Marble And Viscosity

Procedure: Measure the volume, mass, length and temperature of a variety of items. Create dilution of sugar water.

Conclusion: The results of this lab were found through seemingly simple equations, basing all of your work off of data such as time and distance can become frustrating due to human inaccuracy, but the results show the height and initial velocity of the marble. The results are all reasonable compared with the beginning values that we collected during the lab, and even without calculations fit into the equation. The concept of projectile motion was the basis of this lab, focusing on using kinematic variables and equations to find the

First students obtained 8 graduated cylinders and labeled them. Each one contained a different ratio of vinegar and water. These graduated cylinders with the liquid were weighed and recorded.Then, students obtained an Alka-Seltzer tablet and recorded its mass. Then one alka-seltzer tablet was dropped into each of the graduated cylinders. Students had to

To determine whether the height at which a marble is dropped affect the size of the crater.

In conclusion what makes Oobleck act like both a liquid and a solid? In your mind think that you can see the individual molecules of corn flour and water then think about how they might act when being pushed and pulled. The corn flour and water mixture will act like a solid and a liquid this type of mixture is an example of suspension. The particles stay undissolved in a liquid and corn flour molecules are dispersed into the water. If the cornstarch mixture is pinched, it causes the molecules to go closer together. The effect of the force traps the water between the flour molecules to form a solid shape. When you let go the pressure of your fingers the corn flour will be able to flow like liquid. Viscosity is the resistance for a liquid to

Next, the independent variable was the sail car and shed car. The speed acceleration was the dependent variable. The constants marble distance of photogate the angel of the track.

Snow globes are made of clear glass, a transparent sphere with a scenic view and a plastic toy inside the globe. The globe must be shaken to actuate the snow so the white particles can fall gradually to reach the base. When the marble (object used for this experiment) falls, it experiences two external forces which are; the gravitational force and the aerodynamic (fluid resistance) drag of the marble, which affects the rate of the marble. As the marble is falling, the speed is increased due to the gravitational force, which is pulling the marble downwards to the base of the beaker until it reaches the terminal velocity, where both external forces are equal. However, there are factors that can affect the marble’s terminal velocity, such as

BEFORE CONDUCTING THE EXPERIMENT - You should already have submitted to your teacher an EXCELLENT Investigation Design that included:

When the temperature of the air is increased, it starts to rise. This happens because the hotter the air is, the less dense it becomes. The viscosity in air increases with the temperature; this is equal to the square root of the temperature. The viscosity increases because the molecules collide more frequently. Because of this, the molecules move around randomly, due to the increased number of collisions.

In this experiment osmosis is the main process taking place. Osmosis is the diffusion of water molecules of a solvent which pass through a semi permeable layer and in most cases are due to a concentration gradient meaning that the water molecules travel from an area of low concentration to one of higher concentration. In this investigation, gummy bears of different colours (dependent variable) were placed in different concentrations of glucose (independent variable) over a certain period of time.In addition to that, the color of the gummy bears was also observed to see if the color could

Each time I looked up to the sky I pine for my personal seat/stairs during my tender age. It is located in front of the door on the first floor of my home in city Fuzhou, China.

The experiment showed the flow of substances through the membrane. The pores in the membrane must be small enough to let water, glucose, and IKI to move freely but not enough to let starch pass through.

Temperature affects lava flow by increasing or decreasing the viscosity, therefore affecting the speed at which the lava flows. In the graph presented, the visual data clearly shows that as the temperature of the syrup rises, the velocity increases. The overall average velocity for all the groups who used cold syrup was 1.34 cm/s. The overall average velocity for the groups who used room temperature syrup was 4.43 cm/s, and the overall average velocity for the hot syrup groups was 6.82 cm/s. This is because, like most liquids, syrup (and lava) has molecules inside that move around more freely when the liquid is in a form where the temperature is hotter. On the other hand, a colder temperature may make molecules move less, and the decrease in

In this experiment, three variable flow meters are used to alter the flowrate. Changes in pressure drop due to the change in flowrate are then observed from the three pressure gauges that can measure pressure at different range and recorded. The shift from laminar flow to turbulent flow is seen from the results recorded, but it is observed more clearly from the water-soluble dye experiment that was carried out by the demonstrator. Laminar flow turns to be turbulent when the Reynolds Number goes above a certain value, around 2000.
