In the thrilling world of plant investigations, what should Hannah, guided by her friend Mason, correct in her experiment?

• She should plant different numbers of plants in each bottle.

• She should vary the sizes of the bottles.

• She should place different quantities of soil in each bottle.

• She should add different amounts of water in each bottle.

Join Abigail, Emma, and Jackson on a thrilling adventure to uncover the secrets of erosion! They're on a mission to discover how different types of soil affect erosion on a hillside. They've built a model of a hill and are ready to let the water flow!

What's the best way for them to design this experiment as a fair test?

• Change the slope of the hill in each trial.

• Change the type of soil on the hill, and conduct multiple trials with each soil type.

• Change the amount of soil on the hill and the slope of the hill in each trial

• Change the amount of water that drips on the slope, and conduct multiple trials

Hey there, young scientist! Ethan and Ava are conducting an experiment. What should they do to get more reliable results?

• Use clay to make both soil piles.

• Pour equal amounts of water on both soil piles.

• Use sand to make both soil piles.

• Pour more water on the soil pile in tray 1 than in tray 2.

Hey there, young geologists! Remember our fun experiment with the sugar cubes and the mighty rock? So, does weathering create sediment?

• No way, because sediment is just dirt, right?

• Absolutely! Just like how the rock turned the sugar cubes into tiny particles or dust.
