JHU Opportunity Journal -- Sam on Things He Wishes He Had Known Sooner
Freshman Sam Cook and his floor mates give some examples of things they wish they had known in preparation to coming to Johns Hopkins.
Make Your Own Earth Science Stationery
These OLogy stationery files give kids a fun way to communicate their Earth science knowledge. Two ready-to-print letterheads are provided as downloadable PDFs. They include colorful looks at: an erupting volcano, a stalactite, and stalagmite-filled cave

Americans experiment with mobile-phone money, the E8 internet summit in Paris and the web bubble gets bigger
Stress, Inc.
Students explore the physical and psychological effect of stress and tension on human beings. Concepts of stress and stress management are introduced. Students discover how perception serves to fuel a huge industry dedicated to minimizing risk and relieving stress. Students complete a writing activity focused on developing critical thinking skills. Note: The literacy activities for the Mechanics unit are based on physical themes that have broad application to our experience in the world concepts

Provide planted area care
This unit focuses on the care of planted areas including
weed control, watering plants, fertilising plants and the contol of pests and
diseases. Topic areas include: weeds and their characteristics, tools and methods
used for removing and controlling weeds, processing and disposing of weeds, tidying
up the worksite, plant water needs, categorising plants according to their water
demand, water stress, watering methods and devices, plant nutrients, fertiliser
formulations,
7.4 Evaluating your strategy and assessing your work Present a reflective summary that gives details of: a judgement of your own progress and performance in the IT skills you set out to improve, including an assessment of where you feel you have made the greatest progress; discuss your use of criteria and feedback comments to help you assess your progress; those factors that had the greatest effect on you achieving what you set out to do; include those that worked well to help you impro
7.2 Brushing up on your computer skills
The internet is a fantastic source of information for any student, but how do you evaluate the information each site provides? This unit will help you assess the benefits of information technology, providing guidance on the protocols for using email, online conferencing and real time chat as methods of communication.
4.8 Not everyone is participating
The internet is a fantastic source of information for any student, but how do you evaluate the information each site provides?

Becoming a Mosquito
Join students as they observe mosquitoes in different stages of development and learn about the insect's life cycle in this video from Curious George.
Live like an Animal
In this activity, students design an innovative human shelter that is inspired and informed by an animal structure. Each group is assigned an animal class, and they gather information about shelters used by the animals in that class. After researching the topic and brainstorming ideas, students build small prototypes (models) of the structures. Finally, they present their products, explaining what attribute of the animal structure influenced their design.
Leaning Tower of Pasta
Using spaghetti and marshmallows, students experiment with different structures to determine which ones are able to handle the greatest amount of load. Their experiments help them to further understand the effects that compression and tension forces have with respect to the strength of structures. Spaghetti cannot hold much tension or compression; therefore, it breaks very easily. Marshmallows handle compression well, but do not hold up to tension.
Food Packaging
This lesson focuses on how food packages are designed and made. Students will learn three of the main functions of a food package. They will learn what is necessary of the design and materials of a package to keep food clean, protect or aid in the physical and chemical changes that can take place in a food, and identify a food appealingly. Then, in the associated activity, the students will have the opportunity to become packaging engineers by designing and building their own food package for a
Space Travel
In this lesson, students are introduced to the historical motivation for space exploration. They learn about the International Space Station as an example of recent space travel innovation and are introduced to new and futuristic ideas that space engineers are currently working on to propel space research far into the future!
Flow Rates of Faucets and Rivers
In the Flow Rate Experiment, students perform hands-on experiments with a common faucet, as well as work with the Engineering Our Water Living Lab to gain a better understanding of flow rate and how it pertains to engineering and applied science. Students calculate the flow rate of a faucet for three different levels (quarter blast, half blast, and full blast). Building on these calculations, students hypothesize about the flow rate in a nearby river, and then use the Engineering Our Water Livin
Hovercraft Racers!
Students gain first-hand experience on how friction affects motion. They build a hovercraft using air from a balloon to levitate a craft made from a compact disc (CD), learning that a bed of air under an object significantly reduces the friction as it slides over a surface.
A Place in Space
The students will use a "real" 3D coordinate system. They will have 3 axes at right angles, and a plane (the XY plane) that will be able to slide up and down the Z axis. The students will then be given several coordinates and asked to find these points in space. They will also be asked to find the coordinates of the 8 corners of a box with given dimensions.
Power, Work and the Waterwheel
Waterwheels are devices that generate power and do work. Students construct a waterwheel using two-liter bottles, dowel rods and index cards, and calculate the power created and work done by them.
