Presenting to Young Audiences
Whenever you talk about chemistry with young audiences, in classroom presentations or large public shows, you have a great opportunity to interest them in chemistry and inspire them to learn more. When you speak with kids about chemistry, try to remember to interest them in science while speaking in their terms.
Review these resources for additional tips and information:
Let the children know something about you as a person. Was there a special individual or event in your life that first aroused your interest in science? What do you most love about chemistry? What do you love most about your particular field? Keep in mind that you may be the only chemist these children have ever met!
Use a demonstration, introductory activity, or story to get the students’ attention and motivate them to want to find out more. Plan your lesson around a question that students will investigate with you. By the end of your lesson, students should be able to use evidence from their activities to answer the question. Children love science when it is taught as an extension of their natural curiosity.
Facilitate Thinking and Learning
Let the children learn by doing. Don’t tell them what to expect in a demo or hands-on activity. Let them see for themselves and then ask them to describe their observations. Encourage them to think about possible explanations for the results. If possible, provide time for the students to test their ideas.
Stimulate thinking by asking questions. Questions that ask children to make a prediction, give an explanation, state an opinion, or draw a conclusion are valuable. Make sure students have enough background so that they can honestly consider the possibilities. You may want to write a list of questions to ask students as you plan your lesson. The best questions require more than a yes or no answer.
Be conscious of your vocabulary. Try not to use a complicated word when a simple one will do. Define words that students may not know and use simple definitions that relate to them.
- Acids and bases are chemical terms which describe substances that are a part of your everyday life. Lemons, oranges, and grapefruit contain acids. Hand soap, dish detergent, and laundry detergent contain bases.
- You can find polymers all around you. For example, many of the toys that you play with, including anything plastic, are made of polymers. Many clothes are made from polymers. Polymers are chemical compounds that are made of chains of molecules linked together by chemical bonds.
Use analogies, models, or activities. For example, when discussing polymers, you could have young students stand up to make a model of a polymer with their bodies. Explain that one student could represent a monomer; two or more monomers can link arms to form a polymer.
Your classroom visit is an opportunity to introduce students to chemistry and inspire them to discover their world through science. Keep the following messages in mind:
- There’s a scientist in all of us. Anyone who is curious, observant, and questioning about the world we live in is already acting like a scientist.
- Chemistry is everywhere and contributes to everyone’s daily life. Anything that can be touched, tasted, smelled, seen or felt is made of chemicals.
- Chemists and chemistry drive innovations to discover solutions to problems and enhance our lives (e.g., find new drugs that can control disease, improve water and air quality, clean our environment, improve the food that we eat).
- Chemistry is an important profession, because careers in chemistry offer opportunities to change the world.
Ask the children what they liked—or didn’t like—about your visit. Ask the teacher to let you know what kids thought about the activity and how well it helped students learn the concept you were teaching. Use their suggestions to enhance your next effort.
Even though your activity is through, don’t close the door to learning. Invite the teacher to contact you again next year, offer to be a science pen pal for the class, or help set up an experiment that students can continue after you leave. Perhaps most importantly, leave a copy of ACS resources and materials for teachers and students and your business card so the class will have access to chemistry resources throughout the school year.
Next, find sample demonstrations and safety guides to help you plan and execute your demonstration.
Share your experience speaking to students about chemistry. How do you reach out to schools and plan activities?
