• Eats plants or other animals for food

• Makes its own food

• Machine that gathers trash

Bonus BIOLOGY: In humans, backflow of blood from ventricles into atria during contraction is prevented primarily by what structures?

What force causing a basketball to fall to the ground?

• Friction

• Magnestism

• Gravity

A group of farmers worked with scientists at the local university to find an inexpensive solution to protect the rich soil of their farmland from erosion by water due to rain and irrigation. They set up their investigation in 4 plots of farmland located next to each other with the following variables in place meant to slow the amount of erosion (see table.) When the group finished their investigation, they published their detailed procedures and conclusions. Why was it important for the group to publish their procedures and conclusions from their investigation?

• So other farmers are able to decide which crop to plant.

• So other scientists are able to replicate the invesigation.

• So other farmers are able to grow crops in their own plot.

• So other scientists area able to record the amount of watering that occurred.

Is this a complete circuit?

• Yes

• No

A mushroom is a 

• producer

• consumer

• decomposer

Scientists found the fossil below with webbed feet. The animal most likely lived in what type of habitat?

• in the mountains

• in the desert

• in the tropical rainforest

• in a pond, lake, or ocean

The students in Mrs. Shapiro's class are experimenting to see whether different types of soil affect the growth of plants. They plant three seedlings in sandy soil, three more in clay soil and three more in topsoil. They give each plant the same amount of water and place the plants in a sunny window as shown in the picture. After two weeks, the students observe that the plants in the topsoil grew best. Which of the following is evidence on which the students will base their conclusions?

• observations and drawings of the seeds

• description of the procedures for the investigation

• predictions the students made before the investigation

• height of the plants growing in each of the different soils
