designing an experiment, collecting and analyzing data, and drawing a conclusion. This is sometimes also referred to as scientific inquiry. A hypothesis is a possible explanation for an observation. A good scientist will design a controlled experiment to test their hypothesis. In a controlled experiment, only one variable is tested at a time.

In Science experiments, it is very important to “control the variables” so that there is only ONE independent variable and ONE dependent variable. We “control the variables” by making anything else that could change during the experiment into a constant. For example, if you are doing an experiment to find out what

Activities to Teach Scientific Process Skills. 1) Observations & Inference – I like to group these two skills because they are often used together. Observation refers to both describing, such as using the five senses (qualitative) and measuring (quantitative). Inference is the logical conclusion drawn about an object or event based on an ...

There seem to be several variations out there, but let’s pause and nail down the basics of the scientific method. Here is a quick review if you need a brush-up:
The first step is to look at the world around you. What do you notice? What interests you? What are you curious about? Things outside? In the kitchen? What do you not understand or have questions about? What would you like to know more about? Example: My mom waters her flowers every day, but she doesn’t water the grass. But the grass and flowers lo...
Work with your young scientists to develop a question from their observations. Example: Do flowers really need to be watered more than the rain that waters the grass? Is my mom just wasting her time? ****Some science curriculum will teach that you should have a step of research at this point in the scientific method. Feel free to do that with older...
Help your student to make a hypothesis (kids usually love saying this word!) about what they think is the answer to their question. Depending on the age of the child, tell them it is an educated guess or a prediction. Example: I predict that the flowers will do just fine without extra water from my mom.
Obviously, this is the fun part of science. Kids get to put the books and pencils aside and start building their own science experiments! Your students will likely need help with their experimental design. Definitely dig in and help them figure out the best way to test their hypothesis. For older kids, you might introduce the concepts of independen...
Now that the experiment is over, it’s time to sit down and do some data analysis. Which is fancy science talk for looking closely at the results of your experiment. Are there any patterns or trends in your data collection? Did anything unexpected happen? What did the experiment show you? Example: All my flowers are turning brown, but the grass look...
Look at the results of your experiment and compare them to your prediction. Was your hypothesis correct or incorrect? Example: My hypothesis was incorrect. The flowers did not thrive on the same amount of water that the grass gets.
At the end of the experiment, you must write out what you can conclude from your experiment. Older kids should be encouraged to follow up with further questions they have from the results of the experiment. Example: I conclude that the grass in my yard does not need as much water as the flowers. As a question for further study, I would like to know...
Now that we’ve brushed up on our knowledge of the scientific method, let’s dive into these worksheets! This worksheet is actually a colorful poster displaying all the steps of the scientific method for your students! I recommend printing it on cardstock or laminating it. It’s the perfect thing to have displayed in your homeschool or science classes...
You might be wondering why there wasn’t a “typical” worksheet in this post. Such as a cut and paste, crossword, or match with an answer key. The reason is that hands-on activities are the best way to teach the scientific method – not worksheets. Kids will learn science and *remember* it more when they get to DO it. And as you know, that’s actually ...
The six steps of the scientific method include: 1) asking a question about something you observe, 2) doing background research to learn what is already known about the topic, 3) constructing a hypothesis, 4) experimenting to test the hypothesis, 5) analyzing the data from the experiment and drawing conclusions, and 6) communicating the results ...
