Did you know that cashews grow on apples? It’s true! The apple is just an extra part of the plant, while the cashew nut grows on top of it. Isn’t that fascinating?
Here’s a surprising fact: mushrooms are more closely related to animals than to plants. This means that humans and mushrooms share a more recent common ancestor than mushrooms do with plants. Who would have thought?
We often think trees grow from the ground, but they actually grow from the air too! Trees take in carbon dioxide from the air, and with the help of sunlight, they release oxygen. The carbon combines with water to form the tree’s structure. So, trees are like nature’s magic makers!
Did you know that Lake Superior has enough water to cover all of North and South America with one foot of water? And get this: there are more stars in the universe than all the grains of sand on Earth’s beaches. That’s a lot of stars!
Your brain is incredible! The cerebral cortex alone has about 125 trillion synapses, which is like having the same number of stars as 1,500 Milky Way galaxies. But did you know that atoms, which make up everything, are mostly empty space? This means that everything, including you, is mostly nothing!
Your body is constantly changing. Every 10 years, all the atoms in your body are replaced, so you’re like a whole new person! Plus, there are more bacterial cells in your body than your own cells. Isn’t that wild?
If you’re 18 years old, you have about 3,200 to 3,500 weekends left in your lifetime. And you only have about 57 summers left. Make the most of them!
Dragonflies have legs, but they can’t walk; they can only land. And in a group of clownfish, if the female is gone, the most dominant male will turn into a female. Nature is full of surprises!
The mighty Tyrannosaurus rex is closer in time to us than it is to the Stegosaurus. And Cleopatra lived closer to the first moon landing than to the building of the pyramids. History is full of amazing timelines!
And just for fun, now that I’ve mentioned it, you’re probably breathing manually. Funny how that works, right?

Take a closer look at how cashews grow. Research and create a poster that illustrates the growth process of a cashew nut on a cashew apple. Include fun facts and diagrams to share with your classmates.
Investigate the evolutionary relationship between mushrooms, plants, and animals. Create a simple family tree diagram that shows how mushrooms are more closely related to animals than plants. Present your findings to the class.
Conduct an experiment to understand how trees grow from the air. Use a small plant and measure its growth over a few weeks. Record how sunlight and carbon dioxide contribute to its development. Share your results in a class presentation.
Organize a night sky observation session. Use a telescope or binoculars to observe stars and constellations. Discuss how the number of stars compares to grains of sand on Earth. Write a short report on your observations.
Create a timeline that includes the T. rex, Stegosaurus, Cleopatra, and the moon landing. Use this timeline to understand the surprising connections between these historical events. Present your timeline to the class and discuss what you found most surprising.
Sure! Here’s a sanitized version of the transcript:

You may have heard many interesting facts about life, but did you know that cashews grow on apples? In this case, the apple is simply an accessory fruit, with the cashew growing on top.
How about the fact that mushrooms are more closely related to animals than to plants? The most common ancestor between humans and mushrooms is more recent than that of mushrooms and plants.
Trees actually grow out of the air, not just the ground. While they do receive some minerals from the soil, the carbon dioxide from the air goes into the tree, and with the help of the sun, oxygen is released. This carbon combines with water to create the substance of the tree.
Did you know that there is enough water in Lake Superior to cover all of North and South America with one foot of water? Or that there are more stars in the visible universe than all the grains of sand on all the beaches of the Earth?
Interestingly, the number of synapses in your brain’s cerebral cortex alone—about 125 trillion—is equivalent to the number of stars that would fill 1,500 Milky Way galaxies. However, an atom is about 99.99% empty space, making everything in the universe mostly nothing, including your body, which is constantly replacing its cells. In fact, every 10 years, your entire body has replaced itself. This means that every atom in your body is different now, so you have no more in common with your previous self than any other human being who has lived or will ever live.
Moreover, there are more bacterial cells in your body than actual somatic body cells. If you’ve made it to age 18, you have, on average, about 3,200 to 3,500 weekends left in your lifetime. More importantly, you only have about 57 summers left.
Did you know that while dragonflies have legs, they cannot walk, only land? In a population of clownfish, if the female dies or is removed, the most dominant male will become a female.
The Tyrannosaurus rex, in terms of time, is closer to today than to when the Stegosaurus roamed the Earth. Similarly, Cleopatra lived closer to the first moon landing than to the construction of the pyramids.
And just for fun, when I say it, you are now breathing manually.

Cashews – A type of nut that grows on a tropical tree and is often used in cooking and snacks. – Cashews are rich in healthy fats and proteins, making them a nutritious snack for students studying biology.
Mushrooms – Fungi that grow in damp environments and can be used as food or in scientific research. – Scientists study mushrooms to understand their role in ecosystems and their potential medicinal properties.
Trees – Large plants with a trunk, branches, and leaves, which produce oxygen and provide habitats for many organisms. – Trees play a crucial role in the carbon cycle by absorbing carbon dioxide and releasing oxygen into the atmosphere.
Carbon – A chemical element that is essential for all living organisms and is a key component of organic molecules. – Carbon is found in all living things and is a fundamental building block of life on Earth.
Oxygen – A chemical element that is essential for respiration in most living organisms and is a major component of the Earth’s atmosphere. – Plants release oxygen during photosynthesis, which is vital for animals and humans to breathe.
Bacteria – Microscopic single-celled organisms that can be found in various environments and can be beneficial or harmful. – Bacteria in the soil help decompose organic matter, recycling nutrients back into the ecosystem.
Brain – The organ in animals that controls thought, memory, emotion, and many other functions. – The human brain is a complex organ that scientists study to understand how we think and learn.
Atoms – The basic units of matter that make up all substances, consisting of protons, neutrons, and electrons. – Everything around us, including living organisms, is made up of atoms that combine to form molecules.
Dragonflies – Insects with long bodies and two pairs of strong, transparent wings, often found near water. – Dragonflies are studied by biologists for their role in controlling mosquito populations and their unique flying abilities.
Dinosaurs – A group of reptiles that lived millions of years ago and are now extinct, known for their large size and diverse species. – Paleontologists study dinosaur fossils to learn about the Earth’s history and the evolution of life.
