This is a gizmo you learn in physics I called pattern finding)...

Description

Name:

Date:

Student Exploration: Pattern Finder Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: experiment, hypothesis, observe, prediction, theory Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. What is the order of the seasons?

spring summer fall winter

2. A traffic light is green. What color will it be next?

Orange

3. If today is Wednesday, what day will it be 9 days from now?

Friday

4. What do seasons, traffic lights, and days of the week all have in common?

They all have a specific pattern that they follow

Gizmo Warm-up The Pattern Finder Gizmo lets you find and test patterns by observing frogs hop around a set of lily pads. 1. Grab the blue frog and drop it on any lily pad you want. Observe the frog. Describe a pattern you find. If the blue frog is not in a red pad, it will move to the red pad and keep jumping on the red. If the blue frog is in a red pad then it will always jump on a red pad. 2. Click Catch all. Grab the blue frog and put it on a few different pads. Does it follow the same pattern? It follows the same pattern 3. Predict what color lily pad it will go to if placed on the pad in the top-left corner. Red-coloured lily pad. 4. Put the blue frog on the pad in the top-left corner. What color does it jump to? It jumped to the red one. Reproduction for educational use only. Public sharing or posting prohibited. © 2020 ExploreLearning™ All rights reserved

5. You just ran an experiment to test a pattern. Was your prediction correct? Yes, the experiment I ran was correct.

Activity A: Get the Gizmo ready: Observing patterns

● Click Catch all.

Question: How do we find patterns? 1. Collect data: Place the brown frog on any blue lily pad. Record the colors of the lily pads it visits in order. Write R for red, B for blue, and G for green. Record the first 15 hops. R -G -B repeat 2. Analyze: Put the brown frog on other pads and watch. What pattern does it seem to follow? The pattern seems to follow. 3. Observe: Click Catch all and repeat the above steps with the pink frog. A.What pattern does the pink frog follow?

It will jump to the colour of the original pad it was.

B.Does its pattern depend on where it starts? Explain.

Yes, it does as the start depends on the colour it jumps to.

4. Find the pattern: What pattern does the yellow frog follow? G - B - B - R repeat 5. Extend: Describe the red frog’s pattern. If Red frog is in red then it will jump to the reds If Red frog isn’t in red then it will jump to Green - Blue and repeat

6. Challenge: Compare the purple and red frogs. (Hint: Pay attention to more than just color.) A. How are their patterns similar?

If frogs are in red they jump to red but if not they jump from Green to blue

B. How are they different?

Activity B:

The purple frog jumps longer

Testing patterns

● Select Advanced. ● Click Catch all.

Question: How can we gain confidence in the patterns we see? 1. Form hypothesis: Put the yellow frog on any pad. Observe it carefully. Try it on other pads. When you think you understand the frog’s behavior, write your belief, or hypothesis, below. If the yellow frog is placed in the green pad then it will jump from red to green back and forth. 2. Predict: The true test of a hypothesis is if it predicts the results of experiments you have not yet tried. You should not trust a pattern until it correctly predicts the results of a test. Use your hypothesis to fill in the two sentences below. A. From the blue pad at lower left, the yellow frog will next jump to a B. From the red pad at lower right, the yellow frog will next jump to a

Green Blue

3. Test: Run experiments to test your predictions. Were you correct both times? Yes i was correct both times.

● ● ●

If one of your predictions was wrong, your hypothesis has been disproven. If your predictions were correct, your tests support your hypothesis. If enough experiments support a hypothesis, it can become a theory.

4. Form hypothesis: Now observe the pink frog carefully. What pattern does it repeat? GRBGRBGRRB 5. Predict: What are the next 10 colors the pink frog will visit if you start it at the bottom left? GRBGRBGRRB

pad. pad.

6. Test: Test your hypothesis. What happened? It went on the colors. 7. Challenge: Can you ever absolutely prove that a hypothesis is correct? Explain. No since there can we an experiements that rejects the hypothesis.

Activity C: Using patterns

Get the Gizmo ready: ● Select Advanced. ● Click Catch all.

Question: How can we use patterns to answer questions? 1. Find a pattern: Place the blue frog on any pad and observe it. What pattern does it follow? B B B G R R G G G repeat 2. Analyze: No matter where it starts, what color will it visit least in its first 20 jumps? Why? All the colours because of their pattern.

3. Observe: Click Catch all. Observe the red frog. What rules does it appear to follow? It will only jump to red and blue.

4. Analyze: Think about what will happen if you drop the red frog on a green pad. A. What color will it never hit? Explain.

It will never hit red. This is because it will jump from green to blue.

B. Starting on green, what color will the red frog spend most of its time on?

It will spend most of its time in green.

C. Explain.

It spends 1 second more time in the green.

5. Observe: Click Catch all. Observe the purple frog. What rules does it appear to follow? It doesn’t appear to follow any rule but sometime later it will only go to the red pad.

6. Challenge: Suppose you drop the purple frog on a green lily pad. Will it be easier to predict the color it will be on after 1 jump or after 4 jumps? Explain. I don’t think it’s easier to predict as it’s very inconsistent.
