How do you think mass and velocity are related to the effect and outcome of a parachute drop or egg drop container? State your initial ideas:

Guided Notes: Suppy Drop

Engineering Internship: Futura Workplace
We will work on a project for International Disaster Aid. They want to use helicopters to drop packages of water, food, and first-aid supplies in hard-to-reach places hit by natural disasters. You will use what you know about force and motion to design a supply pod that addresses three criteria.


We want to:
1. Minimize cargo damage;
a. The supply pods must be designed so that they protect the supplies inside when the pod collides with the ground. Damaged supplies will not help the people who need them.

2. Maximize shell condition;
a. The shell of the pod should be reusable after the drop. If the supply pod has almost no damage, the whole outer shell may be used as a temporary shelter for up to three people, protecting them from the sun and rain. If the supply pod is slightly damaged, pieces of the shell can be reused as building materials. If the pod is severely damaged, the shell cannot be reused.

3. Keep costs low.
a. The cost of the pod must be low so that International Disaster Aid can help as many people as possible. The lower the cost of each pod, the more pods International Disaster Aid can build and deliver.

Where have you heard the word engineer before? What kind of work do engineers do?

"I have heard the word engeineer when ..."

Practice:

Students will challenge other members of class to design the most effective and cost efficient supply drop pod. Students will analyze the following criteria in the challenge.
  1. Build section: Interns will record the design choices they make.
  2. Test section: Here, interns will record their results. Point out the screenshot of results and explain how each value is recorded in the table, if needed.
  3. Analyze section: In the Analyze section, interns should write down ideas that will help them understand where their design was successful, and where it could be improved.

Build section: Interns will record the design choices they make.

Step 1: select you design choices (shell, padding, add-ons) and record your results in the fist box
Step 2: Test your pod, and record your results in the second box

How is impact force related to the damage of the pod?
CFS:
  • accurately identifies the changes to each object in a collision
  • accurately describes the relationship between force, mass and velocity in a collision
"The more force the pod experience, the ____ (more/less) damge on the pod. This is because ..."

Exit Ticket:

Students are designing a solar oven that can be made from materials found around their homes. Solar ovens take more time to heat food than regular ovens. The students like to build solar ovens that heats food as quickly as possible.
1

For each design criterion listed in the table, write a check into 1 box to indicate whether use of the criterion will improve or reduce the rate at which the solar oven heats food.

2

Which two characteristics should the students consider when addressing the time the oven takes to heat food?
