Science is a subject we all encounter in daily life, helping us understand how the world works. However, the best way for kids to truly grasp the complexities of science isn’t just by reading about it—it’s by doing it!
Science experiments are not only fun, but also play a key role in your child’s personal and educational development by offering numerous learning opportunities, from building critical thinking skills to encouraging creativity.
In this blog, we’ll explore what science experiments are, the different types, and the many benefits they provide for kids. Plus, we’ll also share some simple, fun science activities for you to try at home that are perfect for budding scientists of all ages!
What are science experiments?
Scientific experiments are practical investigations that test a hypothesis or answer a question by making observations, collecting data, and analysing results. Once enough evidence is gathered, a conclusion is drawn based on the findings.
They can explore many exciting areas within the following key scientific disciplines:
Chemistry
This is the study of matter; its properties and how different substances interact with each other. For example, chemistry experiments like mixing iodine with starch to produce a blue-black colour demonstrate chemical reactions and molecule formation. This can be used to test for starch in foods or detect contamination.
Physics
Physics focuses on the fundamental forces of nature, such as gravity, motion, and energy. Experiments in physics might include testing how objects move, measuring forces, or exploring electricity and magnetism to learn about the laws that govern everything and how they apply to technology, engineering and daily life.
Biology
Biology is the study of all living organisms, from the tiniest creatures to entire ecosystems. Biology experiments can involve observing plants, animals, or even microorganisms to learn about life cycles, growth, or behaviour. From this, we gain a deeper understanding of biodiversity and ecological balance.
Environmental Science
This field looks at how humans interact with the environment and the impact we have on the planet. Experiments in environmental science can be studying the effect of pollution or climate change on wildlife, air and water quality, and even human health.
Depending on the focus, science experiments are often carried out in controlled environments like laboratories, classrooms, natural settings such as forests or oceans, or even outer space, to ensure accurate and reliable results.
The different types of science experiments
In the world of science, experiments are broadly categorised into three main types: experimental (randomised control), quasi-experimental, and observational (non-experimental).
All three play a unique role in how scientists gather evidence and uncover new insights about the world. During Science lessons at school, kids may undertake the following types of experiments.
1. Experimental experiments
Experimental (or randomised control) experiments involve testing a hypothesis by changing one factor (the independent variable) and measuring its effect on another (the dependent variable). For example, a scientist might change the temperature of water to see how it affects the rate at which sugar dissolves. Essentially, they help us understand what causes certain outcomes and are great for finding clear answers.
2. Quasi-experimental experiments
Quasi-experimental experiments are similar to experimental ones, but scientists don’t have full control over the situation. For instance, they might look at how different bedtimes impact kids’ performance at school. While the researcher doesn’t control when kids go to bed, they can observe how early or late bedtimes impact grades and attention in class.
3. Observational experiments
Observational experiments (or non-experimental studies) involve recording what happens without changing variables. If researchers want to understand how animals behave in their natural habitat, they must observe without interfering. By collecting information on existing conditions or behaviours, they are useful for generating hypotheses and identifying patterns for further investigation.
How do experiments fit in with the scientific method?
Experiments are an important part of the scientific method, which is a step-by-step process that helps scientists (and curious kids) explore questions and test whether their predictions are accurate or not.
Here’s how it works:
- Ask a Question – Every experiment starts with a question, like “What makes plants grow faster?” or “What happens when you mix oil and water?”
- Do some research – Before testing, it’s helpful to learn a little about the topic. For example, we know plants need water and sunlight to grow.
- Make a hypothesis – A hypothesis is an educated guess about what will happen. For example, If a plant gets more sunlight, it will grow taller.
- Conduct the experiment – This is the fun part! Test your hypothesis by following a step-by-step experiment. Keep everything the same except for one variable, like giving one plant more sunlight than another.
- Observe and record results – Watch closely and take notes on what happens. Does the plant with more sunlight grow taller?
- Draw a conclusion – Based on your results, decide whether your hypothesis was correct or not. Either way, you’ve learned something new!
6 Benefits of science experiments for kids
Now that we’ve outlined what science experiments are and how they apply to real-world situations, let’s dive into six key benefits they offer for kids.
Science activities for kids do more than just support learning in the classroom; they also provide valuable skills and experiences that will help children throughout their lives and future careers.
1. Improves critical thinking
Science experiments are a great way for kids to develop critical thinking skills. As they engage in hands-on activities, they naturally start asking “why?” and “how?”. During a simple experiment like testing which materials float in water, children may predict which objects will float, then observe and reflect on the actual outcome.
This process helps them develop logical reasoning as they figure out why their predictions were right or wrong. Beyond school, kids can apply problem-solving skills to everyday situations like figuring out the best way to pack a suitcase for an upcoming trip.
2. Sparks intellectual curiosity
There’s something kind of magical about witnessing an experiment unfold in real-time, offering children a tangible connection to science. For example, watching a magnet pick up paper clips might make a child ask, “Why do magnets attract only certain metals?” Or, seeing a rainbow form through a prism, and wondering, “How does light create different colours?”
It’s moments like these which can ignite a sense of curiosity in kids, inspiring them to develop a lifelong love of learning. What’s more, it changes their perspective of the world around them, where they begin to see everyday occurrences, like puddles disappearing after it rains, as fascinating scientific processes waiting to be uncovered.
3. Enhances scientific literacy
Participating in science experiments helps kids enhance their scientific literacy. Through practical experience, they not only learn scientific concepts but also acquire the vocabulary needed to describe what they observe. For instance, when kids mix different liquids to study reactions, they start to understand terms like “solubility,” “chemical reaction,” or “pH.”
This foundational knowledge becomes a powerful tool as they continue their education, making more complex scientific concepts easier to grasp. Additionally, it will serve them well in everyday tasks, like knowing how to measure ingredients for baking so that the recipe turns out correctly.
4. Boosts creativity and self-confidence
One of the most exciting benefits of science experiments for kids is how they encourage creativity. Whether children are coming up with their own experimental ideas or figuring out how to solve problems during a school project, they’re flexing their creative muscles to explore different possibilities.
For example, if a child is tasked with creating a simple rocket using household materials, they might try different designs, test them out, and adjust them based on their observations. This trial-and-error process boosts their confidence, as they see firsthand how their ideas can lead to solutions.
5. Develops motor skills
Tasks like pouring liquids, mixing ingredients, using tools, or even arranging objects are all hands-on activities that help children develop fine motor skills. For instance, when kids make slime by mixing cornstarch and water, they need to carefully stir the mixture to see how its consistency changes.
These types of science activities for kids strengthen hand-eye coordination and dexterity as children must follow steps carefully to achieve the desired result. With practice, they will improve their ability to control small movements and develop better hand strength, which are all essential for writing, drawing, and using utensils.
6. Hands-on learning experiences
Unlike more passive forms of learning, such as reading or watching videos, science experiments allow children to actively engage with the material. By being directly involved in the process, they form a deeper understanding of the ideas taught in class.
A 2024 study by the Royal Society shows that 52% of students in years 7-11 are more motivated to learn science because of practical experiments. This hands-on approach not only boosts motivation for the subject but also helps concepts stick in their minds more effectively, leading to better long-term retention.
