appear vertical. This nearly vertical position is called the “charge neutral” position. Rub a rod provided for you with fur and bring the rod near the top of the electroscope without touching it. The electroscope needle should move. Keeping the rod in place‚ hold the charging plate with your thumb and fingers. Remove the rod and your hand. The needle should be in the same position as when you had only the rod there. This is called “permanently charged”. Touch your fingers to the plate

That was lucky. Every fisherman has their luck

In this experiment‚ we will be investigating what stimulates action potential on the nerve being tested on the oscillator. The factors that helped determine action potential are voltage‚ single stimulus‚ Hydrochloric acid‚ sodium chloride‚ the glass rod‚ and heat. II. Activity 8: Nerve Conduction Velocity • In this activity‚ we will be investigating action potential like in activities 1-4‚ and the nerve conduction velocity. We will test an earthworm nerve‚ frog nerve‚ and two rat nerves on the

fountain design is aesthetically appealing but may be vandalised. The Chinese cups may be chipped or broken if hit with a hammer or metal bat. To avoid this from occurring‚ the cups will be constructed out of thick concrete and secured to the steel rod by steel collars‚ which attach to the lip of the cups/bowls. The water pump and filtration may present an issue down the track because the u-shaped sandstone structure has a copper water pipe inserted inside it to allow the water to circulate. The
