How To Teach Science
Kids are curious and always looking to explore, discover, check out, and experiment to discover why things do what they do, move as they move, or change as they change! My son is now 13, and we started with simple science activities around three years of age with simple baking soda science.
Here are great tips for making science experiments enjoyable at home or in the classroom.
Safety first: Always prioritize safety. Use kid-friendly materials, supervise the experiments, and handle potentially hazardous substances yourself.
Start with simple experiments: Begin with basic experiments (find tons below) that require minimal setup and materials, gradually increasing complexity as kids gain confidence.
Use everyday items: Utilize common household items like vinegar and baking soda, food coloring, or balloons to make the experiments accessible and cost-effective.
Hands-on approach: Encourage kids to actively participate in the experiments rather than just observing. Let them touch, mix, and check out reactions up close.
Make predictions: Ask kids to predict the outcome before starting an experiment. This stimulates critical thinking and introduces the concept of hypothesis and the scientific method.
Record observations: Have a science journal or notebook where kids can record their observations, draw pictures, and write down their thoughts. Learn more about observing in science. We also have many printable science worksheets.
Theme-based experiments: Organize experiments around a theme, such as water, air, magnets, or plants. Even holidays and seasons make fun themes!
Kitchen science: Perform experiments in the kitchen, such as making ice cream using salt and ice or learning about density by layering different liquids.
Create a science lab: Set up a dedicated space for science experiments, and let kids decorate it with science-themed posters and drawings.
Outdoor experiments: Take some experiments outside to explore nature, study bugs, or learn about plants and soil.
DIY science kits: Prepare science experiment kits with labeled containers and ingredients, making it easy for kids to conduct experiments independently. Check out our DIY science list and STEM kits.
Make it a group effort: Group experiments can be more fun, allowing kids to learn together and share their excitement. Most of our science activities are classroom friendly!
Science shows or documentaries: Watch age-appropriate science shows or documentaries to introduce kids to scientific concepts entertainingly. Hello Bill Nye and the Magic Schoolbus! You can also check out National Geographic, the Discovery Channel, and NASA!
Ask open-ended questions: Encourage critical thinking by asking open-ended questions that prompt kids to think deeper about what they are experiencing.
Celebrate successes: Praise kids for their efforts and discoveries, no matter how small, to foster a positive attitude towards science and learning.
What is the Scientific Method for Kids?
The scientific method is a way scientists figure out how things work. First, they ask a question about something they want to know. Then, they research to learn what’s already known about it. After that, they make a prediction called a hypothesis.
Next comes the fun part – they test their hypothesis by doing experiments. They carefully observe what happens during the experiments and write down all the details. Learn more about variables in experiments here.
Once they finish their experiments, they look at the results and decide if their hypothesis is right or wrong. If it’s wrong, they devise a new hypothesis and try again. If it’s right, they share their findings with others. That’s how scientists learn new things and make our world better!
Go ahead and introduce the scientific method and get kids started recording their observations and making conclusions. Read more about the scientific method for kids.
