Materials required for this science project are: The fruit flies were put to sleep, using triethylamine, so that the males could be clearly distinguished from the females. Five male fruit flies were then place into each of the four vials. Four groups were created by varying the food mix. The control group's food mix contained only water - [Read more]

Science project idea that investigates the question: Does the pH of water in which a tadpole is placed affect its life span? Methodology, analysis, summary and conclusion and relevant application of data are all presented of the experiment. - [Read more]

Experiment will allow you to use the fruit fly Drosophila melanogaster to do genetic crosses. You will learn how to collect and manipulate fruit flies, collect data from F1 and F2 generations, and analyze the results from a monohybrid, dihybrid or sex link cross. - [Read more]

Science project idea where you will investigate the movement of water across semi-permeable membranes. You will also examine the effect of solute concentrations on water potential as it relates to living plant tissues. - [Read more]

Science project idea which will allow you to measure the rate of a reaction in the presence and absence of a catalyst. The catalyst, (catalase), is an enzyme in cells that catalyzes the breakdown of toxic H202. - [Read more]

Science project idea where you will study plant mitosis using prepared slides of onion root tips and will calculate the relative period of the phases of mitosis in the meristem of root tissue. You will also study the crossing over and recombination that occurs during meiosis. - [Read more]

Science project idea where you will separate plant pigments using paper chromatography. You will also measure the rate of photosynthesis in isolated chloroplasts using a measurement technique that involves the reduction of the dye, DPIP. The transfer of electrons during the light-dependent reactions of photosynthesis reduces DPIP and changes its color from blue to colorless. - [Read more]

Science project idea where you will measure oxygen consumption during respiration as a change in gas volume in germinating and nongerminating peas at two different temperatures. - [Read more]

Science project idea where you will investigate some basic principles of genetic engineering. Plasmids containing specific fragments of foreign DNA will be used to transform E. coli cells, conferring antibiotic (ampicillin) resistance and the Lac + phenotype (ability to metabolize lactose). Restriction enzyme digests of phage lambda DNA will also be used to demonstrate techniques for separating and identifying DNA fragments using gel electrophoresis. - [Read more]

Science project idea where you will learn about Hardy-Weinberg law of genetic equilibrium and study the relationship between evolution and changes in allele frequency by using your class as a sample population. - [Read more]

Science project idea where you will apply what you learned about water potential from Diffusion and Osmosis to the movement of water within the plant. You will study the organization of the plant stem as it relates to these processes by observing sections of fresh tissue. - [Read more]

Science project idea where you will learn how to measure blood pressure and measure pulse rate under different physiological conditions: standing, reclining, after the baroreceptor reflex, and during and immediately after exercise. The blood pressure and pulse rate will be analyzed and related to a relative fitness index. You will also measure the effect of temperature on the heart rate of the Daphnia magna, and calculate a Q10 for the relationship between temperature and heart rate. - [Read more]

Science project idea where you will examine the habitat preferences of the brine shrimp, Artemia. You will use controlled experimentation to determine the thermal, pH, and light environments selected by Artemia. Based on your experience with this lab, you will design an experiment that could be used to survey other variables and other organisms. - [Read more]

Science project idea on how you will measure and analyze the dissolved oxygen concentration in water samples using the Winkler technique. You will also measure and analyze the primary productivity of natural waters or lab cultures - [Read more]

Science project idea on how to gain weight. Experiment has information on: Purpose, Hypothesis, Materials and Procedure. - [Read more]

Science project idea testing the memory of bad taste in mice. The chemical Lithium chloride is used to make food taste bad for the mice. - [Read more]

Science project idea to see if an animal's sleep habit can be altered by artificial light. Procedure includes measuring their sleeping activity during the day and during the night. - [Read more]

Science project idea on the knowledge of students about endangered and extinct animals using a survey approach. Experiment includes: Purpose, Hypothesis, Methodology, Analysis of Data, Summary and Conclusion and Analysis of Data. - [Read more]
