With this Einstein Box, your kid will dive into the fascinating world of chemistry and material science. Fizzy magic potions, color changing liquids, fragrant soaps or self-grown crystals - the engaging and colorful experiments will help your children understand the basic principles of science. The instructions are straight-forward and easy to follow, so that your kids will be able to do the experiments all by themselves. Lean back and let your little chemists explore!

The kit includes the materials necessary for 15 experiments. The manual includes instructions for another 25 experiments, which you can easily do with household items.

Building an erupting volcano, launching a rocket, making pop crystal fireworks, causing colorful and fizzy chemical reactions - this kit will give your kids the chance to discover the fascinating world of chemistry.

The kit includes the materials needed for 15 experiments with instructions for an additional 30 experiments, all using common household items like baking soda or vinegar. The experiment guide contains illustrated, step-by-step instructions that are easy to understand and follow. Your kid will conduct their own experiments, just like a real scientist! The guide also includes details about the chemical reactions, so that your little scientists will spend hours experimenting and learning about chemistry. However, we do recommend that these are done with adult supervision as chemicals are involved.

Let your kids discover the invisible world with this beginner-friendly compound microscope. It offers six adjustable magnifications up to 1200x. The microscope comes in a hard-sided plastic case, making it the ideal portable equipment for your little explorer to carry around. The microscope comes with 49 accessories like tweezers and reusable slides and cover glasses that allow your kid to easily set up their own microscopy experiments.

The kit also contains five prepared microscopy slides, so that your children can immediately get a glimpse of the fine-grained structures of for example a fish scale or a bean leaf. Included in the kit is also an entire brine shrimp experiment allowing your children to observe the life cycle of these ocean creatures. With this kit, your kids will gain hands-on experience with the scientific method: setting up an experiment, analyzing and documenting the outcome. We love this microscope so much that it tops our best microscopes for kids list!

Give your children the joy of having their own science lab station, where they can conduct exciting chemistry experiments. The lab station is easy to assemble and reconfigure for different experiments with a helping hand from an adult. The kit contains all materials needed for 20 cool science experiments – invisible ink, self-inflating balloons, glowing slime, rainbow in a test tube, and more! Like a lot of other sets, some experiments will require common household items like scissors, tape, or salt.

Instructions for half of the included experiments are printed on cards that can be directly clipped onto the lab station for quick reference. There’s also a 16-page, full-color manual that contains detailed instructions as well as easy-to-understand explanations so that your budding scientists can learn the science behind the experiments and how they apply to everyday life.

Show your kids the fascinating world of both geology and chemistry by letting them grow their own crystals. This kit, selected by the University of Cambridge no less, provides all materials needed for seven different crystal growth experiments. Once fully grown, these stunning crystals can then be proudly shown off in the provided display cases. The detailed instructions are easy to follow and the experiments are straightforward to set up.

Adult supervision is required for setting up the experiments as this involves boiling water. The crystals start forming in about five hours after set-up and will reach their full size in 7-10 days. The included fact sheet provides additional information on crystal growth. We really like this one as it provides a beautiful, tangible result that you can admire for years to come.

Teach young minds about the mechanics behind levers and linkages and how they can be used to lift heavy objects with this lovely kit. In 16 hands-on activities your kids will build different structures such as a wheelbarrow, a parking gate, and a movable weight scale.
