The balloon travels along the string “track.” Pressure from the gases inside the balloon pushes those gases out of the balloon when it is released. As the gases escape from the balloon, they exert a force on the outside air, which in turn exerts an opposing force and pushes the balloon forward.

The more compressed air there is in the balloon, the more force it will have and the faster it will move. If you decrease the number of pumps (lower the air pressure), the balloon has less force and will go slower.

The purpose of this project was to demonstrate how a variable affects the motion of an object. I chose to construct a balloon rocket, testing how different types of string could slow down or speed up its velocity. The independent variable, therefore, was the type of string, and the dependent variable was its velocity.

The escaping air exerts a force on the balloon itself. The balloon pushes back in a manner described by Newton’s Third Law of Motion. A rocket launches when the force of thrust pushing it upwards is greater than the weight force due to gravity downwards. This unbalanced force causes a rocket to accelerate upwards.

Answer: Sometimes, the balls flatten up when you press the clay too hard. You may also have irregular ball shape when the circular motions of your hands are not even.

Answer: if you will press a clay the clay will mold depends what shape or texture that you use. because clay is a stiff, sticky fine-grained earth, typically yellow, red, or bluish-gray in color and often forming an impermeable layer in the soil.

Therefore, the two clay balls will still weigh the same regardless of their shape. This is because a physical change such as flattening will not affect the mass or weights of objects.

Much like the squishy stress ball you pull out from time to time, squeezing play dough is great for helping calm down your anger. Playing with the clay can help ease tension, release excess energy, improve focus, and express emotions.

Answer: : When the strips of clay are pushed from opposite ends then they buckled upwards a little bit which raises the surface a little bit forming like a mountain on the land. Explanation: The pushing of the clay from the contrary sides is an environmental change which results in the development of the plates.

Answer: Clay soils typically undergo changes in volume when the water content is changed. When clay soils are dried,shrinkage and cracking occur. If rewetting occurs subsequent to drying, swelling occurs.

The small size of the particles and their unique crystal structures give clay materials special properties. These properties include: cation exchange capabilities, plastic behaviour when wet, catalytic abilities, swelling behaviour, and low permeability.

There are three essential properties that make clay different from dirt. These are plasticity, porosity, and the ability to vitrify.

All soils contain mineral particles, organic matter, water and air. The combinations of these determine the soil’s properties – its texture, structure, porosity, chemistry and colour.

• color. Soil can be described based on its color (yellow brown red), how light or dark it is, and how intense the color is.
• Texture. Ranges from bolder size pieces to very fine clay.
• Structure.
• Consistency.
• Infiltration.
• Soil moisture.
• Ph.
• Fertility.

Two of the most important properties of soils are their texture and structure . By texture, we mean what soils are composed of and how this affects the way they feel and their cultivation. The main components of soil texture are: sand, silt and clay particles and organic matter.

Soil is generally composed of 50 percent solid material and 50 percent space. About 90 percent of the solid portion of soil is composed of tiny bits of rock and minerals. These solid particles range in size from fine clay to mid-range silt to relatively large, coarse sand.

Soil Texture The particles that make up soil are categorized into three groups by size – sand, silt, and clay. Sand particles are the largest and clay particles the smallest. Most soils are a combination of the three. The relative percentages of sand, silt, and clay are what give soil its texture.
