Scientists created a model to predict the path of a snowstorm. However, the storm moved in a different direction than expected. What is the most likely reason for this?

• The weather station changed the storm’s direction on purpose

• The model was made without using any data

• Scientists ignored satellite images when creating the model

• Natural events can change quickly, and models can't predict everything perfectly

Leah dropped her necklace beads into a container of sand. What is the best way she could quickly separate the beads from the sand?

• Heat the sand until it turns into glass

• Pour the sand and beads through a sieve

• Add water to dissolve the sand

• Shake the container and hope the beads rise to the top

During a science experiment, Jackson placed a metal spoon in a cup of hot tea. After a few minutes, the spoon felt warm. What is the best explanation for why the spoon became warm?

• The cold from the spoon moved into the tea, cooling it down

• The heat from the tea caused the spoon’s molecules to slow down and clump together

• The heat from the tea caused the spoon’s molecules to speed up and spread apart

• The spoon absorbed water, which made it feel warmer

Eli built a simple circuit with a battery, wires, and a light bulb. However, the bulb is not lighting up. He notices that one of the wires is not connected. What should he do to make the light bulb turn on?

• Connect the loose wire to complete the path

• Remove the battery from the circuit

• Replace the light bulb with a larger one

• Add a second battery to increase the voltage

Why is it important to be careful around exposed electrical wires?

• Wires can be too small to see clearly.

• Electricity makes wires too hot to touch.

• Wires are often used to connect TVs and computers.

• The human body can conduct electricity, which can cause harm.

Maria wrapped a wire around a large nail and connected the ends of the wire to a battery. When she brought the nail near paperclips, they stuck to it. What is the most likely reason this happened?

• The wire got hot and melted the paperclips

• The nail created a magnetic field when electricity flowed through the wire

• The battery gave off light that attracted the paperclips

• The paperclips made the battery stronger
