Would a 20lb bowling ball weigh more than a 3-foot cube of styrofoam?
Yes and no: the ball would weigh more (yes) but they don't make balls that big (no).
What are ways that will make a plasticine float on water?
To make plasticine float on water, you can try shaping it into a boat or a hollow structure that traps air inside. The trapped air decreases the density of the plasticine, allowing it to float. You can also use a larger piece of plasticine to displace more water, increasing its buoyancy.
Five ways how to make a plasticine float?
Increase its volume by adding more plasticine. Shape it into a hollow, buoyant structure like a boat or raft. Use a light material, like a small piece of foam, to help it float. Mold the plasticine into a ball shape, which can displace water and float. Create an air pocket within the plasticine to increase its buoyancy.
Is sand heavier than Styrofoam?
Yes, sand is generally heavier than Styrofoam. Sand has a much higher density, meaning it is more compact and contains more mass in a given volume compared to Styrofoam, which is a lightweight material made from expanded polystyrene. Consequently, if you compare equal volumes of both materials, sand will weigh significantly more than Styrofoam.

Which is more brittle plasticine or glass?
Glass is more brittle than plasticine. Plasticine is a soft, flexible material that can be easily manipulated and shaped, whereas glass is a hard, rigid material that shatters into sharp pieces when broken.
Why plasticine sinks in water?
Plasticine sinks in water because it is denser than water. The material used to make plasticine is heavier than water molecules, so it displaces water and sinks to the bottom.
Which weighs more 10kg stack of books or 10kg piece of Styrofoam?
Both the 10kg stack of books and the 10kg piece of Styrofoam weigh the same amount, 10kg, because weight is a measure of the force due to gravity acting on an object's mass.
How would you find the density of plasticine?
Roll the plasticine into a sphere and measure the diameter and use the formula for the volume of a sphere V=pi r^2, then weight the sphere to get the mass and use Density = Volume upon Mass. Alternatively, use Archimedes' principle: 1) Weigh a piece of plasticine to get its mass. Very carefully fill a glass with water so full that it cannot contain one more drop of water. Immerse the plasticine in the glass, collecting the water that has run out of the full glass. The volume of the water is equal to the volume of the plasticine. Determine the volume of the water by either weighing it (density of pure water is 1 g per mL) or by accurately measuring the volume. Density = mass (g)/ volume (mL) 2) If you have a balance that can determine mass of an hanging object, first weigh your plasticine to determine its mass. Then attach it to string and take its mass hanging (the string also has mass). Then take its mass while the plasticine is just submersed in water. It will weigh less when submersed in water. The loss of mass when submersed is equal to the mass of water that has the same volume as the plasticine. (density of water is 1 g per mL) Now you can determine the volume of the plasticine since the mass lost in g equals the volume of water in mL. Density is the original mass divided by the volume.
How do you make styrofoam decompose?
Styrofoam does not easily decompose in the environment due to its chemical composition. However, there are technologies being developed that use bacteria or enzymes to break down styrofoam into more eco-friendly compounds. Recycling or proper disposal of styrofoam is important to reduce its negative impact on the environment.
Can you stick plasticine to canvas?
Yes, you can stick plasticine to canvas, but it may not adhere very well over time. Plasticine is designed to be malleable and won't bond permanently to surfaces like canvas. For a more secure attachment, you might consider using an adhesive specifically designed for art projects, though this could alter the plasticine's texture and appearance. Additionally, the weight of the plasticine could affect the canvas over time.
Does Styrofoam absorb sound?
Styrofoam does absorb sound but it reflects it also. It absorbs more than a brick wall but not as much as softer foams. It does make very good heat insulation.
