Can anyone help with this? Thank you!

Question: 4. Variables that Influence the Buoyant Force Materials: Two small metal blocks of different mass, but the same volume. Small beaker or cup, small pellets (or rice or lentils) to add as weight. Larger container to fill with water. Tall container. Two metal blocks of the same material. Salt solution. 4.1 Mass How did the buoyant forces compare for two blocks submerged in water when the two blocks have different masses but equal volume (e.g., aluminum and iron)? 4.4 Density of object Predict how the buoyant forces would compare for two objects of the same density but different sizes (e.g., the single and double aluminum blocks). 4.2 Volume Predict how the buoyant forces would compare for two objects of different volumes, but equal mass 4.5 Density of fluid submerged in water. Saltwater is more dense than regular. Predict whether the buoyant force on an object submerged in salt water is greater than, less than, or equal to the buoyant force on the same object submerged in (pure) water. 4.3 Depth Predict how the buoyant forces would compare for two identical blocks submerged at different depths (e.g., just below the surface and near, but not touching, the bottom)
