Life Science Playlist - Full Year-All Subjects

 

Enjoy this Life Science playlist!  I've created short, 2–4 minute videos covering every major Life Science topic. Each video provides a clear, easy-to-understand explanation to help students learn and review important concepts.

With over 30 years of experience teaching science, I've used my classroom experience to make these videos engaging, informative, and student-friendly. I hope they make learning Life Science a little easier!

Tea Bag Rocket - Convection Current Demonstration

 

What Is Convection?

Need a fun and exciting way to demonstrate convection currents?

Convection is the transfer of heat through the movement of a fluid, such as a liquid or a gas. When air or water is heated, it expands, becomes less dense, and rises. Cooler, denser fluid moves in to take its place, creating a convection current.

You can observe convection in several everyday examples:

• Lava lamps: Warm liquid rises and cooler liquid sinks, creating a continuous motion.

• Boiling water: Heated water rises while cooler water sinks, creating circulating currents.

• Tea bag rockets: Heated air rises and helps lift a lightweight tea bag into the air.

How to Make a Tea Bag Rocket

Materials

• One lightweight, empty tea bag

• Scissors

• A lighter or long-reach lighter

Instructions

1. Prepare the tea bag. Carefully cut off the string and remove the staple, if present.

2. Empty the tea. Unfold the tea bag and pour out the tea leaves.

3. Create a cylinder. Carefully shape the empty tea bag into an upright cylinder and place it on a nonflammable surface.

4. Light the top. With adult supervision, carefully ignite the top edge of the tea bag and step back to observe what happens.

As the tea bag burns downward, the lightweight paper becomes less able to support itself. The heated air rises, and the remaining ash-light structure can lift into the air like a tiny rocket.

Fractions for Adults Playlist

 

Are you an adult who still struggles with fractions? This playlist is for adults who want to strengthen their fraction skills. I break each problem down step-by-step with clear explanations and examples so you can build confidence and finally make sense of fractions.

The playlist contains over forty videos and covers the basics of fractions, plus adding, subtracting, dividing, and multiplying fractions. You'll also find lessons on simplifying fractions, equivalent fractions, mixed numbers, improper fractions, and finding common denominators.

Whether you're reviewing math for yourself, preparing for a test, helping a student, or simply want to refresh skills you haven't used in years, these videos provide a straightforward way to practice. Start with the basics and work your way through the playlist at your own pace.
