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

13‚ 2012 Needle through a Balloon Pre-Lab Preparations: Purpose: The purpose of this experiment is to see if the balloon pops when pierced with a wooden skewer or a sharp pin. Hypothesis: If we lubricate the skewer with petroleum jelly‚ then it should go through the balloon without popping. Hypothesis for the 2nd part of the Lab: If we cover the side of the balloon with cellophane tape‚ then it will not pop when pierced with the pin. Materials: • Balloons • Long wooden skewer •

different pepsin concentrations (0%‚ 0.2%‚ 0.4%‚ 0.6%‚ 0.8%‚ 1.0%) shows‚ as the egg white is a protein and the pepsin works as an enzyme‚ how a higher pepsin concentration and therefore a larger amount of enzymes effect the rate of reaction. Hypothesis: An increased concentration of pepsin speeds up the time the mixture needs to come clear. Introduction: The egg white is our protein solution‚ because egg white is a typical protein with peptide bonds between its amino acids that can be broken

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

I. 6. Hypothesis - a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation. 7. Empirical data - Empirical evidence (also empirical data‚ sense experience‚ empirical knowledge‚ or the a posteriori) is a source of knowledge acquired by means of observation or experimentation. The term comes from the Greek word for experience‚ Εμπειρία (empeiría). 8. Review of related literature - A review of related literature is the process of collecting

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

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).
