Show off treasures from your coastal travels - shadow box, map, shells sand. Use spray-mount to affix map to the back of the box. Fill the box with sand and shells you collected. DIY Tip: Make sure sand wont spill from the seams of the shadow box. If necessary, run a thin bead of wood glue along the seams to make it leak proof.
What's inside the boxes challenge which the children loved! 3 different sizes and weights which all made different noises (according to what was inside) encouraging the children to use all of their senses, and then write their guess on the box. Also great for prompting discussions with each other.
