In this lab students will determine the percent composition of calcium carbonate contained in an eggshell by using a back titration in order to address a farmer’s concerns about his hen’s fragile eggs. Two versions of the student lab are included, a scripted version, and an inquiry version.

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

### Access is an AACT member benefit. Demonstration: Make a Cake!

In this demonstration, students will learn about chemical reactions by observing the differences when 4 small cakes are baked. Each recipe will differ slightly in that one important ingredient will be left out in 3 of the 4 mixtures. Students will observe and discuss what happens when things are missing or left out of a mixture and how that effects the chemical reaction.

• Concentration, Solute & Solvent, Chemical Change | Elementary School, Middle School

### Access is an AACT member benefit. Demonstration: Soft Eggs

In this demonstration, students will first observe a reaction between vinegar (acetic acid) and an egg shell (calcium carbonate) to produce a naked egg. Using these eggs, student will analyze how certain substances can move through a membrane and also determine if the membrane is affected.

• Chemical Change, Chemical Change | Elementary School

### Access is an AACT member benefit. Lab: Teeth Eggsperiment!

In this lab students will observe and analyze how different drinks can stain an egg’s shell. They will then associate the results with how these drinks can stain their teeth.

• Balancing Equations, Conservation of Mass | Middle School, High School

### Access is an AACT member benefit. Activity: Balancing Legos

In this activity students use Legos to model the reactants and products in a chemical reaction. They use these “atoms” and “molecules” to balance the chemical reaction in order to demonstrate the law of conservation of matter.

• Chemical Change, Mixtures, Reaction Rate | Elementary School

### Access is an AACT member benefit. Lab: The Disappearing Color

In this lab, students will create a solution to observe a chemical change between food coloring in water and bleach. They will also develop the process skills of predicting, observing, and measuring temperature.

• Balancing Equations, Conservation of Mass, Molecular Formula | Middle School, High School

### Access is an AACT member benefit. Lesson Plan: Counting Atoms & Balancing Equations

In this lesson, students will learn how to count atoms and how to balance chemical equations using videos, simulations and games.

• Chemical Change, Exothermic & Endothermic | High School

### Access is an AACT member benefit. Lab: Little Miss Muffet

In this lab, students make homemade glue from milk and compare it to commercial glue.

### Access is an AACT member benefit. Lab: Carbonate Identification

In this lab students use gas laws and stoichiometry, along with some balloons and simple measuring tools, to identify a metal carbonate from a short list of possibilities.

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

### Access is an AACT member benefit. Lab: Little Miss Muffet Investigation

In this lab, students will work in cooperative groups to conduct a chemical reaction by mixing vinegar with milk. This reaction will cause the curds to precipitate and separate from the liquid whey. The lesson can be extended by experimenting with different types of milk or by using different acids.

• Balancing Equations, Conservation of Mass, Photosynthesis | Middle School

In this activity, students will use candies to model the rearrangement of atoms from reactant to products during photosynthesis.

• Exothermic & Endothermic, Heat, Temperature, Classification of Reactions | Middle School, High School

### Access is an AACT member benefit. Lab: Determining Endothermic and Exothermic Reactions
