A. Question: What makes the diver go up and down?

B What we already know: The diver moved when….

C. Hypothesis: The magnet attracts the diver and makes it sink BECAUSE…... Skip 1 line

D.Record basic observations of the behavior of the diver.

Record at least three questions about the diver.

We know Questions

Use no more than 7 lines

E. Conclusion The diver goes up or down because of …….

My evidence/data for this is the observation that….

My initial hypothesis was (right or wrong) because…

F. Write and draw out your explanation of how the diver works

G. What is it about squeezing the bottle that suddenly makes something that floats sink?

G. Squeezing the bottle…….

What combination of air and water is best to make a diver sink and float easily?

Can you make a diver out of other materials?

USING PHOTOGATES TO TIME CARS 9/16/11Top half of page: Draw/color a labeled picture of how to

set it up.– Label: ramp, car, photogate A,B, draw red and blue

wires.

• Answer in a paragraph- bottom half of page.

How should the photogates be set up for timing cars:

1. Should the timer be on stopwatch or interval?2. Should light A, B or both be on?3. Which photogate should be nearest to the top of

the ramp, A or B?Describe what happens to the timer when a

car rolls – down ramp THROUGH 1st PHOTOGATE

(PG), – between the 2 PG’s and – THROUGH THE 2nd PG.

scientist changes to see if it changes the results.Skip 1b. Which is the experimental variable?Skip 1c. All other variables should be….

How should the other variables be set at the beginning of the experiment? Why?

Underline the word “because” in your answer.

Skip 1

Conclusion: Was your hypothesis correct? Why or why not: Discuss the way variables were changed in the experiment

Steepness & Car Times 9/19/11

Which tables’ tracks will have the shortest time ? _______Skip 12. Hypothesis: (Underline the words: TIME STEEPER BECAUSE) One sentence.If the ramp is steeper, the car’s time will be ….. BECAUSE….

3. DATA: Car Times: ______, _____, ______, _______


pg. 17: THE EXPERIMENT DONE RIGHT! Name:

1. How should the experiment be set up different?– Do not push car– Photogates at same spots– Pointy end first– No extra weight

down a ramp? Skip 1 line2. Hypothesis:If we increase the mass of the car, it will ………. Because…

Skip 1 line3. Experimental Variable: Weight of car (# of marbles)4. Dependent Variable: measure time to get from A to B

Data Table:

Page 18: Mass/time analysis

Conclusion: Answer the problem. List some evidence for your conclusion. Does data support hypothesis? Why or why not?

Analysis

1. Explain why the CAR MASS was the experimental variable in this experiment, but RAMP STEEPNESS was the experimental variable in the previous experiment.

2. How and why were variables controlled (to make it a fair test?) Did the CONTROLLED VARIABLES in this experiment affect the TIME down the ramp? Why or why not?

3. Some sort of concluding sentence ( “I wonder if…”., or “ It was surprising that…”, or I learned that…”

A good graph has:

•Descriptive Title

•Axes labelled

•Line drawn/ Bars colored

• Controlled variables • Why controlled

•Magic diver(P. 8-9)

•Why does the divergo up or down?

•The use of the magnet totry to move it.

•The magnet has no effect

•No hand squeezingpressure on the bottle.

Loop Flyer- Graph and conclusions 9-30-11

Conclusion: Which was the best design and why?

• Explain your hypothesis and the changes you made. Did the change make it go farther?

• Describe which design flew better and why you think this happened

• What variables did you control: name 4 variables that could have affected the outcome

• Which variables were difficult to control….

Problem: Which Loop Flyer design results in the “best” flight?

Variable: Something that changes and affects the outcome of an experiment.

Controlled Variables: (Kept the same so it is a fair test): List:•Throwing force Throwing direction/angle

•Wind Straw length

•Loop diameter Distance between loops

•Number of loops •The ONE variable we are changing is: ___________




Conclusion :Label paper cups: R and B for red and blue. Mark a line about 1/3 of the way from bottomPut 1 level tsp of each mix in your cups. Test the aroma (use correct technique) and appearance of each. Record ratings.Use the toothpick to taste each dry mix. Record ratings.Mix with water: Recipe Don't mix up the spoons.1 level tsp. powder + 1/3 of the small cup of warm

water. STIR WITH TOOTHPICK!!
