Question

experimental design
directions: drag each tile to the correct box.
eddie is going to do an experiment to find out which freezes more easily—distilled water or salt water. in what order should he do the following steps in his experiment?
tiles (blue boxes):

• place both beakers in a freezer and observe which liquid freezes first.
• make a prediction about which liquid will freeze first.
• fill two beakers with 250 ml of distilled water.
• write a report on his findings.
• dissolve 30 grams of salt in one of the beakers.

Explanation:

To determine the correct order of steps for Eddie's experiment, we follow the scientific method:

Step 1: Make a Prediction

Before conducting the experiment, Eddie should hypothesize which liquid (distilled water or salt water) will freeze first.
Tile: Make a prediction about which liquid will freeze first.

Step 2: Prepare the Samples

Next, Eddie needs to prepare the two liquids:

• Fill two beakers with 250 mL of distilled water.
• Dissolve 30 grams of salt in one of the beakers (to create salt water).

Tiles: Fill two beakers with 250 mL of distilled water. → Dissolve 30 grams of salt in one of the beakers.

Step 3: Conduct the Experiment

Place both prepared beakers in a freezer and observe which liquid freezes first.
Tile: Place both beakers in a freezer and observe which liquid freezes first.

Step 4: Report Findings

After observing the results, Eddie should document and report his findings.
Tile: Write a report on his findings.

Final Order (Top to Bottom):

1. Make a prediction about which liquid will freeze first.
2. Fill two beakers with 250 mL of distilled water.
3. Dissolve 30 grams of salt in one of the beakers.
4. Place both beakers in a freezer and observe which liquid freezes first.
5. Write a report on his findings.
