Imagine you want to visit Disneyland, but you don’t live in Anaheim, California, and you’ve never been there before. How would you find your way? You might think about driving, but which direction would you go? Which roads would you take? Some of you might say you’d use Google Maps, but what if you couldn’t? You might ask someone for directions or use a road map. With some help, you could find your way to Disneyland!
Scientists are curious people who love to learn about the world and how everything works. They like to invent new things and make old things better. To help them figure things out, scientists use a special process called the scientific method. It’s like a roadmap that helps them answer questions and discover how things work.
Let’s explore the steps of the scientific method:
The first step is observation. This means noticing something interesting and asking questions about it. For example, you might wonder, “Why is the sky blue?” or “What makes water freeze?” You use your senses—seeing, hearing, smelling, tasting, and touching—to make observations.
Next is forming a hypothesis. This is like making a smart guess about what you think will happen. It usually sounds like, “If I do this, then I think this will happen.” Your hypothesis should be something that others can test too.
Now comes the fun part—experimentation! You do experiments to test your hypothesis. It’s important to do your experiments carefully and change your methods if needed. Other people should be able to do the same experiment and get similar results.
After experimenting, you look at the results and come to a conclusion. Your conclusion might show that your hypothesis was right, or it might show that you need to do more testing. Keeping a notebook to write down what you find is very helpful.
In places where winters are very cold, water freezes at 0 degrees Celsius (32 degrees Fahrenheit). When it rains, the water can turn into ice and snow, which can be dangerous for drivers. You might notice that salt melts ice.
For step 1, our observation is that salt seems to melt ice. For step 2, we can hypothesize that if we use salt, then the ice will melt.
For step 3, we would design an experiment. We could use a plastic cup or bowl with water, place it in the freezer, and then sprinkle salt on the ice to see if it melts. It’s important to keep precise notes throughout the experiment.
Finally, you can repeat your experiment with different amounts of salt or water to see what works best.
Think about the light bulb. It wasn’t invented by just one person; it took many years and many experiments by different people. Thomas Edison, one of the inventors, said, “I have not failed. I’ve just found 10,000 ways that won’t work.” This shows how important it is to keep trying and learning.
Now it’s your turn! Observe, hypothesize, experiment, and conclude. You might discover something amazing and make the world a better place. For more fun experiments using the scientific method, check out the Clarendon Learning activity page.

Ice Melting Race: Gather some ice cubes and place them on a tray. Sprinkle different amounts of salt on each ice cube and observe which one melts the fastest. Record your observations in a notebook. Discuss why you think some ice cubes melted faster than others. What did you notice about the amount of salt and the melting speed?
Colorful Observations: Go outside or look around your home and choose an object or scene to observe. Use your senses to describe it in detail. What colors do you see? What sounds do you hear? Can you smell anything? Write down your observations and think about any questions you have about what you observed. Share your observations with a friend or family member and see if they notice anything different.
Hypothesis Drawing: Think of a simple question you have about the world, like “What happens to a plant if it doesn’t get sunlight?” Draw a picture of what you think will happen (your hypothesis). Then, if possible, conduct a simple experiment to test your hypothesis, like placing a plant in a dark area and observing it over a few days. Draw what you observe and compare it to your original hypothesis. What did you learn?

Clarendon Learning explores the scientific method. If you wanted to go to Disneyland and didn’t live in Anaheim, California, and had never been there, how would you get there? You might say you’d drive, but what direction would you go? Which roads would you take? Some of you may have said you’d use Google, but what if you didn’t have access to that? Perhaps you’d consider asking someone for directions or using a road map. With a little luck, you could arrive at Disneyland!
Scientists are always curious about the world and how everything works. They are interested in inventing new things and improving existing ones. While conducting their work, scientists use a kind of roadmap called the scientific method. The scientific method is a series of steps designed to help figure things out and discover answers to questions about how things work.
For example, consider the incandescent light bulb. Its invention was not the work of just one person; it took many years, numerous experiments, and contributions from many individuals. Can you imagine life without the light bulb? It plays a crucial role in our daily lives.
The scientific method, when followed properly, can help answer important questions. Let’s look at the steps involved:
1. **Observation**: This is the first step. If you’re curious about the world, you might ask questions like, “Why is the sky blue?” or “What makes water freeze?” Observation involves using one or more of the five senses: hearing, seeing, smelling, tasting, and touching.
2. **Hypothesis**: This is an educated guess or statement. It usually follows the format: “If I do this, then I believe this will happen.” Your hypothesis should be testable by others.
3. **Experimentation**: This is the fun part! You conduct experiments to test your hypothesis. It’s important to carry out your experiments carefully and to adjust your methods if necessary. Other people should be able to replicate your experiments.
4. **Conclusion**: After conducting your experiments, you will analyze the results. Your conclusion may support your hypothesis or indicate that further testing is needed. Keeping a notebook to record your findings is essential.
Let’s run through a simple exercise to see how the scientific method works. In areas where winters can be very cold, water freezes at 0 degrees Celsius (32 degrees Fahrenheit). When it rains, the water can turn to ice and snow, which can be dangerous for drivers. You might observe that salt melts ice.
For step 1, our observation is that salt seems to melt ice. For step 2, we can hypothesize that if we use salt, then the ice will melt.
For step 3, we would design an experiment. We could use a plastic cup or bowl with water, place it in the freezer, and then sprinkle salt on the ice to see if it melts. It’s important to keep precise notes throughout the experiment.
Finally, you can repeat your experiment with different amounts of salt or water to see what works best.
Back to the light bulb: Thomas Edison, among others, played a significant role in its development. He famously said, “I have not failed. I’ve just found 10,000 ways that won’t work.”
So, go ahead! Observe, hypothesize, experiment, and conclude. You have the potential to make the world a better place. For more great experiments using the scientific method, check out the Clarendon Learning activity page.
