Teaching physical science can be pretty tricky for the kid who asks soooo many questions. I have one of those kids. She wants to know when rainbows first came into existence and how to heck does gravity ACTUALLY work. The textbook just doesn't do it for her.
Because she is a kinesthetic and visual learner, I have to provide experiments that teach her the properties and principles of everything. I'm okay with that; it just requires more prep work than the auditory kid...or the kid (me!) who writes everything down and remembers it forever.
Currently, we are doing physical science in our first grade curriciulum. Last week, we learned about solids, liquids, and gases, and because the concepts were so simple, an experiment wasn't required...well, almost not required...we did do a Sink and Float experiment, but that was just because it's fun. Science is fun.
This week, we are talking about light. And I just know that when she wakes up, she's going to want to know how light works. What is refraction? How does light bend? How can light through water make rainbows? Oh goodness, it's going to be a long week of exploration, that's for sure.
To be on the ready, I've planned a few experiments for the week to help her understand light as best as possible at the ripe age of six. I've laid them out in question form, so you can use them based on your child's questions...hope it helps!
Why Is the Sky Blue?
What to Look For
Watch the light coming through the container from the side of the tank and then from the end of the tank. You will notice that from the side of the tank, the color is blue and the from the end of the tank, the color is more yellow.
If you are having a hard time seeing it, use the white index card and have the light shine onto that.
The colors will show so long as you've added enough milk to the water.
