This document discusses how rocket launches can be used to teach students experimental design. It provides a 7-step process for developing rocket design labs: 1) Get equipment; 2) Familiarize students with equipment; 3) Brainstorm variables; 4) Provide examples; 5) Have students write designs; 6) Provide feedback; 7) Conduct experiments. Examples of student lab designs are included to illustrate the process. The importance of experimental design is discussed in relation to science standards.

Adding the "TEM" to our Science Teaching: STEM mom gives tips for inquiry and...Darci the STEM Mom
Darci, the STEM Mom presented this powerpoint as part of a 3 hour workshop at the 2013 Minnesota Science Teachers State Conference. She challenges science teachers with six hands-on inquiry activities that engage students with not only science principles but also engineering, technology, and mathematics. STEM Mom also addresses the meaning of STEM, use and purpose of Lab Notebooks, how to create an environment friendly for inquiry, and how to modify lessons to be a higher level of inquiry. For each of the six challenges, STEM Mom provides a teacher lesson plan, tips for presenting the challenge at various levels, and two versions of student handouts.

Week 1 Laboratory Assignment
In this lab we will investigate the use of direction fields to evaluate solutions to first order differential equations.
For this lab, we will study these qualitative analysis tools via the example of population growth using the Gompertz equation as a model. This equation is used to model the growth of tumor cells, and gives an expression of the dependence of tumor size on time.
The differential equation governing the growth is:
Here is the growth rate is a reflection of the carrying capacity of the tumor.
Let ; ; and V range from 0 to 100
1. Plot the graph of vs. . Note you may have to use the vectorization operator “.” to evaluate the function of the differential equation.
2. Determine the equilibrium points (by-hand or MATLAB) and plot them on the same graph as part (1) using red circles. Use a legend to indicate the equilibrium points and the original plot.
3. Using the gradient() function, plot the derivative of versus on the same plot. That is, plot vs. .
4. Determine the stability of each equilibrium point and the region of attraction. Write these answers as comments in your code. Comment on the stability as it related to the graph.
5. From this graph, are we able to tell how long the tumor will take to grow to units if the initial size is units? Why? Write your answers as comments in the code.
We will now use the direction field tool to examine the solution.
6. Download the file from the course website in the MATLAB Resources folder. You may have to right-click and save the file to your computer. IMPORTANT! Make sure it is in the current directory you are working in.
OR
Access the dfield tools at http://math.rice.edu/~dfield/dfpp.html
7. Using the same parameters as above, plot the direction field of this differential equation. Set the time and variable limits appropriately.
8. Compare your results from part (4) to the direction field obtained to check: the stability of each equilibrium point and the region of attraction. Include these as comments in your code.
9. Estimate how long it will take for if. Hint: You can go to: WINDOW DFIELD Keyboard Input to enter the initial conditions.
10. Repeat the direction field plot with and estimate again how long it takes for if . Comment on your results as they compare to part (9).

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

26. My Feedback Sheet G4IA Assessment sheet 11/3/2008 Student: Gonzales, Jose Investigation: Rocket Design Lab Time: 2Hrs Date(s): 08/01/08 Design General comments Ringo Dingrando 2 Defining the problem and selecting variables You formulated a research question and identified the relevant variables. Great idea to change the center of gravity of the rocket! No one else thought of that! Great sketch graph to help visualize your hypothesis. 1 Controlling variables You do not effectively control variables. By adding extra tape to the tail every time, you WILL change the center of mass, but you are ALSO changing the very important variable of rocket mass. 1 Describing a method for collection of data :) Excellent drawing. You do not state the increments of your independent variable measurements. You do not list the range of your measurements. It is quite clear how and where you intend to add the mass, but how much tape each time? What will be your maximum amount? What about multiple trials? 4 This criteria is only addressed This grade will not appear on the PSOW You are making similar mistakes as you did on previous labs. Please see the feedback on previous labs before you do your next one!
