An interactive applet and associated web page that demonstrate the concept of a convex polygon - one where all interior angle are less than 180 degrees. The applet shows an irregular convex polygon initially. The user can drag any vertex, change the number of sides in the range 3..99, and make it regular or irregular. When the polygon is convex, the polygon is so flagged. It is shown that regular polygons are always convex. The goal is to show through experimentation what the concept of convexity really means. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

Use the "Slinky Test" to get students to start thinking about sentence length and variety.
This resource provides a video to explain the strategy and a number of supports to help you teach students when to use sentences of varied length to improve their writing.

In this work of fiction, Rooster and his eager friends set out to make strawberry shortcake, a recipe from Little Red Hen's cookbook. Rooster is glad to have help, but none of his friends know how to cook, so Rooster forges ahead to teach the helpers the basics of cooking and baking, with very funny results

Students explore the menu genre by analyzing existing menus from local restaurants. They review adjectives and descriptive writing and then work in groups to create their own custom menus.

Students learn about using renewable energy from the Sun for heating and cooking as they build and compare the performance of four solar cooker designs. They explore the concepts of insulation, reflection, absorption, conduction and convection.

Student groups are given a set of materials: cardboard, insulating materials, aluminum foil and Plexiglas, and challenged to build solar ovens. The ovens must collect and store as much of the sun's energy as possible. Students experiment with heat transfer through conduction by how well the oven is insulated and radiation by how well it absorbs solar radiation. They test the effectiveness of their designs qualitatively by baking something and quantitatively by taking periodic temperature measurements and plotting temperature vs. time graphs. To conclude, students think like engineers and analyze the solar oven's strengths and weaknesses compared to conventional ovens.

While the task as written does not explicitly use the term "unit rate," most of the work students will do amounts to finding unit rates. A recipe context works especially well since there are so many different pair-wise ratios to consider.

PHYSICAL SCIENCE, STEM CAREERS
In this video, learn from chemical engineers Laura and Wade about what it takes to become a chemical engineer and why it's a great career. Find out how chemical engineers do things like save the environment, take waste and make it useful, and solve real-world problems every day.

ABOUT THE SCIENCE
What do disposable diapers, soda, hydrogen fuel cells, aluminum, penicillin and snowboards have in common? They were all invented or further processed by a chemical engineer!
Are you someone who likes to solve problems? Do you like making something new? Do you care about the environment? If so, being a chemical engineer might just be for you!
As an engineer in this field, you get to apply chemistry to the industrial process to make things. It takes technology, innovation, and ideas to help generate an end result.
An example of this is through making textiles out of weeds! As a chemical engineer, first you would put the weeds through a processing system, have them pulped, put through an extruder to create a fiber, and then voila! You can use that to create textiles. To ensure chemical engineers are being friendly to the environment, their decision making always considers renewable resources.

Science Background:
Encourage students to be creative in their problem-solving strategies, within the scope of the rules. Students will discover that any strategy that increases the amount of heat or increases the surface area of the ice will result in a faster melt. You might ask students how they would change their strategies if the ice cube were doubled in size, if they were melting a large block of ice, or if they were melting an equal mass of ice chips.
Materials: one ice cube for each student
Directions:
Melt an ice cube as fast as you can, using the following three rules:
1. You cannot put the ice cube in your mouth
2. You must collect as much of the melted water as possible (decide how you will collect the water)
3. You can only use what is at your desk right now

Cool Kid Facts gives your child access to educational videos, pictures, quizzes, downloadable worksheets, and infographics. They can use these to learn about geography, history, science, animals, and even the human body.
