Comparing Plant and Animal Cells Hypothesis: I predict I will see the following organelles when observing a plant and animal cell under a microscope: the cell membrane‚ cell wall‚ nucleus‚ and the endoplasmic reticulum. Frog Blood: Analysis: 1. The shape of the frog blood cell was in a circle‚ or oval. The edges were a little irregular‚ but it could still be identified as‚ basically‚ a circular shape. 2. The cells were produced by an animal‚ a frog. 3. The cell wall was not present

water is clear. A hypothesis is a tentative explanation of the observations. The hypothesis is not necessarily correct‚ but it puts the scientist’s understanding of the observations into a form that can be tested through experimentation. Experiments are then performed to test the validity of the hypothesis. Experiments are observations preferably made under conditions in which the variable of interest is clearly distinguishable from any others. If the experiment shows that the hypothesis is incorrect

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).

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
