Lesson Plan
Grade: 6th-12th
1 review
When your students think of robots, they probably think of materials like metal or plastic—but what about paper? In this lesson plan, your students will learn to make robotic parts from readily available classroom materials. Optionally, they can apply the engineering design process to improve the design or come up with their own designs.
This project is a fun way to try your hand at programming. You'll learn how to create some simple animations, and you'll perform tests and make measurements to help you create more realistic-looking animations. All you need to get started is a Web browser and a text editor (like Notepad).

Have you ever thrown away food after a meal? Have you ever thrown away a whole piece of food? What are some of the reasons you threw away that food?
During this Food Waste Audit, students will explore their own impact on our food system. Students will brainstorm solutions to reduce their food waste and be challenged to try out their solution!

Lesson Plan
Grade: 4th-8th
In these two activities, students will explore two consequences of burning fossil fuels: air pollution and the greenhouse effect. For a comprehensive unit on fossil fuels, this lesson works especially well as an extension to Fossil Fuels: Chocolate Chip Mining.

Freezing Carbonated Sparkling Water vs Distilled Water
Freezing Carbonated Sparkling Water vs Distilled Water
My science fair project is "Which liquids freeze faster?"
I froze liquids like vinegar, milk, coke, juice, lemon juice, salt water, sugar water, bottled spring water, distilled water and sparkling flavored water to see which one froze faster. I predicted the distilled water would freeze fastest because it has no added ingredients but in my first two trials the carbonated sparkling…

freezing milk vs water
freezing milk vs water
I helped my son with his science project. He wanted to know which would freeze faster milk or water. In all 3 trials the milk froze before the water. We used 3 teaspoons of each liquid. The milk froze at a average of 90 minutes and the water was an average of 125 minutes.
I thought the water would freeze first. Any reasons or ideas?
Hi,
Interesting project! There are lots of possibilities of what could cause the results you saw. It's worth…

Fresh whipped cream is the final touch for many delectable desserts. One issue with fresh whipped cream is that it has to be used soon after it is made, especially if it is at room temperature, or it starts to collapse into goo. This is a problem for its use in frostings or inside pastries as filler.
Whipped cream can be stabilized by adding unflavored gelatin. Stabilized whipped cream can be used at room temperature and it has a much longer life. But how much gelatin is just right? Try…

Fruit and Vegetable DNA
Fruit and Vegetable DNA
For my science fair project my friend and I are extracting DNA from fruits and vegetables. We already know how to do the experiment but we are stuck on a question that we are going to be solving. Our current one is "Which has more DNA, fruits or vegetables?" but it's not that good of a question.
We were deciding on doing our experiment in 2 days and still need a question. If someone could help me soon, that would be greatly appreciated cause it…

fruits as conductors
fruits as conductors
My child is doing a science fair project on fruits as conductors. Her hypothesis is that a pear will be the better conductor because of its density. She came to that conclusion after some research on why a potato always seems to be the top produce for experiments on electricity. She found that the density of the potato makes it a good conductor. Since the inside of the potato is similar to the pear, she deduced that it would be the best fruit for…
