Mystery Worms

A teacher collected some beetles from a rotting log and placed them in a container of dry oatmeal in her classroom. She kept the box covered with a light cloth so that the beetles could not escape. She also asked one of her students to add potato and apple pieces once a week to provide food and moisture for the beetles. After several weeks, the student reported that there were some strange-looking, wormlike organisms in the container.

1. Formulate a hypothesis that might explain the presence of the“worms” in the container.

2. How could you test your hypothesis?

3. Identify the variables (independent and dependent) in your proposed experiment. Identify the control and experimental group in your proposed experiment.

4. What type of data (quantitative and qualitative) would you collect during your experiment?

Understanding Fossil Butte

In the southwest corner of Wyoming, there is a flat-topped mountain called Fossil Butte. A fossil of a fish was found near the top of Fossil Butte. A fossil of a fish was found near the top of Fossil

Butte in a rock formation that is about 50 million years old. Fossils of other kinds of fishes, as well as turtles, have been found at Fossil Butte. The land around Fossil Butte is dry, and the

Pacific Ocean is more than 1000 km away. How could fossils of sea-dwelling animals have formed at Fossil Butte?

1.

Think of several questions that a scientist might ask in order to understand why there are fish fossils in the desert of Wyoming.

2.

Suggest a possible answer to each question. How do your possible answers show both skepticism and openmindedness?

3.

How could a scientist go about finding an answer to each of these questions?

Do the following conversions and show all of your work. You may only use the conversion factors listed below.

60 seconds= 1minute 1 mile = 1.6 km 1 lb= 0.45 kg

60 minutes=1 hour

24 hours= 1 day

7 days= 1 week 1 inch = 2.54 cm

1.

How many seconds are you in school every week?

1 L =0.26 gallons

12 inches = 1 foot

2.

Joe and Mel are trying to determine whose car they should take down to Las Vegas (563 miles away). Joe’s tricked out Nissan Sentra Coupe gets 28 miles per gallon, while Mel’s

Cayman Porsche gets uses an average of 10 liters for every 100 km.

3.

The Pacific Giant Kelp is the longest growing kelp in the world at 197 ft long. How many millimeters (mm) is this? (Hint: For the last step use your metric conversion 1 cm =

___mm)

4.

The Pacific Giant Kelp grows at a rate of 18 in/day. How many centimeters per hour is this?

5.

Christopher Bergland holds the world record for most distance run on a treadmill in a day. He ran 247.45 km. How many miles per hour did Chris have to run to accomplish this?

6. The biggest piece of fudge ever created weighed 3010 lbs. The recommended serving of fudge is 28g. (28g = 1 serving) How many servings did this piece of fudge have?
