A first look
This shelf is still being planted — the questions are being written and checked. Come back soon. A Skill needs at least 5 checked questions before it opens here.
Question 1 of 3
Sam puts one piece of chocolate on a plate on the kitchen counter and another piece of chocolate on a plate in the fridge. After 30 minutes, which piece is most likely to be softer?
Question 2 of 3
Sam wants to find out if a plant needs sunlight to grow. He puts two identical potted bean plants in the same room. He places one pot on a windowsill where it gets sunlight and the other pot in a dark cupboard. Both plants get the same amount of water. After one week, the plant on the windowsill is taller than the plant in the cupboard. Which answer best explains Sam’s observation?
Question 3 of 3
Sam wants to find out what helps a plant grow. He puts one plant on a sunny windowsill and another plant in a dark closet for one week. After the week the plant on the windowsill is tall and green, while the plant in the dark is short and yellow. Which answer is Sam most likely to suggest?
