Have you ever wondered if you can burp in space? Well, in space, there’s no gravity, which means food and gases float around together in your stomach. If you try to burp, everything might come out, not just the gas! So, it’s best to avoid burping when you’re floating among the stars.
Our ears are amazing because they help us keep our balance! The ear has three main parts: the outer ear, middle ear, and inner ear. The inner ear works with our eyes and muscles to help us stay balanced during different activities.
Inside the inner ear, there are three tiny tubes called semicircular canals. They are filled with a special fluid and have tiny hair cells called cilia. When you move your head, the fluid moves, making the cilia send signals to your brain about which way your head is moving.
Imagine you’re on a merry-go-round. As you spin, the fluid in your semicircular canals moves too. When the ride stops, the fluid keeps moving for a bit, which can make you feel like you’re still spinning!
Ever wonder why coffee helps you stay awake? It’s all about a chemical in your brain called adenosine. As you go about your day, adenosine builds up and makes you feel sleepy by slowing down brain activity.
Caffeine, which is in coffee, looks a lot like adenosine. When you drink coffee, caffeine takes the place of adenosine in your brain, blocking it from making you sleepy. This keeps your brain active and helps you stay awake!
Saturn’s rings are one of the most beautiful sights in our solar system. Scientists think these rings might have formed because of something called the Roche limit. This is the distance from a planet where an object can be pulled apart by the planet’s gravity.
One idea is that a moon or comet got too close to Saturn and was torn apart by its gravity. The pieces then spread out and formed the rings we see today.
When you get a cut or scrape, your skin works hard to heal itself. Your skin has a protein called collagen, which helps keep it firm and strong. When you’re injured, cells called fibroblasts make extra collagen to repair the wound.
Normally, collagen forms a basket-weave pattern, but when a scar forms, the collagen lines up in one direction. This is why scars look different from the rest of your skin.
Imagine you’re an astronaut! Create a small experiment using a sealed plastic bag filled with a mix of water and air. Shake it gently and observe what happens. Discuss with your classmates why burping in space might be tricky and how gravity affects this process on Earth.
Test your balance by walking along a straight line with your eyes closed. Then, try it again with your eyes open. Discuss how your ears and eyes work together to help you balance and what happens when one sense is removed.
In pairs, act out a scene where one student is adenosine trying to make the brain sleepy, and the other is caffeine trying to block adenosine. Discuss how caffeine affects your alertness and why it might not be a good idea to drink coffee before bed.
Create a model of Saturn and its rings using paper plates and colored paper. Discuss how the Roche limit might have caused the formation of Saturn’s rings and what materials could make up the rings.
Use clay to simulate how scars form. Roll out a piece of clay and make a small cut. Then, use additional clay to fill the cut, showing how collagen lines up differently in a scar. Discuss why scars look different from normal skin.

**It’s AumSum Time!**
**Can we burp in space?**
In space, there is no gravity, so food and gases float together. If you were to burp, everything would come out, so it’s best not to burp in space.
**Topic: Ear.**
**How do ears help with balancing?**
Ears play a crucial role in maintaining balance. Our ears consist of three parts: the outer ear, middle ear, and inner ear. The inner ear works in conjunction with our eyes and muscles to help us maintain balance during various activities.
The inner ear contains three semicircular canals: the superior, posterior, and lateral semicircular canals. Each canal is positioned differently and contains fluid called endolymph and hair cells known as cilia. When we move our head, the fluid shifts, causing the cilia to move and send signals to the brain about the direction of our head movement.
– The superior semicircular canal helps the brain understand up-and-down movements.
– The posterior semicircular canal helps with tilting motions.
– The lateral semicircular canal assists with side-to-side movements.
When you ride a merry-go-round, the fluid in the semicircular canals moves with you. When the ride stops, the fluid continues to move due to inertia, leading to a sensation of still being in motion, which can affect your balance.
**Topic: Caffeine.**
**How does coffee keep you awake?**
When we engage in daily activities, a by-product called adenosine is produced, which slows down brain activity and makes us feel sleepy. Adenosine binds to specific receptors in the brain, activating them.
Caffeine, found in coffee, is structurally similar to adenosine. When consumed, caffeine binds to the adenosine receptors, blocking adenosine from attaching. As a result, brain activity remains elevated, keeping us awake.
**Why does Saturn have rings?**
Scientists believe Saturn’s rings may be related to the Roche limit, which is the distance from a planet where objects in orbit can be torn apart by the planet’s gravitational pull. One theory suggests that a celestial body, such as a moon or comet, may have come too close to Saturn, exceeding this limit and being torn apart. The remnants then formed the beautiful rings we see today.
**How do scars form?**
A scar forms when skin tissue heals after an injury. Our skin contains collagen, a structural protein produced by fibroblasts that keeps the skin firm. When injured, fibroblasts produce more collagen to heal the wound. However, instead of forming a basket-weave pattern, the collagen aligns in a single direction, resulting in a scar that appears different from normal skin.

Burp – A release of gas from the stomach through the mouth, often accompanied by a sound. – During digestion, a burp can occur when gas escapes from the stomach.
Gravity – The force that pulls objects toward each other, especially the pull of the Earth that makes things fall to the ground. – Gravity is the reason why apples fall from trees to the ground.
Ear – The organ on the side of the head that detects sound and helps with balance. – The ear helps us hear music and keeps us balanced when we walk.
Balance – The ability to stay steady and not fall over, often maintained by the inner ear. – Gymnasts need good balance to perform on the balance beam.
Semicircular – Shaped like a half-circle; in biology, often refers to the semicircular canals in the ear that help with balance. – The semicircular canals in our ears help us keep our balance when we spin around.
Fluid – A substance that can flow, such as a liquid or gas. – The fluid in the semicircular canals of the ear helps us detect movement and maintain balance.
Cilia – Tiny hair-like structures that can move and are found on the surface of some cells, helping with movement or sensing the environment. – Cilia in the respiratory tract help move mucus out of the lungs.
Caffeine – A natural chemical found in coffee and tea that can stimulate the brain and body. – Caffeine can make people feel more awake and alert by affecting the nervous system.
Rings – Circular bands or structures; in biology, often refers to growth rings in trees or rings in the structure of certain molecules. – Scientists can tell the age of a tree by counting the rings in its trunk.
Collagen – A protein that is an important part of skin, bones, and connective tissues, providing strength and structure. – Collagen helps keep our skin firm and our joints flexible.
