The Eclipse is a VISUAL event. Don’t be disappointed with cheap glasses that are safe but provide a washed out, hazy view of the Sun. Buy glasses that are manufactured using the highest quality film that provides crisp, clean, and pleasant view of the Sun in even slightly overcast conditions.

Sep 9, 2017 — The magnification formula: 1/S1 + 1/S2 = 1/F. This is a formula for a thin lens, but still works, although for complex zoom and/or inner focus ...

Many competitive products only pass the safe transmission requirements using very low quality film that do NOT provide a clear image of the Sun.

How to makeeclipse viewerwith cereal box

If you don’t have a magnifying glass in your home, you can find one pretty cheap and explore what other things look like up close. Make things even more scientific by handing over some crayons and paper so your child can write down what they discover. (Feel free to give them a little white smock to really set the scene.)

Next time you’re snuggling with your kids under your favorite warm blanket, grab the magnifying glass to examine the fibers keeping the blanket together. Is there a pattern to the fibers? Once they’ve had an eyeful, encourage them to take a look at other fabrics around the room to compare—like maybe their T-shirt, socks, or even the couch itself!

That’s why this week in our centers, we’re taking kids out into the fresh spring air to take a closer look at the natural world popping up around them—and when we say a closer look, we mean really close.

Choosing the right child care center is important, and we know life can be hectic. Take a quick virtual tour and see our center from the comfort of home!

Is your child shaking some salt onto her green beans? Before they dig in, encourage them to take a peek at a couple of those salt crystals. What do the granules look like up close? For that matter, what do the beans look like up close? (If they really can’t wait, though, let them eat—science can be put on hold for a growling tummy.)

If you have questions about tuition and openings or want to schedule a tour, tell us about yourself and we will contact you shortly.

“At this age, children’s critical-thinking skills and fine-motor skills have developed to the point where they can start using simple tools,” says Meg Davis from KinderCare’s Education team. Magnifying glasses help kids see things they’ve never seen before, like small insects close-up. It opens up a whole new world to them, which they find pretty amazing!

Are you helping your child brush their hair before bed? Sneak in some science before story time by looking at several strands of their hair and your hair up close. At normal eye level, hair looks smooth and fine—but what about up close? What does your child see? How is their hair different from your hair?

Labelling: ISO verification requires that the Contact Information of the manufacturer be printed on the product. A Logo or a Brand Name does not qualify. Products that do not have a manufacturers address are NOT compliant with current ISO 12312-2 requirements.

Water and its various forms are intriguing to kids—so encourage your child to take a closer look at ice for a real “wow” experience. You both might be dazzled by the ice-crystal patterns and the shades of white and blue. Turns out a cube is pretty complex! Extend the learning even further by talking about the ways water can turn from liquid to ice and back again!

There’s a reason we give kids journals to write things down—beyond building literacy skills. Getting children used to recording their findings sets them up for success in their science studies later in life (and gives them a head start on learning the scientific method, whether they realize it or not).

Young children’s brains are hardwired for exploration and observation—two things that just so happen to be early science skills. By around age four or five, however, their scientific abilities really start to take off because they’re old enough to start using cool scientific tools.

At KinderCare, we’re committed to building warm, welcoming and supportive classrooms for children of all abilities, backgrounds and experiences.

Fresnel lens mini magnifier - 10" x 7": Flexible and lightweight magnifier, an amazing fire starter, use for solar cooking and heating- thousands of uses.

With magnifying glasses and journals, children work together to examine whatever they find—from leaves and soil to pebbles and ants. They then write about or draw pictures of what they see—which gives these young scientists a literacy-skills boost.
