1. Varo-What do you think will happen if there is no light at all? (perspective)
Answer : If there is no light we can't see anything. Light helps us to see everything. There is nothing that we can't see without light.  Activity:
1. Put yourself in a dark room with obstacles.
2. Try to find your way around the obstacles.

2.  Ibu Primi - How can light and sound save us from dangers? [reflection, function]
Answer : Light and Sound can save us from dangers because:
1. Light helps us to see things.
2. Sound helps us to hear things.
3. Sound makes us hear thing 's like fire alarms, ambulance, and police.
4. Light makes us to see trees falling and ETC

3. {Jasmine} How come light comes into different waves? - ( Form )
Answer:   Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM - you have light. Unlike many other waves (sound, water waves, waves in a football stadium), light does not need a medium to “wave” in.

Question #2 : Which ears can damage easily? - Aninda

Question #3 : Why do we need to protect our ears? - Katie
Answer #3 : Its because if we don't then soon later your ear might be deaf so its really important to protect our ears so we can hear better and it also might be also good to do an hearing test so we can check our hearing and we know if or hearing is okay or not.

Humans and animals have similar colorblindness. Allthough some animals have full colorblindness in birth. Bulls have full colorblindness at birth. So there are some differences in colorblindness between animals and humans depending in the animal type.  Some animals can't see colors because of the differences in their optical genetics.

Sound travels slowest through air because molecules that create air are far apart. Because they are far, the molecules take a longer time to collide with each other and the collision between molecules is what makes sound. Solids have molecules that are very close to each other so they transmit sound very fast. Liquids have molecules that are further apart than solids but closer to each other than gases.

Q=How is the speed of sound 767 mph?
The speed of sound varies depending on the temperature of the air through which the sound moves.On Earth the speed of sound at sea is  761.2 mph.  Because gas molecules move more slowly at colder temperatures.

Scientists are interested in the speed of sound, according to NASA, because it indicates the speed of molecules  transmitting a "small disturbance" (another way of describing a sound wave) through a gas medium.Transmission disturbance happens when a molecule in gas hit each other.

2. I will answer question from Katie about "Are our ears sensitive?" (form)
Our ears are fragile and sensitive. They can get damaged by hearing loud noises. Ears can get damaged over time if they hear noises that are 85 dB (decibels) or more. If you hear sound at 85 dB for 8 hours, your ear can get damaged. But, if you hear 115 dB, it only takes about 30 seconds until the ear gets damaged. Your ears get damaged because sound gets delivered to hair cells. Those hair cells have stereocilia. The stereocilia rocks back and forth when exposed to sound. If you hear noises that are too loud, they make the stereocilia bend/break which makes them die and never grow back again.

3. I will answer question from Ibu Primi about "What is the function of light in our daily life?" [function]
The function of light is to see. We see because light bounces off an object and we can see the light that bounces off the object. We can't see the light that the object absorbs. Example: We see an apple. It is red not because the apple is red, but because the light that bounces off it is red. If there is no light, we wouldn't be able to see anything.

4. I will answer question from Katie about "Why do we need to protect our ears?"(responsibility)
We need to protect our ears because if you get hearing loss, you will never get your hearing back. We hear because sound waves go into your ear canal as vibrations until they reach the eardrum. The eardrum passes the​ vibrations through the middle ear bones (ossicles) into the cochlea. Inside the cochlea, there are​ thousands of tiny hair cells. Hair cells change the vibrations into electrical signals that are sent to​ the brain through the hearing nerve. The brain tells you that you are hearing a sound and what that​ sound is.​ Each hair cell has a small patch of stereocilia. The stereocilia rocks back and forth when exposed to sound. If you hear noises that are too loud, they make the stereocilia bend/break which makes them die and never grow back again.

An ear infection occurs when a bacterial or viral infection affects the middle ear — the sections of your ear just behind the eardrum. Ear infections can be painful because of inflammation and fluid buildup in the middle ear.

Ear infections can be chronic or acute.

Acute ear infections are painful but short in duration.
