Just the name of this sweet dessert is mind-boggling! A new kitchen chemistry project at Science Buddies guides students in an exploration of this puzzling kitchen treat that melts as it cools.
Ice cream may be just the thing in summer months, cold, creamy, and sweet. But you need to eat it fast before it melts! The challenge of eating a scoop of ice cream on a cone before it drips off the sides is part of the fun of the popular frozen treat. The hotter it is outside, the more fitting ice cream may seem, and the faster your scoop will melt.
The specific "cold" properties of ice cream make it a recognizable treat, and discerning fans may be able to tell you the difference between ice cream and other frozen treat varieties like gelato, sherbet, or sorbet. Though these varieties use different recipes, they are all similar in that they are a cold, frozen treat. As they warm up, they melt.
Dippin' Dots is a novelty variation that involves flash freezing ice cream in liquid nitrogen. These small candy-like ice cream dots may not look the same as a scoop of ice cream, but they are still cold. They are fun to eat and different, but you still recognize that you are eating an ice cream treat.
New on the fun and funky desserts scene is hot ice cream, a dessert that uses kitchen science to create something completely different and unexpected.
Hot ice cream mixes things up and may play tricks on your brain!
A Hot Twist on a Cold Classic
Hot ice cream is a dessert that is solid (like a scoop of ice cream) when warm but melts when it cools. Just the opposite of ice cream in terms of its behavior in response to temperature, hot ice cream is a fun tongue teaser to make and explore. Making hot ice cream involves adding methyl cellulose to the ice cream mixture. How much do you need? How does it work? At what temperature does hot ice cream melt and how quickly? What is thermal gelling, and how can chefs and cooks take advantage of this science?
The Hot Ice Cream project guides students in making their own hot ice cream and experimenting to find the best recipe. This new food science project provides students with an in-depth procedure through which they experiment to find the amount of time needed to cook hot ice cream and investigate how the cooking time relates to how long it takes the dessert to melt.
Using the recipe in the project, families can experiment with hot ice cream this summer for an unexpected treat!
Related Kitchen Science
Hot ice cream uses molecular gastronomy science to transform a familiar food through the use of unusual, but food-safe, ingredients. Other fun molecular gastronomy food science experiments involve using spherification to turn juice into small balls (or boba) and using reverse spherification to turn yogurt into ravioli-shaped pieces.

What if there was a way to purchase materials for your classroom without having to spend your own money? Crowdfunding may be the answer! Find out tips and tricks other teachers use to successfully crowdfund for their classrooms.
With classroom budgets dwindling, teachers face an uphill battle to find funding for classroom supplies. Common bake sales, penny wars, and hat days may work for some, but other teachers find these stressful and not worth the time and planning required. To explore how teachers approach fundraising, Science Buddies sent out a recent survey to learn the ways in which teachers secure materials for their classrooms. In the survey, Science Buddies discovered that only 5% of teachers use crowdfunding, or online fundraising platforms, to raise money for classroom needs, even though teachers who use crowdfunding have had great success. So we set out to talk to teachers to get their advice on crowdfunding to raise money for school supplies.
What is crowdfunding?
Crowdfunding is a method of raising money online that involves creating a campaign for a project you'd like to have funded. Through the use of social media and crowdfunding websites, the projects you create have the potential to reach thousands of donors outside of your own network.
Why use crowdfunding?
- Crowdfunding is a great option when you need classroom materials, money for field trips, or even professional development.
- The platforms make it easy to create a fundraising campaign; just follow their step-by-step instructions.
- It's an alternative to applying for grants. The process is typically quicker, and the projects you choose to fund don't have to fit specific guidelines commonly required by grants.
What could you have funded through crowdfunding?
Science Buddies teachers have successfully used crowdfunding sites to raise money for projects including:
- Programmable robots
- A laptop
- Potato Battery Kit
- 4D model of a frog
- Water testing equipment
- Plant growing station
- Various other science supplies
We asked Science Buddies teachers who found success through crowdfunding to share their best-kept secrets:
When deciding on a project...
- The dollar amount you choose is important and can be a pivotal factor that determines whether your project gets funded.
- Increase your odds of funding with lower-priced projects. While multiple Science Buddies teachers found success posting projects that were $400 and under, Donorschoose.org notes that "projects under $200 have a 90% chance of being funded, while projects over $1000 are funded only about 43% of the time." A lower-priced project may look more appealing to donors who want to make an impact—they might even fund the entire campaign!
- Post multiple low-priced projects instead of one big one. If your goal is a class set of fifteen robots, create multiple campaigns for one or two robots since smaller campaigns are more likely to be funded than a single large one.
- Stick with a lower dollar amount if you don't have a strong network. Some crowdfunding websites have a specific time frame in which your project must be funded. For example, Donorschoose.org only allows you four months, while GoFundMe.com has no time limit.
- Don't let your school's socioeconomic status deter you. High needs schools get more press on crowdfunding websites and are more likely to be funded by people who want to make a difference.
- Tailor your projects to fit the available sponsor campaigns or Match Offers on the crowdfunding platforms. Corporations and businesses will frequently sponsor crowdfunding campaigns that align with their own missions by matching funds raised or even donating the entire amount if you raise a specific dollar minimum yourself. Another Science Buddies teacher found great success on Donorschoose.org using Match Offers; she raised over $40,000 for her classroom through this method!
- Make sure you know the rules for your school and district fundraising regulations before crowdfunding. One Science Buddies teacher said that in order to fundraise, she had to fill out a form and get approval from the principal.
While writing the project...
- Make sure to be honest and clear in all representations. Do not try to polish your situation too much to make it sound grandiose. People want to help real classrooms with real students. So try and keep the buzzwords to a minimum.
- Explain how the project will benefit your students. It is important to share how the project will reinforce their learning and help them in the future.
- Be specific about the supplies you need and what you are going to do with them.
Once your project is posted... spread the word!
- Don't be afraid to talk positively about yourself and your classroom.
- When parents ask you what they can do to help, tell them to donate to your campaign.
- Get the PTA involved and try to add information about your crowdfunding projects to school newsletters.
- Add the link to your fundraising campaigns to the end of your emails with your e-signature. The crowdfunding websites will provide this URL for you.
- Link your campaigns to your social media accounts. The crowdfunding websites will show you how to set this up. For example, after syncing your Facebook account, Donorschoose.org will automatically post to your Facebook page when someone makes a donation. This is a great way to notify your network and keep your campaign relevant.
Whether you are new to crowdfunding or a fundraising expert, we hope that these tips will help you find success in your classroom. Share this post with your friends, colleagues, or student's teachers! There may just be a person looking to support a classroom like yours right now.
Four teachers in Philadelphia received free science kits for their classrooms thanks to support from Science Buddies and VWR Foundation.
The Science Buddies Kit Club program helps provide science kits to K-12 classrooms in need throughout the U.S. By matching companies with local schools, Science Buddies supports STEM education and helps promote community STEM awareness.
The Kit Club program launched during the 2016-2017 school year. With support from sponsor companies, including Allergan Foundation, Boston Scientific, Carson Foundation, Charitable Foundation, Southern California Edison, and VWR Foundation, more than 600 science kits were distributed to 16 schools across the country during the program's first year.
STEM in Philadelphia
Thanks to a grant from the VWR Foundation, teachers in four under-served schools in Philadelphia received classroom kits through the Science Buddies Kit Club. Kit Club recipients benefiting from support provided by VWR Foundation included a third grade teacher at Mayfair Elementary School, a K-5 teacher at Horatio B Hackett Elementary School, a fifth grade teacher at William Penn Charter School, and an eighth grade teacher at Feltonville School of Arts and Sciences.
Teachers receiving Kit Club grants have the opportunity to choose 30 kits from a curated selection of science and engineering kits from the Science Buddies Store. By allowing teachers to select science kits that best meet their curriculum and student needs, the Kit Club program offers a custom solution for teachers struggling to provide hands-on materials.
Once selected by the teacher, Kit Club kits are shipped and delivered by Science Buddies, at no cost to the recipient teacher or school. In schools where access to supplies is extremely limited, this kind of support from Science Buddies and local companies can make a dramatic difference in student access to hands-on and experiential STEM learning.
Science Supplies for the Classroom
Sheryl Aurit, an eighth grade teacher at Feltonville School of Arts and Sciences, selected a mix of science kits for her classroom, including Crime Scene Chemistry, Candy Chromatography, the Ping Pong Catapult, the Sensors Kit, and Electrolyte Challenge. For Aurit, the support from Science Buddies and VWR Foundation fills an important need and makes possible a level of hands-on science inquiry that her students might otherwise not experience.
When applying for the Science Buddies Kit Club, Aurit wrote: "The major barriers to hands-on learning activities are the prohibitive cost of supplies. Most schools have no money in their budget for science supplies. Short of a bake sale there is no funding." The gift of science kits for her classroom provided Aurit with exciting materials and accompanying directions on the Science Buddies site to engage her students with science, technology, engineering, and math concepts and career opportunities.
Some of the science kits Aurit received were used by students for the annual school science fair. Other kits, Aurit selected to use and re-use in class with the more than 200 eighth grade students she teaches each week. With science kits and scientist-authored procedures from Science Buddies, Aurit's students had the chance to get hands-on with core science principles in ways that might not have been available otherwise.
According to Aurit, "Science Buddies Kit Club has given our students the opportunity to conduct meaningful investigations that are of real interest to them. The kits provided the materials to use which they might not have been able to acquire otherwise."
