And that way is an air pump for footballs. Jim airs up Tim and Tim airs up Jim as they count to three they pop off and start flying through the air. In a short twenty minutes they are at the commissioner’s office. They bring to the attention of the commissioner that they could get hurt but the commissioner doesn’t let them

Effect of all-natural bath and body wash on millet seed growth. This experiment was conducted to determine what effect a household chemical would have on the growth of a plant. Everyday multitudes of chemicals are washed down the drains inside of our homes; many of these same chemicals are then being introduced into the environment through our water sources‚ such as rivers. This experiment will test the effect of all-natural bath and shower gel would have on the growth cycle of millet seeds. The

Purpose: How will salt and plain water affect plant cells? Hypothesis Clear water: If you place carrots and celery in plain water they will become flaccid and then eventually start to loose its colour and pieces of the celery or carrots will fall off. I know this because the vegetables will continue absorbing water putting the vegetable in a hypotonic solution. Pieces of the vegetable could break off because the cells are not getting what they need. The cells need to create glucose and oxygen

and has caused various devastations to the ecosystem. Pollution is the presence of contaminants into the environment which causes instability‚ harm or discomfort to the Environment. Pollution can take the form of chemical substances or energy (noise‚ heat‚ and light). The causes of pollution can be classified into two types - man-made pollution and natural pollution. Natural pollution does not have a big impact on the quality of life since it has a balanced regenerated ability. On the other hand‚

Salt and the effect it has on water. Do you like salt? Do you put it on your food to make it taste better? Salt doesn’t just make food taste better; it can change the freezing and boiling point of water. I bet you didn’t know that! There’s a reason for that‚ but I’ll explain that a little later. First‚ let’s find out if salt can actually change the freezing and boiling point of water. To do so‚ we need to do an experiment. Now‚ if you’re going to do an experiment‚ you’re going to need a hypothesis

Fundamental Science Salt water egg experiment Result Some objects float on top of the ocean‚ and other objects sink to the bottom. Why? In this salt water egg experiment we can find a solution for this question. It was noted that to make the egg float salt is needed to dissolve into fresh water. When the egg was lowered into the fresh water container it started to sink. But when salt was added to the container the egg started to float. Adding salt to the water squishes more molecules

Aim: Perform an experiment to determine the latent heat of fusion for milk. Materials: Calorimeter Celsius Thermometer Platform balance Kettle Milk ice cubes Stopwatch Hot Water Procedure: The copper cup was weighed and its mass was then recorded. The kettle was then used to boil water and this water was poured into the copper cup. The mass of the cup plus the hot water was calculated and recorded. The copper cup was then placed in the insulated container. The water’s temperature was

Water Rockets Abstract Water rockets have been a source of entertainment and education for many years. They are usually made with an empty 2-litre PET bottle by adding water and pressurizing it with air for launching. Water rockets are used to help students understand the principle of aeronautics. Aim The aim was to design and perform an experiment to determine the volume of water to use in order to obtain maximum height for the bottle rocket. Introduction Bottle rockets are often used in
