Parachute Experiment Aim: To investigate the effect of surface area on a performance (more the amount of a parachute better the performance) of a parachute. Hypothesis- More the amount of holes in a parachute‚ faster the rate of the fall. Variables: Dependent variable- The time it takes for the parachute to reach the ground. Control variables:Mass > Adding or subtracting mass from the load. > Clay can be molded around the load to increase mass. > Parts of the load can be cut off to decrease the

Problem Statement To determine how effective a container is‚ in adequately storing chocolate and how innovative the use of the package will be. Trigonometry Pythagoras Theorem and Calculus is used to determine: 1) The max cross sectional area of the pentagonal prism 2) The minimum value of the contents 3) Amount material needed for packaging 4) The minimum number of containers in order to make a profit

unit conversion. In this lab we measured the dimensions of a wooden block using a ruler and Vernier calipers‚ we also measured its mass using an electronic scale. We used all the measurements to calculate other properties of the block‚ such as its surface area‚ volume‚ and density. (89 words) Introduction: There is a huge difference between measuring a distance to be 10 cm using a ruler‚ using a caliper‚ and using a laser. A ruler can only measure distances reliably down to 1 mm. A set of calipers

AIMS The aim of this experiment was to investigate the effect of temperature rise on the rate of transpiration of a plant (hibiscus) by measuring the plant’s water uptake in a period of time. HYPOTHESIS Transpiration is the process by which plants loses water to the atmosphere from their leaves. Water in the plant is lost to the atmosphere by evaporation. Evaporation of water can occur at any temperature. In the presence of sunlight‚ water in the plants evaporates into the intercellular air

In the middle of that area is a hole‚ which can be described as a tunnel. Between the two ends‚ there is a loop that’s connected to both sides.
