SUMMER SCIENCE ACTIVITES-EXPLORING WATER (H20)
In early childhood (age 2.5-6 years of age) an introduction to scientific concepts and terms will create an early foundation for children to understand and to love science. Science happens all around us on a daily basis. When science is introduced in school it can be overwhelming to some students. By making the term science a household word, it will help children explore and discover science and support future learning.
INDRODUCTION OF WATER
Science in the summer is a great time to explore water activities in the backyard.
Introduce the many characteristics of water and how it is used.
“Can you tell me what you know about water?”
“We drink water.”
“Water comes out of the tap.”
Introduce your child to the characteristics of water:
“Water can be in the form of a liquid, a solid or a gas.“
“The human body is made up of mostly water.”
“We need to drink water to survive.”
“We need to take care of our water sources. “
“Canada has one of the greatest fresh water sources in the world called the Great Lakes.”
INTRODUCTION TO SCIENCE:
1.) Introduce scientific terms, “In science we make a guess before we do an experiment, a guess in science is called a hypothesis.”
2.) Write down child’s hypothesis a piece of paper or a science book-if he/she wants to write it down can take the time to incorporate writing (do not worry about the response they do not need to guess the right answer. After each experiment, ask your child, “What happened?”
3.) It is not necessary to make the correct hypothesis-you can pretend like this is new for you too and the results can be discussed at the end of each experiment.
4.) The experiments do not need to be done all at once and they can be done over a few days.
Materials for all experiments:
Sugar/powdered fruit drink
Juice (Can try juice too)
Ice cube tray
What dissolves in water?
Some particles do not mix together and some things do dissolve in water,
“What do you think will happen when we mix sugar and water?”
“What do you think will happen when we mix oil and water?”
Use a small pitcher and let the child fill two containers (measuring cups or glasses that are the same size) with water.
Measure a tablespoon of sugar and pour into the water and have your child mix.
Put a tablespoon of oil in the other container of water and have your child mix.
Ask the question, “What is happening?”
Experiment #2-Liquid changes to a Solid
What happens when water is put in the freezer?
Have your child mix the water with fruit juice or a powdered drink mix and pour into ice cube trays or into Popsicle tray.
(Might be a great idea to make a set the night before on your own and this way you can bring them out to show the child and they can have one.)
“What do you think is going to happen?” “What is your hypothesis?”
Explain that when water is frozen it changes from a liquid form to a solid form.
Experiment #3-Solid changes to a Liquid
What happens when ice is put in the sun?
“What do you think will happen to the ice cube when we put it outside in the summer?” Put ice cubes outside.
Experiment #4-Liquid changes to a Gas
What happens when we boil water?
“What do you think will happen when we boil water?” Put water in a kettle and let it boil out, tip the kettle over and explain that water evaporates into the air when heated and it turns into a gas. Turn the kettle over and demonstrate that the kettle is empty. “Where do you think the water went?” HAVE FUN!
Discuss the results of each experiment.
