1) Demonstrate understanding of the terms atom and molecule. Atom= Smallest Unit of Matter Molecule= 2 or more atoms chemically bonded. 2) Describe paper chromatography. 3) Interpret simple chromatograms. A method used to separate a Solution‚ using a Paper and a beaker of water. The Substances in the Paper go up depending on their Mass. We can say that a Solution has the same substance as another solution because they form a line of the same height. 4) Describe methods of separation

1. What are the six regions of the Sun? The Sun’s regions are the core‚ the radiative zone‚ the convective zone‚ the visible surface‚ the chromospheres‚ and the corona. The core‚ radiative zone‚ and convective zone make up the interior of the Sun. The visible surface‚ chromosphere‚ and corona make up the exterior of the Sun. 2. What is nuclear fusion? What role does nuclear fusion play in the Sun? Nuclear fusion happens when two atomic nuclei combine to form one heavier nucleus. Since the majority

Some cars are powered by gasoline‚ diesel‚ or other combustible fuels‚ or you can even power miniature race cars using a mousetrap! In the Balloon Powered Car‚ we’ll show you how to build a racer that uses the power of air pressure to roll across a room. Objectives: a.) to create a balloon powered race car for maximum speed and distance

its dormant state‚ the balloon’s circumference and weight will increase‚ the pH will decrease‚ and the process of cellular respiration will be replaced by fermentation. Parts of the hypothesis were supported while others parts were disproved. The balloons’ circumferences‚ cellular respiration being replaced by fermentation‚ and forearm muscle fatigue were supported by the data. However‚

reaction where matter is forced together and the nuclei are fused together. This is how the first start was born when hydrogen atoms were fussed together to create helium. After this many more starts and a lot more elements were created. Stars start there life as a cloud of gas called a nebula. Mainly consisting of hydrogen and helium. The gases will then be drawn to a centre point of gravity which will then create a protostar. And then the nuclear fusion in the core of the star will star and the

goal of the machine would be to pop a balloon and to blow out a candle. The goal would be achieved by using the potential energy in the balloon‚ popping it‚ and using the now present kinetic energy‚ which is the air‚ to blow out the flame of the candle. The final products would be a popped balloon and a blown out candle. The trial of planning and building the alka seltzer project was very chaotic. Initially‚ the goal of the machine would be to pop a balloon and chemically change the color of a liquid

using classical conditioning as well. SLIDE2 GLOBOPHOBIA: DEVELOPING A FEAR OF BALLOONS BEFORE CONDITIONING Loud Noise = unconditioned stimulus (US) - Crying/Fear = unconditioned response (UR) Balloon = neutral stimulus (NS) – no response (NR) DURING CONDITIONING Popping balloon (UCS + NS) = Crying/Fear (CR) AFTER CONDITIONING Balloon (CS) = Fear/Crying/Phobia (CR) (Speaker Notes) Globophobia is the fear of balloons. As with most fears‚ globophobia is most likely a result of classical conditioning

had to do was to fill 5 balloons to the same volume with different gases and to raise the temperature. From this experiment came Charles’ Law. The law that affects everything from footballs to the human lungs. Jacques Charles is very important to today’s scientific studies because of what he invented‚ his achievements‚ and his studies on volume and temperature. Jacques Charles was born Beaugency‚ France in 1746. He was a French balloonist who flew the first hydrogen balloon in 1783. With the help
