Acquired & Inherited Traits

Traits are special qualities or characteristics that make us who we are. There are two types of traits: acquired traits and inherited traits. Inherited traits are traits that are passed down from our parents to us. These traits are determined by our genes, which are like tiny instructions inside our cells. Our genes tell our […]

The Stages of Life

All living things go through stages in their life. It’s like a big adventure, but it happens over a long time. Every living thing starts from birth, grows, reproduces, and then dies. It’s a cycle that happens to everything from tiny insects to big animals like elephants. Let’s explore the stages of life a little […]

The Cells In Our Bodies Combine To Form Organs And Organ Systems

Our bodies are made up of tiny things called cells. Cells are like tiny building blocks that come together to make us whole. Just like how lego pieces can come together to make a castle, our cells come together to make our bodies! Cells are so small that you can’t even see them with your […]

My Body Is Made Out of Cells

Did you know that our bodies are made up of tiny living things called cells? That’s right, just like how a building is made up of bricks, our bodies are made up of trillions of cells! Cells are like tiny bricks, and each one is important to keeping us healthy and working properly. They have […]

Our Body Parts Allow Us To Thrive

Weather And Seasons

Weather is what we see and feel outside every day. It can be sunny, rainy, windy, or snowy. The weather is always changing, and sometimes it can be different in different places. The seasons have an effect on the weather. There are four seasons: spring, summer, fall, and winter. Each season has different weather. In […]

Engineers Design Structures To Be Weatherproof

Engineers have an important job! They build things like buildings, bridges, and roads that we use every day. But when they build these things, they have to make sure they are safe and strong. And one of the things they have to think about is the weather. Why do they need to think about the […]

What Is Climate?

Climate is the pattern of weather that a place experiences over a long period of time, usually 30 years or more. This pattern includes average temperatures, rainfall, and wind patterns. Weather, on the other hand, is the short-term condition of the atmosphere in a specific place at a specific time. It includes things like today’s […]

Engineers Have To Account For The Weather

Climate is the long-term pattern of weather that a place experiences over a period of time, usually 30 years or more. This includes things like average temperature, rainfall, and wind patterns. Engineers are people who design and build things like homes, bridges, and other structures. They have to take into consideration the climate of an […]

Why This Teacher Left Public Education, What I’ve Learned About Homeschooling

It was one year ago this week, during the Christmas break, that I left my position as a middle school science teacher after spending a decade working faithfully in the system. During my tenure I was selected as teacher of the year, science department chair of the year for the entire state of Utah, and […]


Sharks are a group of predatory fish that have been around for over 400 million years. These fascinating creatures are found in oceans around the world, and they are known for their streamlined bodies, sharp teeth, and powerful jaws. There are over 500 species of sharks, and they come in a wide range of sizes, […]

The Cretaceous Period

The Cretaceous period was the final of the three major dinosaur eras, and it lasted from approximately 145 to 66 million years ago. During this time, the Earth’s climate was warm and humid, and the continents were fully separated. The Cretaceous period saw the evolution of many advanced and specialized dinosaur species, such as the […]

The Jurassic Period

The Jurassic period was the second of the three major dinosaur eras, and it lasted from approximately 201 to 145 million years ago. During this time, the Earth’s climate was warmer and more humid, and the continents were starting to drift apart. The Jurassic period saw the rise of many large and impressive dinosaur species, […]

The Triassic Period

The Triassic period was the first of the three major dinosaur eras, and it lasted from approximately 252 to 201 million years ago. During this time, the Earth’s climate was hot and dry, and the continents were much closer together than they are today. The Triassic period saw the rise of the first dinosaurs, as […]

The Three Dinosaur Eras

There are several different types of supernovae, […]

Snowflake Formation

Snowflakes are delicate and intricate crystals of ice that form in the Earth’s atmosphere. These beautiful snowflakes are a type of precipitation, which means that they form from water vapor that condenses and freezes in the air. The process of snowflake formation begins when water vapor in the air cools and condenses into tiny water […]

Why Are The Tropics Warm? Why Are The Poles Cold?

The poles are cold and the tropics are warm because of the way the Earth’s orbit around the sun and the tilt of the Earth’s axis affects the amount of sunlight different parts of the Earth receive. The Earth orbits, or travels around, the sun in a path that is shaped like an oval. As […]

What Causes The Seasons?

The seasons are caused by the Earth’s orbit around the sun and the tilt of the Earth’s axis. The Earth orbits, or travels around, the sun in a path that is shaped like an oval. It takes about 365.24 days for the Earth to make one complete orbit around the sun. As the Earth orbits […]

What Causes Day & Night?

Day and night are caused by the Earth’s rotation on its axis. The Earth rotates, or spins, on an imaginary line that runs through the North Pole and South Pole. It takes about 24 hours for the Earth to make one complete rotation. As the Earth rotates, different parts of the Earth are exposed to […]
