The rocket I produced was a normal looking rocket compared to the group of rockets I was working with. It was medium size in length and thickness. The head of the rocket was a little wide and lose, and the flaps were not arrow dynamic what so ever. To improve the flight I could have made my rocket shorter and thinner because the smaller the mass the greater acceleration. Doing this would improve the acceleration of the projectile in this case the rocket. Also to improve the acceleration I could add more alka-seltzer to the film case. Doing this would add a greater force to push off of which would make the rocket go higher and faster. Lastly I could have made the structure for the rocket more aerodynamic. To do this I would make the flaps triangles that do not stick out. Doing that will let…
(1) Limescale is the deposits left behind by hard water. Limescale is mainly made up of calcium and magnesium. We advise you not to use acetic acid-based descaler (vinegar), as this could have a negative effect on the taste of the coffee.…
What I learned about bottle rockets is the smaller the bottles, the higher the rocket goes. The rocket has to have water on the bottom for it to fly. What I did for my rocket is I got two 2 liter bottles. I cut part of the bottom off one of the bottles and taped them together. But, you have to make sure it’s not sideways. If the bottles are taped on sideways if won’t fly straight. Then, I cut out four fins and glued them on the bottom of the rocket. With the fins there is a better chance it with fly higher. Next, I cut out five strings for the parachute. We put a parachute on it so that when it comes down the parachute will slow it down for it not to hit the ground hard. For the parachute I got a plastic bag and taped the strings to it…

First you'll need some inexpensive items to make your homemade Play-doh starting with Newspaper, medium size bowl, a spoon, 1/2 cup of salt, 1/2 cup of water, 1 cup of flour, and a food dye coloring. To start layer your working surface with newspaper just so you don't make a mess of the area you will be using to make your Play-doh. Next measure out a cup of flour 1/2 cup of salt and 1/2 cup of water take your medium size bowl and pour into the bowl your ingredients such as the 1 cup of flour and 1/2 cup of salt and water that you have just measured out. In addition to all the ingredients in your bowl take the spoon you need and mix your mold until it appears mushy and is no longer watery nor flourly this should only take about a few minutes. Then add 5 to 10 drops of the food coloring of your choice to your mushy mold of dough. Then start kneading it until your color is fully distributed throughout your new Play-Doh, if your unhappy with lightness of color you can put in…
* To construct my project, I first began building the protection chamber for the egg. I glued 4 or 5 sections of paper together to make it sturdy and safe. I made a flap that tucked in so that the egg could not fall out. I then glued more paper together in the shape of a box. There was a base and a lid, sort of like a Christmas present. I put straws around the metal of the axle and glued them onto 4 pieces of straws glued to together. All that was left after that was to glue the box onto the straws connecting the wheels. I then filled it with some scraps of paper so the protection chamber could not move around.…
The activity helped the children to investigate because they had never seen a reaction before and they were interested about what was going to happen. The children had a hand on approach by putting the vinegar into the milk; they also smelt the vinegar beforehand. To make the plastic colourful, I got the children to add glitter and food colouring. After I mixed together all of the components as the milk was hot the plastic was formed, after…

Bottle rockets, people see them as middle school science projects where kids have fun and build little rockets. Actually there is a lot behind bottle rockets, it’s more than just throw some plastic bottle together and glue some wings to it and fly it. The researcher chose this topic because in his class they are doing the bottle rocket project and he wanted to find out which rocket was more efficient for hang time. So the experimenter built some rockets and launched them and gathered the results. In this paper there is some history of rocketry which the researcher used to design his rockets. The results are also contained in this paper; they show how different dimensions of water rockets affect its hang time. The way the researcher built the rockets was fairly simple he first used a 2-liter bottle as the base, then he cut another bottle in half and taped it to the bottom of the base bottle, after he attached a plastic cup to the half bottle, and finally he taped the top half of a small Coke bottle. After launching and gathering his data he came to the conclusion that his hypothesis was right long rockets with medium size fins preformed the best and had and average hang time of 7.16 sec. Other rockets performed well but they did not have the greatest hang time of all the launches. The conditions were equal for all rockets so the hang time was not affected by other variables.…
The process of constructing the catapult was not challenging because it consisted of simply hot gluing popsicle sticks together to create the structure. However, the most difficult part about building the catapult was the attachment of the spoon with rubber bands, which was then attached to…
Sodalite walked slowly through the stream in the forest, pumping her legs through the cold, yet somehow warm water. The current of the stream wasnt very rough, so it was (sort of) easy to trudge through the crystal clear water. Sodalite sighed, reminiscing on how she came to Earth. She wasnt from this planet, for she was actually from homeworld. She was to be shattered because she was ‘wrong’; but it wasnt even her fault. Soda was blind in her left eye due to her lazy kindergarteners. They placed her hole near a sharp, jagged rock that even the kindergarteners knew that it would compromise the gems’ growth. But they placed the injector there anyway, and now she was stuck like this. Soda cracked her fingers and looked at the position of the…
You breathe in the gas and air through a mask or mouthpiece, which you hold yourself. You'll probably practise using the mask or mouthpiece if you go to an antenatal class. The gas takes about 15 to 20 seconds to work, so you breathe it in just as a contraction begins. It works best if you take slow, deep breaths.…
