Science Fair Project

I was correct because in the experiment the Duracell batteries lasted 336 hours and 16 minutes. The Energizer

According to article, “In a high-quality program, there is a focus on developing healthy and strong human relationships (p. 40). The program takes place in Condor Elementary School. They used the cafeteria to give them a snack, and make Woven Baskets for children in Protective Services. They had plenty of space to do their project, there were many tables and benches for them to openly do their work, as well as move around. They had a 12-child/2-teacher ratio, which facilitates the supervision of the children. They provided all the material (had plenty of them). They also had board games, plenty of art supplies, and books. In addition, they were provided with outdoor physical activities.

Science is such a unique and highly captivating subject that so many young students find interesting and yet it is also a subject that the vast majority of students get discouraged by as well as lose interest in as they get older. There are so many different areas of science it is easy to be overwhelmed and get discouraged if you easily do not understand something. For this reason, I had decided I need to research a Citizens Science Project that I could bring not only bring into my future classroom but share with my students and their families as well.

The EPA estimates Americans purchase nearly 3 billion batteries each year (D., 2009). A battery is also known as a voltaic cell, and the energy generated and stored by a battery is actually a result of chemical reactions and not mechanical motion. Batteries are contained in nearly every common electronic device, ranging from small devices like smartphones to larger scale products like automobiles, and chemistry is the driving force behind the function of these batteries.Batteries consist of galvanic cells that carry out the production and storage of electrical energy from chemical reactions. The chemical reactions going on inside of the battery are between the oxidant and reductant of Copper and Zinc metals in there Copper-Zinc Voltaic

I do science fair because I love to invent. From designing, to programming and troubleshooting, I enjoy making new things. When I fix a strenuous bug, I feel accomplished. The tougher the bug is, more the satisfaction I get when I resolve it.

My investigative question is does microwaved water stunt plant growth? I was interested in learning more about this topic because I wanted to know if microwaves can put chemicals in your food causing you to not get all of the nutrients from the food. The purpose of my experiment is to see if water set to a boil on the stove, water set to a boil in the microwave, or water from both the microwave and stove will make plants grow more, also to see if the microwave puts bad chemicals into your food. My independent variable is the type of water used. My dependant variable is the height of the plant. My hypothesis is, if plants are grown with microwaved water then they will not grow as much as plants grown with water heated from the stove.

During my visit, I participated in various experiments at the Exploratorium. But out of all of them, the penny battery intrigued me the most. I liked this particular exhibit because I have an enormous interest in electricity. Since it demonstrates properties of conductivity, I was immediately drawn to it.

Traditional batteries are the power source of choice for the Streamlight 69260, and the average battery life is about and hour and 15 minutes of continuous use.

I think that the homemade lipstick is going to be better than the store bought lipstick because you know what you’re putting into your lipstick and there is no added chemicals that can be harmful to you.

I will provide One (1) 9-Volt battery in order for my student to participate in the baby simulation project. Battery is due: ___________________________.

The title of my science project is "Half Baked". My problem was some of the cookie sheets take longer to cook rather than the others. My hypothesis is that I thought that the insulated aluminium cookie sheet would be the most effective in cooking the cookies. My procedure was first, I gathered the materials that I was going to use, next I preheated the oven, Then I observed the cookies and recorded the results and analyed the data and came to a conclusion. I used different types of cookie sheets and set the cookies on for 12 minutes each and recorded how long each cookie took to fully cook. In conclusion the insulated cookie sheet was the most effective and took a shorter time

For those new to Li-Po batteries, they are different from previous battery technologies in that they maintain a nearly full charge right up until they are almost fully depleted, and then they are empty almost immediately. They produce a lot of power, and are prone to thermal runaway (meltdown) when overly depleted, so in addition to buying a quality product, we have a few more words of caution we would like to share with you.

alkaline cells, are available in standard sizes such as AA, C, and D, and they are a fast-moving

In each experimental run, the volume of electrolyte used is always kept to be 150cm3. This is measured using a 250cm3 measuring cylinder

As can be observed the higher the concentration of sulfuric acid means a more charge battery. Lead sulfate concentration increases and sulfuric acid concentration falls as the battery discharges. The same principles are used to construct a normal galvanic cell are used to construct each cell. A microporous separator acts as
