Cornstarch experiment

OBSERVATION: Cornstarch experiment

1. Year level

- This experiment is suitable for students of third grade (8- 9 years old).

2. Objectives from the Spanish Science Curriculum

- Introduction to the development of scientific strategies , such as the ability to perform activities , observe, collect and organize relevant information , organize and analyze results , draw conclusions and communicate , work cooperatively and using form method appropriate materials and tools.

- Study and classification of some materials because of their properties.

- Predicting changes in the movement or the shape of the bodies as a result of the forces.

- Observe the properties of solids, liquids and gases.

3. 4C’s of CLIL

 Content: Understand what is a Non- Newtonian fluid and know the reaction of a Non- Newtonian fluid when we apply different forces.

CONTENTS FROM THE SPANISH SCIENCE CURRICULUM

Matter and Energy. Technology, objects and machines.

Matter states: Observe the proprieties of the solids, liquids and gas.

Changes in the movement of the bodies by force effect: Performs simple experiments to predict changes in motion, in the form or state of the body as a result of forces.

 Communication: improvement of communicative skills, cooperation between all the students

 Cognition

LOTS: making simple experiments in class and evaluating the result of the observation experiment.

HOTS: understanding the concept of Non-Newtonian fluid and observing

that it depends of the quantity of force we apply, the cornstarch acts

differently.

 Culture: Recognition of other Non- Newtonian fluids that they use at home.

4. Background information about the topic

Before to do the experiment our students must understand how matter takes different

states.

The Earth and everything on it are made of matter. Matter is anything with mass and

volume; it takes space. There are three states of matter – solid, liquid and gas.

- A solid has a certain size and shape.

- A liquid has a size or volume, but it doesn't have a definite shape. It takes the

shape of its container.

- A gas is matter that has no shape or size of its own.

Matter can change from these states by heating up or cooling down.

5. Concepts we are targeting

In the 1700s, Isaac Newton identified the properties of an

ideal liquid. Newton stated that fluids have a constant

viscosity if the temperature is kept constant. Applying a

force to the fluid doesn’t change its viscosity. This kind of

fluids like the water are call Newtonian fluids. But there

are another fluids
