Chemistry
What is a spectroscope?
A spectroscope is a tool that helps us see the different wavelengths of light from a star or another light source.
What are glow sticks?
Glow sticks are small plastic tubes that can produce light without using electricity, heat or batteries.
What happens when the light hits an objects?
When the light hits an object, light can reflect, refract, or be absorbed.
What is a prediction?
A prediction is not just a guess it is based on what we already know.
What is the temperature of our star?
The surface temperature of our star, the Sun, is approximately 5,500 °C
How a spectroscope work?
Light is split into different colors by the prism inside the spectroscope.
How can a glow sticks produce light?
A glow stick produces light through chemiluminescence, a chemical reaction that emits light without heat.
What type energy is the light?
Light is a type of energy that helps us see.
What are a dependent variable?
Dependent variables are the result you measure after you make a change.
where is a radiation zone?
Where temperatures in our star range from about 7 million to 2 million degrees.
How can a spectroscope tell us what stars are made of?
A spectroscope helps scientists discover what elements(like hydrogen, helium, and oxygen) are in a star.
How does temperature affect a glow stick?
Temperature influences the rate of the chemical reaction inside a glow stick. Heat increases the reaction, producing a very intense but brief glow.
When does light reflect?
Reflection happens when light bounces off a surface.
What is a controlled variable?
Controlled variables are things you keep the same during the experiments.
what happens when you bend a glow sticks?
when you bend a glow sticks the glass tube inside breaks. This allows the two chemicals to mix together.
What type of objects reflect the light?
he objects on which light is reflected are made of smooth, shiny or polished materials such as mirrors, metals, water and glass.
What is the science experiment?
Science experiments help us ask question and find a answer about the world around us.
How many chemicals are in a glow stick?
Inside a glow stick are two different chemicals. One chemical is inside a small glass tube, and the other chemical is in the outer plastic tube.
What is a prism?
Prism is a clear glass object that shows refraction.
What is a independents variable?
Independent variables are what you change in an experiment.
