Serc: Investigating Liquids: Color Changing Milk

Students observe a molecular dance of bursting colors through exploring states of matter and learning that materials can be characterize by how they respond to water.

Here's an activity that will change how one sees color. Pupils try out an experiment on chromatography where they place a drop of food coloring on a coffee filter, add several drops of water, and watch the colors spread and separate....

Knowledge of acids and bases doesn't need to be a secret. Learners use red cabbage to create an indicator solution, then test how adding lemon juice (acid) and detergent (base) changes the color of the solution. They then use the concept...

First graders discover that a chemical reaction is responsible for the effects seen with Crayola Color Wonder markers. They observe that the color changes are the result of a chemical reaction between chemicals in the Color Wonder paper...

Student observe the effect soap (or detergent) has on the movement of food color in milk. Pupils observe the properties of solids and liquids while making butter. They read a poem, Shaking, and listen for ryhming words. Studdents...

What a great resource! This presentation is informative as is, but there are links provided to some great resources that can help learners explore the states of matter in greater depth. For example, there is a link to a website that...

Watch celery change from green to purple in a video that demonstrates how celery absorbs food coloring to change the color of the leaves. The resource has viewers thinking about the science behind types of water and photosynthesis.

A popular plant experiment where food coloring is added to the water that flowers sit in, to see how this affects the color of the flowers. It demonstrates how water travels through the xylem of a flower stem.

In this guided inquiry activity, students will use 2 marbles of different size and a box to investigate what makes the marbles move and what will cause the marbles to change speed and direction.

Background information: This activity is an extension of the children's exposure to states of matter in the Scott Foresman science series for Grade 2. This lesson has a Literacy component. Using the book by Dr. Seuss, "Bartholomew and...
