Worksheet time: 3hrs 30mins
Students gathered the following materials. What are the students trying to investigate?
The students are trying to construct a circuit to investigate the conductivity of electricity.
The students are investigating whether the materials dissolve in water.
The students are investigating whether the objects will change states.
The students are constructing a circuit to investigate the density of the materials.
The diagram below shows a mixture of salt and water. After the students mixed the salt, it dissolved in the water and created a new substance. How can the students separate this new substance?
Use filter paper, the water will flow and the salt will stay on the filter paper.
Use a hot plate, the water will boil and become water vapor while the salt stays behind on the beaker.
Use a sieve, the sieve will hold the salt while the water flows to the beaker.
Wait for the salt to separate from the water after 20 minutes because salt is less dense than water.
The students are conducting an investigation. They have gathered the following materials and placed their observations below. Which physical property of matter are the students investigating?
Density because only the iron nail is more dense than water
Conductors of electricity because yarn, plastic straws, and copper wires do not allow electricity to flow.
States of matter because all the materials are solid.
Magnetism because copper wires, yarn, and plastic straws are not magnetic.
Students measured 100 ml of water and poured it inside a beaker. The teacher then asked the students to place 50 ml of water in the freezer and 50 ml of water in a hot plate for 20 minutes. What did the students most likely observe after 20 minutes?
The water in the freezer became a solid while the water on the hotplate had evaporated.
The water in the freezer stayed a liquid, while the water on the hotplate was boiling.
The water in the freezer “disappeared: while the water in the hotplate stayed a liquid.
Both the water in the freezer and the hotplate keep the same state of matter.
The picture below shows a balanced scale using a box and ping pong balls. Students are investigating using this pan balance. What are they trying to measure?
Volume of the mystery box compared to the ping pong balls.
The size of the box compared to the ping pong balls.
The density of the box and the ping pong balls.
The mass of the mystery box compared to the ping pong balls.
