Valentine Candy Heart Science And STEM | A Density And Buoyancy Lab Grade 2 3

This complete unit introduces density and buoyancy. Valentine-themed to create even more excitement. Aligned to NGSS 2nd/3rd Grade with teacher background guidance. Jam-packed with an investigation, exploration, and STEM challenge using simple supplies. Budget-friendly and fun. Learn how candy hearts are like life jackets.

Please note this experiment works best with the classic Necco Sweethearts which are now sold by SpanglerCandy (Also called Sweethearts Candies the Originals) or Brach's Tiny Conversation Hearts. However, we can not guarantee how the hearts will work. Make sure you test the experiment first and have raisins as a backup plan. Companies do change their recipe, and different brands of soda pop may act differently. This experiment is so much fun, but we want to make sure you have the correct supplies. Always remember this is science, and things may not always go as planned. We will provide you with lots of tips to improve success.

This density and buoyancy unit has it all. You can teach all three hands-on activities or pick and choose. I recommend starting with the investigation and completing one or both of the challenges. The classic dancing raisin experiment has been taken up a notch by using candy hearts. The integration of an independent and dependent variable makes it meet *NGSS Science and Engineering Practices. Students follow the scientific method in a journal created for their age level. After the investigation, students will relate it to the real world by learning how life jackets work. The science behind dancing candy hearts will amaze you and your students.

Provided is a further exploration challenge where students compare diet soda to regular soda. Students use their data and observations as evidence in providing similarities and differences.

A STEM challenge is included. Students will try to create a liquid that will increase the candy hearts dancing. They will use what they learned in the investigation to guide them.

Uses simple and easily available supplies: Tall glasses, oil, Necc Sweethearts, diet soda, regular soda, stopwatch, paper towels, and other materials you choose for the STEM Challenge.

This investigation is part of a series. This is the 2nd/3rd-grade investigation. K/1st and 4th/5th are also available. Each version is differentiated for abilities and the NGSS. K/1st tests with and without carbonation and includes exploration station ideas. 2nd/3rd grade increases the carbonation to 3 levels and includes an exploration challenge and a STEM challenge. 4th/5th grade increases the carbonation with one more level and completes 3 trials. It also contains the exploration challenge and the STEM challenge.

We hope you will enjoy this density and buoyancy unit as much as we do. It checks the boxes on the standards and allows the teacher to have a holiday-themed lesson. The included standards will allow you to impress administrators. I picked apart the science and even uncovered a little ingredient to make the lab more successful.
