Hands-On Activities for Teaching Scientific Method in 7th Grade

The scientific method is a fundamental concept in science education. It provides students with a structured approach to investigating and understanding the world around them. In 7th grade, it is important to engage students with hands-on activities that not only teach them the steps of the scientific method but also make learning enjoyable and memorable. This article will discuss some exciting and interactive lesson plans for teaching the scientific method in 7th grade science classes.

Introduction to the Scientific Method

Before diving into specific activities, it is essential to introduce the scientific method to students. Start by explaining each step – observation, question, hypothesis, experiment, data analysis, and conclusion – using real-life examples. To make it more engaging, consider using multimedia resources such as videos or interactive presentations that highlight how scientists use these steps in their research.

Activity 1: The Bubble Gum Experiment

One popular activity for teaching the scientific method is the bubble gum experiment. Start by posing a question like “Does chewing gum affect concentration?” Have students form hypotheses and design an experiment to test their hypotheses.

Provide each student with a piece of bubble gum and ask them to chew it for a specified period while taking concentration tests periodically. Students can record their observations and analyze the data collected from their classmates.

This activity not only reinforces the steps of the scientific method but also allows students to understand how variables can be controlled in an experiment.

Activity 2: The Egg Drop Challenge

Another engaging activity that teaches both problem-solving skills and the scientific method is the egg drop challenge. Divide students into teams and provide them with various materials like rubber bands, straws, tissue paper, etc.

Challenge them to design a contraption that will protect an egg from breaking when dropped from a height. Encourage students to think critically about what factors might affect whether or not an egg breaks upon impact.

Through this activity, students will learn how to formulate a hypothesis, design and carry out an experiment, collect data, and draw conclusions based on their findings. It also promotes teamwork and creativity.

Activity 3: Investigating Water Density

To explore the concept of density and its relation to water, provide students with different liquids such as oil, syrup, and water. Ask them to hypothesize which liquid is the densest.

Then, provide them with various objects like paper clips or coins and ask them to predict whether each object will sink or float in the liquids provided. Students can test their hypotheses by conducting experiments and recording their observations.

This activity not only teaches students about density but also reinforces the steps of the scientific method by encouraging them to make predictions, conduct experiments, collect data, analyze results, and draw conclusions.


Teaching the scientific method through hands-on activities in 7th grade science classes is essential for fostering curiosity and critical thinking skills in students. The activities discussed in this article – bubble gum experiment, egg drop challenge, and investigating water density – provide engaging ways for students to understand the scientific method while enjoying themselves. By incorporating these interactive lesson plans into your curriculum, you can inspire a lifelong passion for science in your 7th grade students.
