Everything except the comb was made of ¼ inch Acrylic Plexiglass. The glass helped the group see what was going on in the experiment. The comb was 3D printed to be more accurate. One material was a casting tray which held the Gel in future steps.

because blue light has a higher absorbance by plant photosynthetic pigments and has a higher energy wavelength than red light‚ we predicted that juniper needles placed in blue light would photosynthesize faster than juniper needles placed in red light. We measured the rate of change in CO2 concentration due to juniper needles. For each sample‚ we placed the needles into a chamber connected to the CO2 monitor and measured the rate of change of CO2 concentration for 10 minutes under red light and then

Light Transmission Through Liquids With Different Viscosities Introduction Aim This experiment investigates the effects of different liquid viscosities on light transmission. The results of this experiment could greatly benefit marine biologists or other marine scientists. This would help them figure out how their flashlights would work in different water conditions in the ocean. Background Research Spectrophotometers are devices that measure the amount of light absorbed by a certain liquid

Effect of seed germination Purpose: To see the effect of an acid introduced during seed germination‚ on the length of the plant roots. Also shows how salt can affect the seed germination. Acid can be introduced to seeds during germination if there is acid rain. Knowing the results of acid rain on seed germination will help us understand how to grow pants better‚ and how to have more successful germination. Salt can be introduced into a seed during germination because salt is put on roads and the

Factors Affecting Seed Germination Research Question What is the effect of dark and light on the germination of radish seeds? Hypothesis I predict the seeds grown in the light will germinate twice as much as the ones grown in the dark. Materials/Setup Paper towels 2 petri dishes 10 radish seeds Water Plastic container A weight A folded piece of paper Procedure 1. Take a paper towel and cut out two circles that are the same size as the base of the petri dishes. 2. Wet

Radish Radishes are only moderately cold hardy and need about 6 weeks of favorable growing conditions to produce sufficient biomass to achieve most potential benefits. Lastly‚ be forewarned that rotting radish residues produce a powerful rotten egg-like odor‚ particularly during winter thaws. Radish Seedlings and Sprouts Radish seeds don’t have to be planted‚ they can be grown in a sprouter and eaten just as you would eat mustard and cress or any other sprouted bean or seed. As some of my

BIOL 1401 General Biology Laboratory Seed Germination Exercise Introduction Seeds are produced by the more advanced plant groups that we will study this semester – Gymnosperms and Angiosperms‚ which are grouped as seeded-vascular plants. While we often take seeds for granted‚ they are remarkable in their physiologies and very diverse in their structure and germination requirements. Seed biology is actually a separate sub-discipline in botany‚ with direct significance to the study of plant ecology

temperature affect radish germination. The original hypothesis was if temperature affects the tail length of the germinated seed‚ then a higher temperature will lead to a significant decrease in the tail length of the germinated seed. This hypothesis is true‚ according to the collected data. After 6 days of letting the seeds germinate‚ the ones that germinated in room temperature were quicker to germinate and with a lot more tail length compared to the ones in the incubator. In fact‚ the seeds from the incubator
