The glowing crystals sensory bin is a mesmerizing activity for children. These crystals will glow in the dark, perfect for centers and for sensory play. Children will have a fun time playing with these while providing a wonderful sensory experience.
They can use different tools, such as a spoon, small containers, funnel, tweezers, etc., to scoop, pour, and transfer. Doing this will help strengthen their hand muscles and fine motor skills.
Using different colors of paint will help with children’s color recognition skills. Challenge older children to sort some of the colored salt according to color in the best possible way.
Prepare the salt by pouring a cup of Epsom salt into a plastic container. Add a few drops of fluorescent paint and mix. Repeat the process for the other colors. Let this dry.
The colored salts tend to clump when wet, but mixing them once dry will separate them.
Place these in a clean and dry bin. The site suggests adding frosted gems and flower jewelry if available. Place spoons, containers, and other tools inside the bin. Turn off the lights and turn on the black light. Let the children play.
For this activity, you will need:

A good way to introduce children to natural sources of light is through suncatcher crafts. With a science lesson, children will understand that sunlight provides enough light to reflect colors.
This craft teaches children to recognize different colors and shapes. As they cut the tissue paper, their fine motor skills will improve. The sticky part of the contact paper will provide a sensory experience for children.
To make the suncatcher, cut different colors of tissue paper in different sizes and shapes. Set these aside.
Take any color of cardstock and cut out the middle part, leaving just the border. This will become the frame for the suncatcher. Next, cut to size the contact paper to fit on the cardstock frame.
Carefully attach the contact paper to the cardstock. Press firmly to prevent them from separating. Next, have the children stick the cut-out tissue paper on the sticky side of the contact paper.
Let them make their designs using different shapes and colors to make their crafts unique.
For this activity, you will need:

This experiment challenges children to think about the different colors that may appear on a CD. With a science lesson, let children explore the light and colors as they learn to think critically with this activity.
Exploring reflections provide a first-hand experience for children as they discover new ideas and insights. Doing this will help them better understand non-concrete concepts.
Start with letting children observe the CD. Let them touch it and look at it closely. Provide guide questions for this. Ask them the colors they see and if there are any differences in the color as they tilt the CD in a different direction.
Next, find a darkly lit location inside the house. Place the CD on the floor close to the wall. Use sticky tape to stick the white paper on the wall. Turn on the flashlight and aim at the CD. The colors should reflect on the paper.
Adjust the CD if necessary. Move the flashlight to see a different effect. Ask children about the colors and patterns that they see. Children should be able to see rainbow colors reflected on the paper.
For this activity, you will need:
- Flashlight
