good morning. i am looking for a science fair project for my son who is in kindergarten.

polymers and monomer structure

What about floating vs sinking. Using common house hold objects like a rock, penny, small plastic bottle, and anything else you can find. Then drop them into a bucket of water and time how long it takes them to sink. Its easy and you won't have to buy supplies.

put one white flower in a vase with 5 cups of water and one white flower in a vase with 5 cups of water with food coloring (red green blue yellow or any color) for one week.

make sure you take pictures and write a few sentences on what you noticed (since he's only in kindergarten it won't be much)
Make sure you measure the amount of water, minutes in the sunlight, and how long you have been growing them, those will be the controlled variables.

Good morning! I'd be happy to help you find a science fair project for your kindergartener. When thinking about projects for young children, it's important to choose activities that are simple, hands-on, and engaging. Here are a few ideas to get you started:

1. Exploring Sink or Float: Gather different objects such as toys, fruits, and household items. Encourage your child to predict whether each item will sink or float in a bowl of water. Help them understand the concept of buoyancy by observing and discussing their findings.

2. Making Slime: This is always a crowd-pleaser! You can find simple slime recipes online using household ingredients like glue, borax, or liquid starch. Your child can experiment by adding different colors or textures to the slime and observe how it affects its properties.

3. Investigating Magnetism: Collect a variety of objects, some of which are magnetic (e.g., paperclips, coins) and some that are not (e.g., pencils, plastic toys). Help your child explore which objects are attracted to a magnet and why. They can then create a display to showcase their findings.

4. Exploring Plant Growth: Have your child plant a few seeds in different pots using different materials (e.g., soil, sand, cotton balls). Help them observe and document the growth of each plant over time, discussing the factors that contribute to healthy plant growth.

Remember, the objective of a science fair project at this age is to encourage curiosity, exploration, and observation. It's important to focus more on the process than on specific results. Have fun and enjoy the learning experience with your child!
