Suppose you have 7 pieces of wood shown to the right. Predict what will happen to the mass of the pieces of wood if you put them together without cutting them to make a birdhouse

Ever heard of the law of conservation of mass?

Think about it.

what is wrong with teachers now days

you have 7 pieces of wood shown to the right. Predict what will happen to the mass of the pieces of wood if you put them together without cutting them to make a birdhouse

One big bird nest

They would take the shape of a birdhouse

They would form a birdhouse

To predict what will happen to the mass of the pieces of wood when they are put together to make a birdhouse, you need to consider the properties of wood and how they behave when combined.

1. Determine the mass of each piece of wood: Use a weighing scale or a balance to measure the mass of each individual piece of wood. Make sure you record the mass of each piece accurately in grams or any other appropriate unit.

2. Calculate the total mass of the individual pieces of wood: Add up the masses of all seven pieces of wood to get the total mass. For example, if each piece weighs 100 grams, the total mass would be 7 x 100 grams = 700 grams.

3. Consider the conservation of mass: In general, when you combine objects or materials, the mass of the resulting object should be equal to the sum of the masses of the individual components, assuming no mass is lost or gained during the process.

4. Estimate the mass of the final birdhouse: Since wood is tightly joined together to form a birdhouse without any loss or gain of mass, the total mass of the birdhouse should be the same as the previous total mass of the individual pieces of wood. Therefore, if the total mass of the pieces of wood was 700 grams, the mass of the birdhouse should also be 700 grams.

In conclusion, when you put together the 7 pieces of wood to make a birdhouse without cutting them, the mass of the birdhouse should be equal to the total mass of the individual pieces of wood, assuming no mass is lost or gained during the construction process.
