to slow a person‟s fall when jumping from a hot air balloon. Our specific question therefore was: If we change the parachute size‚ how will it affect the time it takes to land? This question allows us to make a prediction (based on a scientific hypothesis)‚ whilst also developing skills such as questioning; measuring and fair testing; recording/interpreting data; drawing conclusions and evaluating results. This investigation links to the national curriculum‟s standard of „Scientific Enquiry‟‚ allowing

Nicholas Pancerella Dino Grow Lab I. Introduction The purpose of this experiment was to see if these toy dinosaurs would grow six times larger than their original size‚ as the package stated‚ if they were soaked in water for four days. My hypothesis for this experiment is that if the dinosaur is soaked in water for four days‚ then the dinosaur would grow six times larger than its original size in all four categories of measurement (mass‚ length‚ volume‚ and width). II. Materials

| |To analyze how competition for resources and limited resources affect population growth. | |2. Make a hypothesis about how you think the two species of Paramecium will grow alone and how they will grow when they are grown together. | | P. aurelia grows faster alone but almost at the same rate when mixed with the caudatum. The P. caudatum

phototrophic movements in plants? Hypothesis: "The direction of sunlight plays an active role regarding phototrophic movements in plants." Prediction: "If a plant is placed in a heliotropic chamber or card board box with a hole on one side and provided with unidirectional sunlight‚ then it exhibits phototropism by growing towards the direction of sunlight." Controlled Experiment and Methods: An experiment is conducted to test the above mentioned hypothesis by using the materials such as two

salt on the lawn/yard is very dangerous‚ especially when the effects really show in the spring time. The effects of rock salt make the yard/lawn get brown and sometimes it dies‚ if not pre-treated with fertilizer or some treatment for plants. Hypothesis: I think that the usage of salt in the winter time affects the growth of grass in the spring time. Prediction: I predict that the grass would grow back slowly or none at all‚ with using salt on them in the winter time because the salt

Drosophila has proven to be very useful tool. Because high alcohol levels has been shown to have an effect of development of the human fetus‚ we asked whether similar effects are observed and to what extent in the Drosophila. In order to test this hypothesis‚ Drosophila were treated with varying levels of alcohol at various times during embryogenesis. Our results demonstrate that as little as 10% alcohol treatme nt has profound effects on Drosophila development. In addition‚ embryogenesis was delayed

allelopathic chemicals (our I.V.) on the germination and growth (our D.V.) on radish seeds. The question proposed became‚ “Does Rose seed extract affect the germination and growth of radish seeds?” Keeping the allelopathic effects in mind‚ our working hypothesis became‚ “If radish seeds get exposed to the rose leaf extract‚ then their percent successful germination and the average length will be less than the percent successful germination and the average length of the radish seeds which do not get exposed

The savannah hypothesis consists of how the apelike ancestors moved from the dark resourceful rainforests to grassy plains‚ where life was a little harder and had to find new ways to obtain nourishment. The need for males to stay away from predators and find food by hunting

The Paper Airplane Lab Purpose: How can a paper airplane be modified so that it can fly farther? Hypothesis: To make our paper airplane fly farther‚ Naveen and I decided to bend the sharp tip of our plane down. We made this modification because the wings of the airplane enable it to fly farther since it makes the airplane stay longer in the air. We believed that because the wings enlarge the volume of the airplane‚ the air resistance on it would become more‚ making it able to stay in the air
