Science Experiments


The lesson introduces young students to the basics of science experiments, including the steps of the scientific method and how they are used.  Every student enjoys hands-on science activities; they are entertaining, but students must discover the concept behind the activity or experiment, such as the answers to questions that begin with why, what, when, etc.  The teacher is encouraged to plan experiments for students to observe and to conduct themselves, either alone or cooperatively with other classmates.

The lesson introduces your students to science experiments, including why they are performed and why they are important.  Students are briefly introduced to the scientific method, the rules to doing experiments. It is stressed that science experiments are not just entertaining, they always answer a question.  It is recommended teachers provide some small science experiments for students to try so they gain hands-on experience that will help them understand the process.

Sample Classroom Procedure / Teacher Instruction:  

  1. Plan and conduct a simple science experiment to open the lesson, but prior to the experiment, ask students a question related to a possible outcome.
  2. Allow for responses and discussion. Conduct the experiment.  Ask students to explain what happened, what could have changed the outcome, what have they learned from the experiment, etc.
  3. Allow for responses and discussion. Ask students why it is important to conduct experiments.
  4. Allow for responses and discussion. Introduce Science Experiments.
  5. Distribute Science Experiments content pages. Read and review the information with the students.  Save the final question for the lesson closing.  (Conduct the paper towel experiment while reviewing the 8 steps.)  Use the additional resources to enhance understanding.
  6. Distribute Activity page. Read and review the instructions.  Pair students.  Assign an experiment to the class.  (The teacher may decide to demonstrate an experiment instead of each pair of students conducting their own experiment.  If this is done, students respond to and discuss the activity questions one-by-one.)  Allow students sufficient time to complete the assigned experiment and respond to the questions.  Assist students when necessary.
  7. Once completed, students share their responses, observations, and other thoughts and ideas about what they have learned by conducting the experiment.
  8. Distribute Practice page. Check and review the students’ responses.  Ask students to correct false statements.
  9. Distribute the Homework page. The next day, check and review the students’ responses.  You may encourage students to conduct the two experiments at home.
  10. In closing, ask students: What is your favorite thing about doing experiments? Why?  What is your least favorite thing about doing experiments?  Why?
