![Page 2: Guiding Science Experiences Chapter 23. What is Science? Study of natural processes and their products. Children must explore to understand world. Children.](https://reader035.fdocuments.in/reader035/viewer/2022062423/5697bfd51a28abf838cad40b/html5/thumbnails/2.jpg)
What is Science?
Study of natural processes and their products.
Children must explore to understand world.
Children explore they activity learn. Experiences should be a hands-on
approach.

Why Study Science?
Enhance the curiosity of children Build skills in picking out
similarities and differences. Language and general knowledge
improve. Fine-motor and hand-eye
coordination improve

Planning Science Activities Some are planned and unplanned Planned experiences are bested
when focused on a theme. Science activities are best meshed
with other daily activities. Example: snacks
Give children time to play with, examine, and try science materials and equipment

Science Area Science area
usually set apart from other classroom activities
Best located near kitchen
Outdoor area can also be used. Example: weather tests garden, raising animals.

Equipment and Materials
Consider the safety of items Consider the cost of items (many
no cost items can be used) Science table can be used to
display science related items. Change material often so children
explore
![Page 9: Guiding Science Experiences Chapter 23. What is Science? Study of natural processes and their products. Children must explore to understand world. Children.](https://reader035.fdocuments.in/reader035/viewer/2022062423/5697bfd51a28abf838cad40b/html5/thumbnails/9.jpg)
Role of Teacher Offer space,
materials, and activities that encourage discovery
Constant supervision because of safety
Offer suggestions to frustrated children
![Page 10: Guiding Science Experiences Chapter 23. What is Science? Study of natural processes and their products. Children must explore to understand world. Children.](https://reader035.fdocuments.in/reader035/viewer/2022062423/5697bfd51a28abf838cad40b/html5/thumbnails/10.jpg)
Effective Questioning To encourage children to
explore, use effective questioning
Open-ended questions promote discussions
Example: How could you classify these?
Close –ended questions demand few decision-making skills (yes or no questions)
Example: what color is it?
![Page 11: Guiding Science Experiences Chapter 23. What is Science? Study of natural processes and their products. Children must explore to understand world. Children.](https://reader035.fdocuments.in/reader035/viewer/2022062423/5697bfd51a28abf838cad40b/html5/thumbnails/11.jpg)
The Five Senses to teach Science Children learn by exploring with their
senses. Below are examples to use in classroom Feelings – a feely box can be used Smelling – use items in classroom that have
an odor (play dough) Seeing – a game to play is “I Spy” Hearing – tape sounds and voices for the
class to guess what the sound is. Tasting – tasting party with food
![Page 12: Guiding Science Experiences Chapter 23. What is Science? Study of natural processes and their products. Children must explore to understand world. Children.](https://reader035.fdocuments.in/reader035/viewer/2022062423/5697bfd51a28abf838cad40b/html5/thumbnails/12.jpg)
Using Color to Teach Science Children observe color daily Color serves as a basis for groupings
Example: have children match blue toys Some teachers have special color days
Example: Monday is orange day Teach color concepts by mixing colors
Mix primary colors to make secondary colors
![Page 13: Guiding Science Experiences Chapter 23. What is Science? Study of natural processes and their products. Children must explore to understand world. Children.](https://reader035.fdocuments.in/reader035/viewer/2022062423/5697bfd51a28abf838cad40b/html5/thumbnails/13.jpg)
Using Water to Teach Science Water delights almost all children If there is no water table use sink or
plastic swimming pools Fill the water based on children's
experience and age Example: young children need 2 or 3 inches
of water Water can teach children about
materials absorb water, floating, what materials dissolve in water, painting with water.
![Page 14: Guiding Science Experiences Chapter 23. What is Science? Study of natural processes and their products. Children must explore to understand world. Children.](https://reader035.fdocuments.in/reader035/viewer/2022062423/5697bfd51a28abf838cad40b/html5/thumbnails/14.jpg)
Using Food to Teach Science By watching foods cook, children learn
how solid materials change (texture and color change)
Baking bread involves both process (reading recipe, collecting ingredients) and product
Cooking projects can be tied to a theme or unit
Children learn food varies in size, shape, and color.
![Page 15: Guiding Science Experiences Chapter 23. What is Science? Study of natural processes and their products. Children must explore to understand world. Children.](https://reader035.fdocuments.in/reader035/viewer/2022062423/5697bfd51a28abf838cad40b/html5/thumbnails/15.jpg)
Using Child’s Body to Teach Science
Children can understand how their own body is changing through science
One science concept is that people can be recognized by the way they look.
Another science concept is measurements: Growth or weight charts can be used
![Page 16: Guiding Science Experiences Chapter 23. What is Science? Study of natural processes and their products. Children must explore to understand world. Children.](https://reader035.fdocuments.in/reader035/viewer/2022062423/5697bfd51a28abf838cad40b/html5/thumbnails/16.jpg)
Using Gardening to Teach Science Learning about gardening and seeds
helps children build an interest in growing things.
Science experiments using seeds can be introduced during snack or lunchtime.
Observe seeds with a nature or seed walk
Planting seeds indoor and outdoors teachers children growth
![Page 17: Guiding Science Experiences Chapter 23. What is Science? Study of natural processes and their products. Children must explore to understand world. Children.](https://reader035.fdocuments.in/reader035/viewer/2022062423/5697bfd51a28abf838cad40b/html5/thumbnails/17.jpg)
Using Air to Teach Science Teaching about air
Example: inflate some balloons to help children understand air takes up space
Teaching about wind Use thin strips of newsprint streamers to
teach the concept that wind makes things move.
Using weather When creating activities relating to weather
(snow, wind, rain) make it appealing to young children.
![Page 18: Guiding Science Experiences Chapter 23. What is Science? Study of natural processes and their products. Children must explore to understand world. Children.](https://reader035.fdocuments.in/reader035/viewer/2022062423/5697bfd51a28abf838cad40b/html5/thumbnails/18.jpg)
Using Magnets to Teach Science Magnet concepts are best learned
through a combination of teacher guidance and hands-on activates.
Buy magnets in a variety of shapes As children play with magnets they will
observe things about them. Activity: have children pick up various
objects with magnets. Children will learn magnets pull some
things, but not others

Using Wheels to Teach Science
Children see wheels every day Example: car, truck, bus
Expose children to many times of wheels. Example: lawnmower & vacuum
cleaner Example activity: cut out and hang
pictures of wheels from magazine
![Page 20: Guiding Science Experiences Chapter 23. What is Science? Study of natural processes and their products. Children must explore to understand world. Children.](https://reader035.fdocuments.in/reader035/viewer/2022062423/5697bfd51a28abf838cad40b/html5/thumbnails/20.jpg)
Using Field Trips and Walks They promote curiosity, supply
opportunities for discovery, and encourage interaction with the environment
Children can observe how machines make work more precise, easy and orderly. Example, trip to fire station, point out
fire alarm, ladder, and hose.
![Page 21: Guiding Science Experiences Chapter 23. What is Science? Study of natural processes and their products. Children must explore to understand world. Children.](https://reader035.fdocuments.in/reader035/viewer/2022062423/5697bfd51a28abf838cad40b/html5/thumbnails/21.jpg)
Using Animals to Teach Science
Children can learn: Care of animal (all animals must
receive humane care & treatment) Value of animal (there are many
values animals have for children) Animals as classroom pets (hamsters,
snakes, toads & frogs, fish, rabbits, and guinea pigs)
![Page 22: Guiding Science Experiences Chapter 23. What is Science? Study of natural processes and their products. Children must explore to understand world. Children.](https://reader035.fdocuments.in/reader035/viewer/2022062423/5697bfd51a28abf838cad40b/html5/thumbnails/22.jpg)
Care of the Earth Children should
learn to preserve earth by keeping it clean
Set the stage for recycling in classroom Label bins paper,
glass, metal, and plastic
