Volcano (6-8)

"Introduction: There was a video in which a volcano goes off. In the scale, it moves 1 cm per hour. There is a map with the same volcano and same scale with a lot of cities." - A.K.

This is a Dan Meyer 3-Act Play: http://www.101qs.com/3542

Assumptions:
- The lava moves at the same rate.
- We'll measure the city at its center.

 Some questions we have chosen to investigate:
- What is the order that the lava will reach the cities?
- Is the lava increasing at a constant area or distance from the center of the volcano?
- How long will it take to reach the first city?
- How much area will be covered by the lava after _____ seconds or minutes?

This is part 1 of 2 and will require another lab day to complete our investigations.

Pizza Choice (3-5)

We have a real problem to solve today! Mrs. Korytko has commissioned us to poll the school and ask for their favorite pizza toppings. We will collect the data and decide on the best way to represent the information to help Mrs. Korytko plan her pizzas. Then we will make recommendations to Mrs. Korytko about how many of each pizza she might want to make (using the ratios we created).

Assumptions:
1) We can only survey people who will be at our school on Friday.
2) We will offer the following choices:
- meat only
- cheese only
- veggies only
- meat and cheese
- meat and veggies
- cheese and veggies
- meat, cheese, and veggies

Angry Ducks (3-5) (6-8)

Goal: To design and construct a rubber ducky launcher that can land in a giant IKEA leaf from 4 meters away. 

1) draw the design

2) construct the launcher

3) test the launcher

4) record the results of the trials

5) adjust based on results

We LOVE failure. When we fail and adjust, we act like scientists. 

The upper graders met and agreed on rules to make things fair: 

1) You must only use the materials given, but you do not need to use all the materials.

2) You may use your own strength to pull the ducky back, but you may not use your strength 

3) You are allowed 3 trials.

4) The launcher must be able to be used multiple times.

5) No ducks may be harmed in the process (no cutting the heads off the ducks). 

When you adjust your design, leave the original design in your lab. Don't cross it off, don't erase it, leave it. Write about how you changed your design so others can learn from your failures and adjustments.
