Another fun demonstration to add to a science unit, use for a science night, or show students just for fun. No prep time or materials? Use the videos at the end of this post to prompt a conversation about science! Depending on the age of your students this could be demonstrated by a small team of capable students. All you need is two balloons of the same size, about a meter of string, and a drinking straw. The materials are so common students will be able to repeat the activity at home. 🙂 Inflate two balloons to the same size. Tie …
Need a quick thought provoking demonstration that inspires a conversation in your classroom? Perhaps another activity to demonstrate air pressure that will enrich your weather or physics unit? All you’ll need is a wooden spool, an index card, and a thumbtack. Take a deep breath and exhale slowly to show students the power of air or let Dr. Boyd F Edwards demonstrate it for you! Trim a 3†x 5†index card in half to create a 3†x 2.5†card. Push a tack into the center of the card.  Place the point of the tack into the tube in the center of a wooden …
It’s April, almost May. Need a quick activity to punch up the enthusiasm in your science class? This activity could be part of a weather unit with air and wind. It could be added to a physics unit about force and air pressure. It’s a great demonstration that students can share with family members at a science night or open house. Â Turn on the hair dryer and aim the flow of air up. Carefully balance a ping-pong ball in the stream of air. Gently tilt the hair dryer. How far can you tilt the hair dryer before the ball …
