Bend a Straw with Your Eyes

Using the power of your eyes, bend a straw sitting in half a glass of water without even touching it! It sounds like magic but it's really another amazing scientific principle at work.

What you'll need:

A glass half filled with water

A straw

2 eyes (preferably yours)

Instructions:

1. Look at the straw from the top and bottom of the glass.

2. Look at the straw from the side of the glass, focus on the point where the straw enters the water, what is strange about what you see?

What's happening?
Our eyes are using light to see various objects all the time, but when this light travels through different mediums (such as water & air) it changes direction slightly. Light refracts (or bends) when it passes from water to air. The straw looks bent because you are seeing the bottom part through the water and air but the top part through the air only. Air has a refractive index of around 1.0003 while water has a refractive index of about 1.33.

Make Your Own Rainbow

Learn how to make a rainbow with this fun science experiment for kids. Using just a few simple everyday items you can find out how rainbows work while enjoying an interactive, hands on activity that's perfect for kids.

What you'll need:

A glass of water (about three quarters full)

White paper

A sunny day

Instructions:

1. Take the glass of water and paper to a part of the room with sunlight (near a window is good).

2. Hold the glass of water (being careful not to spill it) above the paper and watch as sunlight passes through the glass of water, refracts (bends) and forms a rainbow of colors on your sheet of paper.

3. Try holding the glass of water at different heights and angles to see if it has a different effect.

What's happening?
While you normally see a rainbow as an arc of color in the sky, they can also form in other situations. You may have seen a rainbow in a water fountain or in the mist of a waterfall and you can even make your own such as you did in this experiment.

Rainbows form in the sky when sunlight refracts (bends) as it passes through raindrops, it acts in the same way when it passes through your glass of water. The sunlight refracts, separating it into the colors red, orange, yellow, green, blue, indigo and violet.

Color, light and absorbing heat - Fun Science Experiments for Kids

# data[].attributes.attachment_link.description
Dark surfaces such as the black paper absorb more light and heat than the lighter ones such as the white paper. After measuring the temperatures of the water, the glass with the black paper around it should be hotter than the other.

Sun, Light & Shadows

Learn about the sun, light & shadows as you experiment with different light sources and objects in this fun, interactive science activity for kids. Moving a light source closer to an object can make its shadow grow larger while moving the light source away can have the opposite effect. Experiment and see what happens to the shadows of different objects when you tilt the light source or change its brightness, what happens to the shadow if the light source is dim? Head outside and see how sunlight creates shadows with various objects such as trees, houses and cars. Learn how the sun's position in the sky effects the size of shadows. Even the moon can create shadows when it reflects light from the sun. Enjoy the challenge of this cool science game.

How We See

Eyes are amazing parts of the human body, learn how we see as you experiment with light & mirrors in this fun science game for kids. Change the mirror angles to see which way they reflect the light. Practice hard and see if you can get the mirrors at the right angles so that the light reflects onto the tent. Once you've achieved that goal use what you've learned to try and illuminate other objects by controlling the path of the light. Kids will love the challenge of this cool, interactive activity.
