What is evaporation?

Students have two blocks the same size. They drop each block into a beaker of water. Why does block 1 float and block 2 sink?
What is Block 1 is a different material than block 2?

Butterflies get food from the flowers of a plant. They also lay their eggs on the leaves of the plant. As the caterpillars develop, they eat the leaves of the plant. How does the plant benefit from butterflies?
What is the Butterflies help pollinate flowers so that seeds can form?

A class observed grasshoppers, frogs, mice, snakes, and owls in a grassy field. They are all part of the same food web. Students combined their observations of what the organisms eat in the table. grasshopper ------------- grass mouse --------------------grass, grasshoppers frog----------------------- grasshoppers snake--------------------- grasshoppers, mice, frogs owl ------------------------grasshoppers, mice, frogs, snakes Draw a food web with four of these organisms. When drawing the food web, be sure to use the names of the four organisms and draw arrows to trace the energy flow among the organisms.
The response provides a complete food web drawing, which includes at least four combinations of organisms. The food web uses the names of at least four organisms, including a producer (grass), and shows all relationships among the organisms identified. The arrows are drawn in the correct direction to show the organization and flow of energy among the organisms.

A student asks, “Does the size of the wheels affect how far toy cars roll on the floor?” The student hypothesizes that toy cars with large wheels roll farther. The student wants to make sure that the force that starts the cars moving is always the same. Describe or draw how the student can set up an investigation of his hypothesis. Then, describe or draw how the student can collect data to support his hypothesis.
1. The student can set up a ramp with the car on top. At the bottom of the ramp would be a track for the car to run on and next to the track would be a tape measure to measure how far it would go. 2. The student can run the same car with different sized wheels to see how far it goes each time.

What is X ->Y <- Z?
