    Lesson Plan: Strawberry DNA & CSI

    In this lesson, students will extract DNA from strawberries and analyze evidence to figure out who perpetrated a petty crime.

  • Observations, Phase Changes, Combustion, Chemical Change | Middle School, Elementary School

    Demonstration: The Jumping Flame

    In this demonstration, students will observe that the vapor of an extinguished candle flame is ignitable.

  • Physical Properties, Physical Change, Chemical Change | Elementary School

    Lab: What's the Fizz?

    In this lab, students will make a lemon fizzy drink. Students will discuss what happens when things are mixed together.

    Demonstration: Inflating a Balloon with Chemistry

    In this demonstration, the teacher will perform a reaction between acetic acid (vinegar) and sodium bicarbonate (baking soda) in order to inflate a balloon and to introduce the concept of a chemical reaction to students. Students will observe the reaction, and identify indicators of chemical change as well as discuss the different types of matter that are involved.

  • Elements, Interdisciplinary, Molecular Formula, Conservation of Mass, Conservation of Matter, Molecular Structure, Balancing Equations, Reversible Reactions, Chemical Change, Matter, Photosynthesis, Monomer | Elementary School

    Lesson Plan: Plant Chemistry

    In this lesson, students will explore a simple, but key, biochemical reaction: photosynthesis.

  • Observations, Chemical Change, Reaction Rate, Reaction Rate, Catalysts, Chemical Change | Elementary School

    Lab: To What DEGREE Does it Matter

    In this lab the students will explore how factors such as temperature may influence chemical reactions. Students will use citric acid and sodium bicarbonate (Alka-Seltzer) and a catalyst (water) to induce a reaction at varying degrees. Observations will be made of the rate at which the reactions take place under these varying conditions. The students will make predictions of how the temperature of the water will affect the chemical reaction. They will use a stop watch to time the reaction between the Alka-Seltzer and the varying temperatures of water and graph their observations for analysis, they will compare data to deduce whether temperature has any influence during a chemical reaction.
