1. What is technology? Who are the people that make technologies? Let’s name some examples of each!

2. Technology DefinitionExamples Non-Examples Pictures An ______________________ is a person who designs technologies. Technology is anything made by people that solves a problem. engineer

3. Chicka Chicka Boom Boom Challenge

4. Science vs. Engineering SCIENCE – deals with the natural world ENGINEERING – deals with anything built by people to solve a problem. Often science and math are used.

5. Engineering Design Process Ask: What’s the problem? What have others done? What are the limits? The Goal Ask Imagine Plan Create & Test Improve Imagine: What could be some solutions? Brainstorm ideas. Choose the best one. Plan: Draw a diagram. Make a list of materials you will need. Create: Follow your plan to create it. Test it out! Improve: What worked? What did not? Make your design even better. Test it out!

6. What’s the problem in the story? Do you like to climb trees like the lower- case letters do in the story Chicka Chicka Boom Boom? Your challenge is to work with your team to design and build a tree that will be strong enough to stand on its own and hold letters!

7. Today it is your job to imagine how you can use the materials to build a tree that is strong enough to hold letters. Your second job is to work with your teammates. You’ll have to come up with a plan on how to build your team’s tree!

13. Requirements The tree must stand by itself and be as tall or taller than a ruler The tree must be made of at least two different materials The tree must have a trunk, branches, and leaves The tree must be able to hold the letters and remain standing Limitations The tree cannot be taller than the table You can use no more than five different materials to make the tree You only have three feet of tape

14.  Newspaper  Packing Peanuts  Popsicle Sticks  Pipe Cleaners  Rubberbands  Unifix cubes  Paperclips  Plastic Cups  Cereal Boxes  Straws  Three Feet of Masking Tape  Paper  Egg Cartons  Small/Big Paper Cups Optional Materials:

15. Ask : How can we build a _____________________________ that is strong enough to stand on its own and hold letters?

16. Imagine : Explore the materials. Think of each part and write what material you’d use. Draw an idea of how you can make the tree strong enough to stand on its own and hold letters. Base ? ____________________________ Trunk? ____________________________ Branches? _________________________ Leaves? ___________________________ How will you hold it all together? ______________

17. My Tree Idea

18. Challenge Jobs Builder – Draws the plan that the team agrees on. Everyone else copies it. Gives teammates directions on what to build for the tree. Videographer – Takes pictures (beginning/middle/end) and records the test. Tester – Hangs the letters on the tree. Presenter – Shares with the class the materials the team chose and how the tree was built.

19. Plan : Meet with your team. Choose the best idea, or use everybody’s ideas to develop ONE plan. Final Team Plan

21. Create/Test : Work together and use your plan to create a tree that stands on its own and holds letters. Test out the trees! Does your tree meet all of the requirements?

22. Is our tree: 1. As tall as or taller than a ruler ?.........................................................Yes or No 2. Shorter than the table ?.....................................................................Yes or No 3. Made of 2 to 5 different materials ?................................................ Yes or No 4. Made of a trunk, branches, and leaves ?...................................... Yes or No 5. Able to hold all the letters and still stand ?......................................Yes or No 6. Held together with three feet of tape or less ?................................Yes or No How many times did you circle YES ? _____ / 6

23. Improve : How could you make it better next time (diagram or words)?
