Bio & IPC 2B: The student is expected to collect Bio & IPC 2B: The student is expected to collect data and make measurements with precision.data and make measurements with precision.

Students used a balance to measure a sample of soil. What is the mass of the soil?

A. 206 g

B. 216 g

C. 263 g

D. 320 g

The solution is to subtract the mass of the empty container from the mass of the container with the soil. 263 g – 57g = 206 g. The answer is A.

On the 2nd 6 weeks common assessment over ¼ of the students chose C.

Based on this observation, which is on this observation, which is the most valid conclusion?the most valid conclusion?

A.A. The frogs must be able to jump The frogs must be able to jump really well.really well.

B.B. These aren’t frogs but a new These aren’t frogs but a new unknown species of amphibian.unknown species of amphibian.

C.C. There must be pollution in the There must be pollution in the lake causing the frogs to lake causing the frogs to change.change.

D.D. There is not enough data to There is not enough data to make a conclusion.make a conclusion.

The correct answer is D.

This observation is startling but more observation and experimentation is necessary to determine exactly what has happened to the frogs in this lake.

The ciliate in the picture has a mass of 2 X 10The ciliate in the picture has a mass of 2 X 10--

55 kg (.00002 g). If it is accelerating 0 to kg (.00002 g). If it is accelerating 0 to 12 mm per minute (60 seconds), what 12 mm per minute (60 seconds), what force is it applying?force is it applying?

(Hint: Force = mass X acceleration or F = (Hint: Force = mass X acceleration or F = mXa)mXa)

A.A. 2.4 x102.4 x10-4 -4 NN

B.B. 3.0 N3.0 N

C.C. .12 N.12 N

D.D. 6.6 X 106.6 X 10-11-11 N N

The correct answer is D.

.00002 kg X .012 m/60s2 = 6.6 x 10-11 N

For this problem you must convert 12 mm to meters and 60 must be squared because acceleration is expressed in meters per second squared. This is a hard question but you will get things like this in TAKS.

This is an example of Newton’s 2nd law of motion.
