Cut a 7-inch-diameter circle out of card stock. Draw a spiral on the circle as shown. Next, use the scissors to cut along the lines you drew starting on the outside and ending in the center. Use the hole punch or scissors to make a hole at the middle of the spiral and attach the thread with a knot. Tie the other end of the thread loosely around the center of the stick so you can suspend the spiral in the air. Fill the pot with 2 inches of water. Heat the water until it boils, and then turn off the heat source. Let the pot sit for 4 minutes. Holding the ends of the stick with the spiral attached, position the bottom of the spiral right above the top of the pot so it’s not touching the water. Describe what happens.

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit
