The reason I joined this 2 1P's together, is the same reason as the 1P2 & 1P3. In fact, this 2 worksheets are 2 parts.
In 1P4, there were many segments. Firstly, we poured vinegar into a test tube and added sodium bicarbonate. The vinegar reacted to the sodium bicarbonate and it bubbled, we poured the thing into the sink and the bubble got stuck at the hole. We poked it with the thing used to clean test-tubes. Next, we were to place a drop of methlylated spirits onto the back of my hand and blow it. It became freezing cold and my hand felt numb. Suck a nice feeling, it felt cool at the same time disgusting. Next, we filled a beaker with limewater then we blew into it. The limewater turned chalky as it reacts in with the Carbon Dioxide in the air we exhaled. Next, we put a few drops of iodine solution, the starch turned dark-blue as it reacted with the iodine.
We were to draw a alien spotted in and outer-space excursion. The alien I drew looked so ugly and silly, then we were to write whether the clue was an inference or an observant, it was pretty easy.

Finally, in 1P5, we were to heat a beaker of water and checked the temperature every minute, the water increased very unstably until the water boiled, I was surprised when the water increased to 101'C (:D). Then I found out that it was not pure water. Then we were to plot a graph to draw the increase in temperature as we learned the independent and dependent axis.
