga Technical University, Medical University. Stradin
a, at the Faculty of Chemistry of the University of Latvia.
Or maybe we will also set off in another professional direction!?

Why don't oranges sink in water?

One of the most common directions in Latvia is chemical-technological and pharmaceutical.

I would go to chemists, let them teach me!

Cognitive research activity begins in early childhood. It is at this age that a child can exclaim: "Eureka!".

The task is simple.

• We form children's elementary ideas about the properties of water: "push" the air to the surface.

• We develop scientific thinking: we draw conclusions through research; through mistakes we learn to analyze.

• We help to show independence and activity, motivate to interact with classmates and adults.

Water dissolves, pushes out, does not connect.

We have yet to discover! But for now, we will analyze what was discovered before us.

So!
