Science for the Season

STEM Certified Educator and Digital Meteorologist, Jason Lindsay, (also known as Mr. Science) gets us Hooked on Science and shows us how to mix things up this Thanksgiving. California Live Contributor Berlin gets the details on the perfect pass time experiments for the whole family! Find the experiment details below. **Experiment #1** THANKSGIVING EGG DROP SCIENCE SAFETY PLEASE follow these safety precautions when doing any science experiment. • • ALWAYS have an adult present. • • ALWAYS wear the correct safety gear while doing any experiment. • • NEVER eat or drink anything while doing any experiment. • • REMEMBER experiments may require marbles, small balls, balloons, and other small parts. Those objects could become a CHOKING HAZARD. Adults are to perform those experiments using these objects. Any child can choke or suffocate on uninflated or broken balloons. Keep uninflated or broken balloons away from children. INGREDIENTS • • Tall Transparent Drinking Glass • • Water • • Eggs • • Pie Pan • • Toilet Paper Tube INSTRUCTIONS STEP 1: Fill the tall transparent drinking glass three-fourths of the way with water. STEP 2: Place the pie pan on top of the tall transparent drinking glass with water. Make sure the pie pan is in the center of the tall transparent drinking glass. STEP 3: Stand the toilet paper tube in the center of the pie pan. STEP 4: Place the egg on the toilet paper tube. STEP 5: Gently hit the pie pan, so the pie pan and toilet paper tube fly out of the way and observe. What happens? Why? STEP 6: Place the pie pan on top of the tall transparent drinking glass with water. Make sure the pie pan is in the center of the tall transparent drinking glass. STEP 7: Stand the toilet paper tube in the center of the pie pan. STEP 8: Place another egg on the toilet paper tube. STEP 9: Hit the pie pan with a greater force, so the pie pan and toilet paper tube fly out of the way and observe. What happens? Why? Compare the effects of gently hitting the pie pan versus hitting the pie pan with a greater force on the motion of the egg. Provide evidence of the effects of balanced and unbalanced forces on the motion of the egg. EXPLANATION When hit with enough force, the egg will fall into the glass with water. As the pie pan and toilet paper tube fly in one direction, the egg resists the change, and gravity pulls the egg into the tall transparent drinking glass with water. **Experiment #2** TURKEY IN A CUP SCIENCE SAFETY PLEASE follow these safety precautions when doing any science experiment. • • ALWAYS have an adult present. • • ALWAYS wear the correct safety gear while doing any experiment. • • NEVER eat or drink anything when performing any experiment. • • REMEMBER experiments may require marbles, small balls, balloons, and other small parts. Those objects could become a CHOKING HAZARD. Adults are to perform those experiments using these objects. Any child can choke or suffocate on uninflated or broken balloons. Keep uninflated or broken balloons away from children. INGREDIENTS • • Plastic Drinking Cup • • String • • Sponge • • Nail • • Pipe Cleaner INSTRUCTIONS STEP 1: Using the nail, push a hole in the bottom of the cup. STEP 2: Thread 3 feet of string, through the hole, in the bottom of the cup, tie a large enough knot, in the string, so the string does not pull through the cup. STEP 3: Holding the cup upside down, wrap a wet piece of sponge, around the string, while squeezing the sponge, pull down in short jerks and observe. Provide evidence that vibrating materials can make sound and that sound can make materials vibrate. STEP 4: Using the illustration of a sound wave, to the right, under “science background,” develop a model of a sound wave with the pipe cleaner. Identify the different parts of the wave. EXPLANATION Sound is vibrations moving through matter. Squeezing and pulling the sponge down the string creates vibrations. The cup amplifies the vibrations allowing you to hear what sounds like a turkey.
