Science Experiments

The particles are bigger in a suspension, and the solute is not dissolved in the solvent but is dissolved in a solution

suspension example-

sand in water, sand is the solute and water is the solvent

solution example-

sugar in water, sugar is the solute and water is the solvent

The manipulated variable in growing plants could be the type of fertilizer used, the amount of water given, the light exposure, or the temperature of the environment. It is the variable that the researcher purposely changes to observe its effect on plant growth.

The verb of length is lengthen.
Other verbs are lengthens, lengthening and lengthened, depending on the tense.

Some example sentences are:
"We will lengthen your contract".
"This lengthens everything".
"They are lengthening the pole".
"It has been lengthened".

The Hubble Space Telescope is a powerful telescope that orbits Earth and captures images of distant galaxies, stars, and other celestial objects. It has provided significant contributions to our understanding of the universe and has been in operation since 1990.

When light strikes clear glass, most of it is transmitted through the material, allowing you to see through the glass. Some light is also reflected off the surface of the glass. The amount of light that is transmitted versus reflected depends on the angle of incidence and the refractive index of the glass.

first you chill a onion for a day in a fridge. then you cut it and see if your hypothesis was right

They are formed from the solidification of magma below the ground.

The James Webb Space Telescope is an infrared telescope, designed to observe objects in the infrared spectrum. It covers a range of wavelengths from about 0.6 to 28 micrometers.

Some common animals found in Lake Pontchartrain include fish such as redfish, speckled trout, and flounder, as well as birds like pelicans and herons. Other wildlife in the lake may include crabs, shrimp, and various aquatic insects.

Placebos are used in scientific studies to help researchers determine the true effects of a treatment by comparing it to a control group. They provide a baseline for measuring the effectiveness of a new treatment by allowing researchers to account for the placebo effect, which is the phenomenon where a person experiences improvement in their condition simply due to their belief in the treatment.

Yes, an electromagnet can work without a nail. The core material affects the strength of the magnetic field produced, with a nail being a common choice due to its magnetic properties. Other core materials like iron or steel can also be used to create an electromagnet.

It allowed him to see the pathway of protein secretion from the rough ER to the golgi apparatus via vesicles to the nuclear membrane via vesicles, and then out of the cell. He was able to see it by staining radioactive proteins and looking at them at different times after the injection of the radioactive amino acid occured to see where the proteins were.

As the fungal hyphae expand into the orange, they produce enzymes. These enzymes break down different chemicals in the orange. The degraded chemicals are then absorbed by the hyphae to be used as food.

Liquid nitrogen does not impact the density of metals. Density is an intrinsic property of a material and is not affected by the temperature at which the material is in. Liquid nitrogen is often used in materials testing to cool down metals for a variety of reasons, but it does not change their density.

A control group is not provided any treatment, while the experimental group is the one to which a treatment is applied.

The control and experimental groups are chosen to be as similar as possible, so that the observed effect (if any) can be attributed to the variable: what only the experimental group consumes, uses, or participates in.

Cells remain moist in a wet mount, allowing you to see the cell components clearly. Specimens appear in their natural condition. It is possible to observe living and moving organisms. It is also possible to observe certain processes of life, such as feeding and cell division (for water-based mounts).

The rock that can be turned into a diamond is called carbon. Diamonds are formed from carbon molecules that have been subjected to high pressure and temperature deep within the Earth's mantle over millions of years.

Snow can influence humidity levels in the air. As snow melts, it adds moisture to the surrounding environment, thus increasing humidity. Additionally, snow can also impact humidity by reducing the rate of evaporation, which can contribute to higher humidity levels in the area.

It certainly can; people in Europe have been doing it for centuries. It is usually collected in a large barrel rather than a tank - it's always called a water butt.

It is supposed to be used for watering plants during dry spells, but in hard water areas the women have long known that washing your hair in rain-water leaves it softer and shinier than water from the tap.

Some people use a downspout diverter to have option of collecting rain water whenever they want to into a container or to run it normally through a downspout drain extension.

Another way to collect rain water is by using gutters with rain chains attached instead of normal downspouts. Rain chains work best hung from gutters with a few rain chains positioned evenly along the length of guttering. There are small holes or taps made into the gutter and the rain chain hang from these taps. The rain chain can extend to the ground or empty into a basin to collect rain water. Rain chains add a decorative, visually entertaining and even relaxing touch while functioning to direct rain water into your container. Rain chains are best made of copper and allowed to weather naturally.

Water melts faster than juice because juice typically contains sugars and other substances that can lower its freezing point, making it freeze at a slightly lower temperature than water. This means that juice will take longer to reach the temperature where it changes from a solid to a liquid compared to water.

Mineral crystals get their color from the presence of certain chemical impurities or defects in their structure. These impurities can absorb or reflect different wavelengths of light, leading to the perception of color. The specific color of a mineral crystal can be influenced by its chemical composition, atomic structure, and how light interacts with its internal characteristics.

When objects rub together and create friction, the movement generates heat. If the objects have a high electrostatic charge, this can lead to a buildup of electrical energy. When this energy overcomes the resistance of the air between the objects, it can result in a spark, which is a small, visible discharge of electricity.

Graphs can reveal patterns, trends, and relationships in data that might not be evident from simply looking at the raw numbers. They can help to visualize data, identify outliers, and make comparisons between different data sets more easily. Additionally, graphs can provide insights into the distribution and shape of data, as well as aid in detecting any potential correlations or causal relationships.

Ultraviolet telescopes are used to observe celestial objects emitting ultraviolet radiation, which is not visible to the human eye. They provide valuable information about the composition, temperature, and dynamics of stars, galaxies, and other astronomical phenomena that emit UV light. This can help astronomers study the formation of stars, the evolution of galaxies, and the presence of elements in the universe.
